Can Turkish Customs Reject Your Invoice and Use an Internet Price Instead?

You buy a product abroad for USD 500.

You have a genuine invoice, a credit-card record showing the USD 500 payment and correspondence with the seller.

When the goods arrive in Turkey, Customs searches the product online and finds the same model advertised for USD 2,000.

Can Customs simply say:

“We do not accept your invoice. The internet price is USD 2,000, so we will calculate customs duties on USD 2,000.”

As a general rule, the answer is not that simple.

Turkish Customs has broad authority to investigate whether a declared customs value is genuine and accurate. It may request additional documents, examine comparable transactions and use external price information when evaluating whether an invoice is credible. However, Turkish customs valuation law does not establish a system in which an officer may arbitrarily disregard a genuine transaction price and replace it with the first retail price found on the internet.

The determination of customs value is governed by a legally prescribed sequence of valuation methods.

The Ministry of Trade confirms that six methods must be considered in order:

1. transaction value;
2. transaction value of identical goods;
3. transaction value of similar goods;
4. deductive value;
5. computed value; and
6. the fallback method.

As a rule, Customs cannot move to a later method while the value can still lawfully be determined under an earlier one.

Therefore, the real legal question is not:

“Did Customs find a higher price online?”

It is:

“Was there a lawful reason to reject the transaction value, and if so, which statutory valuation method was used afterwards?”

---

1. The Starting Point Is the Transaction Value

Under Turkish customs valuation rules, the primary method is the transaction value method.

The Ministry of Trade describes the transaction value as the price actually paid or payable for goods sold for export to Turkey, subject to the additions and adjustments required under the Customs Law.

For example:

Invoice: USD 500
Bank transfer: USD 500
Purchase agreement: USD 500
Seller confirmation: USD 500

If these documents reflect a genuine sale, the starting point is normally the USD 500 transaction price.

The fact that another website sells the same product for USD 1,500 or USD 2,000 does not by itself prove that the buyer actually paid USD 2,000.

A customs value and an internet retail price are therefore not necessarily the same thing.

---

2. Can Customs Question the Invoice?

Yes.

An invoice is important evidence, but it is not immune from examination.

Article 65 of the Customs Law allows customs authorities to examine declarations and supporting documents and to request further documents in order to verify the accuracy of the information submitted. The Ministry of Trade has also expressly stated that Customs may investigate the reality and accuracy of a declared customs value and request additional information and documents from the importer.

Accordingly, Customs may become suspicious where, for example:

• the declared price is dramatically below normal market levels;
• the payment documents do not correspond with the invoice;
• there are two different invoices;
• the buyer made additional payments to the seller;
• the seller and buyer are related;
• the seller appears not to exist;
• the product description is inconsistent with the invoice;
• the invoice appears altered or false; or
• the importer cannot explain an unusually low price.

The existence of a low price can therefore justify investigation.

But suspicion is not the same thing as a final customs value.

---

3. A Low Price Does Not Automatically Mean a False Invoice

Goods can legitimately be sold below ordinary retail prices.

For example, a product may have been:

• purchased during a clearance sale;
• bought from an outlet;
• sold as refurbished;
• damaged;
• discontinued;
• purchased second-hand;
• sold in bulk;
• bought under a wholesale agreement;
• subject to a promotional discount;
• sold as old inventory; or
• purchased through a private negotiated transaction.

Therefore, a Customs officer finding a higher price on the manufacturer’s website does not automatically establish that the lower invoice is false.

The importer should be given an opportunity to explain the commercial reason for the price difference.

The Ministry’s guidance on customs valuation specifically emphasises that where Customs doubts the accuracy or reality of the declared value, additional information and evidence should be requested and the importer’s explanations examined.

---

4. Customs Must Have a “Reasonable Doubt”

The legal concept of reasonable doubt concerning the truth or accuracy of the declared value is particularly important.

The Ministry of Trade refers to Article 44/5 of the Customs Regulation.

Where Customs doubts the declared value, it may request additional information and documentation.

If, after examining those materials, the reasonable doubt remains unresolved, Customs may conclude that the customs value cannot be determined under the transaction-value method.

However, the Ministry also states that before reaching its final decision, Customs should communicate the reasons for its continuing doubts to the importer and provide a reasonable opportunity to respond.

This means that the process should normally look like this:

Invoice submitted → Customs identifies a concrete doubt → additional documents requested → importer explains the price → Customs evaluates the explanation → if reasonable doubt remains, transaction value may be rejected.

It should not ordinarily be:

Invoice USD 500 → Google result USD 2,000 → invoice automatically ignored.

---

5. What Documents Can Prove That Your Invoice Is Genuine?

Where Customs questions a low invoice, documentary consistency becomes extremely important.

The importer may rely on documents such as:

• bank-transfer records;
• SWIFT documents;
• credit-card statements;
• PayPal or electronic-payment records;
• purchase agreements;
• order confirmations;
• seller correspondence;
• discount emails;
• promotional advertisements;
• product listings from the date of purchase;
• evidence showing that the item is second-hand;
• photographs showing damage or condition;
• warranty information;
• seller accounting records, where obtainable;
• export declarations from the country of origin; and
• transport and insurance documents.

A particularly strong case arises where the invoice price and independent payment records match.

For example:

Invoice: USD 600
Bank transfer: USD 600
Online order: USD 600
Seller email: “Your discounted price is USD 600.”

This evidentiary combination is considerably stronger than merely presenting a one-page invoice with no supporting payment record.

---

6. Can Customs Use an Internet Price to Create Suspicion?

Yes.

An internet price can potentially be relevant when Customs assesses whether a declared value appears realistic.

For example, if a brand-new current-model laptop is invoiced at USD 100 while the manufacturer’s website, authorised dealers and several other sources show prices around USD 2,000, Customs may reasonably investigate the declaration.

The Ministry recognises the use of reference-price information as a tool for examining the truth or accuracy of declared customs values. At the same time, its customs valuation guidance states that comparable values used for comparison do not automatically replace the transaction value.

Therefore, an online price may be:

evidence triggering an investigation,

but it is not automatically:

the legally determined customs value.

---

7. Can the Internet Price Directly Replace the Invoice?

Not merely because the internet price is higher.

This is one of the most important legal points.

If the transaction-value method is lawfully rejected, Customs must proceed through the statutory valuation methods in their prescribed sequence. The Ministry expressly states that one method cannot ordinarily be skipped in favour of a later method unless the preceding method cannot be applied.

Therefore, if Customs rejects the USD 500 invoice, the next question should not automatically be:

“What is Amazon charging today?”

Instead, Customs must consider whether there is a customs value for identical goods imported into Turkey at or around the relevant time.

If that method cannot be used, it moves to similar goods.

Only if those methods cannot be used does the process continue through the remaining statutory methods.

The Ministry has specifically referred to Danıştay case law confirming that Customs must first examine the transaction-value method and cannot move to a later method without explaining why the preceding method was unavailable.

---

8. What Is the “Identical Goods” Method?

If the transaction value cannot be accepted, the second method examines the transaction value of identical goods.

According to the Ministry of Trade, identical goods are goods produced in the same country that are the same in all material respects, including physical characteristics, quality and reputation, subject to minor differences in appearance.

The comparison must also take into account factors such as:

• time of export;
• commercial level;
• quantity;
• transport costs; and
• relevant commercial differences.

If several transaction values for identical goods exist, the Ministry states that the lowest applicable value is used for determining customs value under this method.

This is very different from simply selecting the highest advertised internet price.

---

9. What Is the “Similar Goods” Method?

If an identical-goods value cannot be established, Customs may examine similar goods.

Similar goods do not have to be identical.

They must, however, have sufficiently similar characteristics and components to perform the same functions and to be commercially interchangeable.

Quality, reputation and trademark can also be relevant in determining similarity.

Again, this requires a genuine customs valuation comparison.

For example, Customs cannot necessarily compare:

a refurbished two-year-old laptop

with

a brand-new current-generation laptop

without considering the differences.

Likewise, an unbranded product should not automatically be valued using the retail price of a premium branded product simply because the products look similar.

---

10. Retail Internet Price and Import Transaction Price Are Different Concepts

An internet price may represent a retail sale to an end consumer.

An import transaction may represent:

• wholesale trade;
• distributor pricing;
• bulk purchasing;
• manufacturer pricing;
• outlet pricing; or
• liquidation pricing.

These are not necessarily economically equivalent.

For example:

Manufacturer retail website price: USD 1,500

Distributor buys 500 units for: USD 700 each

The existence of the USD 1,500 retail price does not prove that the distributor’s USD 700 invoice is false.

Quantity and commercial level are expressly relevant when identical or similar goods are used for customs valuation, and adjustments must be supported by objective evidence.

---

11. The Date of the Internet Price Also Matters

Online prices change.

A website may show today’s price, while the imported goods may have been purchased several months earlier.

A Black Friday discount may no longer appear online.

A discontinued model may have been discounted before being removed from the seller’s website.

Currency exchange rates and promotional campaigns may also affect the transaction.

The customs valuation rules concerning identical and similar goods therefore focus on transactions occurring at the same or approximately the same time as the relevant importation.

Accordingly, a current online price may have limited evidentiary value when the transaction occurred under materially different conditions months earlier.

---

12. What If Customs Finds the Manufacturer’s Official Price?

An official manufacturer’s price is potentially stronger evidence than a random marketplace listing.

But it still does not automatically establish the customs value.

Suppose:

Official retail price: EUR 2,000
Invoice: EUR 1,200

The importer demonstrates that the goods were purchased from an authorised distributor during an end-of-season sale.

Bank records confirm payment of EUR 1,200.

In such a case, the EUR 2,000 manufacturer’s price may justify asking questions, but the importer has substantial evidence explaining why the actual transaction price was lower.

The legal question remains whether the declared price actually paid or payable satisfies the transaction-value requirements.

---

13. What If the Invoice Really Is False?

The situation changes completely where Customs obtains evidence showing that the invoice does not represent the genuine transaction.

The Ministry of Trade’s own customs valuation guidance refers to Danıştay decisions involving circumstances such as:

• the true purchase price being understated in the documentation;
• additional payments being made to the exporter outside the declared invoice;
• false invoices being submitted;
• the stated exporter not actually existing; and
• dual invoices being created.

In such circumstances, the declared transaction value may legitimately be rejected and the true customs value determined under the applicable legal rules.

Thus:

A low invoice is not automatically false.

But:

A proven false invoice does not bind Customs merely because it contains a printed price.

---

14. Example: A EUR 5,000 Watch Bought for EUR 3,000

Suppose a watch normally retails online for EUR 5,000.

The buyer purchases it during a genuine authorised-dealer sale for EUR 3,000.

The buyer has:

• a EUR 3,000 invoice;
• a EUR 3,000 credit-card payment;
• the dealer’s sale advertisement; and
• email correspondence confirming the discount.

Customs finds the manufacturer website showing EUR 5,000.

The manufacturer’s website can be considered when examining whether the declaration is credible.

However, the buyer has strong documentary evidence that the actual transaction value was EUR 3,000.

The mere existence of a higher retail price should not automatically replace the genuine transaction price without the transaction-value method first being lawfully rejected.

---

15. Example: A EUR 10,000 Product Invoiced at EUR 500

Now consider a different situation.

A product generally sells for around EUR 10,000.

The importer declares EUR 500.

The invoice contains no detailed product description.

The buyer cannot produce a bank transfer.

The seller refuses to confirm the transaction.

Customs discovers another invoice showing EUR 8,500 and evidence of an additional payment to the exporter.

Here, Customs has considerably stronger grounds for rejecting the EUR 500 transaction value.

The Ministry’s guidance expressly recognises situations involving undeclared additional payments and false invoices as circumstances supporting a different customs-value determination.

---

16. What Is the Deductive Value Method?

Where earlier methods cannot determine the value, the deductive method may become relevant.

Under the Ministry’s explanation, where the imported goods or identical or similar goods are sold in Turkey in the condition in which they were imported, the customs value may be derived from the unit price at which the greatest aggregate quantity is sold to unrelated persons in Turkey.

Certain amounts are then deducted, including specified commissions, profits, domestic transport and applicable duties and taxes.

This illustrates again why a simple Turkish internet retail price cannot automatically equal customs value.

Even where domestic selling prices are used in the valuation process, legally required deductions must be made.

---

17. What Is the Computed Value Method?

The computed-value method is based broadly on elements such as:

• production materials and manufacturing costs;
• profit and general expenses; and
• relevant transport and other costs.

The Ministry states that application of this method requires the necessary information and documents concerning production to be provided and capable of verification.

Because obtaining reliable foreign production-cost information can be difficult, this method may be less practical in many ordinary import disputes.

---

18. What Is the Fallback Method?

If the customs value cannot be established through the first five methods, the fallback method is used.

Even then, Customs does not receive unlimited freedom to invent a figure.

The Ministry states that the fallback method must be compatible with the principles and general provisions of the WTO Customs Valuation Agreement, Article VII of GATT and the customs-value provisions of the Customs Law and Customs Regulation.

Therefore, the final method is not:

“Customs can choose any reasonable-looking online price.”

It remains a legally structured valuation method.

---

19. Internet Advertisements Can Be Misleading

An importer facing an internet-price comparison should investigate exactly what Customs has found.

Important questions include:

Is it the same model?

Is it new or used?

Is it the same production year?

Does it include VAT?

Does the price include domestic shipping?

Is it a manufacturer’s suggested retail price?

Is it an actual completed-sale price or merely an asking price?

Is the seller in the same country?

Is the product authentic?

Is the quantity comparable?

Is the commercial level comparable?

A webpage showing that someone is asking USD 5,000 for an item does not necessarily prove that identical goods are actually being sold at USD 5,000.

This distinction can be particularly important for:

• luxury watches;
• designer bags;
• second-hand machinery;
• electronic equipment;
• collector’s items;
• art;
• spare parts; and
• discontinued products.

---

20. What Should You Do If Customs Rejects Your Invoice?

The first response should generally be evidentiary rather than merely argumentative.

The importer should request clarification of:

1. why the declared transaction value is considered unreliable;
2. what evidence creates the reasonable doubt;
3. what additional documents Customs requires;
4. whether the transaction-value method has formally been rejected;
5. which subsequent customs valuation method is being applied; and
6. what data was used to calculate the substitute value.

The importer should then submit all available evidence proving the real transaction.

The Ministry itself emphasises that where the transaction-value method is abandoned, the reasons should be clearly identified and the continuing doubts should be explained.

---

21. Customs Cannot Simply Skip the Valuation Methods

This principle is particularly important in litigation.

The Ministry of Trade expressly refers to Danıştay 7th Chamber, E.2005/4295, K.2006/2881, stating that the transaction-value method must first be considered and that Customs cannot proceed to a subsequent method without determining that the previous method cannot be used and explaining why.

Therefore, an additional customs assessment may be legally vulnerable where the administrative decision effectively states:

“The invoice was too low. We searched the internet and found a higher price.”

without demonstrating:

• why the invoice was unreliable;
• why the transaction-value method was rejected;
• why the identical-goods method could not be used;
• why the similar-goods method could not be used; and
• which statutory method ultimately produced the assessed value.

The methodology is as important as the final number.

---

22. Can You Object to Customs’ Valuation Decision?

Yes.

Customs-value determinations that produce additional customs duties, penalties or other administrative decisions may be challenged through the administrative objection procedure provided by Article 242 of Customs Law No. 4458.

The Ministry’s guidance states that customs taxes, penalties and administrative decisions must generally be challenged before the superior customs authority within 15 days from notification of the relevant decision.

For example, a decision issued by a customs directorate is generally challenged before the relevant Regional Directorate of Customs and Foreign Trade.

If the administrative objection is rejected, judicial review may then be sought before the competent administrative tax judiciary in accordance with the applicable procedural rules.

The objection should not simply state:

“The value is too high.”

It should attack the valuation methodology.

---

23. What Should Be Written in the Objection?

A strong customs-value objection may argue that:

• the invoice represents the genuine transaction;
• payment records confirm the invoice;
• Customs has not demonstrated objective grounds for rejecting the transaction value;
• the price difference has a legitimate commercial explanation;
• internet listings concern different quantities, conditions or commercial levels;
• advertised retail prices are not equivalent to the import transaction;
• Customs failed to follow the statutory sequence of valuation methods;
• identical or similar goods were incorrectly selected;
• necessary quantity or commercial-level adjustments were not made;
• the internet price relates to a different date or model; and
• the administration failed to explain how the final customs value was calculated.

Supporting documents should be attached wherever possible.

---

Conclusion: Can Turkish Customs Replace Your Invoice with an Internet Price?

Turkish Customs can investigate your invoice.

It can search market information.

It can examine comparable goods.

It can request bank and payment records.

And if reasonable doubts concerning the declared transaction value cannot be resolved, it may reject the transaction-value method.

But this does not mean that Customs has unrestricted authority to replace every low invoice with a higher internet retail price.

Turkish customs law establishes a hierarchy of six valuation methods, beginning with the actual transaction value. Each method must ordinarily be considered before moving to the next.

An internet price may help Customs identify an unusual declaration or support a valuation investigation. It may therefore be relevant evidence.

But the legally significant question remains:

Under which statutory customs valuation method was the final value determined?

If Customs simply abandons a genuine invoice and chooses an online retail price without adequately explaining why the transaction value was rejected and how the statutory valuation methods were applied, the resulting additional assessment may be open to serious legal challenge.
