How does the customs warehousing procedure work?

Last updated:

Short Answer — Customs Warehousing Procedure

The customs warehousing procedure (antrepo rejimi) is a customs procedure with economic impact that allows foreign goods not released for free circulation to be stored in a customs warehouse under customs control without paying customs duties. The goods enter the procedure with a warehouse declaration and duties remain suspended; on exit, release for free circulation, re-export, transit or transfer to another procedure is chosen.

Legal framework of the customs warehousing procedure

The customs warehousing procedure is governed by Articles 93–107 of Customs Law No. 4458 (4458 sayılı Gümrük Kanunu) and is one of the customs procedures with economic impact listed in the Law; the others are inward processing, processing under customs control, temporary admission and outward processing. Implementation details are set out in the Customs Regulation (Gümrük Yönetmeliği). The essence of the procedure is this: the goods are physically in Turkey but are not yet considered imported for the purposes of duties and trade policy measures.

The procedure is open to two types of goods: foreign goods not in free circulation, and goods in free circulation placed in a customs warehouse in order to benefit from export-related measures. The storage facility itself is described in the entry what is a customs warehouse?.

What does the procedure offer the importer?

  • Duty deferral: Customs duty and VAT are not paid until the goods are withdrawn from the warehouse. Cash flow can be planned according to sales.
  • Partial withdrawals: A container load of goods can be brought in at once and released for free circulation as needed.
  • Time to decide: Whether the goods will be sold in Turkey or sent to a third country can be decided later.
  • Flexible duration: Under the legislation, the period goods may remain in a customs warehouse is unlimited as a rule; for perishable goods, the administration may set a time limit.

How does the procedure work step by step?

  1. Arrival and temporary storage: The goods are presented to customs with a summary declaration and wait in a customs-controlled area or temporary storage facility.
  2. Warehouse declaration: A warehouse declaration is registered for the goods; depending on the warehouse type, it is lodged by the operator or the user. For the procedure, see the entry how to lodge a warehouse declaration.
  3. Entry into the warehouse and stock records: The goods are entered in the warehouse stock records; quantity and description must match the declaration.
  4. Storage and handling: With the permission of the customs administration, the goods may undergo usual forms of handling intended to preserve them, improve their appearance or prepare them for sale, such as sorting, repacking and labelling.
  5. Discharge from the procedure: The goods are assigned another customs-approved treatment or use with a new declaration.

In which ways can goods leave the customs warehouse?

Exit routeWhat happens?Duties
Release for free circulationThe goods are imported into Turkey; in practice, a declaration with procedure code 4071 is lodgedPaid at the rate and exchange rate on the date of registration
Re-exportThe goods leave the customs territory of TurkeyNot paid
TransitThe goods are moved under customs supervision to another office or abroadRemain suspended under a guarantee
Another economic procedureE.g. transfer to inward processingThe provisions of the new procedure apply

Once the new declaration has been registered, customs formalities must be completed within 30 days. The scenario of selling to a third country is explained with examples in the entry re-export from a customs warehouse.

Who is responsible?

Customs warehouses are divided into public (types A, B and F) and private (types C, D and E). In a type A warehouse, the operator is responsible for the goods with regard to customs duties; in type B, the user is responsible; type F is operated by the customs administration. In private warehouses, the operator and the user are the same person. Duties and penalties for goods found missing from stock are claimed from the responsible person. For this reason, when choosing a customs warehouse, the type and the contract terms should be read together.

Common mistakes

  • Treating the customs warehouse as an ordinary warehouse and carrying out handling without permission.
  • Not matching declarations with stock records on partial withdrawals.
  • Not factoring changes in duty rates and exchange rate differences into the cost calculation.

Frequently Asked Questions

On which date is customs duty calculated for goods in a customs warehouse?
Duties are calculated not when the goods enter the warehouse but on the basis of the duty rates and exchange rate on the date the declaration for release for free circulation is registered. If the rate or the exchange rate changes while the goods are in the warehouse, the amount payable also changes. This difference should be taken into account in cost planning. For cargo that will be stored for a long time, changes to the tariff and additional customs duties published at the start of the year should also be monitored.
What is the main difference between a customs warehouse and an ordinary warehouse?
An ordinary warehouse holds goods in free circulation, i.e. goods on which duties have been paid, and there is no customs control. A customs warehouse holds foreign goods with suspended duties under customs supervision; entry, exit and handling are subject to permission. In addition, opening a customs warehouse requires authorisation from the Ministry of Trade (Ticaret Bakanlığı), whereas opening an ordinary warehouse does not. For a detailed comparison, see the entry difference between a warehouse and a customs warehouse.
