Goods Detained at the UK Border – What to Do Next

Why HMRC and Border Force detain goods

Goods being detained at the UK border is not simply "bad luck". In 90% of cases a specific, technical reason can be identified — and in 80% of those cases it can be resolved within 24–72 hours, provided you know what to do. Since Brexit (January 2021) HMRC and Border Force have tightened controls, and the full rollout of the Border Target Operating Model in 2024 added mandatory SPS (sanitary and phytosanitary) checks for many categories.

The most common causes we encounter at Easy Clearance:

1. Missing or incorrect documents

Number one on the list. An invoice lacking required elements (Incoterms, HS code, country of origin, EORI), absence of EUR.1 certificate where preferential tariff treatment is declared, no CHED health certificate for animal and plant products, missing T1 transit MRN. In the CDS (Customs Declaration Service) system, any error in a Data Element triggers a "red" or "orange" routing requiring intervention.

2. Discrepancy between declaration and actual goods

A classic scenario: the declaration says "automotive parts" (CN code 8708) but the container holds lithium-ion batteries (CN code 8507 — dangerous goods, class UN3480). Or the CMR states 22 pallets but there are physically 24. An HMRC inspector treats any discrepancy as a potential misdeclaration — which carries the risk of a civil penalty of £250 to £2,500.

3. Risk-based targeting

The CDS system randomly directs 3–7% of shipments to inspection (the "red route"). This does not mean you have done anything wrong — but you must be prepared for a physical check. Risk increases for: first-time imports from a new supplier, unusual HS code/country of origin combinations, declared values that diverge from market benchmarks (HMRC market intelligence), importers with a low compliance history.

4. Prohibited or restricted goods

Counterfeit branded goods (Louis Vuitton, Nike — Border Force has a dedicated IPR unit), medicines without MHRA approval, food without PHA approval, CITES-regulated items (skins, ivory, certain timber), weapons and ammunition, dual-use goods without an export licence, goods from sanctioned countries (Russia, Belarus, Iran, North Korea). There is no "release" here — the outcome is seizure and criminal proceedings.

5. Undervaluation

HMRC holds reference value databases. If you declare 500 pairs of trainers at £2,000 (i.e. £4 per pair), the system will flag it. Understating value to reduce duty and VAT is a classic tactic — with serious consequences: from an amended entry with additional duty plus penalty, to seizure and criminal charges under the Fraud Act 2006.

The first 24 hours — what to do

Speed is everything. The faster you act, the lower the demurrage costs and the greater the chance of a straightforward resolution.

Hour 0–1: Gather information

• MRN / DUCR / EORI — reference numbers from the CDS system
• Port and terminal — Dover, Felixstowe, Southampton, London Gateway, Holyhead
• CDS status — "Route 1/2/3" (green/orange/red)
• Warehouse/terminal contact — who holds the goods and what they charge per day
• Formal notice from HMRC/Border Force — if received, scan it immediately

Hour 1–3: Contact your customs broker

If you have a broker — call them. If they are unavailable or "can't help" — that is a signal it is time for a second opinion. Easy Clearance handles emergency interventions for third-party clients on an hourly basis, with no long-term commitment required — often a single call to the HMRC helpline (0300 200 3700) or a correction to the declaration is enough to get the goods moving.

Hour 3–12: Gather additional documents

Depending on the reason: original commercial invoice, packing list, CMR, bill of lading, certificate of origin, EU exporter's statement on origin, CHED-A/P/PP/D, BTI (Binding Tariff Information), invoices from previous imports of the same goods (proof of market value), correspondence with the supplier. The most frequent "quick fixes" simply involve sending a missing document.

Hour 12–24: Operational decisions

If release looks likely to take more than 48 hours — arrange transfer to a bonded warehouse, release the driver, and plan a second transport run for collection. This is a purely economic decision: driver and tractor standstill costs versus warehouse costs plus a second delivery run.

Who is responsible — legally and financially

This is the question we hear most often from freight forwarders. The answer is straightforward:

• The importer of record (CDS declaration, Data Element 3/16) — ultimately responsible for duty, VAT, penalties and standstill costs. This is typically the UK-based consignee, but under DDP terms the EU supplier may also act as IOR.
• The customs broker/agent — acting as "direct representative", they bear no tax liability but are contractually liable to the client for professional errors. As "indirect representative" (less common) the agent becomes jointly and severally liable.
• The carrier — responsible for the physical safety of the goods, completeness of entry documents (T1, ENS, GMR) and port charges. Not responsible for errors in the import declaration.
• The freight forwarder — contractually, under BIFA/FIATA terms. Liability for customs errors is typically broadly excluded.

In practice: you pay first, then pursue recovery (if you have the paperwork). That is why, before signing a contract with a freight forwarder or broker, you should read the liability clauses — more in our article on UK customs penalties and civil penalties.

Standstill costs — what it really costs

Clients ask: "Right, it's sitting there. What does that cost me per day?" Real figures from our 2025–2026 practice:

On top of that: a civil penalty of £250–£2,500 if the inspector determines the error was culpable. And a surcharge for re-lodging the declaration. A typical 3-day detention at Felixstowe with physical inspection is realistically £800–£1,500. Seven days — £2,500–£5,000. After 14 days of standstill, costs can exceed the value of the goods themselves.

How to release detained goods — step by step

1. Identify the type of hold — inspection, detention or seizure? This determines the entire path forward. Check status in CDS or by contacting the port.
2. Formal notice from HMRC/Border Force — wait for the notice (BOR156, C155, C18 or similar). Without a notice you have no legal basis for responding. If nothing arrives within 48 hours — the customs agent sends a formal enquiry.
3. Respond with documents — submitted via CDS (correction entry), email to the local HMRC office or via the Notice 12A portal. Deadline: typically 14 days, but in practice the sooner the cheaper.
4. Payment of duty/VAT + any penalty — often a condition of release. Payment is made via a CHIEF/CDS deferment account or directly to HMRC.
5. Release note — HMRC issues a release in the system, the port physically releases the goods, the driver arrives for collection.
6. Cost recovery and appeal — if you believe the detention was unjustified, submit an appeal within 30 days (see below).

Seizure vs detention vs inspection — legal distinctions

The appeal process — Notice 12A and beyond

When HMRC or Border Force confiscate goods, you receive Notice 12A ("Seizure of Goods"). This is a formal notice setting out the legal basis (typically the Customs and Excise Management Act 1979, section 139) and your right to challenge the decision.

Three routes, which are not mutually exclusive:

• Notice of Claim (Schedule 3 CEMA) — you challenge the lawfulness of the seizure itself. Deadline: 30 days from Notice 12A. The case is decided by the Magistrates' Court or High Court (condemnation proceedings). If you win, the goods are returned.
• Restoration request — you ask HMRC to return the goods even if the seizure was lawful (e.g. "the error was unintentional, a financial penalty is sufficient"). HMRC has full discretion. Submit in writing to the UK Border Force National Post Seizure Unit.
• Appeal to the First-tier Tribunal (Tax Chamber) — if restoration is refused, within 30 days of the decision. The Tribunal can overturn the decision or direct reconsideration.

Important: do not file a Notice of Claim and a Restoration request simultaneously without legal advice — this complicates the case. Typical strategy: restoration first (cheaper, faster); if refused — appeal to the Tribunal; in parallel — Notice of Claim if there are grounds to challenge the lawfulness of the seizure itself.

When you need to instruct a solicitor

The majority of detentions are resolved by a good customs broker. You absolutely need a solicitor (or barrister specialising in customs/trade law) when:

• The value of the goods exceeds £25,000 and seizure is a real risk
• HMRC has opened an investigation (not merely detention) — indicated by a summons to provide explanations under PACE caution
• There is an allegation of smuggling, fraud or money laundering (MLA 2002, Proceeds of Crime Act)
• The case involves sanctions (Russia, Belarus, Iran) — here an error can cost millions and carry personal criminal liability for company directors
• The matter goes to Tribunal — you can represent yourself, but statistics are clear: with a solicitor your chances of success are three times higher
• The case has an IPR element (trademark infringement) — Border Force works closely with brand owners and civil liability exposure is significant

Easy Clearance handles the first line of defence (HMRC liaison, documents, restoration request). Where court proceedings are required, we escalate to trusted solicitors in Manchester and London — the client receives a direct introduction and briefing, and negotiates fees directly.

What not to do — common importer mistakes

• Failing to respond to the Notice — silence is treated as default acceptance of the seizure after 30 days
• Paying "under the table" to speed things up — HMRC does not accept bribes; this is an extortion attempt (fraudsters impersonate HMRC officers)
• Submitting a "corrected" invoice with different figures — this constitutes attempted document fraud and is a criminal offence
• Calling without an MRN — HMRC will not respond without a reference number
• Leaving it until tomorrow — every day costs £200–£800
