Glossary / GTİP
GTİP — explained
GTİP is the 12-digit code that shows the classification of goods in Türkiye’s Customs Tariff Schedule; this code determines which customs duty rate a product is subject to and which permits and documents it requires.
The first six digits of the code are based on the internationally used Harmonized System (HS); Türkiye completes these six digits to twelve in its own Customs Tariff Schedule. The Schedule is prepared every year by the Ministry of Trade and published in the Official Gazette as a Presidential Decision; for this reason, a GTİP that was correct in one year may not remain the same the following year.
GTİP is not merely a classification label: the customs duty and VAT rate, any additional fiscal charge, and the control or conformity document (health, agricultural, standards) a product is subject to are all tied directly to this code. The same product can be assessed under a different chapter when presented at a different degree of processing or with different technical specifications.
The first part of the code is internationally shared; the last part is specific to Türkiye. For this reason, an HS code received from a supplier or buyer abroad may not be identical to the full GTİP under Turkish legislation; the national completion also needs to be checked separately.
When You Encounter It
Determining the GTİP is the very first step of the customs process: before the declaration is registered, which duty rate and which permit will apply is determined through this code. When the order is reversed — that is, when the declaration is prepared first and the GTİP is only clarified afterwards — the goods usually end up waiting at the port or in the customs warehouse once a missing permit or document is noticed. You can check the current code and duty rate using our GTİP lookup tool.
In practice, the degree of processing a product has undergone can change its tariff heading: raw material, semi-processed and finished states are often placed under different chapters. This distinction is clarified with photographs, a technical description and, where necessary, a sample; it is not guessed from the commercial name.
What It Doesn't Cover
- Determining the GTİP is not a final, indisputable search result — it is a classification decision. The same product can be argued differently depending on which technical features are emphasised, and the authority may hold a different view.
- For a disputed or recurring product, an application for Binding Tariff Information (BTI) can be made, which makes the classification binding on the authority; this is a separate application process from the GTİP itself.
Often Confused With
| Comparison | Difference |
|---|---|
| GTİP vs HS Code | The HS Code is the World Customs Organization’s 6-digit international classification. GTİP is the national code that completes these 6 digits to 12 under Türkiye’s own legislation — the first 6 digits are the same, the remaining 6 are specific to Türkiye. |
| GTİP vs Binding Tariff Information (BTI) | BTI is a separate application and decision process that makes a GTİP determination binding on the authority; it is not the GTİP itself, but a document that closes off in advance any dispute about the GTİP. |
Frequently Asked Questions
What is a GTİP code?+
GTİP is the 12-digit numerical code that shows where goods sit in the customs tariff schedule. Its first 6 digits are based on the internationally shared Harmonized System; the remaining 6 digits are based on Türkiye’s own tariff schedule.
How many digits does GTİP have?+
It has 12 digits. The first 6 digits are the same as the international Harmonized System code; the 7th digit onwards is national detail specific to Türkiye’s Customs Tariff Schedule.
What does "GTİP no" mean?+
In everyday use, "GTİP no" is synonymous with the GTİP code — it refers to the good’s 12-digit position in the tariff schedule. This number is the key that determines the duty rate and the set of permits/documents required.
How often are GTİP codes updated?+
Türkiye’s Customs Tariff Schedule is prepared every year by the Ministry of Trade and published in the Official Gazette as a Presidential Decision. A code that was correct in one year can change once the schedule is updated; for recurring products, the code should be checked again at the start of each year.
