What Happens If an Online Seller Declares a Lower Value on Your Package?
You purchase a product online for USD 1,000.
You pay the full USD 1,000 by credit card, bank transfer or another traceable payment method.
The foreign seller then writes “Value: USD 50” on the commercial invoice, shipping document or customs label without asking you.
When the package arrives in Turkey, Customs notices the discrepancy.
Who is responsible?
Is the buyer automatically guilty because the package was addressed to him?
Can Turkish Customs demand additional tax?
Can an administrative fine be imposed?
And, more seriously, can the case become a smuggling investigation under Law No. 5607?
The correct answer requires a distinction between customs liability and criminal liability.
A foreign seller’s unilateral false declaration does not automatically make the Turkish buyer criminally responsible. However, this does not mean that Customs must accept the artificially low value or that the buyer can automatically receive the goods by paying tax on the false amount.
The buyer’s knowledge, the actual amount paid, the documents submitted to Customs, the person legally making the customs declaration and whether there was an intentional attempt to reduce customs duties are all critical.
1. The Amount Written on the Package Is Not Necessarily the Customs Value
One of the biggest misconceptions in international online shopping is that Customs must accept whatever amount the seller writes on the parcel.
It does not.
Under Turkish customs valuation rules, the primary method for determining the customs value of imported goods is generally based on the transaction value.
The Ministry of Trade explains that this means the price actually paid or payable for goods sold for export to Turkey, subject to the adjustments required under the Customs Law.
Accordingly, if:
- the seller writes USD 50 on the package;
- you actually paid USD 1,000; and
- the payment can be established through reliable records,
the customs value does not automatically become USD 50.
The Ministry defines the “price actually paid or payable” as the total payments made or required to be made by the buyer to the seller or for the seller’s benefit.
Therefore, the true transaction should normally be the starting point.
2. Example: You Paid USD 1,000 but the Seller Declared USD 50
Assume that you purchase a camera from a foreign website.
Actual purchase price: USD 1,000
Amount charged to credit card: USD 1,000
Seller’s customs declaration: USD 50
Turkish Customs may request documents demonstrating the real transaction.
You should be able to produce, where available:
- the website order confirmation;
- commercial invoice;
- credit-card statement;
- bank-transfer record;
- online payment receipt;
- PayPal or equivalent electronic payment record;
- emails or messages exchanged with the seller; and
- the product listing showing its actual sale price.
If these documents establish that USD 1,000 was genuinely paid, the seller’s USD 50 declaration does not normally override the real transaction value.
Indeed, providing the genuine payment documents can be one of the buyer’s most important protections against an allegation that the buyer himself intentionally attempted to undervalue the goods.
3. Is the Buyer Automatically Responsible for the Seller’s False Declaration?
No — particularly in terms of criminal responsibility.
This distinction is fundamental.
Article 20 of the Turkish Criminal Code establishes the principle that criminal responsibility is personal: a person cannot be punished merely because another person committed an unlawful act.
Article 21 further provides that, as a general rule, an offence requires intent and defines intent as knowingly and willingly carrying out the elements of the criminal offence.
Therefore, suppose that:
- you ordered a product for USD 1,000;
- you never asked the seller to reduce the declared value;
- you did not know that the seller would declare USD 50;
- you possess genuine proof of the USD 1,000 payment; and
- when Customs asks for documentation, you immediately provide the true invoice and payment information.
The fact that the foreign seller independently entered a false value does not by itself prove that you committed a customs smuggling offence.
The buyer’s knowledge and conduct must be examined separately.
4. Customs Liability and Criminal Liability Are Not the Same Thing
This distinction is essential.
A buyer may not have committed a criminal offence but may nevertheless face a customs assessment based on the correct value.
For example:
Seller declares: USD 50
Buyer actually paid: USD 1,000
Even if the buyer proves that he did not know about the seller’s false declaration, Turkish Customs can still determine that the goods must be processed according to the USD 1,000 transaction rather than the USD 50 figure.
Therefore:
“I did not know about the false declaration”
may be extremely important for criminal responsibility.
But it does not necessarily mean:
“I only have to pay tax calculated on USD 50.”
Taxes are generally calculated according to the legally correct customs value.
5. The Buyer Should Distinguish the Seller’s Shipping Declaration from the Turkish Customs Declaration
Another important point is that there may be more than one “declaration” involved in an international shipment.
The foreign seller may complete:
- a commercial invoice;
- a CN22 or CN23 postal declaration;
- an airway bill;
- a shipping label; or
- information transmitted electronically to the courier.
These documents are not necessarily identical to the customs declaration ultimately submitted to Turkish Customs for release of the goods.
This distinction is particularly important when deciding who may be responsible for an incorrect customs declaration.
Turkish customs rules place legal importance on the declarant and the representation mechanism used during customs clearance.
The Ministry’s Customs Guide states that persons signing or making a customs declaration are responsible, for purposes of customs penalties, for the accuracy of the information in the declaration, the authenticity of the accompanying documents and compliance with the obligations of the relevant customs procedure.
Therefore, a lawyer examining such a case should ask:
Who actually made the Turkish customs declaration?
Was it the buyer?
Was it a courier acting on behalf of the buyer?
Was a customs broker involved?
Was the incorrect figure simply copied automatically from information supplied by the foreign seller?
These facts can materially affect the legal analysis.
6. A Major Change Took Effect on 1 February 2026
Online buyers in Turkey should also be aware of an important recent regulatory change.
The Ministry of Trade announced that, effective 1 February 2026, the use of the simplified customs declaration mechanism for products purchased through foreign e-commerce platforms was generally terminated, regardless of the value of the order.
Such goods are now, in principle, processed under the general import procedures, subject to the specific exceptions preserved by the legislation.
The Ministry currently explains that for non-commercial goods for personal use arriving by post or express cargo with a value between EUR 0 and EUR 1,500 and a gross weight not exceeding 30 kilograms, express cargo operators may process the shipment by submitting a detailed declaration on the recipient’s behalf. Import duties and other applicable obligations must then be fulfilled.
Accordingly, old internet advice suggesting that low-value online orders automatically pass through Turkish Customs under a simple fixed-tax e-commerce regime may now be outdated.
7. Why Credit-Card, Bank and PayPal Records Matter
Payment evidence is especially important in an undervaluation dispute.
Suppose Customs asks:
“The seller says the product cost USD 50. How much did you actually pay?”
If you can produce a credit-card statement showing USD 1,000, that record strongly supports the real transaction value.
The Ministry expressly states that the relevant customs valuation concept concerns the amounts actually paid or payable by the buyer to the seller or for the seller’s benefit.
Accordingly, useful evidence may include:
Credit-card records:
A transaction showing payment to the online seller.
Bank records:
SWIFT, wire-transfer or account statements.
Electronic payment records:
PayPal or another payment-provider receipt.
Platform records:
The order-history page showing the purchase price.
Emails and messages:
Correspondence concerning price and payment.
Order confirmation:
A document showing model, quantity and price.
These documents are useful not only for valuation.
They may also demonstrate that the buyer never attempted to conceal the real amount.
8. What If Customs Believes the Declared Value Is Too Low?
Customs is not required to blindly accept an invoice or shipping document.
Turkish Customs is entitled to verify the accuracy of customs declarations.
The Ministry’s Customs Guide expressly states that customs authorities may verify the correctness of information contained in customs declarations and inspect the relevant goods where necessary.
Accordingly, Customs may compare the declaration with:
- payment documents;
- seller invoices;
- online product listings;
- model numbers;
- identical or similar merchandise;
- bank records; and
- other relevant transaction documents.
If the authority determines that the customs value was understated, the customs value can be recalculated according to the Customs Law.
9. Can Customs Demand the Missing Taxes?
Yes.
If the legally correct customs value is higher than the amount originally declared, any customs duties and other import taxes calculated on the understated amount may be reassessed.
For example:
Actual value: USD 2,000
Declared value: USD 200
If Customs determines that USD 2,000 is the legally correct customs value, the tax calculation may be reconstructed accordingly.
The fact that the seller entered the incorrect amount does not create a right to import the product using an artificially low tax base.
10. Can an Administrative Fine Also Be Imposed?
Potentially, yes.
Article 234/1-b of Customs Law No. 4458 contains an important penalty rule concerning understated customs value.
According to the Ministry of Trade, where goods subject to import duties based on value have a declared value lower than the value determined under Articles 23–31 of the Customs Law, Customs collects:
the additional import duties resulting from the difference, plus an administrative fine equal to three times the tax difference.
For certain limited differences or calculation errors, a different penalty mechanism may apply.
However, this should not be simplified into the statement:
“Whenever the foreign seller writes the wrong number, the Turkish buyer automatically receives a three-times fine.”
The legal position must be evaluated according to:
- who made the customs declaration;
- whose name the declaration was made in;
- the form of representation;
- what information the buyer supplied;
- whether the buyer corrected the value;
- when the discrepancy was discovered; and
- the precise customs procedure applied.
These details are particularly important where a courier or customs representative has processed the shipment using information supplied by the foreign seller.
11. What If the Buyer Did Not Know About the False Value?
This is one of the strongest distinctions in the buyer’s favour.
Consider the following scenario:
The buyer orders a laptop for USD 1,200.
The seller independently writes USD 100 on the parcel because it routinely undervalues international packages.
The buyer never requested this.
Customs contacts the buyer before release.
The buyer immediately submits:
- the USD 1,200 invoice;
- the credit-card record;
- order confirmation; and
- correspondence with the seller.
In such a situation, there is strong evidence that the buyer was not attempting to mislead Customs.
The buyer may still be required to complete the customs procedure and pay whatever taxes are legally due on the correct value.
But criminal responsibility cannot properly be inferred solely from the seller’s unilateral act.
Under Turkish criminal law, responsibility is personal and, as a general rule, criminal intent must be established.
12. What If the Buyer Asked the Seller to Declare a Lower Value?
The legal position changes dramatically.
Suppose the buyer sends the seller a message saying:
“Please declare the package as USD 50 so I do not have to pay customs tax in Turkey.”
The product actually costs USD 1,000.
The seller follows that instruction.
This is no longer merely a case of a foreign seller independently making a mistake.
The message may constitute strong evidence that the buyer:
- knew the true value;
- knew a lower value would be declared;
- specifically requested the false declaration; and
- intended to reduce the customs duties payable in Turkey.
This creates a substantially higher risk of both administrative and criminal consequences.
13. When Can the Matter Become a Smuggling Investigation?
The critical criminal provision is Article 3/2 of Law No. 5607 on Combating Smuggling.
The provision criminalises bringing goods into the country through deceptive acts or conduct so that customs duties are partially or completely unpaid. The statutory penalty is imprisonment and a judicial fine.
A deliberately falsified customs value can therefore become far more serious than an ordinary valuation dispute if it forms part of deceptive conduct aimed at avoiding customs duties.
However, not every incorrect value written on a parcel automatically constitutes the offence.
The criminal investigation must focus on issues such as:
- Who created the false document?
- Who knew it was false?
- Did the buyer request the undervaluation?
- Did the buyer submit or rely on the false document?
- Did the buyer conceal the actual payment?
- Were false invoices created?
- Were messages exchanged concerning tax avoidance?
- Was the purpose to reduce customs duties?
These factual questions are often decisive.
14. Seller Error Is Different from Buyer Participation
The following two situations should not be treated identically.
Situation A — Seller Acts Alone
Product price: EUR 800.
Seller declares: EUR 80.
Buyer paid EUR 800 and never requested undervaluation.
Buyer provides the genuine invoice and bank record when Customs asks.
Here, the buyer has a strong argument that the false value was the seller’s unilateral act.
Situation B — Buyer and Seller Agree
Product price: EUR 800.
Buyer tells the seller:
“Invoice it as EUR 80 for Turkish Customs.”
Seller prepares an EUR 80 invoice.
Buyer submits or relies on that invoice during customs clearance.
Here, evidence exists of intentional participation in the false declaration.
The risk of a 5607 investigation is materially higher.
15. What If the Seller Sends Two Invoices?
This can create a particularly serious situation.
For example:
Real invoice: USD 3,000
Customs invoice: USD 300
If messages demonstrate that the USD 300 invoice was prepared solely to present to Customs, authorities may treat this as evidence of deliberate deception.
The issue then extends beyond simple valuation.
A deliberately manufactured false invoice may become relevant when determining whether there was an aldatıcı işlem ve davranış—a deceptive act or conduct—for the purposes of Law No. 5607.
The buyer’s involvement is therefore crucial.
16. “The Seller Did It Without Asking Me” Is a Defence That Should Be Supported by Evidence
Simply saying:
“I did not know.”
may not always be sufficient.
Where criminal or administrative proceedings arise, the buyer should preserve objective evidence.
Important evidence may include:
- the original online advertisement;
- purchase confirmation;
- actual invoice;
- credit-card statement;
- bank transaction;
- electronic payment record;
- WhatsApp messages;
- emails with the seller;
- marketplace communications;
- shipping confirmation; and
- correspondence with the courier after the package reached Turkey.
If those records show that the buyer paid the real price and never requested a false declaration, they may be central to the defence.
17. What Should You Do When the Courier Asks for an Invoice?
If the courier contacts you and requests proof of value, the legally safest approach is generally to submit the true purchase documentation.
For example, if:
- the parcel states EUR 40;
- you actually paid EUR 600,
you should not create or request another EUR 40 invoice merely to match the parcel.
Instead, the genuine EUR 600 purchase record should be produced.
Doing so helps separate the buyer’s conduct from the seller’s incorrect shipping declaration.
18. Can Customs Examine the Transaction After the Goods Are Delivered?
Yes.
A customs declaration is not necessarily beyond review simply because the goods have already been released.
Turkish customs legislation permits post-clearance controls to verify the accuracy of customs declarations and related commercial documents.
The Ministry emphasises that incorrect information discovered through customs control can result in sanctions under the customs legislation.
Accordingly, retaining transaction documents after delivery is advisable, particularly for valuable imports.
19. Example: USD 5,000 Product Declared as USD 500
Consider a more serious example.
A Turkish resident orders professional electronic equipment abroad for USD 5,000.
The seller marks the shipment as USD 500.
Scenario 1
The buyer:
- actually paid USD 5,000;
- did not request the false declaration;
- produces the USD 5,000 banking record immediately.
The customs value may be reassessed.
Taxes may become payable on the correct value.
Depending on how the customs declaration was submitted and the applicable provisions, administrative consequences may also need to be examined.
But there is no automatic basis for saying that the buyer committed smuggling simply because the seller wrote USD 500.
Scenario 2
The buyer sends an email before shipment:
“Declare it as USD 500 so I pay less tax.”
The seller issues a false invoice.
The buyer later presents that document to Customs while hiding the USD 5,000 transfer.
The situation is fundamentally different.
The facts may support an allegation that deceptive conduct was intentionally used to reduce customs duties and therefore justify examination under Article 3/2 of Law No. 5607.
20. Does a Genuine Bank Payment Protect the Buyer?
It can be extremely valuable evidence, but it is not an automatic immunity.
A genuine bank record can establish:
- the actual price;
- the recipient of the payment;
- the date of payment; and
- consistency with the online purchase.
More importantly, if the buyer voluntarily produces a payment record showing a price higher than the amount written on the parcel, that behaviour may strongly contradict an allegation that the buyer intended to conceal the true value.
Nevertheless, all evidence must be considered together.
21. What If the Seller Declared the Product as a “Gift”?
The same principle applies.
A foreign seller may mark a commercial online purchase as:
“Gift – Value USD 20.”
But the buyer actually purchased the product for USD 500.
Writing “gift” on the parcel does not make the transaction genuinely gratuitous.
The payment records show that there was a sale.
Similarly, postal and express-cargo goods should not be confused with the separate passenger gift exemption. The Ministry expressly states that the EUR 430 passenger gift allowance does not apply to goods arriving by post or express cargo.
22. The Most Important Question: What Did the Buyer Know?
In practice, this question may determine whether a straightforward customs valuation problem escalates into a criminal case.
The relevant evidence may establish one of three situations.
The buyer had no knowledge
The seller independently understated the value.
The buyer immediately discloses the true payment.
Criminal responsibility is much harder to establish.
The buyer discovered the mistake but tried to use it
The buyer noticed the USD 50 declaration although he paid USD 1,000 and intentionally continued to rely on the false value.
The risk increases.
The buyer requested the undervaluation
The buyer specifically instructed the seller to reduce the invoice or customs value.
This creates the highest risk because there may be direct evidence of intent to avoid customs duties.
Conclusion: Are You Responsible If the Foreign Seller Declares a Lower Value?
The answer is not automatically.
Turkish law requires several different questions to be separated.
First, Customs is not bound by the artificially low amount written on an international parcel. The customs value is principally connected to the price actually paid or payable, and genuine bank, credit-card and electronic-payment records may establish that amount.
Second, the customs authority may recalculate taxes using the correct value, and an understated customs declaration can potentially trigger the administrative penalty provisions of Article 234 of Customs Law No. 4458.
Third, criminal responsibility is separate. Turkish criminal law recognises personal criminal responsibility and generally requires intent. A buyer who never requested, knew of or participated in the foreign seller’s false declaration should not automatically be treated as having personally committed smuggling.
However, where evidence shows that the buyer instructed the seller to undervalue the goods, obtained a false customs invoice, concealed the real payment or knowingly used deceptive documentation to reduce customs duties, Article 3/2 of Law No. 5607 may become relevant.
For this reason, the most important practical rule is simple:
