Turkish Customs Investigation for Sanctions Evasion: Criminal and Commercial Risks for Foreign Investors (2026 Updated Guide)

A foreign investor faces a Turkish customs investigation involving suspected sanctions evasion. Learn about shipment detention, false origin allegations, third-country routing, criminal exposure, company liability, bank restrictions and defense strategy.

A Turkish customs investigation involving suspected sanctions evasion can rapidly develop from a shipment-level compliance problem into a wider investigation affecting imported goods, company records, managers, bank transactions and future trade operations. Foreign investors may face particular scrutiny where transactions involve sanctioned or high-risk counterparties, third-country intermediaries, unusual shipping routes, dual-use products, disputed country-of-origin information, inconsistent customs documentation or payments that do not correspond clearly with the declared commercial structure. However, the existence of a complicated international supply chain does not by itself establish unlawful sanctions evasion. A proper defense requires the company to determine precisely which restriction is allegedly relevant, which transaction is under investigation, what conduct is attributed to the company and whether the evidence demonstrates intentional circumvention or merely a compliance or documentation problem.

What Can Trigger a Turkish Customs Sanctions Investigation?

A customs investigation may begin after authorities identify unusual characteristics in an import or export transaction. These may include third-country routing, discrepancies between invoices and shipping documents, changes in supplier identity, unexplained intermediaries, inconsistent origin information, unusual payment structures, sensitive goods or links between transaction participants and persons subject to restrictive measures.

The presence of one risk indicator does not automatically establish an offense.

Identify the Exact Legal Basis First

“Sanctions” is not a single universal legal category. Different restrictions can arise from different legal instruments and can affect different persons, goods, destinations and transactions.

The company should therefore identify the precise legal measure allegedly violated rather than responding generally to an accusation of sanctions evasion.

Determine Which Transaction Is Under Investigation

Investigators may initially question one shipment while examining whether the same commercial structure was used historically.

The company should identify the customs declaration, invoice, purchase order, supplier, manufacturer, carrier, payment and goods involved in the specific allegation.

Shipment Through a Third Country Is Not Automatically Evasion

Modern international trade frequently involves distributors, logistics centers, free zones and regional trading companies.

Routing goods through a third country should not automatically be treated as proof that sanctions were circumvented. The important questions include why the route was used, who owned the goods, where they were manufactured and what happened to them during transit.

Country of Origin and Country of Dispatch Must Be Distinguished

A product may originate in one country, be sold by a company in another country and be shipped from a third jurisdiction.

These concepts should be separated carefully. Incorrectly treating the dispatch country as the manufacturing origin can distort the entire investigation.

Build a Complete Supply-Chain Map

Foreign investors should reconstruct the transaction from manufacturer to final destination. The map should identify the manufacturer, exporter, intermediary traders, warehouses, freight forwarders, carriers, importer and ultimate customer where relevant.

Each commercial and physical movement should be supported by records.

Preserve Contracts and Purchase Orders

Supply contracts, purchase orders, amendments and correspondence can establish the genuine commercial purpose of the transaction.

They can also show when each counterparty entered the transaction and whether later changes had legitimate commercial explanations.

Shipping Records Can Become Critical Evidence

Preserve bills of lading, road transport records, container numbers, seal information, warehouse records, delivery documents and customs transit documentation.

These records may demonstrate whether goods merely passed through another country or underwent another operation there.

Customs Origin Documents Must Be Reviewed

Certificates of origin, A.TR documents, EUR.1 certificates and other customs documents should be compared with the actual manufacturing and logistics chain.

Different customs documents serve different legal purposes. They should not be treated as interchangeable evidence of origin.

False Origin Allegations Can Increase Criminal Exposure

If investigators believe that origin documents were deliberately falsified to conceal the true source of goods, the case can become considerably more serious than an ordinary classification or documentation dispute.

The defense should determine who prepared the disputed document, what information was supplied to that person and whether company managers knew of any inaccuracy.

Supplier Statements Should Be Verified

A foreign supplier’s declaration that goods originate in a particular country should not be accepted blindly when substantial sanctions exposure exists.

Obtain manufacturing records, factory information and supporting origin evidence where necessary.

Manufacturer and Seller May Be Different Companies

The entity issuing the commercial invoice may not manufacture the product.

The company should explain this distinction clearly and preserve documentation identifying the actual factory.

Changes in Suppliers Require Explanation

A sudden move from direct purchases to purchases through an intermediary may attract scrutiny, particularly if it occurs after restrictions affecting the original supplier.

There may nevertheless be legitimate reasons such as financing, distribution restructuring or logistics. Those reasons should be documented contemporaneously.

Beneficial Ownership Can Become Important

Investigators and financial institutions may examine who ultimately owns or controls companies participating in the transaction.

Foreign investors should therefore maintain reliable corporate records concerning shareholders, controlling persons and relevant group relationships.

Screening Only the Company Name May Be Insufficient

A transaction can involve multiple parties beyond the direct contractual supplier. Depending on the risk profile, compliance procedures may need to consider relevant manufacturers, intermediaries, consignees and ownership or control relationships.

Preserve Sanctions-Screening Records

If the company conducted screening before the transaction, preserve the results, date of screening, databases used internally, escalation records and compliance approvals.

Contemporaneous compliance evidence can be significantly more persuasive than a screening exercise performed only after an investigation begins.

Do Not Rewrite Historical Compliance Records

Companies should never create retrospective screening records and present them as documents generated before the transaction.

Any investigation conducted after the event should be identified transparently as a subsequent review.

Goods Classification May Affect the Investigation

Determine the correct tariff classification and technical nature of the goods. Sensitive industrial equipment, electronic components or other products may be subject to controls that do not apply to ordinary commercial goods.

A classification error can therefore materially affect the legal analysis.

Dual-Use Concerns Require Separate Review

Where goods can potentially serve both civilian and sensitive applications, determine whether export-control or licensing requirements are implicated.

Sanctions compliance, export controls and customs classification may overlap but should not be treated as identical legal questions.

End-Use Documentation Can Be Important

For sensitive goods, investigators may examine the intended recipient and ultimate use.

Preserve end-user statements, customer contracts, technical specifications and other documentation demonstrating the commercial purpose of the transaction.

Payment Routes May Be Investigated

A transaction involving one supplier but payment to another company can attract scrutiny.

Prepare a clear explanation of why the payment structure was used and preserve agency agreements, assignment documents, financing arrangements or other supporting records.

Bank Records Should Be Reconciled With Customs Records

The amount paid, commercial invoice value, customs value and contractual price may differ for legitimate reasons, but those differences should be explainable.

Unexplained discrepancies can lead investigators to suspect hidden payments or counterparties.

Cryptocurrency or Informal Payments Can Create Additional Questions

Unusual payment methods may complicate the company’s ability to establish the commercial trail.

Preserve complete records demonstrating payer, recipient, amount, purpose and connection with the underlying transaction.

Banks May Freeze or Reject Related Transactions

A customs investigation can have consequences outside the customs process. Banks may conduct enhanced compliance reviews, delay transfers or refuse particular transactions according to their legal and internal compliance obligations.

The company should respond with a coherent transaction file rather than fragmented explanations.

Company Accounts May Face Wider Scrutiny

If investigators suspect that payments are connected with prohibited activity, bank transactions may become relevant evidence.

Corporate and personal funds should be clearly separated, and legitimate payment flows should be documented.

Can Imported Goods Be Detained?

Yes, goods can become subject to customs measures where authorities identify legal grounds requiring detention, examination or seizure.

The company should obtain the formal basis for the measure and determine whether the goods are merely held for examination or formally seized within a criminal process.

Detention and Criminal Seizure Are Not the Same

The procedural consequences can differ substantially.

The company should identify the authority responsible for the goods, the relevant decision and the legal mechanism under which physical control is being maintained.

Preserve the Condition of the Goods

Record quantity, serial numbers, container information and physical condition where possible.

This can become important if the investigation continues for months or goods deteriorate while held.

Can Company Computers and Records Be Examined?

Where a criminal investigation develops and the applicable procedural requirements are satisfied, investigators may seek corporate records and digital evidence.

The company should immediately implement a lawful document-preservation procedure.

Do Not Delete Emails After Learning of the Investigation

Deleting communications can create significant additional problems and destroy potentially exculpatory evidence.

Preserve emails, messaging records, contracts, invoices and internal approvals relevant to the transactions.

Internal Communications Can Help or Hurt the Defense

Messages may reveal why a third-country intermediary was selected, what managers knew about restrictions and whether compliance concerns were raised.

The defense should review communications in context rather than relying on isolated phrases.

Who Can Face Criminal Investigation?

Depending on the alleged conduct and applicable offense, investigators may examine individuals who participated in or authorized the transaction.

Being a shareholder, director or foreign investor does not by itself establish personal criminal liability.

Management Position Alone Should Not Determine Guilt

Individual responsibility should be assessed according to the person’s actual role, knowledge, conduct and involvement.

A director who had no involvement in customs operations should not automatically be treated as having committed an offense merely because of corporate title.

Local Managers May Also Be Investigated

Customs, logistics, purchasing and finance personnel can become relevant where they prepared declarations, communicated with suppliers or authorized payments.

The company should map decision-making responsibility accurately.

Foreign Managers Summoned in Turkey Should Prepare Carefully

A foreign manager asked to provide a statement should understand the allegation before giving substantive explanations.

Interpreter and defense rights should be addressed where applicable, and technical customs issues should be explained accurately.

Translation Accuracy Is Essential

Sanctions, customs and origin terminology can be technically complex.

A mistranslation concerning “manufacturer,” “exporter,” “origin,” “end user” or “beneficial owner” can materially alter the meaning of a statement.

Do Not Sign an Inaccurate Statement

A foreign manager should review the statement carefully and ensure that corrections or objections are recorded before signing where necessary.

An interpreter should not replace the role of defense counsel.

Administrative and Criminal Proceedings Can Run Simultaneously

A company can face customs assessments or penalties while individuals are investigated criminally.

These proceedings should be coordinated because an explanation submitted in one file can affect another.

Do Not Use Contradictory Defense Positions

For example, the company should not tell Customs that it knew nothing about the manufacturer while simultaneously telling a bank that it had completed extensive manufacturer due diligence unless the factual distinction is genuinely explainable.

Create a central factual chronology.

Additional Customs Duties May Be Assessed

If the investigation reveals incorrect origin, classification, customs value or another declaration issue, authorities may assess additional customs liabilities independently of the sanctions allegation.

Each assessment should be analyzed on its own legal basis.

Customs Penalties Require Separate Analysis

An additional customs debt does not automatically answer whether a penalty is legally justified.

The declaration error, company knowledge, applicable provision and procedural history should be examined separately.

Goods May Also Become Evidence

Where the products themselves are relevant to origin, classification or technical capability, investigators may preserve them as evidence.

Technical examination may therefore become an important part of the defense.

Independent Technical Experts Can Be Necessary

Engineers or industry specialists may help establish what the product actually is, how it was manufactured and whether it has the technical characteristics alleged by investigators.

Legal arguments should be supported by technical evidence where necessary.

Foreign Factory Evidence Can Be Decisive

Where the allegation concerns disguised origin, obtain factory production records, bills of materials, machinery information, purchase records and production schedules.

A simple certificate stating “Made in Country X” may be insufficient in a serious circumvention investigation.

Historical Transactions Should Be Reviewed Immediately

Once one transaction is questioned, identify earlier imports or exports involving the same supplier, product and route.

This does not mean that every historical transaction was unlawful. It allows the company to determine the actual scope of potential exposure.

Create a Shipment Matrix

For each relevant shipment, record the declaration date, product, tariff code, origin, supplier, manufacturer, route, importer, payment recipient and current status.

This can reveal whether the disputed structure was isolated or recurring.

Review Goods Already in Transit

If additional shipments are approaching Turkey, determine whether they involve the same risk factors.

Continuing identical transactions after receiving notice of an investigation can substantially increase commercial exposure.

Supplier Contracts Should Be Examined

Review representations concerning sanctions compliance, origin, export controls, end use, beneficial ownership and customs documentation.

The contract should also be checked for indemnification and cooperation obligations.

Foreign Supplier Liability May Arise

If a supplier concealed its sanctions status, falsified origin information or provided misleading documentation, the Turkish importer may have contractual claims.

Preserve communications showing what representations were made before the transaction.

Consider Formal Notice to the Supplier

Prompt notice can preserve contractual rights and compel cooperation with requests for factory, ownership or origin information.

The supplier should also be instructed to preserve relevant evidence.

Do Not Accept a New Explanation Without Verification

A supplier confronted with an investigation may suddenly provide a different origin story or identify another manufacturer.

Verify new explanations against contemporaneous documents before incorporating them into the defense.

Customs Brokers Should Be Included in the Evidence Review

Obtain the instructions given to the customs broker, documents received by the broker and communications concerning origin, classification and value.

This can establish what information was available when the declaration was prepared.

Freight Forwarders May Hold Important Evidence

Transport companies can possess booking information, container records, shipper details, transshipment data and delivery instructions.

Request preservation of relevant records quickly.

Can the Company Challenge Seizure or Other Measures?

Potentially. The appropriate remedy depends on whether the measure arises from customs administration, criminal procedure or another legal framework.

The company should obtain the formal decision rather than relying on informal statements from logistics providers.

Urgent Judicial Protection May Be Necessary

Where detention or another administrative measure threatens irreversible commercial consequences, available urgent remedies should be evaluated according to the legal basis and procedural stage.

Criminal seizure measures require analysis under the applicable criminal procedure.

Reputation and Banking Risk Should Be Managed

Even before a final legal determination, sanctions allegations can affect financing, suppliers, insurers and customers.

External communications should be accurate and coordinated with the legal defense.

Conduct a Privileged Internal Investigation Where Appropriate

For complex cases, the company should reconstruct what happened, who knew what and when, and whether compliance controls functioned properly.

The objective is to establish facts rather than produce a predetermined conclusion.

Do Not Destroy Adverse Evidence

An internal investigation may uncover problematic communications or documents.

They should be handled lawfully. Destruction or concealment can materially worsen the company’s position.

Separate Mistake From Deliberate Circumvention

A central defense issue is often whether the facts demonstrate intentional concealment or instead a genuine documentation, classification, origin or due-diligence failure.

The company’s historical conduct and compliance procedures can be important in making that distinction.

Strengthen Compliance Before Future Transactions

The investigation should trigger review of sanctions screening, beneficial-ownership checks, origin verification, supplier onboarding, end-use controls and escalation procedures.

Correcting weaknesses can reduce future exposure even while the existing investigation remains contested.

Immediate Defense Strategy

When a foreign investor becomes involved in a Turkish customs sanctions-evasion investigation, the company should immediately identify the exact legal restriction, obtain formal customs and criminal decisions, preserve all records, suspend questionable transactions where appropriate, map the entire supply chain, verify manufacturers and beneficial ownership, reconstruct shipping and payment routes, review origin and classification, preserve screening evidence, coordinate corporate and individual defenses, examine historical and in-transit shipments, and protect all available procedural remedies.

Frequently Asked Questions

Does using a third-country supplier automatically constitute sanctions evasion?

No. Third-country trading structures can have legitimate commercial purposes. The actual parties, ownership, origin, route and purpose of the transaction must be examined.

Can Turkish Customs detain goods because of suspected sanctions circumvention?

Goods may be detained or otherwise subjected to customs measures where the applicable legal requirements are satisfied. The formal basis should be obtained immediately.

Can company directors be investigated personally?

Potentially, depending on their alleged conduct, knowledge and involvement. Corporate position alone does not automatically establish criminal responsibility.

Can an incorrect country of origin create criminal exposure?

Potentially, particularly where investigators allege deliberate falsification or concealment. A genuine origin dispute should be distinguished from intentional deception.

Is an A.TR certificate enough to prove that goods are of European Union origin?

Not necessarily. Free-circulation documentation and country-of-origin analysis serve different purposes.

What should a company do with emails after an investigation begins?

Relevant records should be preserved. Documents should not be deleted, altered or retrospectively recreated.

Can bank payments also be affected?

Yes. Banks may separately review, delay or reject transactions based on applicable restrictions and their compliance assessment.

Can the Turkish importer claim against the foreign supplier?

Potentially, particularly if the supplier made false contractual representations concerning sanctions status, origin, ownership or regulatory compliance.

Should previous shipments be reviewed?

Yes. A targeted historical review helps determine whether the questioned transaction is isolated or part of a recurring structure.

What is the most important defense step?

Build a complete, document-supported chronology showing who manufactured the goods, who sold them, where they originated, how they moved, who received payment, who ultimately controlled the counterparties and what the company knew when the transaction was approved. A complicated international supply chain is not itself proof of sanctions evasion, but every material step should be capable of a coherent and verifiable explanation.
