Why Do Cu?

Turkish customs authorities conduct risk-based inspections to ensure compliance with customs legislation, product safety regulations, trade policies, and import restrictions.

Common causes of customs delays include:

• Incomplete customs documentation.
• Incorrect HS tariff classification.
• Customs valuation discrepancies.
• Missing import licenses.
• Incorrect certificates of origin.
• Product safety inspections.
• Laboratory testing requirements.
• Customs system inconsistencies.
• Physical inspections.
• Random customs controls.

Many of these issues can be identified before the shipment arrives in Turkey.

Prepare Complete Import Documentation

Accurate documentation is the foundation of efficient customs clearance.

Before shipment, verify that all required documents are complete, including:

• Commercial Invoice.
• Packing List.
• Bill of Lading or Air Waybill.
• Certificate of Origin.
• EUR.1 Movement Certificate where applicable.
• Insurance Certificate.
• Freight documentation.
• Purchase Agreement.
• Sales Contract.
• Import licenses where required.

All documents should contain consistent information regarding quantities, values, product descriptions, and shipment details.

Verify the Correct HS Tariff Classification

Incorrect tariff classification remains one of the leading causes of customs delays.

Importers should verify:

• Harmonized System (HS) Code.
• Technical product specifications.
• Customs tariff description.
• Applicable customs duties.
• Import restrictions.
• Licensing requirements.

Proper classification reduces both customs delays and post-clearance audit risks.

Confirm Customs Valuation Before Shipment

Customs valuation disputes frequently delay customs clearance.

Companies should ensure that the declared customs value properly reflects:

• Transaction value.
• Freight charges.
• Insurance costs.
• Packing expenses.
• Royalties where applicable.
• License fees.
• Assists supplied by the buyer.

Supporting documentation should be available before customs declaration.

Verify Country of Origin

Origin documentation should be reviewed carefully before export.

Incorrect or incomplete origin documents may delay customs clearance and eliminate preferential tariff treatment.

Importers should verify:

• Certificates of Origin.
• EUR.1 Certificates.
• Supplier declarations.
• Manufacturing records where necessary.

Origin compliance is particularly important under Turkey’s preferential trade agreements.

Determine Whether Import Licenses Are Required

Certain products require prior governmental approval before customs clearance.

These may include:

• Medical products.
• Food products.
• Chemicals.
• Agricultural goods.
• Cosmetics.
• Telecommunications equipment.
• Dual-use products.
• Certain industrial equipment.

Failure to obtain required approvals before shipment may result in significant delays.

Ensure Compliance with Product Safety Regulations

Imported products may be subject to market surveillance and product safety controls.

Authorities may verify compliance with:

• Technical regulations.
• CE marking requirements where applicable.
• Product labeling.
• Turkish language instructions.
• Safety certificates.
• Conformity assessments.

Non-compliant products may be detained until regulatory requirements are satisfied.

Coordinate With Your Customs Broker Early

Foreign companies should communicate with their licensed customs broker before the shipment arrives.

Early coordination allows the broker to:

• Review documentation.
• Identify missing information.
• Verify customs declarations.
• Confirm applicable duties.
• Prepare customs filings.
• Resolve issues before cargo arrival.

Advance preparation significantly accelerates customs clearance.

Monitor Port and Airport Logistics

Operational delays may also arise from logistical factors.

Importers should monitor:

• Port congestion.
• Airport cargo capacity.
• Container availability.
• Terminal operations.
• Public holidays.
• Weather conditions.
• Transportation schedules.

Careful logistics planning helps minimize unnecessary storage charges.

Maintain Accurate Customs Records

Companies should maintain organized customs records, including:

• Import declarations.
• Commercial invoices.
• Payment records.
• Accounting documentation.
• Shipping documents.
• Customs correspondence.
• Technical specifications.
• Product certificates.

Well-maintained records facilitate both customs clearance and future post-clearance audits.

Conduct Internal Customs Compliance Reviews

Regular compliance reviews help identify potential problems before customs authorities do.

Internal reviews should evaluate:

• HS classifications.
• Customs valuation.
• Origin documentation.
• Import procedures.
• Broker instructions.
• Employee training.
• Record retention policies.

Preventive compliance reduces the likelihood of shipment delays.

Respond Promptly to Customs Requests

If customs authorities request additional documentation or clarification, companies should respond without unnecessary delay.

Prompt cooperation often prevents:

• Extended cargo holds.
• Additional inspections.
• Storage charges.
• Administrative penalties.
• Supply chain disruptions.

Delays in responding may significantly increase overall import costs.

Why Professional Legal Assistance Is Important

Complex import transactions often involve multiple legal and regulatory requirements.

An experienced customs lawyer can:

• Review import documentation.
• Verify customs valuation.
• Confirm HS classifications.
• Assess origin compliance.
• Review import licensing requirements.
• Assist during customs inspections.
• Resolve customs disputes.
• Represent companies before customs authorities and the Tax Courts.

Professional legal advice before shipment frequently prevents costly delays after arrival.
