Import surveillance in Türkiye is a trade policy measure, not a tax. It rests on the Decree on the Application of Surveillance in Imports numbered 2004/7304, published in the Official Gazette of 29 May 2004 No. 25476, and it works by requiring a surveillance document for goods whose unit value falls below a figure set in a product-specific Communiqué. The commercial consequence is what brings importers to a lawyer: because a Communiqué catches only goods declared below the stated figure, declaring at or above it takes the consignment outside the measure — and every lira of that uplift is taxed. The legal position on recovering the difference is materially different from the position before July 2021, and one of the interest provisions that governed repayment ceased to apply on 30 September 2026.
This guide sets out where the threshold value actually comes from, what Law No. 4458 says about customs value, and which routes of challenge remain open.
The Chain of Instruments
Surveillance is built in four layers, and confusing them is the most common source of bad advice.
At the top sits the enabling legislation. The Decree was made by the Council of Ministers on 10 May 2004 on the basis of Article 1 of Law No. 1567, Article 2 of Law No. 474, Article 2 of Law No. 3283, Article 55 of Law No. 4458 and the provisions of Law No. 2976 on the Regulation of Foreign Trade.
Below the Decree sits the Regulation on the Application of Surveillance in Imports, published in the Official Gazette of 8 June 2004 No. 25486. Under Article 3, the decision to apply surveillance is taken by the Ministry on application or of its own motion, and the assessment looks at the development of imports, the conditions of importation and the effect of imports on domestic producers. The measure may be prospective, operating through the issue of a surveillance document, or retrospective, in which case imports are simply registered. Where prospective surveillance applies, the surveillance document is required in addition to the documents customs legislation demands.
Article 4 of the Regulation sets the terms on which the document is issued: within ten working days of a properly made application reaching the Directorate General, for the full quantity requested, and without any fee. The sentence that follows is the qualification — the document is not issued where the declaration is found to be untrue or the information and documents submitted are inconsistent. Documents are non-transferable, and the original of an expired document must be returned before a new one is issued. A tolerance operates at the border: where the value or quantity established and accepted by customs exceeds that recorded in the document by less than five per cent, inclusive, importation is not prevented, and the Directorate General may set a different rate up to ten per cent.
Neither the Decree nor the Regulation mentions a price. That is the fourth layer.
Where the Threshold Value Actually Comes From
The number lives in a Communiqué on the Application of Surveillance in Imports, issued by the Ministry of Trade for a specific tariff line. Because these are published constantly and superseded just as fast, the only reliable figure is the one in force for that GTİP on the day the declaration is registered. A dated example makes the structure concrete.
The Communiqué numbered 2025/1, published in the Official Gazette of 11 January 2025 No. 32779, applies prospective surveillance to goods under two tariff lines — but its first article limits the scope to those having unit values below the customs value shown against them. The table names 1.5 US dollars per gross kilogram for one line and 1.75 for the other. Article 2(1) then provides that those goods may be imported only with a surveillance document issued by the Directorate General of Imports, and that the document is required by customs at the registration of the declaration. Applications go through the Single Window System with an electronic signature; the document is issued electronically, notified to the e-mail address on the application form, and its twenty-three-digit number and date are declared in box 44 of the declaration. Article 7(1) gives the document a validity of six months.
Article 7(2) is the sentence that decides most disputes:
The surveillance document does not prevent the application of the provisions of Law No. 4458 on the customs value of goods. The value stated in article 1 does not constitute a basis for the application of the provisions of Law No. 4458 on the customs value of goods.
The instrument that sets the threshold says, in terms, that the threshold is not a customs value.
Two Roads at the Border
Faced with a consignment invoiced below the threshold, an importer has two lawful routes and no third one.
| Apply for the surveillance document | Declare at or above the threshold | |
|---|---|---|
| Legal footing | Article 2(1) of the Communiqué; Articles 3 and 4 of the 2004 Regulation. | The goods fall outside the Communiqué's scope as drafted in its first article, so no document is required. |
| Timing | Ten working days from a properly made application; the document is valid six months under the 2025/1 Communiqué. | Immediate, at registration of the declaration. |
| Direct cost | None — the Regulation requires the document to be issued without any fee. | Customs duty, any additional customs duty and VAT, all computed on the higher figure. |
| Risk | Not issued where the declaration is found untrue or the file inconsistent; cancelled under Article 7 of the Decree for forgery, false documents, transfer to a third party or breach of undertakings, with no further document while the measure is in force. | The declared value departs from the transaction value, which Articles 24 and 27(3) of Law No. 4458 make the starting point and the closed list respectively. |
| Recovery of the difference | Not applicable. | Article 211(1) of Law No. 4458 refuses refund claims where the value of goods subject to trade policy measures was raised by the person's own declaration. |
The cost of the second road is larger than the difference in duty alone. Article 21(a) of Law No. 3065 on Value Added Tax fixes the import VAT base as the value on which customs duty is assessed, and Article 21(b) adds every tax, duty, charge and share paid on importation. So an uplift in customs value raises the ordinary duty, raises any additional financial obligation or additional customs duty computed on value, and then raises VAT on the enlarged total. The same cascade is what makes ordinary customs duty in Türkiye and the broader mechanics of importing goods into Türkiye worth getting right before a container moves rather than after.
There is a second pressure behind the uplift, and it is worth naming. Article 234(1)(b) of Law No. 4458 provides that where the declared value of goods liable to duty on value is found deficient against the value determined under Articles 23 to 31, a fine of three times the duty difference is imposed on top of the duty itself. Article 234(3) reduces those fines to ten per cent where the declarant reports the discrepancy before customs detects it. Defensive over-declaration is, in other words, a rational response to a penalty structure — which is precisely why the valuation rules matter.
What Law No. 4458 Says About Customs Value
The valuation rules run in a fixed order and they are not permissive.
Article 24(1) makes the customs value of imported goods the transaction value — the price actually paid or payable in a sale for export to Türkiye, adjusted under Articles 27 and 28. The paragraph then attaches four conditions to using that price, of which the practically important ones are that there be no restriction on the buyer’s disposal or use beyond the categories listed, and no relationship between buyer and seller that affects the price. Article 24(2)(a) makes the point that a relationship is not, by itself, a sufficient reason to reject the transaction value; where the administration considers the price affected, it must say so in writing and the declarant’s right of reply is reserved.
Where the transaction value cannot be used, Article 25 supplies four successive methods — the transaction value of identical goods, of similar goods, the deductive method and the computed method — and provides that no lower subparagraph applies while a higher one can. Only then does Article 26 open the fall-back method, which must follow the principles of the WTO Customs Valuation Agreement and GATT Article VII on the basis of data available in Türkiye.
Article 26(2) then lists what may not be taken as a basis, and three entries in that list decide the surveillance question:
| Article 26(2) of Law No. 4458 — excluded bases | Why it bites here |
|---|---|
| (b) A system providing for the customs administration to accept the higher of two alternative values | Choosing between the invoice and a published threshold, and taking the higher, is that system. |
| (f) Minimum customs values | A published figure below which goods may not clear without a document functions as a floor. |
| (g) Arbitrary or fictitious values | A figure set to monitor import trends is not derived from the transaction. |
Article 27 completes the picture from the other side. Its second paragraph requires additions to rest on objective and quantifiable data; its third states that no addition may be made to the price actually paid or payable other than those the article provides for. Declaring the gap between invoice and threshold as an “overseas expense” does not fit any heading in Article 27(1).
Read together, these provisions mean that a figure fixed by the administration to monitor imports is not a customs value determined under Law No. 4458: even the fall-back method of Article 26 may not rest on minimum customs values or on arbitrary or fictitious values. That is the same analytical starting point that applies to the exporter-specific measures examined in anti-dumping duties in Türkiye, where the duty is calibrated to a margin rather than to a published price.
The Refund Route, and What Changed in 2021
Article 211(1) of Law No. 4458 opens with the general rule: duties paid when they were not legally payable are repaid, and duties assessed when they should not have been are remitted. Article 211(2) sets the period at three years from notification to the person liable, extendable for force majeure or unforeseeable circumstances.
The sentence that follows the general rule is where the file is usually decided. Refund and remission claims are not accepted where the duties were paid or assessed as a result of a deliberate falsification by the person concerned — or, by wording inserted by Law No. 7333 of 18 July 2021, as a result of the customs value of goods subject to trade policy measures being raised by the person liable’s own declaration.
Two links complete that chain. Article 3(1)(n) of the Customs Regulation defines trade policy measures as non-tariff measures such as surveillance, safeguard measures, quantitative restrictions and import or export prohibitions. And Article 205(2) of the same Regulation fixes the registration date of the free-circulation declaration as the reference date for applying those measures. So a declaration registered after the 2021 amendment, on goods under a surveillance Communiqué, uplifted by the importer, sits squarely inside the exclusion.
This matters more than it first appears, because before July 2021 Article 211 excluded only deliberate falsification. A refund argument built on that earlier wording does not carry over to a declaration registered after the amendment, so the registration date of each declaration has to be fixed before a refund application is framed.
One further change has now taken effect. Article 216(1) of Law No. 4458 governed interest on repayment: where the excess collection originates from the person liable, interest runs from the date of the refund application; in other cases, from the date of collection, in each case to the date the refund decision is notified, at the statutory rate since a 2023 amendment replaced the deferral-interest reference. That paragraph was annulled by the Constitutional Court, in a decision published in the Official Gazette of 31 December 2025, with effect nine months later, on 30 September 2026. Since that date the Law contains no rule on interest running from collection or from the refund application. What remains is Article 216(2): where the administration does not implement the refund decision within four months of its notification, interest at the statutory rate is paid on request for the period from notification to payment. Whether new legislation will fill the gap left by the annulment is not yet known.
Objection, Reservation and the Route into Court
The procedural route for customs taxes is not the general tax route, and the confusion is written into the statute book for a reason. Article 2 of the Tax Procedure Law No. 213 states that taxes and duties collected by customs administrations are not subject to that Law, and directs that Article 242 of Law No. 4458 applies instead. So the familiar Article 378 rule — that taxpayers cannot sue on the bases they themselves declared — does not govern here, and neither does the machinery built around it. A reservation noted on a customs declaration is a practical signal of disagreement; the legal act that preserves the position is the objection.
Article 242 sets the framework. An objection to duties, penalties or administrative decisions notified to the person liable must be made within fifteen days of notification, by petition to the higher authority or, where there is none, to the same authority. The administration decides within thirty days and notifies the decision. A petition filed with the wrong authority within the period is still treated as timely and forwarded internally. Against a rejection, the administrative judiciary at the place where the act was done can be approached.
Fixing the start of the fifteen days is the step most often got wrong. Article 197(3) provides that where the amount of duty shown by the person liable in the declaration equals the amount calculated by customs, release of the goods takes the place of notification. On a self-declared uplift there is no separate assessment notice waiting in the post; the clock starts when the goods come out.
Collection does not pause while this happens. Article 27(1) of Law No. 2577 provides that bringing an action does not stay execution of the contested act. Article 27(4) creates the tax-case exception — bringing an action stays collection of the contested portion of assessed taxes, similar financial obligations and their surcharges and penalties — but the next sentence removes that automatic effect for actions arising from returns filed with a reservation and from collection procedures themselves. For those, a stay must be applied for and can be granted only where the act is manifestly unlawful and its application would cause damage difficult or impossible to repair, both together, normally after the administration’s defence.
One route should not be confused with another. Settlement under Article 244 is available for subsequent assessments and penalty decisions issued by customs, on application within fifteen days, and making that application suspends the objection and litigation periods. It is not a route for an importer that simply paid on its own declaration, and Article 244(4) closes off any action on what has been settled.
| Route | Provision | Period | When it is the right track |
|---|---|---|---|
| Objection | Art. 242(1), Law No. 4458 | 15 days from notification; decision within 30 days | Against duties, penalties and administrative decisions notified to you — including where release of the goods stood as notification under Art. 197(3). |
| Refund / remission | Art. 211, Law No. 4458 | 3 years from notification | Duties not legally payable — subject to the exclusion for values raised by your own declaration on goods under a trade policy measure. |
| Settlement | Art. 244, Law No. 4458 | 15 days from notification; periods suspended while pending | A subsequent assessment or penalty decision has been issued, and the act is unconnected with the smuggling offences in Law No. 5607. |
| Administrative judiciary | Art. 242(4), Law No. 4458 | After rejection of the objection | Every contested route ends here; collection is not automatically stayed where the claim arises from a return filed with a reservation. |
Where the Work Actually Is
Surveillance files are won or lost before the declaration is registered, not after. The tariff classification decides whether a Communiqué applies at all; the valuation file decides whether the transaction value stands under Article 24; and the choice between applying for a document and uplifting the declaration decides which of the routes above will still be open months later. Where inputs are imported to be processed and re-exported, the inward processing regime can take the question off the table entirely by suspending duty and VAT.
Each of those decisions belongs to a different discipline. Classification, valuation and the objection timetable are the day-to-day substance of customs law; measures aimed at a product or an exporter — surveillance, safeguards, anti-dumping and anti-subsidy action — belong with trade remedies, where the arguments are about the measure itself rather than about a single consignment. Where a subsequent assessment and a threefold penalty have already been issued, the fifteen-day sequence and its interaction with settlement are set out separately in our guide to customs administrative fines, objection and settlement.
The one thing that does not work is treating the threshold as though it were the law on value. The Communiqué that sets it says otherwise, and so does Article 26(2) of Law No. 4458.
