Most Common Customs Compliance Mistakes Made by Foreign Companies in Turkey (2026)

Common Customs Compliance Mistakes in Turkey | Foreign Companies 2026

Discover the most common customs compliance mistakes made by foreign companies in Turkey, including tariff, valuation, origin, documentation, licensing, and customs broker errors.

Foreign companies importing goods into or exporting goods from Turkey frequently assume that customs clearance is mainly the responsibility of the customs broker, freight forwarder, distributor, or local buyer. This assumption can create significant legal and financial risks.

Under Turkish customs practice, incorrect declarations may lead to additional customs duties, import VAT assessments, administrative fines, delayed shipments, post-clearance audits, seizure of goods, loss of customs privileges, or criminal investigations in serious cases.

Customs compliance should therefore begin before goods are shipped. Importers and exporters must verify the tariff classification, customs value, origin, licenses, product safety requirements, and accuracy of every document submitted to Turkish Customs.

The following are the most common customs compliance mistakes made by foreign companies operating in Turkey.

1. Using the Wrong Customs Tariff Code

One of the most common mistakes is declaring goods under an incorrect Customs Tariff Statistics Position, commonly known as the GTIP code.

Foreign companies often use:

• The tariff code provided by the foreign supplier
• A code previously used in another country
• A general code instead of a product-specific code
• The code used for a similar but technically different product
• A code selected only because it results in lower customs duties

However, tariff classification must be determined according to the objective characteristics of the product and the Turkish customs tariff.

The correct GTIP code may affect:

• Customs duty
• Additional customs duty
• Import VAT
• Special consumption tax
• Anti-dumping duty
• Import licenses
• Surveillance measures
• Product safety controls
• TAREKS requirements
• Import restrictions

Foreign businesses should keep technical catalogues, product specifications, photographs, composition details, manuals, and expert reports supporting the selected tariff classification.

2. Relying Entirely on the Customs Broker

A customs broker plays an important role in preparing and submitting customs declarations. However, appointing a customs broker does not automatically eliminate the importer’s legal responsibility.

The broker may not know:

• The complete commercial relationship between buyer and seller
• Whether additional payments were made
• Whether royalties are payable
• The actual manufacturing process
• Whether the parties are related
• The intended use of the goods
• Whether the supplier’s origin statement is accurate
• Whether free-of-charge items are included in the shipment

The importer should review and approve the customs declaration before it is finalized.

Companies should establish a written procedure requiring internal verification of:

• Tariff classification
• Customs value
• Country of origin
• Quantity
• Product description
• Applicable exemptions
• Tax calculations
• Permit references
• Supporting documents

3. Declaring Only the Invoice Price as Customs Value

Foreign companies frequently assume that customs value always equals the amount written on the commercial invoice.

In certain circumstances, customs value may also include:

• Freight and insurance expenses
• Packing costs
• Royalties and license fees
• Sales commissions
• Materials supplied by the buyer
• Moulds, tools, or designs provided free of charge
• Proceeds transferred to the seller after importation
• Certain related-party price adjustments

Turkey applies customs valuation methods beginning with the transaction-value method. Where that method cannot legally be applied, other valuation methods may be used.

Importers should ensure that customs declarations, purchase contracts, bank payments, transfer-pricing records, accounting entries, and royalty agreements are consistent.

4. Ignoring Related-Party Transactions

Transactions between related companies are commonly reviewed during customs audits.

A relationship between the buyer and seller does not automatically invalidate the declared customs value. However, customs authorities may investigate whether the relationship affected the price.

Common risk areas include:

• Transfer-pricing adjustments
• Management fees
• Year-end price corrections
• Royalties
• Technology fees
• Distribution agreements
• Discounts unavailable to unrelated buyers
• Costs paid by another group company

A company may comply with corporate tax transfer-pricing rules but still face a separate customs valuation issue.

Customs and tax departments should therefore coordinate their documentation and pricing policies.

5. Confusing Country of Dispatch with Country of Origin

The country from which goods are shipped is not necessarily the country of origin.

For example, goods may be shipped from a warehouse in one country but manufactured in another. Declaring the country of dispatch as the country of origin may result in:

• Incorrect preferential duty treatment
• Additional customs duties
• Rejection of origin documents
• Administrative penalties
• Anti-dumping exposure
• Surveillance measures

Companies should verify:

• Where the goods were manufactured
• Whether substantial transformation occurred
• Which origin rules apply
• Whether preferential origin conditions are satisfied
• Whether direct-transport requirements have been met
• Whether supplier declarations are accurate

6. Treating an A.TR Certificate as Proof of Origin

An A.TR movement certificate does not generally establish the origin of goods.

It mainly demonstrates that eligible goods are in free circulation under the customs-union framework between Turkey and the European Union.

A product may therefore be shipped from an EU country with an A.TR certificate while legally originating in a third country.

This distinction may be important where:

• Additional customs duties depend on origin
• Anti-dumping duties apply
• Trade-policy measures are imposed
• A certificate of origin is separately required
• Preferential origin must be proven under another agreement

Companies should determine whether they need an A.TR certificate, a certificate of origin, an EUR.1 certificate, an invoice declaration, or another origin document.

7. Using Vague Product Descriptions

Descriptions such as the following may be insufficient:

• Parts
• Samples
• Machinery
• Electronic equipment
• Accessories
• Components
• Chemical products
• Promotional goods

The customs declaration and commercial invoice should contain a description detailed enough to identify the product and verify its tariff classification.

A proper description may include:

• Product name
• Model
• Function
• Material
• Composition
• Brand
• Technical capacity
• Intended use
• Part number
• Serial number

Vague descriptions increase the risk of document requests, physical inspections, valuation questions, and tariff disputes.

8. Shipping Goods Before Obtaining Import Permits

Certain products require an import license, approval, registration, inspection, or conformity document before they can be released into free circulation.

High-risk product groups may include:

• Food products
• Agricultural goods
• Medical devices
• Pharmaceuticals
• Cosmetics
• Chemicals
• Electrical products
• Telecommunications equipment
• Machinery
• Toys
• Personal protective equipment
• Used goods
• Waste and scrap
• Batteries
• Automotive products

Shipping goods before confirming all legal requirements may lead to:

• Customs detention
• Storage costs
• Laboratory testing
• Re-export
• Destruction
• Administrative fines
• Contractual disputes

The importer should obtain written confirmation of product-specific requirements before dispatch.

9. Failing to Check Product Safety and TAREKS Requirements

Some foreign companies treat customs clearance and product safety compliance as separate matters. In practice, product safety requirements may directly prevent customs release.

Depending on the goods, companies may need:

• CE marking
• Declaration of conformity
• Technical file
• Test report
• Turkish instructions
• Safety warnings
• Manufacturer information
• Importer information
• TAREKS registration
• Product-specific inspection certificates

Documents should refer to the exact model, brand, product code, and manufacturer shown in the customs declaration.

A certificate issued for a different model or legal entity may be rejected.

10. Assuming Previous Clearance Guarantees Future Clearance

A product may have entered Turkey several times without difficulty. This does not guarantee that the same product will always be cleared under the same conditions.

Customs treatment may change because of:

• Annual Import Regime amendments
• Additional customs duties
• New product safety communiqués
• Revised tariff interpretations
• Origin measures
• Anti-dumping investigations
• Surveillance measures
• Updated laboratory standards
• Risk-analysis results

The Turkish Import Regime determines customs duties through product-based schedules and is updated through official regulations.

Companies should review current rules before every shipment rather than relying exclusively on previous declarations.

11. Providing Inconsistent Documents

Customs authorities compare information across multiple documents.

Common inconsistencies include:

• Different product descriptions
• Conflicting quantities
• Incorrect weights
• Different countries of origin
• Invoice values that do not match payment records
• Different importer names
• Missing freight expenses
• Incorrect container numbers
• Different delivery terms
• Unexplained free-of-charge goods

The commercial invoice, packing list, transport document, certificate of origin, customs declaration, contract, and payment records should be reviewed together before submission.

12. Failing to Declare Free-of-Charge Goods

Samples, promotional products, replacement parts, gifts, and warranty items may be supplied without payment.

However, the fact that goods are free of charge does not necessarily mean that they have no customs value or that they are automatically exempt from customs duties.

A reasonable customs value may still need to be declared.

The importer should maintain:

• Pro forma invoices
• Comparable sales prices
• Cost information
• Warranty documents
• Replacement agreements
• Explanation of the commercial purpose
• Freight and insurance records

13. Misusing Temporary Importation

Temporary importation may allow certain goods to enter Turkey without full payment of import duties, subject to strict conditions.

Common mistakes include:

• Exceeding the permitted period
• Using goods for an unauthorized purpose
• Transferring goods without permission
• Failing to re-export the goods
• Failing to notify customs of changes
• Selling temporarily imported goods
• Failing to discharge the guarantee
• Allowing unauthorized persons to use the goods

Temporary admission benefits should not be used unless the company can monitor deadlines, location, use, and re-export obligations.

14. Failing to Close Inward Processing Transactions

Companies using inward processing may import goods under conditional relief, process them, and export the resulting products.

Problems arise when:

• Export commitments are not completed
• Imported materials cannot be matched with exports
• Waste ratios are disputed
• Processing records are incomplete
• Deadlines expire
• Goods are sold domestically without proper customs procedures
• Guarantees are not discharged

Failure to close the relevant file may result in customs duties, taxes, interest, and penalties.

15. Ignoring Anti-Dumping and Trade-Policy Measures

A standard customs-duty calculation may not reveal the full cost of importation.

Additional measures may include:

• Anti-dumping duties
• Countervailing duties
• Additional customs duties
• Surveillance values
• Safeguard measures
• Quantity restrictions
• Origin-based financial obligations

These measures are often product- and country-specific.

A small difference in tariff classification or origin may therefore create significant additional liability.

16. Using Incorrect Incoterms

Incoterms define certain responsibilities between buyer and seller, but they do not override Turkish customs law.

A foreign company may agree to DDP delivery without understanding whether it can legally act as the importer in Turkey.

Problems may involve:

• Unclear importer status
• Undeclared freight and insurance
• Incorrect customs value
• Disputes over duties and taxes
• Lack of import permits
• Unexpected broker fees
• Storage liability
• Re-export costs

The sales contract should clearly allocate responsibility for customs clearance, duties, taxes, permits, documentation, delays, and non-compliant goods.

17. Failing to Preserve Customs Records

Companies sometimes keep only the final customs declaration and commercial invoice.

A complete customs file should also contain:

• Packing lists
• Transport documents
• Payment records
• Origin certificates
• Technical documents
• Product safety records
• Import permits
• Broker instructions
• Customs correspondence
• Inspection reports
• Laboratory reports
• Contracts
• Royalty agreements
• Accounting records

Customs authorities may examine transactions after the goods have been released. Missing records may make it difficult to defend an otherwise lawful declaration.

18. Making Unnecessary Amendments Without Legal Review

Foreign businesses may attempt to correct a customs declaration immediately after identifying an error.

Although voluntary correction may be appropriate in some cases, an amendment can also create evidence of an incorrect declaration or expand the scope of a customs investigation.

Before making a correction, companies should determine:

• The nature of the error
• Whether customs has already detected it
• Whether additional duty is payable
• Whether a penalty risk exists
• Whether other declarations are affected
• Whether a voluntary disclosure mechanism is available
• Whether criminal exposure exists

Legal advice should be obtained before submitting significant admissions or corrections.

19. Giving Inconsistent Statements During a Customs Audit

Customs officials may request explanations from employees, accounting personnel, customs brokers, logistics providers, or company managers.

Conflicting explanations can damage the company’s defense.

Before responding:

• Identify the responsible internal team
• Review the relevant documents
• Prepare a consistent factual chronology
• Avoid speculation
• Distinguish facts from assumptions
• Provide only verified information
• Keep copies of written submissions

Where substantial duties or criminal allegations may arise, statements should be reviewed by a customs lawyer.

20. Missing Objection and Litigation Deadlines

A strong legal defense may fail if the company misses the applicable deadline.

A formal customs decision may require:

• Administrative objection
• Payment under reservation
• Court proceedings
• Request for suspension of execution
• Criminal procedural application
• Appeal before a higher court

The notification date should be recorded immediately, and the complete decision should be reviewed by legal counsel.

Waiting for informal negotiations with customs officials does not necessarily stop statutory deadlines.

Consequences of Customs Compliance Mistakes

Depending on the violation, foreign companies may face:

• Additional customs duties
• Import VAT assessments
• Administrative fines
• Interest or delay charges
• Storage and demurrage expenses
• Delayed production
• Seizure of goods
• Re-export or destruction
• Loss of customs authorizations
• Post-clearance audits
• Anti-smuggling investigations
• Criminal proceedings
• Commercial and reputational damage

The financial impact often exceeds the original amount of customs duty.

How Foreign Companies Can Reduce Customs Risks

A reliable customs compliance program should include:

• Product-level GTIP records
• Customs valuation procedures
• Origin verification
• Approved supplier documents
• Pre-shipment controls
• Broker instructions
• Internal declaration approval
• Permit tracking
• Product safety checks
• Record-retention rules
• Periodic customs audits
• Employee training
• Rapid-response procedures
• Legal review of high-risk transactions

Companies should also compare customs declarations with accounting, tax, transfer-pricing, and inventory records.

2026 Legal Assessment

As of 2026, foreign companies should expect increased use of electronic customs records, risk analysis, post-clearance inspection, data comparison, and sector-specific import controls.

Current customs duty rates, additional duties, exemptions, and trade-policy measures should be checked under the legislation applicable on the customs declaration date.

The Ministry of Trade’s current guidance also shows that special procedures and duty rates may differ depending on the type of shipment and customs category.

A historical customs practice or previous clearance decision should not replace a current legal review.

Frequently Asked Questions

1. Is the customs broker responsible for every declaration error?

Not necessarily. The importer may continue to bear legal and financial responsibility even where a customs broker prepared the declaration.

2. Can Turkish Customs audit goods after release?

Yes. Customs authorities may conduct post-clearance reviews and examine earlier declarations and company records.

3. Is the commercial invoice always accepted as customs value?

No. Customs authorities may examine freight, insurance, royalties, assists, related-party pricing, discounts, and additional payments.

4. Can an incorrect tariff code result in a fine?

Yes. Incorrect classification may lead to additional customs duties, taxes, administrative fines, and further investigations.

5. Does an A.TR certificate prove EU origin?

No. An A.TR document generally proves free-circulation status rather than the origin of the goods.

6. Can free samples be imported without declaring a value?

Not automatically. Free-of-charge goods may still require a reasonable customs value and complete customs declaration.

7. Can companies correct customs declarations voluntarily?

Corrections may be possible, but their legal and financial consequences should be assessed before submission.

8. When should a foreign company consult a customs lawyer?

Legal support should be obtained where customs questions value, origin, tariff classification, permits, product safety, previous declarations, or possible criminal conduct.
