Bonded Warehouse vs Temporary Storage in Turkey: Costs

In short: temporary storage is the short waiting period after goods arrive at customs: 45 days for sea freight and 20 days for other modes, with no duty paid. A bonded warehouse is a customs procedure for longer storage: imported goods can stay without paying duty, and simple handling such as repacking or labelling is allowed. Temporary storage costs rise quickly with time; a bonded warehouse adds a guarantee and reporting but lets you defer duty and VAT until the goods leave.

Introduction to Customs Storage Regimes

In international trade, goods entering a customs territory do not always need to be released into free circulation immediately. The need to store goods under customs supervision may arise for various commercial, logistical, or financial reasons. This is precisely where the bonded warehouse regime and temporary storage procedures come into play.

Turkey's customs legislation, under Customs Law No. 4458, provides a comprehensive framework for the storage of goods in customs-controlled areas. These regulations offer importers and exporters significant flexibility and cost advantages.

Choosing the right storage regime does more than just optimize customs costs — it is also a critically strategic decision for cash flow management, inventory planning, and logistics efficiency.

Temporary Storage: Essential Information

What Is Temporary Storage?

Temporary storage refers to the holding of goods presented to customs under customs supervision until they are assigned a customs-approved treatment or use. During this process, goods retain their customs status and no customs duties are paid.

Temporary Storage Periods

• Goods arriving by sea: 45 days from the date the summary declaration is filed (Customs Law No. 4458, Art. 46)
• Goods arriving by other modes: 20 days from the date the summary declaration is filed
• Extensions are possible with customs authority approval but are applied only in exceptional circumstances
• If no customs-approved treatment is applied by the end of the period, goods are subject to disposal proceedings

Temporary Storage Facilities

Temporary storage facilities are areas authorized by customs authorities:

• Port areas: Container terminals and storage areas at seaports
• Airport cargo terminals: Specialized storage facilities for air freight
• Land border gates: Parking and storage areas at customs crossings
• Inland customs offices: Customs-controlled storage areas within cities

Temporary Storage Costs

The main costs arising during the temporary storage process:

• Storage charges (ardiye): Daily or weekly fees for the storage area used
• Handling charges: Costs for unloading, loading, and moving goods
• Terminal Handling Charge (THC): Fixed service fee applied at container terminals
• Demurrage: Penalty paid to the shipping line when the container return period is exceeded
• Detention charges: Fee paid for keeping the container outside the port beyond the allowed period

Costs in temporary storage increase exponentially as the duration extends.

Bonded Warehouse Regime

What Is the Bonded Warehouse Regime?

The bonded warehouse regime is a customs procedure that allows imported goods — and, under certain conditions, export goods — to be stored in customs bonded warehouses without being subject to customs duties and without the application of trade policy measures.

The key difference from temporary storage is that goods under the bonded warehouse regime can be stored indefinitely (Customs Law No. 4458, Art. 101) and various handling operations can be performed on them during this period.

Types of Bonded Warehouses

Bonded warehouses in Turkey are classified into two main categories:

General Warehouses: Warehouses where goods may be placed by anyone. There are three subtypes:

• Type A General Warehouse: The warehouse operator keeps the stock records and is liable for customs duties on any shortage (Customs Regulation, Art. 329)
• Type B General Warehouse: Each goods owner is individually responsible; the warehouse operator bears general responsibility
• Type F General Warehouse: Operated by the customs authority

Private Warehouses: Warehouses where only the operator's own goods are stored. There are three subtypes:

• Type C Private Warehouse: Standard private warehouse for the operator's own goods
• Type D Private Warehouse: The customs value and other elements of taxation are determined on the date the goods enter the warehousing procedure
• Type E Private Warehouse: A physical warehouse space is not mandatory; goods may be stored at any location approved by the customs authority

Opening and Operating a Bonded Warehouse

Conditions and process required to open a bonded warehouse:

Physical Requirements:

• Secure area suitable for customs supervision
• Adequate covered or open storage space
• Fire safety and insurance conditions met
• CCTV system and security infrastructure
• Weighing and measuring equipment

Administrative Requirements:

• Application to the customs authority and deposit of a guarantee
• Obtaining an operating permit
• Establishing an inventory tracking system
• Appointing responsible personnel

Application Process:

1. Application to the relevant customs directorate with a petition and required documents
2. Physical inspection and suitability assessment
3. Determination and deposit of the guarantee amount
4. Issuance of the permit

Permitted Operations in Bonded Warehouses

The following handling operations may be performed on goods in the warehouse:

• Ventilation, drying, cleaning
• Packaging, repackaging, labeling
• Taking samples
• Simple assembly or disassembly operations
• Maintenance required for the preservation of perishable goods
• Quality control and counting

Important: Handling operations must not alter the nature or HS code of the goods. Manufacturing operations cannot be performed under the bonded warehouse regime; the Inward Processing Regime is required for that purpose.

Cost Comparison

Temporary Storage vs. Bonded Warehouse Regime

A detailed analysis comparing the cost structures of the two regimes:

Sample Cost Calculation

Scenario: 2 containers (40' HC) of machine spare parts, CIF value $200,000, customs duty 5%, VAT 20%

Direct Import:

• Customs Duty: $200,000 x 5% = $10,000
• VAT: ($200,000 + $10,000) x 20% = $42,000
• Total tax burden: $52,000 (payable immediately)

Bonded Warehouse Regime (6-month storage):

• Warehouse storage charges: ~$3,000 (6 months)
• Tax deferral interest savings: ~$52,000 x 15% x 6/12 = ~$3,900
• Net savings: ~$900 + cash flow advantage

Cash Flow Impact

One of the most important advantages of the bonded warehouse regime is the deferral of customs duties until goods are released from the warehouse. This:

• Improves the importer's cash flow
• Enables inventory management without tax burden
• Allows flexible sales planning based on market conditions
• Permits delivery of goods to different customers at different times

Choosing the Right Regime

Choose Temporary Storage If:

• Your goods will be cleared through customs within a short period (20–45 days)
• You need short-term waiting for document preparation or laboratory analysis
• You are conducting one-time or low-volume imports
• You need to wait during transit passage

Choose the Bonded Warehouse Regime If:

• You plan to keep goods in a customs-controlled area for an extended period
• Cash flow management is critically important to you
• You need to perform handling operations on the goods
• You will deliver to different customers at different times
• There is a possibility of re-export
• You conduct regular and high-volume imports

Key Considerations for Bonded Warehouses

Inventory Management and Reporting

• Stock records for goods in the warehouse must be kept current
• Regular reporting to the customs authority is required
• Inventory discrepancies can lead to serious penalties
• The use of a digital inventory management system is strongly recommended

Insurance and Security

• Comprehensive insurance should be obtained for goods in the warehouse
• Fire, theft, and natural disaster risks must be covered
• 24/7 security and CCTV systems are mandatory
• Additional security measures are required for hazardous materials storage

Duration and Disposal Risks

• While storage in a bonded warehouse is indefinite, the customs authority may request that goods be assigned a customs-approved treatment after a reasonable period has passed
• Abandoned or unclaimed goods are subject to disposal proceedings
• Special time limitations may apply to perishable or hazardous goods

2026 Developments and Trends

Current developments in the warehouse and storage space:

• Smart warehouse systems: IoT sensors, RFID tagging, and automated inventory tracking
• Green warehouses: Incentives for energy-efficient, environmentally friendly storage facilities
• Blockchain-based inventory management: Transparent and reliable inventory tracking chains
• E-warehouse declarations: Fully digital warehouse entry and exit procedures
• Regional warehouse networks: Logistics networks integrating multiple warehouses

Frequently Asked Questions

What is the purpose of temporary storage of goods? It keeps goods that have been presented to customs under supervision until they are assigned a customs-approved treatment, such as release for free circulation, the bonded warehouse regime or re-export. The goods keep their customs status and no duty is paid during this period, which is limited to 45 days for sea freight and 20 days for other modes.

How much does a bonded warehouse cost? The main items are the warehouse's storage charges, the guarantee deposited with customs and the cost of stock records and reporting. In the example above, six months of storage for two 40' containers costs about $3,000, against about $3,900 saved by deferring $52,000 of duty and VAT. Actual charges depend on the warehouse and the goods.

How long can goods stay in a bonded warehouse? There is no general time limit under the bonded warehouse regime, unlike the 20–45 days of temporary storage. Special limits may apply to perishable or hazardous goods.

Can goods be processed in a bonded warehouse? Only usual handling that does not change the nature or HS code of the goods: cleaning, repacking, labelling, sampling, simple assembly or disassembly. Manufacturing requires the inward processing regime.

Conclusion

Temporary storage and the bonded warehouse regime are powerful tools for cost optimization and logistics management in international trade. Choosing the right regime depends on multiple factors including trade volume, product type, storage duration, and financial objectives.
