Key Takeaways
- HMRC and Border Force can seize goods and vehicles where they believe customs or excise law makes them liable to forfeiture, so evidence needs to be available quickly.
- A notice of claim challenging the legality of a seizure must reach HMRC or Border Force within one calendar month, according to GOV.UK guidance.
- Restoration is separate from condemnation proceedings; you can ask for restoration even where you do not challenge the seizure as unlawful.
- Duty-paid evidence is strongest when it combines supplier onboarding, transaction records, logistics documents, payment trails and exception decisions.
- The B&M Retail tribunal decision shows that supplier assurances alone are weak, but proportionate due diligence and a clear decision trail can matter.
- Repeated detention or seizure should trigger a formal stop-trade review, not another undocumented commercial judgement.
Seizure Risk Is a Records Problem
Customs seizure risk becomes an operational problem the moment an officer asks how the goods entered the duty-paid supply chain. The legal basis matters, but the first practical question is usually simpler: can you show, from your own file, why you believed the goods were legitimate? If the answer depends on an upstream supplier finding documents later, your position is already weaker than it needs to be.
GOV.UK guidance says HMRC or Border Force may seize goods and vehicles under section 139 of the Customs and Excise Management Act 1979. Section 139(1) says anything liable to forfeiture under the customs and excise Acts may be seized or detained by an officer, constable, member of HM armed forces or coastguard.
That power reaches further than the border checkpoint. Excise goods, bonded movements, warehouse releases, diversion risk and missing provenance can all turn a routine stock movement into a seizure or penalty exposure. For an importer, wholesaler, retailer, 3PL or customs intermediary, your own records need to explain the commercial decision you made before accepting, storing, moving or selling the goods.
The same discipline supports wider customs compliance. A business that keeps clean packs for customs clearance and post-clearance audit evidence is better placed than one that treats seizure response as a legal exercise after the event. Duty-paid proof is a file that lets a reviewer follow the goods, money, checks and decisions.
The First Month Decides Your Options
The one-month deadline is the most dangerous part of a seizure response because it is easy to lose while you are still collecting documents. GOV.UK says a trader who disagrees with seizure has three options: challenge the lawfulness of the seizure by making a notice of claim, ask for restoration even if the seizure is accepted as legal, or do both. The notice of claim must be received within one calendar month of the seizure date or the notice of seizure date, and GOV.UK says there is no provision for late challenges.
That means the incident owner should separate process control from evidence gathering. The first job is to identify the seizure notice, the goods, the references, the deadline and the legal entity that owned the goods at the time. GOV.UK guidance says the claimant or solicitor must swear an oath at court that the claimant owned the item when it was seized. If ownership is unclear because of Incoterms, consignment stock, excise warehouse arrangements or agency purchasing, resolve that point immediately.
Condemnation and restoration should not be treated as the same route. Condemnation proceedings decide whether the seizure was lawful. Restoration is a separate request asking HMRC or Border Force to return the goods or vehicle, even where the seizure itself may be accepted.
The seizure file should be opened on day one with a short index. Record the notice date, seizure location, officer or team reference, goods description, quantities and brands, vehicle details, warehouse or movement reference, and the internal owner for the deadline. GOV.UK asks for clear reasons, full name and address, references, evidence of vehicle ownership where relevant, and specific quantities.
What Duty-Paid Evidence Should Contain
Duty-paid proof works best as a layered file, not as a single email from a supplier. Start with supplier onboarding. Keep the account application, company details, VAT and excise registrations where relevant, director or responsible-person checks, trade references, credit decision, bank verification and the reason the supplier was approved. If the supplier is new, offshore, recently incorporated, unusually cheap or operating through an unfamiliar route, record the extra checks you performed before trading.
The transaction pack should then connect the commercial bargain to the physical movement. It should include purchase orders, invoices, terms, duty or tax warranties, delivery notes, warehouse release records, transport instructions, batch or lot details, stock receipts and payment evidence. For alcohol, tobacco, energy products or other excise-sensitive goods, the file should explain how the goods moved from any duty-suspended or duty-paid environment into your control.
Pricing deserves its own note. A large unexplained discount is not proof of non-compliance, but it is a risk signal. Your file should show who reviewed the price, what benchmark was used, what explanation was obtained, and why the business still considered the transaction commercially rational.
Link the duty-paid file to your declaration and import records where the goods entered the UK through your own import process. If the transaction involved import VAT, tariff classification or a Customs Declaration Service entry, keep the declaration reference, import VAT evidence and any CDS declaration documents with the commercial pack.
Exception records are often the strongest evidence because they show the business was alert to risk. Keep a log of missing documents, late delivery notes, route changes, amended quantities, supplier reluctance, unusual payment requests and any detention or seizure history. Each exception should have a dated decision: accept, hold, escalate, reject or stop trading.
Lessons From B&M Retail v HMRC
The 2026 B&M Retail decision is useful because it shows how evidence may be assessed when absolute certainty is impossible. B&M Retail Ltd v HMRC [2026] UKFTT 1062 (TC) involved a Schedule 41 Finance Act 2008 penalty of £1,172,340.94 arising from B&M’s acquisition and possession of alcohol where HMRC could not establish that UK excise duty had been paid.
The First-tier Tribunal recorded that paragraph 4 of Schedule 41 FA 2008 can impose a penalty on a person who acquires possession of excise goods after the excise duty point where duty is outstanding and not deferred. The judgment also recorded the Upper Tribunal summary that HMRC can impose penalties on every person in a supply chain who has dealt with the goods, even if only one is assessed to duty.
The tribunal noted that CEMA 1979 section 154(2) applied to penalty proceedings, so it was for B&M to show excise duty had been paid on the beer and wine concerned. The Court of Appeal’s Euro Wines point, recorded in the judgment, was that traders are in a good position to carry out due diligence into the provenance of goods before acquiring dutiable goods. For operators, that is a warning against treating “we asked the supplier” as a complete answer.
B&M’s appeal was allowed because the tribunal found a reasonable excuse. The National Archives judgment records that the trader operated supplier onboarding procedures, transaction checks, pricing and supply explanation checks, and supplier assurances within a wider due diligence framework. The Bonded Warehousekeepers Association and RPC case report says the FTT accepted that B&M could not realistically obtain definitive proof of duty payment beyond the steps it had taken, and that HMRC itself could not establish whether duty had been paid because the upstream chain could not be traced.
The practical lesson is narrow but important. The case does not say supplier assurances are enough. It says a trader may be in a stronger position where it can show consistent, proportionate checks, rational escalation and records made before the dispute. Repeated detentions and seizures did not automatically prove non-payment on the evidence described in the case report; they showed HMRC could not verify the position. The commercial question was whether the trader responded proportionately as concern increased.
Escalation Triggers For Operators
Repeated detention is a formal escalation trigger, not routine friction. If the same supplier, product line, warehouse or route appears in more than one detention or seizure event, the file should move from transaction review to management review. Record who reviewed the pattern, what information was requested, what explanation was accepted or rejected, and what conditions were placed on further trade.
Unexplained price differences should also trigger escalation. For duty-sensitive goods, a low price can reflect a legitimate promotion, distressed stock, currency movement or volume deal. It can also indicate missing duty, circular trading or a supplier without proper control of the goods. Your record needs to show that the business noticed the signal and tested the explanation.
Missing upstream source information is another warning. A supplier may not be able to disclose every commercial detail, but refusal to identify the source of goods, warehouse of origin, duty status, route or release basis should be documented. If the supplier uses changing warehouses or relies on back-to-back paperwork without a clear stock trail, require stronger evidence before accepting further consignments.
Quantity and batch inconsistencies should be handled with the same seriousness as price anomalies. Differences between order quantities, delivery notes, stock receipts, excise documentation, warehouse releases and invoices can be innocent, but they make provenance harder to prove. Create a correction note, obtain revised documents where appropriate, and keep the reason for accepting the corrected position.
The final trigger is supplier behaviour after an incident. A supplier that responds quickly with consistent records is different from one that delays, changes explanations or asks you to proceed while paperwork is “being sorted”. The incident log should capture response times, missing documents, changed statements and any refusal to support a restoration or seizure challenge. Those entries may become central when HMRC asks why you continued trading after concerns emerged.
A Practical Records Checklist
Use a standard seizure-readiness checklist for any product line with customs, excise or regulated-goods exposure. The aim is not to create bureaucracy for every low-risk shipment. It is to ensure that higher-risk trades leave a record strong enough to explain your decision months later.
| Record area | What to keep | Why it matters |
|---|---|---|
| Supplier approval | Company checks, registrations, bank verification, references, approval note | Shows the supplier was assessed before trade started |
| Transaction file | PO, invoice, terms, duty warranties, payment trail | Connects the commercial bargain to your records |
| Movement evidence | Delivery note, transport document, warehouse release, stock receipt | Shows how the goods moved into your control |
| Duty and tax records | Import entry, excise movement evidence, VAT accounting, broker pack | Supports the duty-paid or properly declared position |
| Exception log | Missing documents, route changes, price anomalies, detention history | Shows risk signals were identified and managed |
| Decision record | Hold, release, escalate, stop-trade or legal review decision | Explains why the business acted as it did |
Assign ownership before an incident happens. One person should own the legal deadline, one should own the document pack, and one should own the commercial decision on whether trade continues. Customs records, excise records, VAT records, warehouse records and transport documents may sit in different systems, so a seizure file should link to the original records rather than rely only on copied PDFs.
Build the checklist into normal operations rather than waiting for HMRC contact. For importers, the same pack supports landed-cost control, import duty checks and customs broker oversight. For 3PLs and warehousekeepers, it helps distinguish client-owned compliance evidence from the operator’s own movement and storage records.
How To Respond After Seizure
Start with a short incident meeting on the day you receive the seizure notice. Confirm the legal entity, goods, owner, deadline, route, supplier, customer, warehouse, carrier and internal file location. Freeze relevant documents and tell commercial teams not to continue trading the affected line until the escalation owner has reviewed the evidence.
Create two parallel workstreams. The first protects the one-calendar-month notice-of-claim position if you intend to challenge the lawfulness of seizure. The second prepares a restoration request and commercial recovery plan. GOV.UK allows both routes.
Then test the duty-paid story from the outside. Ask whether a reviewer who does not know the supplier could follow the goods from order to receipt, link the commercial documents to the physical movement, see why the price made sense, and understand why the business accepted the supplier’s explanation. Where the answer is no, record the gap honestly and try to obtain primary evidence rather than more narrative.
Finally, decide whether the incident changes the trading relationship. A single document gap may justify a corrective action. Repeated seizures, unexplained source changes or a supplier that cannot support the chain should usually lead to suspension or exit. The decision should be dated, owned and kept with the file because HMRC may later ask why the business continued to trade after warning signs appeared.
Frequently Asked Questions
Can HMRC seize goods if duty might not have been paid? Yes. GOV.UK guidance refers to seizure powers under section 139 of the Customs and Excise Management Act 1979, and section 139 allows seizure or detention of things liable, or reasonably suspected to be liable, to forfeiture. The practical issue for the trader is whether it can show a credible duty-paid or compliant provenance file.
How long do I have to challenge a customs seizure? GOV.UK says a notice of claim challenging lawfulness must be received within one calendar month of the seizure date or notice of seizure date. The guidance says there is no provision for late challenges, so the deadline should be diarised immediately. Restoration can be requested separately, but it should not distract from the notice-of-claim deadline.
Is a supplier declaration enough to prove duty was paid? Usually not on its own. A supplier declaration is stronger when supported by onboarding checks, transaction records, warehouse and transport documents, payment evidence, pricing review and exception logs. The B&M Retail tribunal decision should not be read as approval for bare assurances; the accepted evidence sat inside a wider due diligence framework.
What records should a logistics provider keep if it does not own the goods? A logistics provider should keep movement instructions, collection and delivery evidence, warehouse receipt and release records, seal or batch information, client instructions, exception logs and incident communications. It may not hold the client’s full duty-paid evidence, but it should be able to prove what it did, when it did it, and what concerns were escalated.
Should I stop trading after a detention or seizure? You should at least run a documented escalation review before further trade. Repeated detentions, unexplained discounts, missing source information, supplier delays or inconsistent quantity records are strong reasons to pause until the evidence is resolved. If trading continues, record who approved that decision and why the remaining risk was considered acceptable.
