The Turkey ↔ UK puzzle
Turkey has a unique customs position with the EU and the UK:
- EU Customs Union for industrial goods — Turkish industrial goods circulate inside the EU without paying customs duty, certified by the A.TR movement certificate.
- Outside the Common Transit Convention — Turkey is not a CTC contracting party. Transit declarations starting in Turkey do not flow as straightforwardly as, say, a Swiss → UK move.
- The UK is outside the EU customs territory — anything entering the UK is treated as a third-country import.
For a load of Turkish industrial goods bound for the UK, this means you typically need:
- An A.TR to enter the EU customs territory duty-free
- A T1 transit to cross the EU on the way to the UK
- A UK import declaration at the UK border (CDS)
- A GMR on GVMS for the physical truck movement into the UK
Get any of those wrong and the truck stops.
Step 1 — A.TR at the Turkish border
The A.TR movement certificate is issued by Turkish customs and certifies that the goods qualify for free circulation under the EU–Turkey Customs Union. It applies to most industrial products — agricultural goods and ECSC products follow different rules.
The A.TR is presented at the EU entry point (usually the Bulgarian border at Kapıkule or sometimes Romania) and is the basis on which the EU office accepts that no duty is payable on entry.
Step 2 — Switching from A.TR to T1
The A.TR by itself does not carry the goods across the EU under customs control. For that you need a T1, lodged on NCTS at the EU office of departure. There are two common patterns:
- A.TR + T1 at the Bulgarian border — Turkish broker presents the A.TR and the EU broker lodges the T1 at the same office. The T1 then runs through the EU to the UK exit point.
- A.TR cleared in EU + T1 from inland — goods are released into free circulation at an EU customs warehouse on the strength of the A.TR, then re-exported on a T1 to the UK.
The first pattern is the most common for direct Turkey → UK lorries via the Bulkan route through Bulgaria, Romania, Hungary, Germany / Netherlands / France and on to the UK.
Step 3 — UK arrival and the T1 closure
When the truck reaches the UK port (typically Dover or Eurotunnel), the T1 needs to be closed at a UK office of destination. The driver presents the TAD; UK customs scan the MRN and confirm arrival in NCTS.
In parallel, the CDS import declaration is lodged either by the importer or their broker. The CDS entry covers the UK customs duty, VAT and any other UK import obligations. Once both the T1 is closed and the CDS entry is accepted (and duty is paid or deferred), the goods are released into UK free circulation.
Step 4 — GVMS at the UK port
For any RoRo port movement, a GMR is also required (see our GVMS and GMR guide). The GMR for a Turkey → UK movement typically attaches:
- The T1 MRN (transit closure)
- The CDS import MRN (UK import entry)
- The EXS / safety & security record if needed
The GMR is what the carrier checks at boarding. No GMR → no boarding.
Where things go wrong
- A.TR issued but no T1 prepared in time at the Bulgarian border → truck parked
- T1 office of destination wrong (e.g. set to Dover when the goods are unloaded in Tilbury) → discharge problems
- GMR built without the T1 attached → carrier refuses check-in
- CDS import entry not pre-lodged → goods released from transit but not from UK customs
A specialist broker who handles the whole chain — A.TR review, T1 lodgement, CDS import, GMR — keeps these things in sync.
