An undervalued invoice from Dubai or China: when Turkish customs issues a fine and when it opens a criminal file

Turkish customs law treats an understated value first as a revenue problem. Article 234/1-b of the Customs Law (Law 4458) says it in one sentence: where the declared value of goods liable to ad valorem import duty is found to be lower than the value determined under Articles 23 to 31, you pay the import duties on that shortfall and, separately, a fine of three times the duty difference. Nothing there asks what you intended.

Law 5607, the Anti-Smuggling Law, describes something much narrower. Article 3/2 punishes the person who brings goods into the country with import duties partly or wholly unpaid by means of deceptive acts and conduct. That phrase carries the whole distinction. A price that is simply lower than the administration's reference figure is a valuation dispute. A price propped up by an invoice that does not reflect what was actually paid, by a supplier that cannot be traced, or by a payment routed so that the real figure never reaches the file, is deception — and the range there is two to five years' imprisonment together with a judicial fine of up to ten thousand days.

It helps to see what sits on the other side of Article 3. Paragraph 1 covers goods brought into the country without being put through customs procedures at all: one to five years and a judicial fine of up to ten thousand days, increased by one third to one half where the goods entered away from a customs gate. Your consignment did none of that. It arrived at a gate, was declared and was cleared. So the question in your file is never whether you carried goods past customs. It is whether the document you handed across the counter was built to mislead.

If the administration treats the discrepancy as valuation, what reaches you is an additional assessment and a penalty decision. The arithmetic inside Article 234 is fixed.

Two clocks then start. Under Article 242 you have fifteen days from notification to object to the next higher customs authority, which must decide within thirty days; if the objection is refused, the administrative court of the place where the act was done hears the challenge. Alternatively Article 244 lets you ask for settlement, again within fifteen days of notification. A settlement request suspends the objection and litigation periods, and if settlement fails the remaining time resumes — topped up to five days where less than five were left. You cannot ask twice. What is settled is final: no litigation, no complaint, payment within one month of the record being served, and no separate prompt-payment discount under Article 17 of Law 5326.

Article 244/2 marks the crossing point in plain terms: where the act underlying the duty and the penalty is connected with a smuggling offence under Law 5607, the settlement route does not apply. Once a referral to the prosecutor is made, the negotiating table you were counting on is gone.

What produces that referral is not the size of the gap but what the file contains alongside it — a second set of invoices, an invoice altered after issue, payments to the supplier that exceed the declared figure, correspondence agreeing the number to be written, or an intermediary in a third country whose only function was the paperwork. Where forgery is part of it, Article 4/5 provides that a conviction for that offence is entered in addition. Where three or more people acted together the sentence is increased by half (Article 4/2); where the offence is committed within the activity of an organisation the sentence is increased twofold (Article 4/1) — the Turkish text reads iki kat artırılır, an increase of two times the sentence rather than a doubling; and where it was committed within the activity or for the benefit of a company, security measures specific to legal persons follow (Article 4/3).

The value of the goods then moves the range again. Under Article 3/23 the sentence is increased by half to one time where that value is excessive, reduced by up to one half where that value is light, and reduced down to one third of it — that is, by between one half and two thirds — where the value is very light. Article 3/22 removes the argument importers reach for most often: the acts in Article 3 are punished as completed even if they stopped at the attempt stage, so a declaration caught at the counter, with the container never released, is not a defence. And the buyer in Türkiye is not automatically outside the file: under Article 3/5 a person who did not take part in the import but knowingly buys, sells, transports or stores the goods commercially faces one to three years and a judicial fine of up to five thousand days. Once an indictment is accepted, the court sends a copy to the customs administration, which on application is admitted to the case as an intervener (Article 18) — so the revenue claim now sits inside the criminal trial. A criminal file also brings measures the administrative route never does, and for a foreign director the first of them is usually a travel ban imposed as a judicial control measure.

Two provisions reward moving early, and both are priced.

On the administrative side, Article 234/3 is the cheapest outcome available anywhere in this area: report the discrepancy before customs finds it and the fines above are charged at ten per cent. On the criminal side, Article 5/1 of Law 5607 provides that a participant who, before the authorities learn of the matter, tells the relevant authority about the act, the other participants and where the goods are held is not punished — provided that information leads to those people being caught or the goods being recovered. Once the authorities already know, full assistance in bringing the act to light reduces the sentence by two thirds.

After that, Article 5/2 turns on payment. Pay twice the customs-inclusive value of the goods to the Treasury — for imported goods that value is the CIF price plus customs duties, as Article 2/1-b defines it — and the sentence is reduced by half if payment is made before the investigation stage ends, or by one third if made during prosecution before judgment. The prosecutor is required to put this to you during the investigation, and if that was not done the judge must do it at trial. Article 5/3 closes the door for recidivists and for offences committed within the activity of an organisation.

Two practical points for a company based abroad. First, the money moves before the case does: transfers connected with the consignment are what draw account restrictions, and the pattern is set out at frozen accounts and economic crime files in Türkiye. Second, the administrative and criminal tracks run on separate calendars, and objecting to the assessment does not pause the investigation. If you are working out which track your file is on, and what the ranges and remedies look like across the whole of Law 5607, start from customs smuggling charges in Türkiye.
