Customs Self-Filing: What Moves to You When the Broker Steps Out

Self-filing means the importer or exporter is the declarant: the goods declaration is lodged in their own name, with no representative appointed. The right to choose that is an international standard — Revised Kyoto Convention General Annex Standard 8.1 gives persons concerned "the choice of transacting business with the Customs either directly or by designating a third party" — but the conditions are set nationally (Standards 8.2 and 3.6), and the direct/indirect split used below is a Union Customs Code construct rather than a universal one: whether your administration recognises it, and what each arrangement entails, is national. What changes when you switch is narrower than it sounds. Under direct representation you were already the declarant, so accuracy liability does not arrive — it loses the second party who was bound alongside you (UCC Art. 15(2)). Under indirect representation you lose a co-debtor for the customs debt (UCC Art. 77(3), which governs debts incurred on release for free circulation and temporary admission with partial relief; non-compliance debts have their own debtor set in Art. 79(3)). What does move is performance: supplying every data element and being able to present the goods (Art. 170(1)), holding supporting documents at the moment of lodgement (Art. 163(1)), retaining them for the national period (Art. 51(1)), and holding in your own name any simplification authorisation you had been using through a representative (Arts. 166(2), 182(1)). And the switch is not atomic — post-release control, guarantees, open transit, undischarged procedures, unlodged supplementary declarations and pending applications close on their own events, not on your cutover date. Thresholds, fees, licences and system-conformance requirements are national — confirm with your customs authority.

What does "customs self-filing" actually mean?

• Self-filing means the importer or exporter is the declarant: the goods declaration is lodged in their own name, with nobody appointed to act for them. The Revised Kyoto Convention defines the declarant as "any person who makes a Goods declaration or in whose name such a declaration is made" (General Annex, definition E14). The Union Customs Code says the same thing at greater length — the declarant is "the person lodging a customs declaration … in his or her own name or the person in whose name such a declaration … is lodged" (Regulation (EU) No 952/2013, Article 5(15)).
• Both definitions turn on a distinction that decides the rest of this subject. Under direct representation the representative "shall act in the name of and on behalf of another person" (UCC Art. 18(1)) — so the declarant was you all along, even though somebody else assembled the data and pressed send. Under indirect representation the representative "shall act in his or her own name but on behalf of another person" — and there the declarant genuinely is the representative.
• So "should we self-file?" is not, on its face, a question about liability appearing out of nowhere. The useful version of the question is: which of the declarant's duties are you already carrying, which act are you about to perform yourself, and whose signature disappears from beside yours.
• One scope note before going further, because it governs everything below. The direct/indirect split is a Union Customs Code construct. The international standard protects something narrower — the choice between acting directly and designating a third party (RKC Standard 8.1) — and hands the rest to national legislation (Standards 8.2 and 3.6). Whether your administration recognises a direct/indirect distinction at all, and what each arrangement entails there, is national. Confirm with your customs authority.

Date check: what a cutover date does not close

• Date check: what a cutover date does not close — Two of the obligations on this page carry a period the Union Customs Code counts in years. Enter the event and its date to read those two back; the rest close on events, and this check will not turn an event into a date.
• The periods applied here are the Union Customs Code’s and the check uses no others. Outside the EU the retention length, the acceptable form of the records and the retrieval expectation are national; inside it the UCC period is a floor rather than a ceiling. Confirm both with your customs authority before acting on a result.
• Which event does your date mark? — Article 51(1) never runs from a decision or from a cutover announcement. It names three start points — acceptance of a declaration for release for free circulation or export; end-use goods ceasing to be subject to customs supervision; discharge of another customs procedure or the end of temporary storage — and the one that applies decides both results below. UCC Art. 51(1)
• Date of that event — The retention period is counted from the end of the year in which the event falls, so for the first result only the year carries weight. The exact day matters for the notification limit, which runs from the date the customs debt was incurred. UCC Art. 51(1); Art. 77(2); Art. 103(1)
• Have customs notified you that an entry must be corrected? — Where a control shows that an entry has to be corrected and the person concerned has been notified, the documents are kept for three years beyond the period that would otherwise apply. A running appeal or court proceedings extend it further, until those are terminated — which is an event, so the check does not date it. UCC Art. 51(2)
• Rules this check applies — These are the check's limits as much as its logic. It applies these rules and no others, and each carries the provision it rests on so you can read the provision rather than trust the check.
• You may choose to file directly — A protected choice, not a concession — and self-handled transactions may not be treated less favourably or be subject to more stringent requirements than represented ones — RKC General Annex Standards 8.1 and 8.3
• The conditions are national — National legislation sets who may act as declarant, and the liability of third parties to the Customs for duties and taxes and for any irregularities — RKC Standards 3.6 and 8.2
• Baseline entitlement — Any person having the right to dispose of the goods is entitled to act as declarant — RKC Standard 3.7
• Capability test — The filer must be able to provide all required information and to present the goods, or have them presented — UCC Art. 170(1)
• Establishment — In the EU the declarant must be established in the customs territory, with listed derogations for transit, temporary admission, occasional declarations accepted as justified, and adjacent-territory presenters — UCC Art. 170(2)–(3)
• Accuracy sits on the person lodging — Accuracy and completeness of the data, and authenticity and validity of supporting documents; a representative is bound in addition, not instead — UCC Art. 15(2); RKC Standard 3.8
• Documents at lodgement — Supporting documents must be in the declarant's possession and at the disposal of customs when the declaration is lodged — UCC Art. 163(1)
• Customs debt — The declarant is the debtor; under indirect representation the represented person is a debtor as well, and where several persons are liable for one debt they are jointly and severally liable — UCC Art. 77(3) (release for free circulation and temporary admission with partial relief; non-compliance debts name a different debtor set in Art. 79(3)); Art. 84
• When the debt is incurred — For release for free circulation and for temporary admission with partial relief the customs debt is incurred at the time of acceptance of the customs declaration. That is the only event on this page from which a notification limit can be counted, which is why the check computes one for that event and for no other — UCC Art. 77(2)
• Notification limit — No customs debt shall be notified to the debtor after the expiry of a period of three years from the date on which the customs debt was incurred; the period is longer where the debt arises from an act which at the time it was committed was liable to give rise to criminal court proceedings, and it is suspended while an appeal runs or while the customs authorities have communicated the grounds on which they intend to notify — UCC Art. 103(1)–(3)
• Retention — At least three years in the EU, kept by any means accessible by and acceptable to the customs authorities, and counted from the end of the year in which one of three events falls: the acceptance of the declarations for release for free circulation or export; the moment end-use goods cease to be subject to customs supervision; or the discharge of another customs procedure or the end of temporary storage. Where a control shows that an entry must be corrected and the person concerned has been notified, three years are added beyond that period; where an appeal or court proceedings are running, the documents are kept until those are terminated, whichever is the later. Periods elsewhere are national. — UCC Art. 51(1)–(2)
• Simplifications are personal — Regular use of a simplified declaration, and entry in the declarant's records, require an authorisation granted on application to a person — and each carries an unfinished supplementary declaration until that is lodged — UCC Arts. 166(2), 182(1), 167(1), 167(4)
• Competence is described as records control — A record of compliance and a satisfactory system for managing commercial records — not familiarity with forms. Note the placement: in the EU these are the criteria for AEO status and for the authorisations that carry simplifications, not a condition of lodging your own declaration, which is Art. 170(1) — RKC Transitional Standard 3.32; UCC Art. 39(b), (d)
• Control is by audit — Customs control systems include audit-based controls, and administrations evaluate traders' commercial systems where those systems affect customs operations — RKC Standards 6.6 and 6.10
• The electronic channel is defined by the authority — Electronic lodgement must be permitted — but as a Transitional Standard, so implementation timing and reservations vary by contracting party — while the customs administration specifies the conditions for applying information technology — RKC Transitional Standard 3.21; Standard 7.1
• Obligations opened before the switch do not close with it — Post-release control has no discharge event, a guarantee is released only when the debt is extinguished or can no longer arise, a transit movement ends and is discharged at two different moments, and a simplified declaration with its supplementary declaration is a single indivisible instrument — UCC Arts. 48, 98(1), 167(4), 215(2), 233(2), 51(1)
• This check applies only the rules quoted above, from the Revised Kyoto Convention General Annex and the Union Customs Code. It does not know your national thresholds, fees, licence conditions, guarantee requirements or software conformance rules, and it assumes none of them. It is not legal advice and it does not decide whether you may file. Confirm the result with your customs authority before acting on it.

Eleven questions the switch turns on, none of them a date

• Eleven questions the switch turns on, none of them a date — Work through these before naming a cutover date. Every one of them is answered somewhere on this page, and the last is answered only by the register of obligations that stay open.
• How are your declarations lodged today?
• Is the legal person who would be named as declarant established in the customs territory where you would file?
• Can you present the goods to customs, or have them presented, at the competent office?
• Can you supply every data element the procedure requires, from documents you hold?
• At the moment of lodging, will the supporting documents be in your possession and retrievable on request?
• Who decides commodity code, customs value and origin today?
• Can you retain declarations and their supporting documents for the full national period, in a form your authority accepts?
• Can you demonstrate control of your operations and flow of goods from your own commercial records?
• Do you have an accepted way to lodge electronically where you would file?
• Are you relying on a simplification today — a simplified declaration, or entry in the records?
• On the day you would switch, what would still be open under the current arrangement?

Are you allowed to file your own declarations?

• As an international standard, the choice is protected. RKC General Annex Standard 8.1: "Persons concerned shall have the choice of transacting business with the Customs either directly or by designating a third party to act on their behalf." Standard 8.3 closes the obvious loophole: transactions where the person concerned elects to do business on his own account "shall not be treated less favourably or be subject to more stringent requirements" than the same transactions handled by a third party.
• The conditions, however, are national by design. Standard 8.2: "National legislation shall set out the conditions under which a person may act for and on behalf of another person in dealing with the Customs and shall lay down the liability of third parties to the Customs for duties and taxes and for any irregularities." Standard 3.6: "National legislation shall specify the conditions under which a person is entitled to act as declarant." Standard 3.7 sets the baseline entitlement: "Any person having the right to dispose of the goods shall be entitled to act as declarant."
• The EU expresses the same gate as two capability tests plus an establishment rule. A declaration "may be lodged by any person who is able to provide all of the information which is required for the application of the provisions governing the customs procedure … That person shall also be able to present the goods in question or to have them presented to customs" (Art. 170(1)); and "the declarant shall be established in the customs territory of the Union" (Art. 170(2)), with derogations in Art. 170(3) for transit and temporary admission, occasional declarations accepted as justified, and persons established in an adjacent territory who present the goods at the border office.
• Read those tests literally, because they are the real gate — not the paperwork. Can you supply every required data element? Can you produce the goods? Everything beyond that — registration, guarantees, fees, competence proofs, software conformance — is decided where you file. This page does not guess any of it: confirm with your customs authority.

Is there such a thing as a "customs self-filing solution"?

• Not as a single product. The phrase compresses three layers that behave differently, and a product that touches one is not a substitute for a product that touches another.
• 1. The lodgement channel. How a declaration message actually reaches the administration. RKC Transitional Standard 3.21 requires that "the Customs shall permit the lodging of the Goods declaration by electronic means" — and the label matters: a Transitional Standard carries a longer implementation period and can be the subject of a reservation, so it binds less tightly than a Standard. Standard 7.1 states that "the Customs shall apply information technology to support Customs operations, where it is cost-effective and efficient for the Customs and for the trade. The Customs shall specify the conditions for its application." That last sentence is the whole answer: the channel is defined by the authority, and software either conforms to it or does not. This is a permission question, not a feature question.
• 2. The data layer. Assembling the declaration's data elements and the documents that support them, and holding both in a state you can defend. This layer is defined by published data-element catalogues rather than by any one authority's screen, which is where general-purpose software can help.
• 3. The control layer. Retention, retrieval and the ability to answer an audit years later. RKC Standard 6.6: "Customs control systems shall include audit-based controls." Standard 6.10: "The Customs shall evaluate traders' commercial systems where those systems have an impact on Customs operations to ensure compliance with Customs requirements."
• When you compare vendors, ask which of the three layers a product touches. Nothing prevents one product from touching all three, but a claim about layer 1 is a claim about an authority's rules, and should be checked against that authority rather than against a feature list.

What is customs document capture, and does self-filing need more of it or less?

• Document capture means turning invoices, transport documents, packing lists, licences and origin proofs into structured data elements. Two rules make it structural rather than clerical.
• First, possession at the moment of lodgement: "The supporting documents required for the application of the provisions governing the customs procedure … shall be in the declarant's possession and at the disposal of the customs authorities at the time when the customs declaration is lodged" (UCC Art. 163(1)). A document that exists somewhere in a mailbox is not in a state that satisfies that sentence.
• Second, the documents are your assertion, not the sender's. Lodging a declaration renders the person concerned responsible for "the authenticity, accuracy and validity of any document supporting the declaration" (Art. 15(2)(b)), and — where a representative lodges it — "that customs representative shall also be bound by the obligations set out in the first subparagraph". Also, not instead.
• Capture is worth building against a documented data-element catalogue rather than against the labels on a screen. The WCO Data Model is described by the WCO as "a compilation of clearly structured, harmonized, standardized, and reusable sets of data definitions and electronic messages", which "leverages standards established by international organizations such as … UN/CEFACT … and ISO to ensure global interoperability" and is mapped to the UN Trade Data Elements Directory; version 4 is the current iteration. In the EU, the common data requirements for declarations sit in Annex B to Commission Delegated Regulation (EU) 2015/2446 (adopted 28 July 2015 and amended repeatedly since). Field names taken from those catalogues survive a change of jurisdiction; field names copied off one country's form do not.
• Then the boundary that no capture tool crosses. Extraction reads what is printed. Classification, customs value and origin are determinations, not readings — and the declarant "shall be held responsible to the Customs for the accuracy of the particulars given in the Goods declaration and the payment of the duties and taxes" (RKC Standard 3.8). A code that appears nowhere in your documents is a proposal, not an extraction, and the output has to say which of the two it is.
• Self-filing therefore does not reduce how much capture you need. It removes the party who had been absorbing it.

What competence does a self-filer have to hold in-house?

• Both instruments describe competence in the same two terms, and neither of them is "knows the forms".
• RKC Transitional Standard 3.32 addresses "authorized persons who meet criteria specified by the Customs, including having an appropriate record of compliance with Customs requirements and a satisfactory system for managing their commercial records" — and then splits what follows into two registers. The Customs "shall provide for" release of the goods on the minimum information necessary to identify them, with the final declaration completed afterwards, and clearance at the declarant's premises or another authorised place. And then, "to the extent possible", other special procedures such as a single declaration covering a period, "use of the authorized persons' commercial records to self-assess their duty and tax liability", and lodgement "by means of an entry in the records of the authorized person to be supported subsequently by a supplementary Goods declaration". Note where the split falls: self-assessment from your own commercial records — the item a self-filer would most want — sits in the best-efforts half, not the mandatory one.
• The EU describes the same competence, in a different place and for a different purpose. It is not a condition of filing; that test is Art. 170(1), and it asks only whether you can supply the information and present the goods. Article 39 sets the criteria for authorised economic operator status and for the authorisations that carry simplifications: "the absence of any serious infringement or repeated infringements of customs legislation and taxation rules" (a); "the demonstration by the applicant of a high level of control of his or her operations and of the flow of goods, by means of a system of managing commercial and, where appropriate, transport records, which allows appropriate customs controls" (b); financial solvency (c); and, for the authorisation for customs simplifications, "practical standards of competence or professional qualifications" (d). An ordinary self-filer does not have to satisfy Art. 39 to lodge a declaration. But it describes what your records have to look like before any simplification becomes available to you — which is why it belongs in a competence discussion and not in an eligibility one.
• Translated into staffing, three roles have to exist somewhere inside the company before the first self-filed declaration, not after it: someone who owns the determinations (code, value, origin), someone who owns the choice of procedure and any authorisation it requires, and someone who owns the record. If you do not name them, they get named for you by whoever asks the questions later.

What record-keeping obligation does self-filing create?

• Strictly, none that did not already exist. In the EU the duty sits on "the person concerned", who "shall, for the purposes of customs controls, keep the documents and information referred to in Article 15(1) for at least three years, by any means accessible by and acceptable to the customs authorities" (Art. 51(1)). The clock is counted from the end of the year in which the declarations for release for free circulation or export are accepted; from the end of the year in which end-use goods cease to be subject to customs supervision; and from the end of the year in which another customs procedure has been discharged or temporary storage has ended. Where a control shows an entry must be corrected and the person has been notified, Art. 51(2) adds three years beyond that period; where an appeal or court proceedings are running, the documents are kept until those are terminated, whichever is the later.
• Retention lengths are national. Three years is the EU floor written into the UCC; other administrations set other periods, and this page does not transplant one into another — confirm the period, the acceptable form and the retrieval expectations with your customs authority.
• What self-filing changes is redundancy, not obligation. When a representative filed, a second archive existed. Afterwards, yours may be the only one — and, per Standard 6.10, your commercial system itself becomes something the administration may evaluate. That is the genuine "system requirement" of self-filing, and it outlasts any filing screen.

What is still open on the day you switch?

• A switch gets announced as a date. The obligations it is supposed to end are not all date-shaped: several were opened under the previous arrangement, in that arrangement's name, and they close on their own events.
• Retention runs from the end of a year, not from a decision (Art. 51(1)). Post-release control has no discharge event at all — customs "may verify the accuracy and completeness of the information given in a customs declaration … and the existence, authenticity, accuracy and validity of any supporting document … after having released them", and those controls "may be carried out at the premises of the holder of the goods or of the holder's representative, of any other person directly or indirectly involved in those operations in a business capacity or of any other person in possession of those documents and data for business purposes" (Art. 48). The exposure narrows only as the notification limit runs: "No customs debt shall be notified to the debtor after the expiry of a period of three years from the date on which the customs debt was incurred" (Art. 103(1)), extended for criminal acts and suspended in the cases listed in Art. 103(3).
• A guarantee is released "immediately when the customs debt or liability for other charges is extinguished or can no longer arise" (Art. 98(1)) — an event, not a date. A transit movement ends when the goods and the required information "are available at the customs office of destination" (Art. 233(2)) and is discharged when customs can establish, comparing the data at departure and at destination, that it ended correctly (Art. 215(2)); those are two different moments, and a movement can have ended physically while remaining undischarged. And a simplified declaration lodged before the switch is not a finished act at all: it and its supplementary declaration "shall be deemed to constitute a single, indivisible instrument" (Art. 167(4)).
• So the sentence "we moved to self-filing on 1 January" is, for a nameable list of obligations, false. The register below is that list.

Obligations that stay open after the cutover date

• Obligations that stay open after the cutover date — The unit of each row is a single open obligation, and the payload is what that obligation's ownership does when the filing arrangement changes underneath it. That is the register's whole thesis: a switch to self-filing is announced as a date, but the obligations it is supposed to end were opened under the previous arrangement and in that arrangement's name, and each closes on its own triggering event — a discharge, an extinguishment, a decision, the expiry of a notification limit. Some of those events are years out; some have no event at all. A consequence, not the justification: for several rows the obligation does not move to you and never will, because it was never yours to move. The columns are chosen so a reader can act on a row without reading the others — who opened it, who is still answering for it, what single event ends it, and what it prevents you from treating as finished in the meantime. Rows are not ordered by how long they run and durations stay inside the cells, because the register's claim is about closing conditions rather than about elapsed time. Every row carries the article or standard it rests on, so each is checkable against the instrument rather than against this page. Scope: the arrangements and the closing conditions below are the Union Customs Code's, and the basis column cites it. The international standard (RKC 8.1) protects only the choice between acting directly and designating a third party; whether your administration recognises a direct/indirect split, and which of these obligations it treats as surviving a change of filer, is national — confirm with your customs authority.

• UCC Art. 48; Art. 103(1)–(3) — Obligation still open: Answering a post-release control on declarations already released · Stays with: Reaches the holder of the goods, the holder's representative, "any other person directly or indirectly involved in those operations in a business capacity" and anyone holding the documents and data for business purposes · Opened under: Every declaration accepted and released before the switch, in whichever name it was lodged · What it blocks meanwhile: You cannot treat the former arrangement as closed for evidentiary purposes. A control can land at your premises or at the former representative's, and the answer has to come from records that neither party can reconstruct after the fact · Closes only when: Nothing discharges it. The exposure narrows only as the notification limit runs — no customs debt notified after three years from the date it was incurred, longer where the debt arises from a criminal act, and suspended while an appeal runs or while customs have communicated an intention to notify
• UCC Art. 77(3) (debts incurred on release for free circulation and temporary admission with partial relief; non-compliance debts name a different debtor set in Art. 79(3)); Art. 84; Art. 103(1) — Obligation still open: Being a debtor on consignments the representative declared in its own name · Stays with: Both parties, jointly and severally: "Where several persons are liable for payment of the amount of import or export duty corresponding to one customs debt, they shall be jointly and severally liable" · Opened under: Indirect representation only — the representative was declarant and the represented person was "also" a debtor · What it blocks meanwhile: There is no handover date for these consignments. The former representative keeps a live interest in how they are answered, and filing your own declarations from now on changes nothing about them · Closes only when: The customs debt on that consignment is extinguished, or can no longer be notified under the limitation in Art. 103
• UCC Art. 98(1)–(2) — Obligation still open: A guarantee standing behind pre-switch declarations and procedures · Stays with: The guarantee provider, until the authority releases it · Opened under: Whoever provided the guarantee for the declarations and procedures in force before the switch — the representative, where the representative arranged it · What it blocks meanwhile: The representative's guarantee cannot be wound down on your cutover date, and it does not cover what you file afterwards. Your own arrangement has to be in place for day one — these are two provisions running side by side, not a transfer · Closes only when: "The customs authorities shall release the guarantee immediately when the customs debt or liability for other charges is extinguished or can no longer arise." Partial extinguishment gives a corresponding partial release, at the request of the person concerned, unless the amount does not justify it
• UCC Art. 233(1)(a)–(c), 233(2); Art. 215(2)–(3) — Obligation still open: Bringing an open transit movement to its office of destination · Stays with: That holder: presentation of the goods intact and the required information at the office of destination within the prescribed time-limit, observance of the customs provisions relating to the procedure, and provision of a guarantee for any debt that may be incurred · Opened under: The holder of the Union transit procedure at the time of departure · What it blocks meanwhile: A movement can have physically ended and still be undischarged in the record. Until discharge, the guarantee behind it cannot be released and the situation of undischarged goods remains something the authorities must regularise · Closes only when: Two separate events. The obligation "shall be met and the transit procedure shall end when the goods placed under the procedure and the required information are available at the customs office of destination"; discharge follows only when customs can establish, comparing the data at departure and at destination, that the procedure ended correctly
• UCC Art. 215(1), (3)–(4); Art. 51(1) — Obligation still open: Discharging a special procedure the goods were placed under before the switch · Stays with: The holder of the procedure named at placement, not the party who files the next declaration · Opened under: The placement itself — inward or outward processing, temporary admission, end-use or storage — under the authorisation in force at the time · What it blocks meanwhile: For end-use goods the retention clock has not even started: it runs from the end of the year in which they cease to be subject to customs supervision, so the record obligation outlives the discharge by years · Closes only when: The goods or the processed products are placed under a subsequent customs procedure, taken out of the customs territory, destroyed with no waste remaining, or abandoned to the State — and within the time-limit set for discharge
• UCC Art. 167(1)–(4); Arts. 166(2), 182(1) — Obligation still open: Lodging a supplementary declaration still owed on a simplified one · Stays with: The declarant of the simplified declaration — the two are "deemed to constitute a single, indivisible instrument" taking effect on the date the simplified declaration was accepted, or the date the goods were entered in the records · Opened under: A simplified declaration under Art. 166, or an entry in the declarant's records under Art. 182, made before the switch on the authorisation then in force · What it blocks meanwhile: The earlier act is unfinished, not merely archived. For a simplified declaration under Art. 166 the supporting documents must also be in the declarant's possession and at the disposal of customs within a specific time-limit · Closes only when: The supplementary declaration is lodged within its time-limit at the competent office, or the obligation is waived — for goods placed under customs warehousing, in other specified cases, or where customs waive it on the conditions in Art. 167(3)
• UCC Art. 173(1)–(3) — Obligation still open: An amendment application lodged and not yet decided · Stays with: Whoever was declarant on that declaration. The right to apply follows that role, not your current arrangement · Opened under: The declaration being amended, and the person who was declarant on it · What it blocks meanwhile: Where the former representative was declarant, you are not the applicant on those declarations even after you begin filing your own — and the cut-offs run on the old declaration's clock · Closes only when: Customs decide. Amendment is refused once customs have informed the declarant of an intention to examine the goods, have established that the particulars are incorrect, or have released the goods; after release, a three-year route from the date of acceptance remains
• UCC Art. 121(1)(a)–(c); Art. 103(3)–(4) — Obligation still open: A repayment or remission application still pending · Stays with: The applicant named on it · Opened under: The application as filed, in the name of whoever filed it · What it blocks meanwhile: Where a customs debt is reinstated after such an application, the notification limit is suspended from the date the application was filed until the decision is taken — so neither side can close the file while it is open · Closes only when: The decision is given. The filing windows themselves are fixed: three years from notification of the customs debt for overcharge, error by the competent authorities or equity; one year for defective goods or goods not complying with the contract; and the invalidation period where a declaration is invalidated
• UCC Art. 51(1)–(2); RKC Standards 6.6, 6.10 — Obligation still open: Retaining the declarations already lodged and their supporting documents · Stays with: "The person concerned" — the importer or exporter. A representative's archive is a convenience that was never a transfer of the duty · Opened under: Each declaration accepted before the switch, whoever assembled it · What it blocks meanwhile: The relationship cannot be treated as closed for archive purposes, and retrieval has to survive the handover: the obligation is to keep the documents "by any means accessible by and acceptable to the customs authorities", which is tested when someone asks · Closes only when: The applicable national period expires. In the EU that is at least three years, counted from the end of the year of acceptance for release for free circulation or export, from the end of the year end-use goods cease to be under customs supervision, or from the end of the year another procedure was discharged or temporary storage ended — plus three further years where a control shows an entry must be corrected and you have been notified, and until any appeal or court proceedings are terminated

When does a representative still cost less than filing yourself?

• When does a representative still cost less than filing yourself? — No honest figure answers this, because the comparison is not between a fee and a licence — it is between a fee and a set of obligations that behave differently at different volumes. The variables that actually move it:
• Variety against volume — A hundred declarations across three commodity codes and one procedure is a different exercise from twenty declarations across forty codes; the work sits in determinations, not in submissions.
• Procedures beyond release for free circulation — Transit, temporary admission, inward and outward processing and end-use each add conditions, and end-use even changes when your retention clock starts (Art. 51(1)).
• Establishment — If the declarant would not be established where you file, self-filing is closed for most procedures and indirect representation is the route that exists (Arts. 170(2)–(3), 18(2)).
• Authorisations — "The regular use of a simplified declaration … shall be subject to an authorisation from the customs authorities" (Art. 166(2)), and entry in the declarant's records is authorised "upon application" to a person (Art. 182(1)). An authorisation is granted to somebody; the one a representative holds is theirs.
• Exception handling — Amendment is a declarant's right, exercised on application and cut off once customs announce an examination, establish that particulars are incorrect, or release the goods (Art. 173(1)–(2)), with a three-year post-release route in Art. 173(3). Whoever is declarant is the party who has to notice in time.
• The carryover itself — Everything in the register above continues to consume attention after the switch, and some of it continues to consume the former representative's attention too.

• Two standards are worth holding onto while doing this arithmetic. A designated third party "shall have the same rights as the person who designated him in those matters related to transacting business with the Customs" (RKC 8.4) — an equivalence scoped to customs dealings, not a general one. And self-handled transactions may not be treated less favourably (8.3). Neither channel is a status upgrade over the other. Because the capacity in which someone acts is stated when dealing with customs (Art. 19(1)), the choice does not have to be all-or-nothing across your whole flow.

What does Logistivo do here, and where does it stop?

• What does Logistivo do here, and where does it stop? — Logistivo is logistics software built for Türkiye and the EU. On this subject it does a specific, bounded set of things:
• customs-consultant and customer accounts that see the shipments they are attached to, with the documents and status the parties share;
• AI field extraction from document images and PDFs, run as tracked background jobs so a long extraction has a state you can watch rather than a spinner, with the classification result stored against the file;
• a cross-document consistency analysis over an uploaded document set, which reports disagreements between documents;
• commodity-code lookup against the Turkish tariff nomenclature — 23,581 codes in the 2026 schedule, 17,619 of them leaf codes carrying a statutory duty rate — with in-force anti-dumping and safeguard measures for the trade directions the customs module covers, taken from published official tariff data;
• assembly of export document sets — proforma invoice, commercial invoice, packing list, certificate-of-origin application, movement-certificate application — noting that an application is what the software produces; the instrument itself is issued by the competent chamber or authority;
• a free, single-use customs document reader on this site, which reads one commercial document and returns eighteen declaration data elements drawn from the WCO Data Model and the Annex B categories — consignor and consignee with their countries, invoice number and date, Incoterm and place, currency and total, description of goods, commodity code, country of origin, gross and net mass, package count and kind, transport document reference — together with the elements it could not find and the ones it could not read.

• And the boundary, stated plainly because a page about self-filing is exactly where vagueness would be expensive. Logistivo does not lodge declarations; does not connect to any customs administration's system; does not decide classification, customs value or origin for you; and gives no output legal validity. The document reader in particular does not classify goods and returns a commodity code only when one is printed on the document — where the description is all there is, the code goes on the missing list rather than being derived. The separate tariff tool does propose candidate codes from a goods description, and it labels them as candidates with a confidence score and resolves them against the published nomenclature so you can read the official description before accepting one. Either way the determination is yours to make and to assert. Whether a given retention arrangement or file format satisfies your administration is for that administration to say.

Frequently asked questions

Is customs self-filing allowed everywhere?

The choice is an international standard: RKC General Annex Standard 8.1 gives persons concerned "the choice of transacting business with the Customs either directly or by designating a third party to act on their behalf", and Standard 8.3 says self-handled transactions may not be treated less favourably or be subject to more stringent requirements. But Standards 3.6 and 8.2 hand the conditions to national legislation — who may act as declarant, and the liability of third parties to the Customs for duties and taxes and for any irregularities. So the right exists in principle while the conditions, registrations and system access are decided where you file. Confirm with your customs authority.

Does self-filing make me more liable than using a broker?

Not in the way it is usually described in sales material. Under direct representation you were already the declarant, and the representative was bound "in addition" to you, not instead (UCC Art. 15(2)). Self-filing removes the party bound alongside you; it does not raise the standard applied to you. The one real change is under indirect representation, where the representative is the declarant and both of you are debtors for the customs debt (Art. 77(3), for debts incurred on release for free circulation and temporary admission with partial relief) and are jointly and severally liable for it (Art. 84). File yourself and, on new consignments, that second debtor is gone. On consignments already declared in the representative's own name, nothing changes at all.

Do I need special software to file my own declarations?

You need a channel your administration accepts, which is a separate question from software features. RKC Transitional Standard 3.21 requires customs to permit electronic lodgement — and being a Transitional Standard rather than a Standard, its implementation timing and any reservations vary by contracting party — while Standard 7.1 states that "the Customs shall specify the conditions for its application". Ask your authority which channels are open to a filer who is not a representative and what conformance they require. Software can assemble the data and hold the records regardless; whether it may transmit is the authority's call.

What is "customs brokerage document capture", and do I still need it if I file myself?

It is the step that turns invoices, transport documents, packing lists and origin proofs into the data elements a declaration requires. Self-filing increases rather than reduces your exposure to it: supporting documents must be in the declarant's possession and at the disposal of customs at the moment of lodgement (UCC Art. 163(1)), and their authenticity, accuracy and validity are the responsibility of the person lodging (Art. 15(2)(b)). Filing yourself does not remove the work — it removes the party who had been absorbing it.

Can AI extraction choose the commodity code for my declaration?

Extraction reads what is printed on a document; classification, customs value and origin are determinations that the declarant is "held responsible to the Customs for" (RKC Standard 3.8). A commodity code is a defensible output only when the tool tells you where it came from. Logistivo's document reader returns a code only when one is printed on the document, and lists it as missing otherwise. A separate tariff tool does propose candidate HS and GTİP codes from the goods description — it returns them labelled as candidates with a confidence score and resolves them against the published nomenclature, so you can read the official description of the code before accepting it. Either way the determination stays yours to make and to assert.

How long do I have to keep the documents once I file myself?

The obligation is not created by self-filing — it already sits on "the person concerned". In the EU that is at least three years by any means accessible by and acceptable to the customs authorities, counted from the end of the year the declaration was accepted, with different start points for end-use goods and for other procedures, plus three further years where a control shows an entry must be corrected and you have been notified, and until any appeal or court proceedings are terminated (UCC Art. 51). Retention periods outside the EU are national — confirm yours. What changes with self-filing is that your archive may be the only copy.

Can I self-file some shipments and keep a representative for others?

Nothing in the framework makes the choice a permanent status. A representative is appointed by a person (UCC Art. 18(1)) and the capacity in which someone acts is stated when dealing with customs (Art. 19(1)). One available shape is to file the repetitive, stable lines in-house and leave exceptional procedures with a representative. Three cautions: any simplification you use through a representative runs on their authorisation and does not follow you (Arts. 166(2), 182(1)); a mixed model means two record trails that both have to satisfy the same retention rule; and consignments the representative declares in its own name keep both of you as debtors until those debts are extinguished (Arts. 77(3), 84).

When can we stop working with our customs broker?

Not on the date you file your first declaration yourself. Several obligations opened under the previous arrangement close on their own events. Retention runs for at least three years in the EU from the end of the year of acceptance (Art. 51(1)). A guarantee is released only when the debt "is extinguished or can no longer arise" (Art. 98(1)). An open transit movement ends at the office of destination and is discharged separately, once customs compare the departure and destination data (Arts. 233(2), 215(2)). A simplified declaration and its supplementary declaration are "a single, indivisible instrument" (Art. 167(4)), so an unlodged supplementary declaration leaves the earlier act unfinished. Post-release control can reach the representative's premises as well as yours (Art. 48), narrowing only as the three-year notification limit runs (Art. 103(1)). And where the representative filed in its own name, both of you remain debtors on those consignments (Arts. 77(3), 84).
