Guides / Single pallet Poland to UK · Updated 30 September 2026

Sending one or two pallets from Poland to the UK

Who files the export and import declarations, who acts as importer, what your pallet network needs from you, and why small shipments get held.

This guide is also available in Polish.

A single pallet crosses the same customs border as a full lorry. The paperwork is lighter in volume, but the steps are the same: the goods leave the EU customs territory under an export declaration, and they enter Great Britain under an import declaration. The difference for a small sender is that you are usually one of many customers on a pallet network or groupage trailer, so a missing document on your pallet can hold your goods while the rest of the trailer moves on.

Two declarations, two sides of the border

Every commercial pallet from Poland to England, Scotland or Wales needs two separate customs declarations.

• The EU export declaration. The European Commission explains that the exporter or declarant lodges it in the Automated Export System, normally at the customs office responsible for the place where the exporter is established or where the goods are packed or loaded. The goods are then presented at the customs office of exit, which checks them against the declaration and supervises their departure. Until they leave the EU customs territory, they stay under customs supervision.
• The UK import declaration. GOV.UK sets out that goods must be declared to UK customs on arrival, with the commodity code and the value of the goods, and that any duty and import VAT due must be accounted for. This is lodged in the Customs Declaration Service.

In practice, a Polish seller rarely files the export declaration personally; a Polish customs agency or the forwarder's broker usually does it. On the UK side, the importer can do it themselves or, as GOV.UK puts it, hire someone to deal with customs for them. Most small businesses use an agent.

Who is the importer?

This is the question that causes the most trouble with small shipments. The importer is the party that the UK import declaration is made for, and it needs an EORI number that starts with GB to import into Great Britain. Typically that is the UK buyer. If you are a Polish business selling on terms where you take care of UK clearance yourself, you would need to arrange a GB EORI and a UK declarant in your own name instead. Agree this in writing before the pallet is collected, because the forwarder cannot guess it. Our guide to Incoterms and who clears customs covers how the delivery terms decide it.

Direct or indirect representation

If a UK agent makes the declaration, you must give them written instructions, and those instructions must say whether they act directly or indirectly for you. Under direct representation the declaration is made in the importer's name and the importer is liable for it. Under indirect representation the agent acts in their own name and becomes jointly liable. GOV.UK is clear that appointing someone does not remove your own responsibility for due diligence on the declaration.

What the pallet network or forwarder needs from you

Pallet networks and groupage operators collect declarations data from every customer on the trailer. If yours arrives late or incomplete, your pallet is the one that stays behind. Before collection, have these ready:

• A commercial invoice showing seller, buyer, a clear description of each product, quantities and the value of the goods.
• The commodity code for each product line. GOV.UK notes that the code decides the rate of duty and whether an import licence is needed, so it is worth checking it yourself rather than leaving it blank. See our commodity code lookup guide.
• The importer's GB EORI number, plus whatever identifiers your Polish export agent asks for.
• A packing list with the number of packages, gross and net weights, and what is on each pallet.
• Written instructions naming the UK agent and the type of representation.
• Delivery terms stating who pays UK duty and import VAT.
• Any licence or certificate the goods need. GOV.UK asks importers to check whether their goods require one before they ship.

ISPM 15: the pallet itself is checked

Small senders often reuse whatever pallet is in the warehouse. That is risky. GOV.UK states that solid wood packaging material imported into Great Britain from any country must meet the ISPM 15 international standard. The wood must be debarked (small pieces of bark are tolerated within set limits) and treated, either by heat treatment to 56°C for at least 30 continuous minutes throughout the whole profile or by approved fumigation, and it must carry the ISPM 15 mark.

Any wood packaging may be checked at the border or at inland premises. If it does not comply, GOV.UK warns that it could be rejected or destroyed and you will need to make other arrangements to transport the goods. For a single pallet on a shared trailer, that means your goods are pulled off while everything else continues. For more detail, see our wood packaging guide, and the target page on marking and treating wooden pallets for export explains the stamp itself.

Typical reasons a pallet is held

From the requirements above, the usual problems on small consignments fall into a few groups:

1. No importer agreed. Nobody has a GB EORI or has instructed a UK declarant, so the import declaration cannot be made.
2. Missing or vague invoice. Descriptions such as "goods" or "parts" do not support a commodity code or a value.
3. Wrong or missing commodity code. The code drives duty and licensing, so an error can stop clearance or lead to a correction later.
4. Export not completed. Without an export declaration released in the EU, the goods have not properly left EU customs supervision.
5. Non-compliant wood packaging. Unmarked or untreated pallets can be rejected or destroyed.
6. Licence or certificate missing. Some goods need documents beyond the customs declaration.
7. Duty and VAT not arranged. If nobody has agreed who pays, or how import VAT will be accounted for, release can stall.

A short plan for your first pallet

Agree the delivery terms and the importer with your buyer. Confirm the commodity codes and write a proper invoice. Ask your forwarder exactly what data they need and by when, and who files the export declaration in Poland. Give written instructions to the UK agent. Check the pallet for the ISPM 15 mark. If you are unsure whether to use an agent at all, read do you need a customs broker.
