Importing into or exporting from Türkiye is rarely held up by the goods themselves. It is held up by paperwork that does not match, a tariff code chosen too quickly, or a preferential-origin claim nobody can support. Customs advisory exists to deal with those issues before a shipment leaves the warehouse.
This guide explains how customs works in Türkiye, where companies usually run into trouble, and how Ratin Teknoloji Group supports clients as an independent advisor and facilitator. Ratin is not a customs broker and does not lodge declarations. We work alongside licensed customs brokers (gümrük müşavirleri), freight forwarders and your own team to make sure each step is prepared properly.
How customs works in Türkiye
Türkiye has been in a Customs Union with the European Union since 1996. For most industrial goods this means a common external tariff and free circulation between Türkiye and the EU, supported by the A.TR movement certificate. Agricultural products, coal and steel products are outside the Customs Union and are covered by separate trade arrangements, so origin rules matter for them.
Türkiye has also signed a number of free trade agreements with other countries. Whether a shipment benefits from a reduced rate depends on the specific agreement, the product and whether the origin rules are met. Rates and rules change, so they should always be checked against the current official tariff for each shipment.
Customs procedures are run by the Ministry of Trade. Declarations are filed electronically, and in practice most companies use a licensed customs broker to file on their behalf.
Where companies usually run into trouble
Tariff classification. Every product needs a tariff code (GTİP in Türkiye). That code sets the duty rate, any additional duties, licence needs and whether preferential treatment applies. Codes are often copied from a supplier or an old shipment and never checked again. A wrong code repeated over many shipments can create a large back-payment when it is finally found.
Customs value. Duty is charged on customs value, which is not always the same as the invoice price. Depending on the Incoterm and the contract, freight, insurance, royalties, tooling supplied to the manufacturer or packing costs may need to be included. Leaving them out is a common audit finding.
Origin and certificates. A.TR, EUR.1, EUR-MED or origin declarations only help if the goods really meet the origin rules and the supporting records can be shown. Claiming preference without that support can lead to the duty being reclaimed later.
Documents that do not match. The commercial invoice, packing list, bill of lading or CMR, certificates and the declaration must tell the same story: same quantities, weights, descriptions and values. Small differences are one of the most frequent reasons a shipment is held.
Product-specific controls. Some goods need conformity checks, import permits, phytosanitary or veterinary certificates, or registration before they can be cleared. Minerals, agricultural inputs and food products often fall into these categories. These needs should be identified before the goods are shipped, not at the border.
Incoterms chosen by habit. The Incoterm decides who pays for and controls transport, insurance and clearance. Using the same term as the last contract, without checking it fits the deal, often leaves gaps in responsibility.
How Ratin supports you
Ratin's role is advisory and coordinating. Depending on the engagement, we can help with:
- Pre-shipment review of the product, the destination and the trade route, to identify classification questions, likely controls and required documents.
- Classification support, preparing the technical description and reasoning so your licensed broker can confirm the code, and flagging when a binding tariff information ruling may be worth requesting.
- Document workflow, setting up a checklist and review step so invoices, packing lists and certificates match before they are sent.
- Origin planning, checking with you whether a preferential claim is realistic and what records would be needed to support it.
- Incoterm and contract review, making sure delivery terms match who actually handles transport, insurance and clearance.
- Coordination between your team, your supplier or buyer, the freight forwarder and the customs broker, so each party knows what is needed and when.
Final classification, declarations and legal advice remain the responsibility of licensed customs brokers and qualified professionals. We help you prepare for them and work with them, and we say clearly where a question needs their formal opinion.
A simple checklist before you ship
- Confirm the tariff code with a licensed broker, using a clear product description.
- Check the duty rate, any additional duties and whether a trade agreement applies.
- Identify licences, certificates or conformity checks the product needs.
- Confirm the Incoterm and who arranges transport, insurance and clearance.
- Make sure all documents show the same quantities, weights, descriptions and values.
- Keep origin records if you plan to claim preferential treatment.
- Agree who will answer questions from customs if the shipment is selected for inspection.
