Türkiye is a natural hub for trade between Europe, the Middle East and Asia, and for any importer or exporter the customs regime is where commercial planning meets the tax bill. The framework is set by Customs Law No. 4458, which is broadly harmonised with the EU Customs Code, and it governs how goods are classified, valued and cleared, as well as the penalties for getting it wrong. For a foreign trading company the practical questions are consistent: what code and value apply to the goods, whether an origin proof can cut the duty, and which authorisations save time and cost. We help clients answer all of these before the first shipment moves.
The Customs Union, A.TR and Origin
The single most important feature of Turkish trade for an EU-facing business is the EU-Türkiye Customs Union, in force since 1996. It covers industrial goods and processed agricultural products, most of which move between Türkiye and the EU without customs duty when they travel in free circulation under an A.TR movement certificate. The Union deliberately does not cover basic agricultural products, coal and steel, or services, so those sectors follow the ordinary tariff and any applicable trade rules.

Origin sits alongside the A.TR. Duty-free treatment within the Customs Union rests on free-circulation status, evidenced by the A.TR, while preferential origin under one of Türkiye’s free-trade agreements, evidenced by a EUR.1 or EUR-MED certificate, can reduce or remove duty. Non-preferential origin governs trade-defence measures and labelling. The distinction is central to the wider import and export regime, and it is the first thing we test when planning a supply chain.
An A.TR proves free circulation, not origin. Using an A.TR where the trade actually requires a EUR.1 or EUR-MED origin proof (or vice versa) is a common and expensive mistake, because the wrong certificate can be rejected and the duty assessed after the goods have already been sold.
Classification and Customs Value
Two variables decide almost every customs outcome: the classification of the goods and their customs value.

Classification is done through the GTİP code (Gümrük Tarife İstatistik Pozisyonu), built on the international Harmonized System. The code drives the duty rate, the VAT rate and any measure attached to the product. Because the whole liability follows the code, we confirm classification up front and, where the position is genuinely uncertain, use a binding tariff ruling rather than leave it to chance at the border. What such a ruling actually binds, how long it survives and what a reclassification costs when the administration takes a different view later are set out in our note on tariff classification disputes and binding tariff information.
Customs value is normally the transaction value (the price actually paid or payable for the goods) adjusted to add elements such as freight and insurance to the place of entry, royalties payable as a condition of sale and commissions other than buying commissions, on the WTO Customs Valuation (GATT Article VII) basis. Since duty and import VAT are charged on this value, an understated price or an omitted royalty is a classic trigger for a later assessment.
Import Charges: Duty, VAT, ÖTV and Additional Duties
An import into Türkiye can attract several layers of charge, and the total is often well above the headline duty rate. The main components are these:
Read the full section
| Charge | Turkish name | Basis |
|---|---|---|
| Customs Duty | Gümrük Vergisi | Set in the lists annexed to the Import Regime Decree, by GTİP code and origin |
| Import VAT | KDV | Standard 20%, reduced 10% or 1%, on the customs value plus duties and charges paid on importation |
| Special Consumption Tax | ÖTV | On specific goods (e.g. fuels, vehicles, alcohol, tobacco) |
| Additional Customs Duty | İlave Gümrük Vergisi | Separate duty set by GTİP code and origin |
| Additional Financial Obligation | Ek Mali Yükümlülük | Separate charge on certain goods and origins; can apply alongside İGV |
The additional duties in the last two rows are the ones that most often surprise a new importer: they are two separate instruments, the same goods can attract both, and they most often reach goods from countries with no free-trade agreement with Türkiye. One further charge is decided by the payment terms rather than by the goods: where the price is paid after importation, the Resource Utilisation Support Fund (KKDF) may be levied on the import, and which payment methods trigger it is set out in our note on KKDF on deferred-payment imports. Modelling the full landed cost (and coordinating it with the client’s tax position) is part of getting the structure right before goods are ordered.
Trusted-Trader Status and Duty-Relief Regimes
Compliant traders can move goods faster and cheaper. The Authorized Economic Operator programme (Yetkilendirilmiş Yükümlü Statüsü, YYS) grants simplifications and lower-intervention clearance to traders that meet the reliability, solvency and security criteria. The status is also losable: the grounds on which a certificate is suspended or revoked, and the routes for challenging that decision, are a subject of their own, set out in our note on suspension and revocation of AEO status. Alongside it, Customs Law No. 4458 provides a set of duty-relief regimes that suspend or reduce charges where goods are not being placed on the domestic market for good:
Read the full section
| Regime | Turkish name | What it does |
|---|---|---|
| Inward Processing | Dahilde İşleme (DİR) | Import inputs with duties secured by a guarantee (or reclaim duties already paid) to process and re-export |
| Outward Processing | Hariçte İşleme | Send goods abroad for processing, re-import with partial relief |
| Customs Warehousing | Antrepo | Store goods not in free circulation under customs control, duty deferred |
| Temporary Importation | Geçici İthalat | Bring goods in temporarily (e.g. exhibitions) with relief; ATA Carnet |
| Transit | Transit Rejimi | Move goods through Türkiye under customs control (TIR / NCTS) |
The Inward Processing Regime is the workhorse for Turkish manufacturers and exporters: it lets them import raw materials and inputs without paying customs duties, which are secured by a guarantee that is released when the processed products are exported (Article 108 of Law No. 4458). It carries an export commitment and a time limit, and if the commitment is not met the secured duties become payable and administrative fines may follow. Closing that commitment is an application with its own deadlines rather than something that happens when the certificate expires, and what follows an unmet commitment is set out in our note on closing an inward processing authorisation. These regimes interact closely with free zones and the related customs regimes, and choosing between them is a planning exercise rather than a form-filling one.
Duty relief is conditional relief. Miss the export commitment or the time limit on an inward-processing authorisation and the secured duties become payable, with the risk of administrative fines, so the paperwork and the deadlines have to be managed as tightly as the production schedule.
Post-Clearance Control and the Audit-Ready File
Clearance is not the end of the story. Under Article 73 of Customs Law No. 4458 the administration may inspect commercial documents and data after the goods have been released and correct a declaration that rested on wrong or incomplete information: typically revisiting the same three variables it started with: classification, customs value and origin. That power is not open-ended: Article 197(2) requires under-collected duties to be notified within three years of the date the customs obligation arose, subject to exceptions, and the difference between that period and the longer record-retention obligations is set out in our note on the post-clearance notification period.

The compliance answer is documentary. For each declaration we keep the classification reasoning, the price and the dutiable additions, and the origin proof together as one file, so the position can be evidenced years later rather than reconstructed under pressure. Where the administration nonetheless raises an additional assessment or an administrative fine, the remedies run on short statutory deadlines and are handled separately: see customs disputes and penalty objections. Where the issue is a protective measure on dumped or subsidised imports rather than an ordinary assessment, it belongs to the field of trade remedies.
Our Approach
We act for importers, exporters and foreign trading companies across the compliance side of a customs matter: establishing the correct classification and value, planning origin and the duty-relief regimes, securing YYS and other authorisations, and supporting clearance and the evidence file behind it. Clearance is normally filed through a customs broker, and the form of representation decides who answers for the declaration: in indirect representation the broker declares in its own name but on the importer’s account, and Article 181(2) of Law No. 4458 makes the importer on whose account the declaration is lodged a debtor as well, while limiting the broker’s own liability to cases where it knew, or by profession should have known, that the data in the declaration were wrong. That is why the representation form and the power of attorney are settled before the first declaration rather than after an assessment: see the joint liability of customs brokers. Because customs sits at the intersection of tax, logistics and regulation, we coordinate it with our foreign-investment and trade work so the whole structure holds together.
