Five years after the UK left the single market, transport from Poland runs stably, but under new rules: every shipment needs an export and an import declaration, the border crossing is registered with a GMR, BTOM sanitary controls have applied since 2024, and ENS safety declarations plus the EU EES biometrics since 2025. What has disappeared is the uncertainty of the first years: procedures are known and predictable.
Timeline: how we got to today
- 1 January 2021: the end of the transition period; the TCA gives zero tariffs, but only for goods meeting the rules of origin.
- 1 January 2022: full import declarations in GB and the start of GVMS with GMR numbers at crossings.
- 2022-2024: the old CHIEF customs system wound down and declarations moved to CDS.
- 31 January 2024: the BTOM border model introduces health certificates for medium-risk food from the EU.
- 30 April 2024: physical sanitary checks begin at border control posts.
- 31 January 2025: ENS safety and security declarations extend to EU imports into GB.
- 1 May 2025: the end of duty stamps on strong alcohol.
- 12 October 2025: the EU EES launches, with biometrics for non-EU drivers entering Schengen.
What has settled
First: clearance is routine, not an exception. A mature exporter holds EORI numbers on both sides, complete invoice data and an agency or a carrier with customs handling, and declarations take hours, not days. Second: the border runs on documents prepared in advance; a GMR without the full set of declarations will not let the truck through, as described in our article on the GVMS system. Third: the zero tariff under the TCA is not automatic, it requires documented origin of the goods, covered in our piece on the TCA rules of origin. Fourth: buffer warehouses on the UK side stopped being a luxury; separating the crossing from the local delivery absorbs inspections, storms and consignee slots.
What five years taught exporters
- Documents prepared before loading are cheaper than fixing errors at the border.
- Transit time is planned with a buffer for checks and the crossing, not to the hour.
- Groupage takes discipline from the whole group of shippers, because one gap holds everyone's truck.
- Rule changes have not stopped: whoever follows the announcements does not improvise in January.
What lies ahead
The direction is clear: further digitisation of the border and the closing of exceptions. The removal of the customs duty relief for consignments up to 135 GBP announced in November 2025 (due by March 2029 at the latest) will reshape e-commerce, and successive stages of digital border systems on both sides of the Channel will gradually replace paper. The foundation does not change though: complete data, correct classification and a partner who knows the procedures. The whole process is described in our guide to UK customs clearance.
Three myths that survived five years
- The trade agreement removes the paperwork. It removes the tariff for goods with properly documented origin, but it does not remove customs declarations. An export and an import declaration arise on every shipment, a single pallet included.
- A small consignment needs no clearance. The value of a consignment affects which simplifications are open and how much is payable, not whether a declaration is required at all. A pallet of samples travels with the same data set as a full load.
- A CMR note settles matters at the border. The CMR note documents the contract of carriage between consignor, carrier and consignee. The border asks for customs declarations and a GMR reference, and does not treat the consignment note as a substitute.
What genuinely changed in a shipper's daily work
The most noticeable change is not in the rules but in the data. An invoice that before 2021 was enough in shortened form must now carry a goods description good enough to classify against, the commodity code, country of origin, net and gross weight and the agreed delivery terms. Companies that rebuilt their systems so those fields are produced automatically when the sales document is raised stopped experiencing the border as a burden. Those still filling them in by hand on every shipment keep losing hours and making the small errors that come back as amended declarations and queries from the authorities.
