Less-than-truckload (LTL) transport to the UK – customs challenges for groups [2026]

LTL (Less Than Truckload) transport, i.e. groupage, is the most popular shipping method for small and medium-sized companies. Your pallet travels on a trailer with 30 other pallets from different shippers. The cost is low because you share it with others. However, post-Brexit UK transport has introduced new risks: Collective responsibility.

The principle "One for all, all for one"

Imagine there are 20 shipments on the trailer.

• 19 shipments have perfect documents (invoices, HS codes, EORI).
• 1 shipment has an error (e.g. missing import licence, incorrect EORI code).

What happens at the border? The Customs Office detains the entire truck. No one will unload a trailer at the border lane searching for that one pallet. Your perfect shipment waits 2 days in Dover because someone else on the trailer (whom you don’t even know) filled in the paperwork incorrectly.

Customs issues in groupage

1. Multiple MRNs: The driver must carry customs declarations for every shipment. In GVMS, you may need to link, for example, 20 MRN numbers into one GMR. If one MRN is wrong, the GMR will not be generated and the vehicle will not board the ferry. 2. Clearance at different locations: You clear customs in Poznań, another sender in Warsaw, a third in Łódź. The driver travels from office to office collecting exemptions. This extends transit time (T/T). 3. Revision: If customs want to inspect a pallet that is "right against the wall" (at the front of the trailer), everything must be unloaded. Unloading costs and time are significant.

Small consignment clearance models

To minimise risk, logistics operators (such as Raben, DSV, Dachser or smaller freight forwarders) use various models:

Model 1: Consolidation in a warehouse (Hub)

Goods are consolidated in a warehouse in Poland. There, the customs agency either closes the whole vehicle under one summary model or ensures that each shipment has its own MRN. Only clean paperwork allows the vehicle to leave without further hold-ups. This is a safer model but extends time by 24 hours.

Model 2: Clearance on the move

The vehicle collects goods across Poland. Each sender handles its own customs clearance, which means the whole trip depends on every document being correct. The cheapest and fastest model, but the riskiest.

Model T1 (Transit)

The operator opens a transit procedure (T1) for the entire vehicle in Poland. Import clearance of all goods takes place only at the customs warehouse in the UK (inland).

• Plus: Fast border crossing (one T1 document).
• Minus: In the UK, vehicles must be dismantled in a customs warehouse and each package cleared separately.

How to secure your LTL shipment?

Unfortunately, you cannot control what others load onto the same vehicle. However, you can protect yourself: 1. Choose experienced freight forwarders. Those who verify documents before loading. 2. Submit documents in advance. Do not hand the invoice to the driver "at loading". Send it to the agency 2 days in advance. 3. Stay in touch. If the UK customs officer has questions, you must respond within 15 minutes to avoid blocking the vehicle.

In groupage transport to the UK, the cheapest option is not always the safest. Sometimes it is worth paying more for an operator with in-house customs support that screens problematic shipments before departure.
