GTIP code lookup: Finding the code and the risk of a wrong one

A GTIP code lookup is done on the uygulama.gtb.gov.tr/Tara screen that Turkey's Ministry of Trade points to for products to be exported (Ministry of Trade Support Management System: GTIP search page). That is the place to go if you want to confirm, before your first declaration, a Customs Tariff Statistics Position (GTIP, Turkish: GTİP), the 12-digit tariff code, taken from an earlier invoice or sent by your buyer. If the code stays unclear, the Ministry will not determine it for you, and you can apply for Binding Tariff Information (BTI, Turkish: BTB) (Ministry of Trade: tariff FAQ). The cost of a wrong code depends on whether the error affects the tax or the documents.

Where do you run a GTIP code lookup?

The official screen for checking a code is uygulama.gtb.gov.tr/Tara; the Ministry's Support Management System page gives this link for the GTIP numbers of products to be exported (Ministry of Trade Support Management System: GTIP search page). The tariff schedule itself can be reached chapter by chapter and downloaded from the Directorate General of Customs site, ggm.ticaret.gov.tr, in the "Türk Gümrük Tarife Cetveli" (Turkish Customs Tariff Schedule) section under "Mevzuat" (Legislation); the Ministry's 2023 Q&A text describes this route (Ministry of Trade: tariff FAQ).

The lookup screen speeds up your work, but the schedule has the last word. Under the Turkish Customs Law, the schedule, explanatory notes and goods index published in the Official Gazette are the basis for administrative and judicial practice (Customs Law No. 4458, current text).

Which year's schedule you read also matters, because customs duties are calculated under the tariff in force on the date the liability arises (Customs Law No. 4458, current text). The 2026 schedule was put into force by Presidential Decree No. 10781, effective January 1, 2026 (Alomaliye: text of decision 10781 on the 2026 tariff schedule). On July 11, 2026, the import regime and additional customs duty lists were also adjusted in line with changes to positions and goods descriptions (Ministry of Trade: 2026 import regime interim changes). Check a code you confirmed early in the year again after the July changes.

How do you find a GTIP code?

You find the code by comparing the product's detailed description with the tariff schedule and its explanatory texts; the Ministry says the schedule, explanatory notes, classification opinions and classification decisions can be consulted for this (Ministry of Trade: tariff FAQ). In practice, you can work in this order:

1. Write down the product's detailed description and trade name. The Ministry also makes these two items mandatory in a BTI application.

2. Look up the candidate code on the official screen (Ministry of Trade Support Management System: GTIP search page).

3. Test the candidate against the Turkish Customs Tariff Schedule, the Customs Tariff Schedule Explanatory Notes and the EU Combined Nomenclature Explanatory Notes. The official interpretation of the Harmonized System is given in the Explanatory Notes of the World Customs Organization (World Customs Organization: What is the Harmonized System?).

4. Look at BTIs issued for similar products. The BTB E-Başvuru Sistemi (BTI e-application system), in the E-İşlemler (e-services) menu of the Ministry's website, shows the GTIP, goods description, reference number, classification rationale and start of validity. A BTI binds the administration toward its holder (Customs Law No. 4458, current text); according to the Ministry, goods indisputably identical to those in a valid BTI are also classified in line with it. If your goods are only similar, do not rely on it.

5. Do not treat a code on a foreign document as proof. The tariff position on an invoice or transport document is not binding for Turkey and is used only for guidance.

What does the 12-digit GTIP tell you?

A 12-digit GTIP shows the product's international class, its EU sub-breakdown, Turkey's tax distinction and its statistical record in a single code (Ministry of Trade: tariff FAQ). Reading the Ministry's example, 540761 90 90 11:

The Harmonized System organizes more than 5,000 commodity groups under six-digit codes (World Customs Organization: What is the Harmonized System?). The first 6 digits should match in countries using the Harmonized System convention, and the first 8 digits should match in EU member states (Ministry of Trade: tariff FAQ). If your buyer's code and yours already diverge in the first 6 digits, one of you may have misclassified the product.

What is the risk of a wrong GTIP?

The risk depends on whether the error changes the tax payable or the documents required (Customs Law No. 4458, current text). The main consequences under the Customs Law are these:

• In release for free circulation and temporary import with partial relief, if the difference between the tax calculated from the declaration and the tax due exceeds 5%, a fine of three times the difference is charged on top of the tax; a tariff difference of 5% or less does not draw this threefold fine.

• In inward processing, processing under customs control and temporary import with full relief, the same difference brings an administrative fine of half the tax difference.

• In release for free circulation, if goods whose import depends on a license, permit or conformity document are declared as if they did not need one, any customs duty difference is collected and an administrative fine of twice the customs-cleared value is imposed. If the document is issued, or a positive inspection result is reported, within the period set by the Ministry, the fine is imposed under Article 241(1) instead; that amount is 1,494 TL for 2026 (General Customs Notice (Customs Procedures) No. 217, Official Gazette 2025). If the goods are worthless, scrap or waste, the fine is calculated per ton or per package and the goods are sent out of the country.

• If goods whose export depends on a document are declared as if they did not need one, an administrative fine of one tenth of the customs-cleared value is imposed; if the document is issued, or a positive inspection result is reported, within the period set by the Ministry, the fine is imposed under Article 241(1) instead.

• If the import of the goods is banned by a general regulatory act, the fine is four times the customs-cleared value; if the export is banned, it is twice that value.

It would be wrong to say that every wrong code automatically draws an irregularity penalty (Turkish: usulsüzlük cezası). Article 241(1) applies where the Law sets no separate penalty and on condition that the breach is expressly provided for in the regulation (Customs Law No. 4458, current text). A Constitutional Court decision dated March 26, 2026 annulled the part of that paragraph resting on secondary regulations, and the annulment took effect on June 2, 2026. The current text of the paragraph now refers only to breaches of the Law, so do not expect an automatic fine under it for a breach of a regulation or communiqué alone.

If you notice the error yourself, do not wait. For tax difference penalties, if the declarant reports the breach before the customs administration detects it, the penalty applies at a rate of ten percent (Customs Law No. 4458, current text). On the same condition, the document and ban penalties in Article 235(1) and (2) are reduced to ten percent of the calculated amount.

Suppose a wrong code on a declaration for release for free circulation led you to calculate 100,000 TL of tax and the correct code gives 130,000 TL: the 30,000 TL difference exceeds the 5% threshold, so on top of the declared tax you pay the difference and a 90,000 TL penalty, 120,000 TL before any interest, while reporting the error before the administration detects it cuts the penalty to 9,000 TL and the additional payment to 39,000 TL before any interest. The example does not cover late-payment interest, if any.

What should you do if you are unsure?

Apply for BTI, because the Ministry does not meet requests to determine a GTIP (Ministry of Trade: tariff FAQ). BTI is an administrative decision on the classification of goods in the schedule, given by the Ministry or the authorized regional directorates.

You can apply electronically or with a form matching the one in Annex 1 of the Customs Regulation (Ministry of Trade: tariff FAQ). According to the Ministry's 2023 text, applications go to the Istanbul, Central Anatolia, Aegean, Uludağ, Central Mediterranean and Eastern Marmara Regional Directorates of Customs and Foreign Trade. BTI is free of charge; the requester covers the costs of chemical analysis, expert examination or returning the goods.

The application must include the applicant, the holder, the customs tariff schedule, a detailed description of the goods, the trade name and additional information, attachments and a declaration; stating the classification you expect is optional (Ministry of Trade: tariff FAQ). Prepare the description with care, because binding information based on wrong or incomplete details is revoked (Customs Law No. 4458, current text).

BTI is valid for six years from the date of issue (Customs Law No. 4458, current text). This period is no absolute guarantee:

• It binds the customs administration only on the tariff position and only for procedures completed after the date the information was given.

• You must prove that the goods you declare match the goods described in the information in every respect.

• If the schedule changes and the information no longer fits the new provision, or it no longer fits a change in World Customs Organization decisions, validity ends on the date the change is published in the Official Gazette.

• A BTI that loses validity for a reason other than wrong or incomplete details can be used for 6 more months if you prove that you had already concluded a binding purchase or sale contract relying on it; if an import, export or prior authorization document is presented during the procedure, that document's period is what counts (Ministry of Trade: tariff FAQ).

Which documents does the code call for?

The required document never appears in the GTIP itself; you find it by searching for the code in Turkey's or the target market's code lists. The Eurasian Economic Commission's list for meat products is a clear example: 282 codes in 11 product groups are broken down to the tenth digit, and these codes identify the products whose conformity is to be confirmed during customs procedures (Eurasian Economic Commission: code list for the meat products technical regulation).

On the Turkish side, the import communiqués are reviewed at the start of each year (Ministry of Trade: 2026 import regime announcement). The 2026 communiqués changed the list for inspection of conformity to standards, added new GTIPs to the waste list and removed one GTIP from the Ministry of Health special permit list (KPMG: 2026 product safety and inspection notices bulletin). Search for your code in the current communiqué instead of relying on last year's result. Export lists are also updated by amendments, so confirm their current versions with the Ministry of Trade.

In the Eurasian market, lists are written in the Union's own codes, and your common ground with the GTIP is the first 6 digits (Ministry of Trade: tariff FAQ; Eurasian Economic Commission: code list for the meat products technical regulation). These lists are not fixed either: in the 2022 update, the standard changed for 24 positions, 23 of them were replaced by a new edition and one was removed because of cancellation (Eurasian Economic Commission: unified list of products subject to mandatory conformity assessment).

In Saudi Arabia, products are added to SABER by HS code; if the code is unavailable, you can search by keyword (Saudipedia: guide to the Saudi Saber platform). According to a 2021 guide by the logistics company Crane, Saudi Arabia uses its own 12-digit code, so do not carry your GTIP over directly; confirm the code in the Saudi tariff with your Saudi importer (Crane Worldwide Logistics: SABER system guide). The same guide says responsibility for registration lies with the Saudi importer, regulated products need product and shipment conformity certificates, and the shipment certificate requires a commercial invoice and packing list. Because the Saudi customs code determines which technical regulation applies and whether SASO or SABER is required, a wrong code can point to the wrong regulation.

Once the code is clear, our certification services can help you match your product with the document the target market requires.
