UK customs: the bill, the hold and the seizure deadlines

GOV.UK's guidance on tax and customs for goods sent from abroad says anything posted or couriered to you from another country goes through customs, and that the parcel or courier company, for example Royal Mail or Parcelforce, is responsible for taking goods through UK customs. It also says you must check that goods sent from outside the UK are declared correctly, and that goods may be seized if the rules are not followed.

On the Oopbuy side, the declaration is made when you submit the parcel. Oopbuy's own customs FAQ warns that customs risks such as returns, fines and taxes are borne by the buyer. Declare what the goods are actually worth.

For non-excise goods bought for delivery to Great Britain, GOV.UK guidance checked 18 October 2026 distinguishes goods worth £135 or less from those above it. The lower-value guidance says VAT is included in the purchase price; above £135 VAT is normally collected by the delivery company and duty depends on the goods and origin. Confirm how the seller/agent and route account for this in your transaction. Northern Ireland has different import rules; use the relevant section of the official page.

When VAT is paid to the delivery company, GOV.UK says it is charged on the total package value, including postage, packaging and insurance. A protection plan bought on a parcel over £135 can therefore form part of the value the VAT is worked out on.

If anything is due, GOV.UK says you will be contacted by Royal Mail, Parcelforce or the courier company with a bill stating exactly which fees you need to pay. They will normally hold the parcel for about three weeks. If you have not paid by then, the parcel is returned to the sender.

That return is where the UK clock meets Oopbuy's exclusions. A parcel returned because the recipient did not pay tax or cooperate with customs is outside delay cover and seizure cover, and a parcel sent back from abroad leaves you paying the redelivery fee. Pay or dispute the bill inside the hold, and tell Oopbuy if the bill looks wrong.

The estimator prints a tax label beside each line. On the United Kingdom table for a 1 kg parcel on 10 October 2026, fourteen lines were labelled Tax free and two, HF-EUB-GB-1 and HP-EMS-GB-1, were labelled Duties Payable by Recipient. All sixteen offered the three protection plans.

The estimator does not define Tax free. Our reading is that the label describes how the line handles import charges, not a promise that no bill can ever arrive. On the two Duties Payable lines, expect a bill if one is due, and plan for the three-week hold. If a bill arrives on a Tax free line, contact Oopbuy the same day and keep the carrier's deadline in view while you wait.

Customs Seizure Protection pays 15% of the actual shipping cost if the parcel is seized or confiscated by customs after dispatch, once Oopbuy has confirmed it. If a clearance attempt fails for other reasons, and the note's example is destruction or confiscation at customs after 90 days, it pays the full product value and shipping, provided valid customs clearance documents are submitted.

It pays nothing if the parcel is held because the recipient did not cooperate, for example by not paying tax, not supplying information or not responding. The same ¥5,000 cap per claim applies. Oopbuy's older article calls this customs fastener insurance; it is the same idea under a different name.

A challenge to the lawfulness of a seizure and a request to get goods back are different processes. GOV.UK says the notice of claim must be received within a month; follow the notice and seek qualified advice promptly where needed. The restoration guidance says there is no formal request deadline, but non-perishable goods are usually destroyed or sold after 45 days and perishable goods may be disposed of immediately. Do not treat 45 days as a safe waiting period. These pages were checked on 18 October 2026.

These are UK legal deadlines, separate from anything Oopbuy offers. If the seizure concerns goods that are prohibited or infringing, Oopbuy's exclusions apply as well, and no plan pays. For anything else, keep the seizure notice: it is the clearance document a seizure claim will ask for.
