Facing a Turkish customs investigation after an anonymous complaint? Learn whether a complaint is enough for penalties, how customs inspections, searches and seizures work, and how importers and foreign companies can protect their rights.

A customs investigation can begin unexpectedly after a competitor, former employee, business partner, customer or another person reports suspected irregularities concerning a company’s imports. Turkey’s Ministry of Trade maintains mechanisms through which suspected smuggling activity can be reported to Customs Enforcement authorities, and the Ministry confirms that information concerning informants is protected under the Anti-Smuggling Law in applicable cases. For an importer, however, the existence of a complaint does not by itself prove that a customs violation or smuggling offense occurred. The authorities may use information received through a complaint as a starting point for examination, but any administrative penalty, additional customs assessment, search, seizure or criminal prosecution must ultimately rest on the applicable legal requirements and evidence. This distinction is particularly important in commercial disputes where anonymous or confidential complaints may be motivated by competition, employment conflicts or disagreements between shareholders. A company facing a customs investigation in Turkey in 2026 should therefore avoid focusing solely on discovering who complained. The more important questions are what conduct is being investigated, what evidence the authorities have obtained, which customs declarations are under review, whether the investigation is administrative or criminal, and whether any search or seizure measures have been lawfully authorized.

Can Someone Report a Company to Turkish Customs?

Yes. Suspected smuggling activities can be reported to Turkish Customs Enforcement.

The Ministry of Trade currently accepts smuggling reports through its Customs Enforcement reporting mechanisms, including the ALO 136 system and its reporting procedures. (muhafaza.ticaret.gov.tr)

A company should therefore assume that credible allegations concerning import practices can potentially lead to examination.

Can the Informant’s Identity Be Kept Confidential?

Yes, in relevant smuggling reports.

The Ministry of Trade states that under Article 19/4 of Anti-Smuggling Law No. 5607, the identity of persons reporting offenses covered by the relevant provisions cannot generally be disclosed without their permission unless the nature of the report itself constitutes an offense, and witness-protection provisions apply. (https://ticaret.gov.tr)

For the investigated company, this means that demanding the identity of the complainant may not be a productive first strategy.

Can a Complaint Trigger a Customs Investigation?

Yes.

Information received through a complaint may lead Customs Enforcement authorities to investigate the allegations and examine whether customs or anti-smuggling legislation has been violated.

The Ministry itself states that the time required to conclude a report varies according to the investigation, research and operational steps required and that no single completion period can be specified. (https://ticaret.gov.tr)

Does a Complaint Automatically Mean the Company Is Guilty?

No.

A complaint is an allegation.

Administrative and criminal consequences require the competent authorities to establish the relevant facts and legal basis.

The company should therefore distinguish the source of suspicion from the evidence ultimately used to establish liability.

Anonymous Allegation and Evidence Are Different

Suppose a complaint states:

“The company has been importing machinery under an incorrect GTIP code for three years to avoid customs duties.”

That statement may trigger examination.

It does not itself establish that the GTIP classification is incorrect.

The machinery must still be classified according to its objective technical characteristics and the applicable tariff rules.

Customs Investigations Are Increasingly Data-Driven

A complaint may not be the only source of scrutiny.

In July 2026, the Ministry of Trade reported that its post-clearance and secondary-control systems use advanced analytical mechanisms to identify risky companies and declarations. It reported TRY 8.3 billion in additional assessments and penalties from these controls during the first six months of 2026 alone. (https://ticaret.gov.tr)

This means an allegation may be compared with historical declarations and customs data rather than evaluated in isolation.

A Complaint Can Trigger Examination of Previous Imports

This is one of the greatest risks for established importers.

An allegation concerning one container may reveal a declaration practice used repeatedly for several years.

Customs authorities may therefore examine previous declarations where legally relevant.

Example: Repeated GTIP Classification

A foreign-owned company imports the same industrial component every month.

A complaint alleges that the company deliberately uses a lower-duty GTIP classification.

If customs examines the allegation and disagrees with the classification, the financial exposure may potentially extend beyond the latest shipment.

Immediately Audit Previous Declarations

The company should determine how many imports used the challenged classification.

This internal review should begin before management assumes that the investigation concerns only one transaction.

What Can Customs Investigate?

Depending on the allegation, authorities may examine GTIP classification, customs value, origin, quantity, import permits, product conformity, preferential treatment, exemptions, inward-processing transactions and other customs matters.

The precise scope depends on the suspected irregularity.

GTIP Complaints

Competitors sometimes possess detailed knowledge about imported products.

A complaint may allege that a company intentionally selected a tariff heading resulting in lower duties.

The company should prepare technical classification evidence immediately.

Product Documentation Is Essential

Useful materials may include technical specifications, catalogues, engineering drawings, photographs, chemical composition information, laboratory reports and manufacturer explanations.

Customs Value Complaints

An allegation may state that the importer is systematically declaring artificially low invoice values.

This can trigger examination of commercial transactions and payment records.

Reconstruct the Actual Transaction

The company should collect:

purchase agreement → purchase order → commercial invoice → bank transfer → transportation documents → insurance → accounting entries.

These records can demonstrate whether the declared transaction was genuine.

Related-Party Imports

Transactions between affiliated foreign and Turkish companies can receive particular scrutiny where authorities question whether the relationship affected the declared customs value.

Commercial pricing evidence should therefore be preserved.

Origin Complaints

A complaint may allege that goods declared as originating in one country were actually manufactured elsewhere.

This can become particularly significant where origin affects customs treatment or trade-policy measures.

Preserve Manufacturing Evidence

Supplier records, factory documents, certificates and production information may be necessary to demonstrate actual origin.

Missing Permit Allegations

Authorities may receive information that an importer is bringing controlled products into Turkey without the necessary authorization.

The company should determine whether the relevant GTIP and product characteristics actually trigger the alleged permit requirement.

A Regulatory Dispute May Hide a Classification Dispute

Customs may claim that a permit was required only because it places the product under a different tariff heading.

The underlying classification issue should therefore be addressed first.

False Invoice Allegations

An informant may allege that the company uses two invoices: one reflecting the actual commercial price and another lower invoice for customs.

This is a serious allegation.

The company should preserve banking records, accounting systems, ERP data, purchase negotiations and correspondence demonstrating the actual transaction.

Do Not Alter Accounting Records

Once an investigation is known or reasonably anticipated, existing records should be preserved.

Backdating, replacing or manipulating commercial documents can substantially worsen the company’s position.

Can Customs Inspect the Company?

Depending on the legal mechanism involved, companies can face customs audits, post-clearance controls, document requests or more serious enforcement measures.

The nature of the inspection should be identified immediately.

Post-Clearance Control Is Particularly Important in 2026

The Ministry of Trade has emphasized continued post-clearance company audits and secondary review of customs declarations. It reported that risk analysis tools are being used to identify companies and declarations for further examination. (https://ticaret.gov.tr)

A company contacted after a complaint should therefore determine whether it is facing an ordinary administrative audit or an anti-smuggling investigation.

Administrative Audit and Criminal Investigation Are Different

This distinction affects almost everything.

An administrative examination may concern additional customs duties and monetary penalties.

A criminal investigation may involve prosecutors, searches, seizures and potential criminal liability under Anti-Smuggling Law No. 5607.

Ask Which Authority Is Handling the Matter

The company should identify whether the matter involves:

Customs Directorate;

Regional Customs authority;

Customs Enforcement;

Ministry inspectors;

a Public Prosecutor’s Office;

or a criminal court.

This information reveals the procedural stage.

Obtain the File Information

Where criminal proceedings exist, the company should identify the investigation number and prosecutor’s office.

Management should not rely solely on informal statements that “customs is investigating us.”

Can Customs Search Company Premises Because Someone Complained?

A complaint does not mean that authorities can disregard the legal requirements governing judicial searches.

Justice Ministry educational materials concerning CMK Article 116 explain that a judicial search of a suspect’s premises requires the statutory level of suspicion based on concrete evidence that the suspect may be found or evidence of the offense may be obtained there. (Rayp Adalet)

The legal authorization underlying a search should therefore be examined.

What Should the Company Do When Officials Arrive?

Management should remain cooperative while identifying the authority conducting the operation and obtaining or examining the relevant authorization and records.

Employees should not obstruct lawful official action.

At the same time, the company’s procedural rights should be protected.

Contact Legal Counsel Immediately

Where a search, seizure or criminal investigation is occurring, legal assistance should be obtained immediately.

The company’s response during the first hours can significantly affect later evidentiary disputes.

Do Not Instruct Employees to Delete Messages

This can create serious additional problems.

Relevant emails, WhatsApp communications, ERP records, invoices and customs documentation should be preserved.

Do Not Tell Employees What Story to Give

Employees should provide truthful information.

Attempting to coordinate false explanations can transform a customs compliance dispute into a significantly more serious situation.

Can Computers Be Examined?

Digital records can become relevant in criminal investigations subject to applicable criminal procedural requirements.

Companies should identify what devices, data and records are being requested or subjected to legal measures.

Preserve IT Logs

Where allegations concern invoices or customs documents, system logs may show when documents were created, changed and approved.

This can become valuable defense evidence.

Example: Alleged Fake Invoice

An anonymous complaint alleges that a company creates a low-value customs invoice after receiving the genuine invoice.

ERP records may demonstrate that only one invoice existed and that it was automatically recorded before shipment.

Digital evidence can therefore rebut the allegation.

Can Commercial Documents Be Seized?

Documents capable of serving as evidence can potentially become subject to seizure under criminal procedural rules where the legal requirements are met.

Justice Ministry materials explain that property and documents useful as evidence or potentially subject to forfeiture can generally be seized, while certain protected communications are subject to specific safeguards. (Eğitim Dairesi Başkanlığı)

Seizure Should Be Documented

The record should identify what was taken.

Justice Ministry guidance for law-enforcement practice states that seizure records should describe the type, quantity and distinguishing characteristics of seized items, as well as information concerning where, when, why and from whom they were taken. (OLTU ADLİYESİ)

Companies should preserve copies of relevant records.

Check the Inventory

If authorities seize 25 folders, three computers and two external drives, the company should know exactly what was removed.

Any discrepancy should be documented promptly.

Can Commercial Goods Be Seized?

Potentially, particularly where the goods themselves are considered evidence or potentially connected with an alleged customs offense.

Seizure does not automatically mean permanent forfeiture.

Seizure and Confiscation Are Different

Seizure is generally a protective measure during proceedings.

Permanent forfeiture requires a separate legal basis and determination.

Importers should not abandon ownership rights merely because goods have temporarily been seized.

Can the Company Request Return of Seized Goods?

Potentially, depending on the legal basis and whether continued retention remains necessary.

Where physical evidence has already been documented or sampled, the company can examine whether release is legally possible.

Commercial Harm Should Be Documented

Seized machinery may stop production.

Seized raw materials may prevent contractual deliveries.

Perishable products may deteriorate.

Seasonal goods may lose their market.

These consequences should be recorded from the first day.

Storage and Demurrage

A customs investigation can create substantial warehouse, port and container costs.

Every invoice should be preserved.

What Rights Does the Company Have During the Investigation?

The precise rights depend on whether the company itself, its managers or employees are suspects and on the procedural stage.

In a criminal investigation, defense rights become particularly important.

Right to Legal Assistance

A suspect has the right to legal assistance under Turkish criminal procedure.

Justice Ministry materials also recognize the protected nature of communications between a suspect or defendant and defense counsel under the applicable CMK framework. (Eğitim Dairesi Başkanlığı)

Managers Should Understand Their Individual Position

A company director may be called to provide information as a witness in one context or questioned as a suspect in another.

These positions are legally different.

The person should understand their procedural status before giving a detailed statement.

Company Position and Director Position May Differ

The company may argue that an incorrect declaration resulted from an employee or broker mistake.

A manager may separately need to establish that they neither knew about nor participated in the disputed conduct.

Corporate and individual defenses should therefore be coordinated carefully.

Being a Director Does Not Automatically Establish Criminal Liability

A person’s title alone does not prove that they prepared, approved or knew about every customs declaration.

Actual involvement must be examined.

Identify the Customs Workflow

The company should determine:

Who selected the GTIP?

Who provided the customs value?

Who checked origin?

Who obtained permits?

Who instructed the customs broker?

Who approved the declaration?

This internal map can be decisive.

Customs Broker Responsibility

Many import declarations are prepared through customs brokers.

If the complaint concerns inaccurate declaration information, correspondence with the broker should be reviewed immediately.

Example: Broker Selected GTIP

The importer provides complete product specifications.

The broker independently selects the GTIP classification.

Years later, customs challenges that classification after a complaint.

Emails showing the technical information originally provided can become important evidence concerning both customs liability and individual criminal responsibility.

But the Broker Cannot Automatically Be Blamed

The company may have expressly instructed the broker to use a particular classification.

The documentary record should determine the defense.

Former Employee Complaints

A former customs manager or finance employee may possess detailed internal information.

Some allegations may be accurate; others may be exaggerated or motivated by an employment dispute.

The company’s response should focus on objective evidence.

Competitor Complaints

Competitors may understand pricing, suppliers and products well enough to make detailed allegations.

Again, motive alone does not prove the allegation false.

The strongest response is documentary and technical evidence.

Business Partner Disputes

A former distributor, shareholder or commercial partner may report alleged customs irregularities after a relationship deteriorates.

Commercial background can be relevant, but it should not replace substantive defense.

Should the Company Try to Discover the Complainant?

Usually this should not be the first priority.

The Ministry expressly protects informant identities in relevant Anti-Smuggling Law reports. (https://ticaret.gov.tr)

The immediate objective should instead be understanding and rebutting the allegation.

What If the Complaint Is Completely False?

The company should document why.

A false allegation may be disproved through customs declarations, technical reports, banking records, permits, accounting systems and supply-chain evidence.

False Complaint Does Not Automatically End the Investigation Immediately

Authorities may still need to verify the allegation.

The company should cooperate lawfully while protecting its rights and maintaining a written evidentiary record.

What If the Informant Fabricated Documents?

This materially changes the situation.

The company should preserve evidence demonstrating falsification and raise it through the appropriate procedural channel.

Do Not Contact or Threaten a Suspected Informant

This can create unnecessary legal risks and undermine the company’s position.

The investigation should be addressed through formal procedures.

Can Customs Examine Previous Years?

A complaint concerning current imports may lead authorities to examine historical transactions within the limits of the applicable customs and procedural rules.

Companies should therefore perform their own historical review.

Start With the Product Named in the Complaint

Identify every declaration involving the relevant product, supplier, GTIP and customs valuation method.

Then Look for Systemic Exposure

Determine whether the same practice affected other products.

A complaint about one product can reveal a broader compliance weakness.

Example: Royalty Payments

Suppose the complaint alleges that certain royalty payments were improperly excluded from customs value.

If the same commercial structure applies to hundreds of imports, the financial consequences can become substantial.

The company should investigate the entire structure rather than one declaration.

Internal Investigation Should Preserve Evidence

The company should create a controlled process for gathering records.

Documents should not be edited, overwritten or casually circulated.

Create a Master Customs File

The investigation file should contain:

customs declarations → invoices → payments → contracts → packing lists → bills of lading → origin documents → technical specifications → permits → broker correspondence → accounting records.

Build a Declaration Spreadsheet

For multiple shipments, management should compare:

declaration date → product → GTIP → customs value → origin → duties → broker → relevant permit → inspection result.

Patterns become easier to identify.

Technical Classification Review

Where the complaint concerns GTIP, obtain a product-by-product technical review.

A legal team cannot reliably resolve highly technical classification questions without appropriate product evidence.

Customs Value Review

Where valuation is challenged, reconcile every declaration with the company’s accounting and banking systems.

Any unexplained difference should be investigated internally before authorities ask about it.

Origin Review

Trace suppliers and manufacturing locations.

Do not assume the shipping country proves origin.

Permit Review

Determine whether every product had the required regulatory approvals at the relevant import date.

What If the Internal Investigation Finds a Genuine Error?

Do not conceal it.

The company should assess available correction, disclosure, settlement or other legal mechanisms according to the nature and stage of the matter.

Administrative Error and Intentional Smuggling Are Not the Same

A genuine classification mistake, calculation error or documentation misunderstanding should be distinguished from deliberate evasion.

Evidence showing how the mistake occurred can therefore be important.

Employee Training Records Can Help

If the company maintained written customs procedures and compliance training, these records can help demonstrate how the organization attempted to comply with customs requirements.

Compliance Policies Are Not Enough by Themselves

A company cannot rely on a policy manual if actual practices were different.

Authorities may examine what employees actually did.

Email Evidence Can Cut Both Ways

An email asking:

“Can we use another GTIP to reduce the duty?”

can become problematic depending on context.

An email asking an engineer to confirm the correct classification before declaration may support the company’s compliance position.

Do Not Explain Individual Emails Without Context

Long correspondence chains should be reviewed as a whole.

A single sentence can be misleading when separated from the surrounding discussion.

Can Customs Impose a Penalty Based Only on the Complaint?

A final customs penalty should have a legal and evidentiary basis establishing the relevant customs violation.

The importer should examine the inspection findings, calculations and evidence relied upon rather than treating the complaint itself as proof.

Request the Basis of Any Additional Assessment

If customs claims TRY 10 million in unpaid duties, the company should determine precisely how that figure was calculated.

Recalculate Everything Independently

Check:

declared value;

customs value;

duty rate;

GTIP;

quantity;

origin;

additional duties;

and penalty multiplier.

Calculation errors can occur even where some underlying customs adjustment is justified.

Administrative Objection Rights

If the investigation results in a customs assessment or administrative penalty, the importer should identify the applicable objection procedure and deadline immediately.

The notification date is critical.

Do Not Wait for the Criminal Investigation to Finish

An administrative customs deadline may continue independently from a criminal investigation.

The company may need to protect rights in both files simultaneously.

Customs Settlement May Also Need Evaluation

Where qualifying customs receivables and penalties are involved, the availability and strategic value of customs settlement should be assessed.

Settlement should not automatically be treated as the best solution where the underlying allegation is factually incorrect.

Criminal Proceedings Require Separate Strategy

If authorities believe the conduct constitutes an offense under Anti-Smuggling Law No. 5607, the company and relevant individuals may face a prosecutor’s investigation.

Administrative payment alone should not automatically be assumed to terminate that investigation.

Search and Seizure Should Be Reviewed Separately

Even where an investigation itself is legitimate, individual investigative measures must satisfy their own legal requirements.

The company should preserve every warrant, order and seizure record.

Digital Evidence

Customs investigations increasingly involve electronic evidence.

ERP systems, accounting software, email, cloud files and internal communications may provide the actual chronology of an import transaction.

Create Forensic Copies Where Appropriate

Where devices or records are central to a dispute, preservation of reliable copies can help the company defend itself later.

Never Modify Metadata Intentionally

Original timestamps and document history can become important evidence.

What If Company Servers Contain Unrelated Confidential Information?

The company should obtain legal advice concerning the scope of the authorized investigative measure and applicable protections.

A search involving customs documents should not be treated as permission for the company itself to destroy or conceal unrelated data.

Attorney-Client Communications Require Particular Care

Communications protected under applicable criminal procedural rules should be identified and handled appropriately.

Justice Ministry materials expressly recognize protections concerning defense counsel communications. (Eğitim Dairesi Başkanlığı)

Employees Should Receive Practical Instructions

Employees should be told to preserve documents, cooperate with lawful official requests, avoid speculation, avoid deleting communications and immediately forward official documents to the company’s legal team.

Public Statements Should Be Controlled

Companies sometimes respond emotionally to allegations by publishing statements accusing competitors or former employees.

That can create additional disputes.

Legal and public-relations responses should be coordinated.

Foreign Headquarters Should Be Informed Quickly

For multinational companies, delays between the Turkish subsidiary and overseas management can cause missed procedural deadlines.

A reporting protocol should be established immediately.

Foreign Directors Should Not Assume the Issue Is Minor

Turkey’s customs enforcement activity remains substantial. The Ministry reported that Customs Enforcement operations in January 2026 alone resulted in seizures valued at approximately TRY 7.655 billion. (https://ticaret.gov.tr)

Serious customs allegations should therefore be treated as genuine legal and operational risks.

Review Goods Already in Transit

If the complaint concerns a recurring import practice, shipments currently heading to Turkey should be identified.

Do not allow additional containers to arrive without evaluating whether they face the same issue.

Future Declarations Should Be Reviewed

The company should determine whether the disputed GTIP, valuation methodology, origin treatment or permit practice should continue.

Do Not Automatically Change Everything

An immediate change can itself create confusion if the original treatment was legally correct.

Obtain technical and legal analysis first.

Consider Binding or Preventive Customs Solutions for Future Imports

Where recurring classification uncertainty exists, the company should evaluate appropriate mechanisms to increase certainty for future customs transactions.

The objective is to prevent the same dispute from recurring.

Supplier Contracts Should Be Reviewed

If the allegation concerns inaccurate supplier information, contracts should determine responsibility for product descriptions, origin documents, invoices and regulatory compliance.

Customs Broker Contracts Should Also Be Reviewed

The company should identify the broker’s obligations and potential liability for professional mistakes.

Separate Government Liability From Commercial Liability

Even if customs lawfully assesses additional duties against the importer, the importer may potentially have a contractual claim against the party whose incorrect information caused the problem.

These are different legal relationships.

Can the Company Recover Damages From a Malicious Complainant?

Potential remedies depend heavily on the circumstances, evidence and nature of the conduct.

The company should not make this the primary objective while the customs investigation remains unresolved.

First establish that the customs allegation itself is unfounded.

Evidence of Commercial Damage

If an unlawful investigation measure causes goods to deteriorate, contracts to fail or production to stop, document those losses from the beginning.

Whether compensation is legally recoverable is a separate question.

Keep Storage Invoices

Where goods are detained, preserve storage, demurrage, detention and handling invoices.

Keep Customer Cancellation Records

If customers cancel orders because goods cannot be released, preserve the correspondence.

Keep Production Records

If machinery or raw materials are seized, document how production was affected.

The First 24 Hours After Learning About the Investigation

The company should identify the authority, determine whether the matter is administrative or criminal, preserve all relevant customs and electronic records, identify declarations potentially affected and notify appropriate legal counsel.

The First 72 Hours

Management should reconstruct the transactions named in the investigation, review GTIP, customs value, origin and permits, identify responsible employees and brokers, and determine whether goods, documents or accounts are subject to any protective measure.

The First Week

The company should conduct a broader historical customs review, obtain technical opinions where required, calculate potential financial exposure, protect administrative and criminal procedural deadlines and review shipments currently in transit.

What Companies Should Not Do

A company should not delete emails, replace invoices, backdate contracts, fabricate supplier explanations, pressure employees to provide coordinated false statements, threaten suspected informants or obstruct lawful investigative measures.

These actions can make the situation considerably worse.

2026 Legal Strategy After a Customs Complaint in Turkey

An importer or foreign-owned company facing a Turkish customs investigation after a complaint in 2026 should first identify the investigating authority and determine whether the matter is an administrative customs examination, post-clearance audit or criminal investigation under Anti-Smuggling Law No. 5607. The company should preserve the customs declarations, invoices, banking records, origin documentation, technical specifications, permits, broker correspondence and electronic communications relating to the allegation. It should then independently test every substantive issue raised—particularly GTIP classification, customs value, quantity, origin and regulatory authorization. If authorities conduct a search or seizure, the relevant authorization, scope and inventory should be documented and reviewed. If goods are seized, the company should evaluate whether continued retention is necessary and whether release can be requested. Management should simultaneously review previous declarations using the same customs treatment because a complaint concerning one shipment may expose a recurring practice. Administrative objection deadlines must be protected independently from any criminal investigation. The practical strategy is therefore: identify the investigation → determine whether it is administrative or criminal → preserve evidence → reconstruct the challenged transactions → verify GTIP, value, origin and permits → obtain technical expertise → review search and seizure measures → protect managers’ individual defense rights → audit historical declarations → review goods already in transit → calculate financial exposure → challenge unsupported assessments or penalties → seek release of seized goods → pursue appropriate administrative and criminal remedies.

Frequently Asked Questions

1. Can an anonymous or confidential complaint start a customs investigation in Turkey?

Yes. Information reported to Customs Enforcement can lead to examination or investigation. The complaint itself, however, should be distinguished from the evidence ultimately required to establish customs or criminal liability.

2. Can the importer learn who made the complaint?

Not necessarily. The Ministry of Trade confirms that informant identities receive statutory protection in relevant Anti-Smuggling Law reports. (https://ticaret.gov.tr)

3. Can customs fine a company merely because someone reported it?

A complaint may trigger scrutiny, but a customs assessment or penalty must ultimately have the necessary legal and factual basis. The company can challenge incorrect findings through the applicable procedures.

4. Can customs examine previous imports after receiving a complaint?

Potentially. Where the allegation concerns a recurring customs practice, historical declarations may become relevant. Companies should therefore conduct their own internal review promptly.

5. Can customs search a company’s office or warehouse?

Potentially, where the statutory requirements for the relevant search procedure are satisfied. In a criminal investigation, judicial search measures are governed by the applicable CMK requirements. (Rayp Adalet)

6. Can customs seize computers, documents or commercial goods?

Potentially, where the applicable legal conditions for seizure are satisfied. The company should obtain and preserve the relevant seizure documentation and inventory. (OLTU ADLİYESİ)

7. Does a customs investigation mean company directors will be prosecuted?

No. The investigation must establish the actual conduct and involvement of relevant individuals. Being a director or authorized signatory does not by itself demonstrate participation in an alleged customs offense.

8. What if the complaint was made by a competitor or former employee?

The complainant’s motive may provide context, but the strongest defense is objective evidence showing that the company’s customs declarations and import practices were lawful.

9. What if the company discovers a genuine customs error during its internal review?

The company should evaluate the nature of the error, affected declarations and available corrective or procedural options promptly. A genuine administrative error should not be concealed.

10. What should a foreign company do first after learning about a customs investigation?

Identify the investigating authority and file, preserve all customs and electronic evidence, determine whether the matter is administrative or criminal, reconstruct the challenged imports and immediately identify any objection, search, seizure or criminal-procedure deadlines.

Legal Support for Customs Investigations in Turkey

A complaint-triggered customs investigation can involve GTIP classification, customs valuation, origin verification, undeclared goods, missing import permits, post-clearance audits, Anti-Smuggling Law No. 5607 investigations, company searches, document seizures, commercial-goods seizures and potential customs penalties. The investigation may also expand from one shipment to historical declarations, making early internal review particularly important.
