Turkish Customs replaces an importer’s declared price with a higher comparable value. Learn when comparable pricing can be challenged, what adjustments Customs should consider, and which evidence importers should submit.
Turkish Customs may question the declared value of imported goods and rely on the transaction value of identical or similar goods to determine a higher customs value.
For example:
Importer’s declared price: USD 80 per unit
Customs comparable price: USD 125 per unit
The difference may result in substantial additional customs duties, import taxes, late-payment amounts and administrative penalties.
However, the fact that Customs has identified another import at a higher price does not automatically mean that the higher value is legally correct.
Turkey’s customs valuation framework applies valuation methods sequentially. The transaction-value method is examined first. Only where customs value cannot properly be determined under that method should the subsequent valuation methods be considered.
An importer facing a higher comparable value should therefore investigate two separate issues:
Was Customs entitled to move away from the importer’s transaction value?
and
Was the comparable transaction selected and adjusted correctly?
The existence of another shipment imported at a higher price does not by itself establish the customs value of the disputed goods.
The valuation framework does not operate on the principle:
“Another importer paid more, therefore your goods must have the same value.”
Customs must apply the legally prescribed valuation methodology.
Before analyzing the comparable price, determine why Customs did not accept the price actually paid or payable.
Possible concerns may include:
The importer should address the reason for rejecting transaction value before focusing exclusively on the comparable shipment.
The Ministry of Trade identifies six principal customs valuation methods:
As a general rule, the next method should not be used if the customs value can properly be determined under the preceding method.
This sequencing can be an important ground of objection.
The importer should determine whether Customs relied on:
Identical goods
or
Similar goods.
These concepts are not interchangeable.
The evidence required to challenge them may differ.
Official Ministry guidance describes identical goods as goods that are the same in all respects, including physical characteristics, quality and reputation, subject to minor differences in appearance, and produced in the same country.
Therefore, ask:
Similar goods need not be identical in every respect.
According to Ministry guidance, they should have similar characteristics and component materials enabling them to perform the same functions and be commercially interchangeable, with factors such as quality, reputation and trademark also relevant.
This gives importers several potential grounds for challenging an inappropriate comparison.
The official definition requires attention to the country in which the goods were produced.
A comparable price should therefore not be accepted without examining the origin of the supposedly identical or similar goods.
Official guidance also addresses the producer of the comparable goods.
Where qualifying identical or similar goods produced by the same person are unavailable, goods produced by another person may be considered under the relevant conditions.
The importer should therefore identify the manufacturer behind the comparable transaction.
Two products from the same manufacturer may differ significantly.
Compare:
A newer or premium model should not automatically determine the value of a lower-specification product.
Particularly under the similar-goods analysis, commercial reputation and trademark can be relevant.
A premium international brand and an unknown manufacturer may sell technically similar products at substantially different prices.
That commercial difference should not be ignored.
Suppose Customs compares:
Comparable transaction: 100 units at USD 125 each
with
Importer transaction: 50,000 units at USD 80 each.
A substantial volume discount may explain much of the difference.
Official Ministry guidance states that the valuation of identical or similar goods should consider approximately the same quantity and that proven adjustments may be necessary where quantities differ.
Useful evidence includes:
Do not merely state:
“We buy more.”
Prove the commercial effect.
Prices can vary significantly between:
Manufacturer → national distributor
and
Manufacturer → small wholesaler
or
Manufacturer → retailer.
Official Ministry guidance requires consideration of differences in commercial level when identical or similar transactions are compared.
Submit evidence showing whether the importer is:
This can explain legitimate pricing differences.
The identical- and similar-goods methods refer to transactions involving goods exported at the same or approximately the same time as the goods being valued.
A substantially older transaction may be commercially misleading where market prices changed rapidly.
Prices may fall because of:
Contemporaneous market evidence can therefore be important.
Suppose one transaction involves:
Air freight
while another involves:
Sea freight.
The transportation costs may be dramatically different.
Official guidance provides for adjustments where significant differences arise from transportation distance and mode.
Determine whether the compared prices include equivalent insurance arrangements.
A comparison should be made on a consistent valuation basis.
Compare:
Two invoices showing USD 100 and USD 120 may not actually reflect different goods values if one price incorporates substantially more transportation or delivery costs.
Normalize the comparison.
A lower transaction price may result from:
Provide contemporaneous documentation showing why the discount was granted.
Goods may be:
These differences can materially affect commercial value.
Technology products, machinery and automotive components can lose value rapidly when newer generations enter the market.
A 2024 model imported in 2026 should not automatically be valued according to a current-generation 2026 model.
Prepare a comparison such as:
| Factor | Imported Goods | Customs Comparable |
|---|---|---|
| Model | A100 | A150 |
| Capacity | 50 units/hour | 80 units/hour |
| Production year | 2024 | 2026 |
| Warranty | 1 year | 3 years |
| Quantity | 10,000 | 500 |
| Commercial level | Distributor | Retail wholesaler |
A table can immediately expose weaknesses in the comparable selected by Customs.
Where identical or similar goods are sold at a different commercial level or quantity, official guidance permits the use of that transaction after appropriate adjustments, provided the reasonableness and accuracy of the adjustment are supported by clear evidence.
The importer should therefore propose a documented adjustment rather than merely rejecting Customs’ comparison.
Adjustments are not necessarily designed only to increase customs value.
Official Ministry guidance expressly contemplates adjustments that may result in an increase or decrease, provided their reasonableness and accuracy are established.
This can be particularly important for large-volume importers.
This is an important protection.
The Ministry states that where more than one transaction value for identical goods is identified under the relevant method, the lowest of those values is used to determine customs value. The same principle is stated for qualifying similar goods.
Therefore, ask whether Customs identified more than one qualifying comparable.
The importer should seek sufficient information to understand:
Without understanding the basis of the comparison, meaningful objection becomes difficult.
Customs may not necessarily disclose another company’s confidential commercial information in full.
However, the importer still needs enough information concerning the valuation methodology and relevant characteristics to challenge the assessment effectively.
The objection should identify what information is necessary for the defense.
If the buyer and seller are related, Customs may scrutinize whether the relationship influenced the price.
But official Ministry guidance states that the existence of a relationship alone is not sufficient to reject transaction value.
The surrounding circumstances of the sale should be examined.
Useful documents may include:
However, transfer-pricing documentation and customs valuation should not be treated as identical legal analyses.
Before challenging Customs aggressively, verify whether the importer made additional payments involving:
Certain amounts may legitimately require inclusion in customs value.
Prepare:
Invoice
→ bank payment
→ accounting record
→ customs declaration.
Explain every difference.
A transparent payment trail substantially strengthens the valuation defense.
If the case reaches the fall-back valuation method, Customs still does not have unlimited discretion.
Official Ministry guidance states that customs value under that method cannot be based on arbitrary or fictitious values, minimum customs values, the domestic price in the exporting country, or a system automatically selecting the higher of two alternative values.
This is the key principle.
The customs valuation system does not simply authorize Customs to find a higher number.
The authority should be able to explain:
Why transaction value was unavailable
→ which subsequent valuation method applies
→ why the selected goods qualify as identical or similar
→ what adjustments were made.
Review:
Check the mathematics as well as the legal methodology.
Even where a valuation adjustment survives, any administrative penalty should be independently examined.
The Ministry’s customs-value guidance identifies significant penalties that may arise from deficient value declarations under Article 234, making it particularly important to test the precise statutory basis and calculation in each case.
There is an important factual difference between:
a legitimate volume-discount dispute
and
an undisclosed payment to the seller.
The importer should establish which type of case actually exists.
If Customs increases the value of one shipment, previous declarations from the same supplier may also be examined.
Prepare a matrix containing:
Declaration date
Product
Quantity
Invoice value
Unit price
Payment
Discount
Customs status.
First determine whether Customs’ valuation method is legally and factually correct.
Premature corrections can unnecessarily expand the company’s exposure.
Ask the foreign supplier to confirm:
Contemporaneous supplier records are preferable to a vague letter prepared after the dispute begins.
Supplier pricing changes over time.
Obtain the price list applicable when the disputed sale occurred rather than relying only on today’s prices.
For high-value disputes, independent evidence may help establish:
The evidence should address the precise valuation methodology used by Customs.
A company should not spend weeks negotiating informally while the formal challenge period expires.
Record the notification date of every assessment and penalty immediately.
Prepare the substantive evidence in parallel with the procedural challenge.
For recurring imports, maintain:
This can substantially reduce future valuation disputes.
The recommended sequence is:
Identify why transaction value was rejected
→ identify the valuation method used
→ obtain information concerning Customs’ comparable
→ determine whether the goods are genuinely identical or similar
→ compare manufacturer and country
→ compare quantity
→ compare commercial level
→ compare timing
→ compare freight and Incoterms
→ document discounts
→ propose justified adjustments
→ check whether lower qualifying comparables exist
→ reconcile payments
→ challenge the additional assessment
→ challenge the penalty separately.
Potentially, where the statutory conditions for the identical- or similar-goods valuation method are satisfied. But transaction value must first be considered under the required sequential valuation framework.
No. The comparison must comply with the applicable valuation method. Quantity, commercial level, timing, transportation and the characteristics of the goods can be highly important.
That can be highly relevant. Official guidance provides for adjustments where comparable transactions involve different quantities, provided the adjustment is supported by appropriate evidence.
The importer should challenge whether it qualifies as identical or similar goods. Technical characteristics, function, quality, reputation and commercial interchangeability may all matter.
Official definitions of identical and similar goods require attention to production in the same country as the goods being valued.
Where several qualifying transaction values exist under the identical- or similar-goods method, official Ministry guidance states that the lowest is used for determining customs value.
Potentially. The buyer-seller relationship alone does not automatically justify rejection of transaction value; whether the relationship affected the price is central to the analysis.
No. Even the fall-back method cannot be based on arbitrary or fictitious values or a system automatically selecting the higher of two values.
Yes. The valuation adjustment and administrative penalty should be examined separately, including the legal basis and calculation of the penalty.
The importer should first challenge any unjustified rejection of transaction value. If Customs is entitled to use identical or similar goods, the importer should then test the comparable transaction line by line—product, manufacturer, origin, quantity, commercial level, timing, freight and discounts—and submit documented adjustments demonstrating why the higher figure should not be applied without modification.
