Discover the most important 2026 maritime law updates in Turkey affecting foreign shipping companies. Learn about Port State Control, environmental compliance, ship agency regulations, customs, taxation, sanctions, Turkish Straits navigation, and legal risks before entering Turkish waters.

Turkey remains one of the world’s most strategically important maritime jurisdictions, controlling access between the Black Sea and the Mediterranean through the Turkish Straits. Every year, more than 40,000 commercial vessels transit the Bosphorus and the Dardanelles, while thousands of additional ships call at Turkish commercial ports including Istanbul, Ambarlı, İzmir, Mersin, İskenderun, Gemlik, Tekirdağ, Samsun, Antalya, and Trabzon.

For foreign shipowners, operators, charterers, P&I Clubs, cargo interests, offshore contractors, and international investors, understanding Turkey’s evolving maritime regulatory framework is essential. Regulatory enforcement has become increasingly sophisticated, with greater emphasis on environmental protection, Port State Control (PSC), customs compliance, sanctions screening, digital reporting, and operational transparency.

Several important developments entered into force or were implemented during 2026, while international IMO amendments effective from 1 January 2026 also affect vessels calling at Turkish ports.

This 2026 Updated Legal Guide explains the principal legal developments foreign shipping companies should understand before entering Turkish waters.

---

1. New Ship Agency Regulation

One of the most significant domestic developments is the adoption of a new Ship Agencies Regulation, published on 14 May 2026, replacing the previous 2012 regulation.

The updated framework introduces revised authorization procedures, transitional rules for agency certificates, and a new five-year authorization period for newly issued certificates. Foreign shipping companies using Turkish ship agents should ensure that their appointed agents comply with the new regulatory requirements.

---

2. Increased Port State Control (PSC) Enforcement

Turkey continues to strengthen PSC inspections under both the:

• Mediterranean MoU
• Black Sea MoU

Inspection priorities include:

• SOLAS compliance.
• MARPOL compliance.
• ISM Code.
• ISPS Code.
• Ballast Water Management.
• Maritime Labour Convention (MLC).
• Crew certification.
• Safety management systems.

Repeated deficiencies increase the likelihood of vessel detention.

3. 2026 Concentrated Inspection Campaign (CIC)

Between 1 September and 30 November 2026, PSC authorities participating in the Paris, Tokyo, Mediterranean and Black Sea MoUs are conducting a Concentrated Inspection Campaign (CIC) focusing on Cargo Securing.

Foreign vessels calling at Turkish ports during this period should ensure:

• Cargo securing manuals are up to date.
• Cargo securing arrangements comply with SOLAS requirements.
• Crew members understand cargo securing procedures.
• Relevant documentation is readily available for inspection.

---

4. IMO Amendments Effective from 1 January 2026

Several important IMO amendments entered into force globally on 1 January 2026, including:

• Mandatory reporting of lost containers.
• Updated IMDG Code (Amendment 42-24).
• New STCW training requirements addressing bullying, harassment and violence at sea.
• Amendments affecting IGF Code and IGC Code compliance.
• Updates to fire safety systems for certain vessel categories.

These amendments apply internationally and are relevant during PSC inspections in Turkish ports.

5. Stronger Environmental Enforcement

Environmental enforcement remains one of Turkey’s highest maritime priorities.

Authorities continue to investigate:

• Oil pollution.
• Illegal waste discharge.
• Ballast water violations.
• Air emission compliance.
• Ship-generated waste.
• Sewage discharge.
• MARPOL recordkeeping.

Potential consequences include:

6. Digitalization of Maritime Administration

Turkey continues expanding digital maritime administration through systems supporting:

• Ship registry services.
• Ship agency procedures.
• Electronic certification.
• Survey processes.
• Bareboat registration procedures.
• Maritime reporting.

Foreign operators should ensure their documentation is compatible with current electronic procedures where applicable.

7. Customs Compliance Receives Greater Attention

Foreign vessels should carefully review:

• Dangerous goods documentation.

Recent industry discussions have highlighted increased scrutiny of declaration discrepancies, transit cargo inspections, and customs risk management.

---

8. Tax Planning Is More Important Than Ever

Foreign shipowners should evaluate:

• Permanent establishment (PE) risks.
• VAT treatment.
• Withholding tax.
• Double Taxation Agreements.

Early tax planning can significantly reduce future disputes.

9. Sanctions and Beneficial Ownership Screening

International shipping companies should strengthen due diligence regarding:

10. Ship Registration and Re-Flagging

Turkey continues to maintain strict requirements regarding:

• Turkish Ship Registry.
• Turkish International Ship Registry.
• Ship mortgages.
• Bareboat registration.
• Registry transfers.
• Technical inspections.

Foreign shipowners considering Turkish registration should begin legal planning well before the anticipated closing date.

---

11. Turkish Straits Navigation

Passage through the Turkish Straits remains governed by the Montreux Convention, while Turkey continues to regulate navigational safety through the Maritime Traffic Regulations for the Turkish Straits.

Shipowners should remember that freedom of passage does not eliminate compliance with navigational safety measures, traffic separation schemes, reporting requirements, and operational instructions issued by the competent authorities.

---

12. Stronger Corporate Compliance Expectations

Shipping companies operating in Turkey are increasingly expected to maintain effective compliance systems covering:

• Environmental compliance.
• PSC readiness.

Well-documented compliance programs often reduce regulatory exposure during investigations.
