How do I challenge a customs revaluation and penalty for imported goods in Turkey?

Türkiye gümrük idaresi tarafından beyan edilen kıymetin artırılması ve faturaların kabul edilmemesi suretiyle ceza tesis edilmesi halinde, öncelikle 4458 sayılı Gümrük Kanunu’nun 242. maddesi uyarınca tebliğ tarihinden itibaren 15 gün içinde işlemi tesis eden gümrük idaresine idari itiraz yoluna başvurulması gerekmektedir. İdari itirazın reddedilmesi veya 60 gün içinde cevap verilmemesi halinde, ret kararının tebliğinden ya da zımni ret tarihinden itibaren 30 gün içinde vergi mahkemesinde dava açılması mümkündür.

Regarding the issue where Turkish Customs authorities have rejected the declared transaction value and issued penalties, please see the legal procedure and your rights below:

1. The Objection Process: Under Turkish Customs Law No. 4458, you have the right to object to the additional tax accrual and the fines.

Deadline: You must file a formal objection within 15 days from the date the notification (tebligat) was served.

Procedure: We can submit a petition to the relevant Regional Directorate of Customs and Foreign Trade (Gümrük ve Dış Ticaret Bölge Müdürlüğü). In this petition, we will present your bank transfer records (SWIFT copies) and the supplier contract as proof that the declared price is the actual transaction value (Article 24 of the Customs Law).

Alternative (Reconciliation): Instead of a direct objection, you may also apply for Reconciliation (Uzlaşma) within the same 15-day period to negotiate a reduction in the fines, though this usually implies accepting the higher valuation.

2. Release of Goods During Appeal: Yes, it is possible to clear your goods from customs while the legal process is ongoing.

Guarantee (Teminat): Under Article 202 of the Customs Law, you can withdraw the goods by depositing a guarantee (cash or bank letter of guarantee) covering the disputed tax amount and penalties. Once the legal process (objection or court case) concludes in your favor, this guarantee will be returned to you.

3. Next Steps: Please provide us with the official notification document (Ceza Kararı / Ek Tahakkuk) and the proof of payment matching the invoice. We will prepare the necessary petition immediately to meet the 15-day strict deadline.

This is first a valuation case, not just a penalty case

If Turkish Customs increased your declared value simply by saying the invoice is not acceptable, that is not the end of the analysis. In valuation disputes, Customs must explain why the transaction value, meaning the price actually paid or payable, cannot be used, and which alternative valuation method was applied instead.

If your supplier contract, bank transfer trail, commercial invoices, purchase orders and correspondence all match, that is often the core of a strong objection.

The first deadline is strict

The critical deadline is usually 15 days from the date the additional assessment and penalty notice was served. The objection should be filed against both the revaluation and the penalty, with the full supporting documents attached from the start.

In these files, importers often lose on timing and procedure before the merits are even examined, so the case should be prepared immediately.

Do not mix objection and settlement blindly

Many importers are told to try settlement first. That is not always the right move. Settlement may reduce exposure in some files, but it is not the same as a merits based challenge, and it should be chosen only after checking whether Customs had valid legal grounds to reject the declared price in the first place.

If your declared value is supported by clean payment records and genuine commercial documents, the stronger route is often to challenge the revaluation itself, not just negotiate the penalty.

Can the goods be released while the dispute continues?

Often yes, but not automatically. If the issue is an additional valuation and duty assessment, release can in many cases be sought against security. But if Customs is also relying on a separate seizure measure, anti-smuggling action or another blocking ground, the answer changes.

That is why the official notice matters so much: the exact legal basis determines whether the goods can be released during the challenge.

What usually wins these files

The winning point is rarely the invoice alone. The stronger argument is a complete and consistent commercial chain: supplier contract, purchase order, bank or SWIFT records, invoice, transport documents, insurance records, accounting entries, and proof that the seller and buyer are not manipulating the price.

If Customs relied on the value of same or similar goods, that comparison must also be tested carefully for date, quantity, commercial level and product characteristics. Generic benchmark values are not enough on their own.

The practical next step

Based on the facts you described, this looks like a file that should be challenged quickly and technically, not answered with a generic template letter. The first move is to review the notification itself, identify exactly which valuation method Customs used, build the evidence chain around the actual transaction price, and file a focused objection within the 15 day period.

If that is done properly, there is a real basis to attack both the revaluation and the penalty.
