UK customs and EU import: EAD, ENS, GMR, GVMS, CDS | OTSL

Customs to the United Kingdom and import into the EU are two different procedures that we run as part of transport. For export to the UK we prepare the EAD, file the ENS, create the GMR in the GVMS system and track the status in the UK CDS. For import we handle the EX/EAD on the export side, the French smart border with procedure 42, and veterinary and SIVEP controls.

Export to the United Kingdom, step by step

• The EAD, the export accompanying document, on the EU side.
• The ENS safety declaration and GB import readiness (ELO).
• The GMR created in the GVMS system, which the driver uses to cross the border.
• The UK CDS and its status messages, including CC529 and CC599, especially important for groupage loads with many declarations.
• T1 or T2 transit and the ATA (Admission Temporaire, the temporary admission document) carnet when goods return unchanged.

Why groupage is harder

On a groupage load one vehicle carries many shipments, and each has its own declaration. That is why CDS messages such as CC529 and CC599 must be watched for each consignment separately, so one missing status does not hold up the whole vehicle. We watch this for the client.

Import into the EU and controls

• The EX/EAD on the export side, import handling and the French ENS on the EU entry side.
• The French smart border at the Channel crossing, including procedure 42, an import clearance with deferred VAT.
• Veterinary and SIVEP controls for goods of animal and plant origin.
• Clearance of machinery and industrial loads, also at points in the Netherlands.

How do we work?

We have our own customs agencies in Poland and the UK and run clearance as part of transport, not a separate problem at the end. This is how our customs clearance service works. We say plainly who supplies which documents and watch the statuses on both sides of the border. We treat the client goods as our own.

What happens when the freight weight on the consignment note differs from the customs declaration?

When you prepare a T1 transit document for groupage freight, you must declare the exact gross mass of the goods. If the variance between the CMR (the Convention on the contract for international carriage of goods by road) consignment note weight and the physical weigh-in at the cross-dock depot exceeds 3% or 50 kg per pallet, border customs systems automatically route the declaration to a physical inspection channel. On a load of 26 pallets with a total weight exceeding 12,000 kg, a weight error on a single consignment blocks the Goods Movement Reference (GMR) generation for the entire vehicle.

Discharging the transit movement operates under strict time constraints. The customs office of destination typically allows an 8-day time limit to present the goods and discharge the T1 procedure after crossing the border. You have a window of 24 hours from registering the weight discrepancy to submit an amendment to the declaration in CDS to avoid holds at the inland border facility.

• Weight variances below 2% do not require an Export Accompanying Document (EAD) amendment, provided the tariff commodity code remains unchanged.
• Customs declaration updates must be completed within 4 hours of re-weighing to maintain the booked Eurotunnel or ferry sailing slot.

Note that this weight tolerance mechanism DOES NOT apply to excise goods, sanitary and phytosanitary (SPS) shipments requiring IPAFFS notifications, or ADR (the Accord governing international carriage of dangerous goods by road) dangerous goods. For these restricted commodity groups, any weight discrepancy exceeding 0.5% forces an immediate transport halt and full re-issuance of export documentation.

Step by step

1. Export documentation setup. You lodge the export declaration in the EU and receive the EAD document.
2. Safety declaration filing. You submit the ENS entry into the security system before border crossing.
3. GMR generation. You link the customs declaration references in the GVMS system to produce a single code for the driver.
4. Border transit. The driver presents the GMR code at the ferry port or Channel Tunnel terminal.
5. CDS status tracking. You monitor customs clearance updates in the CDS system until the cargo is released.

Definitions

• EAD (Export Accompanying Document): a document confirming the opening of the export customs procedure on the EU side.
• ENS (Entry Summary Declaration): a safety and security declaration submitted prior to arrival in the UK.
• GMR (Goods Movement Reference): a unique reference number linking all cargo declarations into a single border movement entry.
• GVMS (Goods Vehicle Movement Service): the UK IT system used to coordinate customs clearances at border crossings.
• CDS (Customs Declaration Service): the UK customs platform processing import and export declarations.

The OTSL role

If you are planning goods transit between Great Britain and the European Union, OTSL handles border formalities and freight execution. We coordinate groupage (LTL) transport while managing all EAD, GMR and CDS entries, and you can read our guide on safety and security ENS declarations for UK imports to understand entry requirements. With our warehouse in Milton Keynes and operations base in Kielce, we maintain full control over cargo clearance flows.
