How can foreign companies defend a low import price challenged by Turkish Customs? Learn the required evidence, customs valuation methods, related-party risks, penalties and appeal options in 2026.
A low import price does not automatically mean that the importer under-declared the customs value. International transactions may legitimately involve volume discounts, promotional pricing, distressed inventory, new-market strategies, seasonal reductions, product defects or special contractual terms.
Nevertheless, Turkish Customs may investigate an invoice that appears significantly below comparable transactions or historical prices. The importer and foreign supplier must then demonstrate that the price is genuine, commercially justified and properly recorded.
If the explanation is not accepted, Customs may reject the transaction value, apply an alternative valuation method and assess additional customs duty, import VAT, interest and penalties.
An artificially low import price is a price that Customs believes does not reflect the actual amount paid or payable for the imported goods.
Customs may suspect artificial pricing where:
A low price can still be lawful. The issue is whether it is supported by objective, quantifiable and contemporaneous evidence.
The first question is whether the transaction value can be accepted. This generally means the price actually paid or payable for goods sold for export to Turkey, subject to legally required additions.
The Turkish Ministry of Trade explains the transaction-value method and the sequence of alternative valuation methods in its official customs valuation guidance.
The importer should explain why:
Customs should not replace a genuine transaction value merely because it appears commercially unusual.
Foreign companies may defend a low price by documenting:
The explanation should be supported by documents created before or at the time of the transaction. A justification prepared only after Customs begins an investigation may receive less weight.
A foreign company should prepare a transaction-value evidence file containing:
A written reconciliation should connect the invoice, payment, customs declaration and accounting entry for every shipment under review.
Bank records are often decisive. Customs may compare:
A difference between invoice and bank transfer does not automatically prove undervaluation. It may result from bank charges, multiple invoices, deposits, freight payments, credit notes or currency conversion.
The company should prepare a clear payment reconciliation explaining every difference. If a parent company or group entity paid the supplier, the legal and accounting basis should be documented.
A low price in a related-party transaction attracts greater scrutiny, but related-party status does not automatically invalidate the transaction value.
The importer should provide:
The defence should show that the price was determined under commercial conditions and that the relationship did not influence the amount declared to Customs.
Transfer-pricing and customs valuation analyses should be coordinated. However, they are separate legal assessments. A price accepted for income-tax purposes may still require a specific customs explanation.
Even where the invoice price is genuine, Customs may ask whether legally required additions were omitted.
Potential additions may include:
These additions must be based on objective and quantifiable data. The importer should analyse each item separately rather than accepting an unexplained adjustment.
Costs that may be excluded when separately identified can include post-import transport, certain post-importation assembly, qualifying financing interest, buying commissions and import taxes.
Customs may compare the declared price with:
A comparison is meaningful only if differences in quantity, quality, model, delivery term, warranty, origin, date and market are taken into account.
The importer may challenge a comparison based on goods that are not commercially comparable. A reference value should not automatically replace a genuine transaction price without a legally sufficient valuation analysis.
If Customs rejects the transaction value, it may consider:
The importer should request a detailed explanation of the method used and the adjustments made. The authority should identify the comparable goods, data sources and calculation steps.
A decision that simply states that the price is “too low” may be challenged if it does not adequately explain why the transaction-value method was unavailable.
A low-price investigation may begin after the goods have already been released. Customs may review:
Under the general framework of Customs Law No. 4458, under-assessed customs duties may generally be notified within three years from the date the customs debt arose, subject to statutory exceptions.
The importer should preserve all relevant documents and review the declarations covered by the audit. It should not provide unrelated historical data without understanding the legal scope of the request.
If Customs concludes that the declared price was artificially low, the importer may face:
A formal accounting error may be treated differently from an intentional false declaration. If Customs suspects fabricated invoices, hidden payments or deliberate duty evasion, further administrative or criminal investigation may be considered.
A low price alone does not automatically establish fraud or criminal intent.
A foreign company should:
The response should be factual, consistent and supported by contemporaneous records. Documents should never be backdated, altered or created solely for the investigation.
The importer may challenge:
Under Article 242 of Customs Law No. 4458, an objection is generally filed within 15 days from lawful notification of the customs decision.
If the objection is rejected, proceedings may be brought before the competent tax court within the applicable procedural period. A lawsuit does not automatically suspend collection. A separate suspension-of-execution request may be necessary where immediate payment would cause serious and difficult-to-repair harm.
Settlement may be available for certain customs debts and penalties. The importer should compare settlement with litigation and contractual recovery from the supplier.
In 2026, Turkish Customs increasingly compares declared prices with:
Foreign companies should maintain a permanent customs valuation policy, document discount structures before shipment and ensure that finance, sales, procurement and customs teams use consistent information.
1. Is a low import price automatically illegal in Turkey?
No. A low price may be lawful if it is commercially justified and supported by objective evidence.
2. Can Turkish Customs reject an invoice without proving fraud?
Yes. Customs may reject the transaction value without a criminal finding, but it should provide a legally sufficient valuation reason.
3. What is the strongest evidence of the actual price?
Contracts, purchase orders, bank records, supplier confirmations, accounting entries and a clear payment reconciliation are usually important.
4. Can promotional discounts be accepted?
Yes, if the discount was genuine, commercially available or contractually agreed and supported by contemporaneous records.
5. Are related-party transactions automatically rejected?
No. The importer can prove that the relationship did not influence the price.
6. Can Customs request the foreign supplier’s bank records?
It may request payment evidence through the importer, exporter or relevant customs authority during a valuation investigation.
7. Can Customs add royalties to the invoice value?
Potentially, where the royalty relates to the imported goods and is a condition of sale. The agreement and payment structure must be examined.
8. Can Customs use a reference price instead of the invoice?
Only where the transaction value cannot be accepted under the valuation rules. The method and calculation should be explained.
9. What is the deadline to object to the assessment?
An objection is generally filed within 15 days from lawful notification under Article 242 of Customs Law No. 4458.
10. Can a foreign company directly challenge the Turkish customs debt?
The Turkish importer generally faces the customs assessment, while the foreign company supports the defence and may pursue contractual remedies.
