Can I still claim zero duty under a UK trade agreement if goods pass through a third country?
Goods that pass through a third country can still qualify for zero or reduced duty under a UK trade agreement. But if they are released into free circulation along the way, the preference is lost, whichever agreement you claim under. With more supply chains running through regional hubs in Rotterdam, Dubai or Singapore, this is one of the easiest ways to lose a duty saving without realising it.
What the rule says
Every UK preferential arrangement contains a rule on goods travelling via a third country. Newer agreements, such as the EU–UK Trade and Cooperation Agreement, the UK–Japan CEPA and CPTPP, call it non-alteration. Some older continuity agreements still use direct transport wording.
The substance is much the same. While in the third country, originating goods may only undergo:
- unloading and reloading
- storage
- splitting of a consignment
- labelling or marking required by the importing country
- operations needed to keep the goods in good condition
Most agreements also expect the goods to remain under customs control while they are there.
Why free circulation breaks the chain
Release for free circulation means the goods have been customs-cleared into the transit country's market. Duty and import VAT are settled there, and the goods are no longer under customs supervision.
From that moment the link between the original exporter and the UK importer is broken. The goods have entered another economy and could have been sold, mixed with other stock or substiuted. Customs in the UK can no longer be sure the goods arriving are the same goods that were exported. So the agreement treats them as having lost their originating status for that journey, even if nothing physical happened to them.
Where it goes wrong
In practice, this rarely happens on purpose. Typical cases include:
- EU distribution hubs. Japanese or Korean goods are cleared into the EU at a central warehouse, then a share is sent on to Great Britain. Those goods cannot use the UK–Japan or UK–Korea agreement.
- Stock held "just in case". A supplier clears goods into a local market to keep them available, then later sells some to a UK buyer.
- Paperwork by default. A forwarder in the transit country lodges a standard import declaration instead of placing the goods in a warehouse or transit procedure.
- Returned or redirected orders. Goods rejected by a customer in the transit country are re-sold to the UK.
What it costs
The goods pay the full UK Global Tariff rate on arrival. If preference was claimed anyway, the problem usually surfaces later, when HMRC verifies the claim.
HMRC can look back up to three years after import, so a routing issue can turn into a post-clerance demand for duty across many shipments, plus interest and possible penalties. A valid origin statement from the exporter does not cure it. The statement confirms where the goods were made, not how they travelled.
How to protect your claim
A few checks before goods leave the origin country go a long way:
- Ask about the route. Find out whether the goods will stop anywhere between the exporter and the UK, and for how long.
- Keep goods under customs control in transit. Use a customs warehouse, free zone or transit procedure, not a release for free circulation.
- Ask for a through transport document where possible, such as a through bill of lading or air waybill from origin to the UK.
- Collect evidence from the hub. Warehouse records or a customs document from the transit country showing the goods stayed under supervision and were not altered.
- Keep the evidence with the import file, ready for HMRC verification.
The bottom line
Origin is not only about where goods are made. It is also about the journey. Goods can pass through a third country, be stored there and even be split, but once they are released into free circulation, the preference is gone.
If your goods route through a hub, talk to us before the next shipment moves. Bright Customs can review your documents before lodgement and flag routing questions to raise with your supplier. Each agreement has its own wording, so the origin rules of the specific agreement and HMRC guidance remain the reference for any claim.
