The knowledge limit in that paragraph caps the broker's liability and does nothing for the importer's; where the loss finally lands is settled by the power of attorney and the mandate rules of the Turkish Code of Obligations, not by the customs file.
If a Turkish customs broker files an import declaration under indirect representation and the declaration turns out to be wrong, the customs administration can pursue the importer for the full amount. Article 181(2) of Customs Law No. 4458 makes the declarant the debtor of the import duty and adds, in indirect representation, the person on whose account the declaration was made; Article 192 makes multiple debtors of the same duty jointly and severally liable. The broker’s own liability is narrower than the importer’s, and the question of who ultimately bears the loss is not decided by the customs file at all.
That asymmetry is the practical point of this note. It matters to importers, who often assume that instructing a broker transfers the risk, and it matters to brokerage companies, whose exposure runs on a different provision from their client’s. What follows sets out how the Law allocates the liability, where the private-law recourse claim lives, and what the documents signed at the start of the relationship should already say. It sits alongside our guides to customs duty in Türkiye and to importing goods into Türkiye.
Who Files, and In Whose Name
Article 5 begins from a permission: any person may appoint a representative for its business before the customs administrations. Representation is either direct or indirect. In direct representation the representative acts in another’s name and for that other’s account. In indirect representation it acts in its own name, but for another’s account. The representative must declare that it is acting on behalf of the represented person, state whether the representation is direct or indirect, and produce its authority document to customs.
The paragraph that follows is easy to skip and decides files. A person who does not declare that it acts in another’s name or for another’s account, or who declares that it does so without holding authority, is deemed to act in its own name and for its own account. The form of representation is therefore not a private arrangement between importer and broker; it is a declared status, and an undeclared one collapses onto the person who signed.
Article 225(1) then allocates the two routes. Activities relating to placing goods under a customs-approved treatment or use are pursued either by the owners and those acting in their name by direct representation, or by customs brokers by indirect representation. Direct representation by a natural person is confined to goods of non-commercial quantity and nature and to private vehicles, on a valid power of attorney. For corporate importers the significant sentence is in Article 225(2): personnel authorised to represent a private-law legal person may pursue all customs formalities by direct representation, provided they satisfy the conditions in Article 227(1) other than subparagraphs (g) and (h) — that is, the eligibility conditions without the traineeship and examination requirements. An importer with sufficient internal capability can therefore file in its own name; most do not, and the choice has consequences.
There is a staffing limit on the same choice. Under Article 562 of the Customs Regulation a customs broker employed within a legal person other than a brokerage company may pursue only the formalities of goods belonging to the company it works for — so an in-house broker cannot cover the declarations of other companies in the same group.
Article 561(3) of the Customs Regulation adds the formal requirement: indirect representation before customs is available to brokers holding a notarised power of attorney given by the owner of the goods, with the qualification that powers of attorney issued by public institutions and organisations do not need notarisation. Article 561(5) makes production of that document a condition of acting at all.
| Direct representation | Indirect representation | |
|---|---|---|
| Who may act | The owner and those acting in its name; for companies, authorised personnel meeting Art. 227(1) other than (g) and (h) | Customs brokers (Art. 225(1)); postal administration and express carriers for consignments within the limits set under Art. 225(1) |
| Whose name is on the declaration | The importer's | The broker's own name, for the importer's account |
| Debtor of the import duty | The importer as declarant (Art. 3(17), Art. 181(2)) | The broker as declarant and the importer as the person on whose account the declaration was made (Art. 181(2)) |
| Between them | Single debtor | Joint and several liability for the same duties (Art. 192) |
| Document required | Authority document; for company personnel, SGK payroll, trade registry gazette and registry certificate (Reg. Art. 561(4)(a)) | Notarised power of attorney with the minimum content in Reg. Art. 561(3) |
The Line Article 181(2) Draws — and Who It Protects
Article 3(17) defines the declarant as the person who makes the declaration in its own name or the person in whose name the declaration is made. Article 181(2) builds on that: “the debtor is the declarant. In the case of indirect representation, the person on whose account the customs declaration is made is also a debtor.” Two debtors, one debt, and Article 192 supplies the rest — where more than one debtor is liable for the same customs duties, they are liable jointly and severally.
The third sentence of the same paragraph is the one both sides quote, for opposite purposes: “In indirect representation, the representative’s liability is limited to cases where it knew that the data used in the declaration were incorrect or, in the ordinary course of its profession, ought to have known.” Article 181(3) extends liability in the other direction, to persons who supplied the data used in the declaration and knew or ought to have known they were wrong — which can reach a supplier, a group affiliate or a consultant who never appears on the declaration.
Read together, these provisions produce a result importers regularly misread. The knowledge test is a ceiling on the representative’s liability, not a general defence attached to the declaration. Nothing in Article 181 conditions the liability of the person on whose account the declaration was made on that person’s knowledge. An importer who genuinely did not know the tariff heading was wrong is still a debtor; the broker, in the same file, may not be. Article 563(1) of the Customs Regulation confirms the direction of travel from the broker’s side: brokers are responsible for the accuracy of the information stated on the declarations they sign and of the documents annexed to them, and for compliance with all the obligations of the relevant regime — but expressly “subject to Article 181(2) of the Law”.
How long this shared liability can surface belongs in the same section. Article 197(2) requires notification of customs duties found on inspection not to have been collected, or to have been collected short, to be made within three years from the date the customs obligation arose. The sentence that follows does not leave that period alone: the bringing of an action in connection with the event giving rise to the customs obligation suspends the limitation period, and Article 197(4) displaces the three years only where two conditions are met together: the claim must relate to an act requiring a penalty, and a criminal case must actually have been brought for that act, whose own limitation period is the longer one. Only then are the duties pursued and collected within the prosecution and penalty limitation periods of the Turkish Criminal Code No. 5237; without that filing the three years stands. The practical consequence is that an import file can come back years after the goods were released, when the importer’s own personnel have long since changed — which is why keeping the correspondence showing what a classification or valuation decision rested on is too important to leave to the broker’s retention duty under Article 230.
The Broker’s Own Layers of Exposure
For a brokerage company the picture has additional layers that the importer’s file does not show.
Article 229(2) deals with brokerage practised through a legal entity. Where those who have signed the customs declaration, or the documents accepted in its place, knew or ought to have known of the situation causing the revenue loss, they are jointly and severally liable towards the customs administration together with the legal entity to which they belong. The sentence that follows extends the same joint liability, without prejudice to the broker’s personal criminal liability, to the legal entity alongside the person who carried out the transaction, in respect of both the duties collected and the fines imposed by the customs administration. Article 226(4) allocates internally in the other direction: the financial liability arising from the acts of assistant brokers and trainees belongs to the broker they work for.
There is also a professional layer with no equivalent on the importer’s side. Provisional Article 6(2) of Law No. 4458 sets out the disciplinary sanctions for members of the profession — warning, reprimand, temporary suspension from professional activity for not less than six months and not more than one year, and removal from the profession. The sub-paragraph that matters to the knowledge question comes shortly after: where central inspectors report that a false declaration was made on the basis of forged documents without the broker’s knowledge, but that the true position could have been discovered by investigation, the broker receives a reprimand for the first occurrence and a temporary suspension if it recurs. Not knowing, in other words, is assessed against what an inquiry would have revealed.
Two ancillary obligations belong in the same picture because they generate the evidence the recourse claim later needs. Article 230 requires brokers to keep, for five years, their commercial and statutory books, their powers of attorney and contracts, their correspondence, and their invoices, receipts and expense records, and to produce them to inspectors on written request. Article 563(7) of the Customs Regulation, added in 2024, prohibits disclosure of information and trade secrets learned from clients even after the professional activity has ended, with the qualification that the prohibition does not apply in the event of any judicial or administrative examination or investigation. Article 563(8) and (9) require data-security measures and, where declaration software is obtained from a third party, a written contract expressly covering data security and confidentiality — a broker that has not put that contract in place may not provide indirect representation services until it does.
The Question the Customs Decision Does Not Answer
An additional assessment tells the parties who must pay the State. It says nothing about which of them should end up out of pocket. That is a matter for the contractual relationship between them and for the Turkish Code of Obligations No. 6098.
The relationship is a mandate. Article 502 defines it as the mandatary undertaking to carry out a task or transaction for the principal, and provides that the mandate rules apply, so far as compatible, to service contracts not otherwise regulated in the Code. Article 505 obliges the mandatary to comply with the principal’s express instructions and provides that a mandatary who departs from them has not performed the mandate unless it makes good the resulting loss — even if the task was completed. Article 506 requires the mandatary to act with loyalty and care in the principal’s legitimate interest, and sets the standard by reference to the conduct expected of a prudent mandatary undertaking similar work in the same field. Article 112 supplies the remedy: where an obligation is not performed, or not performed properly, the debtor must compensate the loss unless it proves that no fault whatever can be attributed to it.
The traffic runs in both directions, which is why brokerage companies read the same articles. Article 510 requires the principal to reimburse the expenses and advances made by the mandatary for the proper performance of the mandate together with interest, and to release it from the obligations it has undertaken — the provision behind a broker’s claim for duties it has paid at the border. Its second paragraph allows the mandatary to claim compensation for loss suffered by reason of performing the mandate, but permits the principal to escape by proving absence of fault. Article 509 is the private-law mirror of indirect representation: claims against third parties arising from work the mandatary carried out in its own name for the principal’s account pass automatically to the principal once the principal has performed all its obligations to the mandatary.
Where both parties have been held liable for the same loss, Article 61 applies the joint-liability rules and Article 62 governs the internal relationship: apportionment takes account of all the circumstances, in particular the gravity of the fault attributable to each and the intensity of the danger each created, and a person who pays more than its share has a right of recourse against the other joint obligors for the excess, being subrogated to the injured party’s rights. Article 73 sets the recourse limitation period at two years from full payment and knowledge of the co-obligor, and ten years from full payment in any event, with time running only from when notification to the co-obligors could have been given in good faith where that notification was not made. Article 147(5) subjects claims arising from a mandate to a five-year period against the general ten years in Article 146, and Article 148 provides that these periods cannot be altered by agreement.
One drafting limit follows from Article 115. An advance agreement that the debtor will not be liable for its gross fault is void; and where a service, profession or trade requiring expertise may be carried on only under a permission granted by law or by the competent authorities — Article 228(3) of Law No. 4458 allows customs brokers to practise only once the customs brokerage permit document has been issued to them — an advance exclusion even of slight fault is void. Article 116 applies the same permission test to clauses excluding liability for the acts of auxiliaries. Allocating tasks and defining deliverables works; a blanket disclaimer does not.
What the Documents Should Already Say
The place to fix this is the notarised power of attorney and the service agreement behind it, before any consignment moves. Article 561(3) of the Customs Regulation lists the minimum content, and one item is an open door: the parties’ mutual responsibilities and obligations that they need to determine in addition to those set out in the Law. That is an instruction to allocate, not to recite.
In practice the allocation turns on who owns each input to the declaration. Who determines the tariff heading, and on what technical documentation. Who provides the valuation data, including any royalty or licence fee that may need to be added to the customs value. Who holds the originals of origin documents and for how long, measured against the five-year retention duty in Article 230. What the broker must do on receiving an instruction it considers wrong, given the Article 505 rule on departing from instructions. How each party notifies the other of a customs notification, so that the fifteen-day periods in Articles 242 and 244 are not lost by an envelope sitting on the wrong desk. And whether a settlement application by one debtor binds the other — the Law lets each act separately, so silence in the contract means each may act alone; that last point is taken up separately in our note on objecting to and settling customs administrative fines.
None of this is exotic drafting. It is the ordinary content of a well-made services agreement, applied to a relationship in which customs law has already decided that two parties will answer to the State for the same figure. The allocation of that figure between them is the one part the parties still control, and it is far cheaper to settle in the power of attorney than in the recourse action that follows an assessment served three years after the goods were released.
