If you are buying or receiving something from Japan and having it shipped to the United Kingdom, the total you pay is rarely just the item price and postage. UK import rules add VAT, sometimes customs duty, and often a courier handling fee. This page is a general estimate and guide to help you anticipate those costs. It is not tax advice, and the figures below can change, so treat them as a starting point rather than a final bill.
The GBP 135 threshold
The single most important number for UK imports is GBP 135. This is the value of the consignment (the goods themselves, excluding shipping and insurance) that decides how VAT is collected.
For consignments valued at or below GBP 135, UK VAT is generally charged at the point of sale. The seller or the online marketplace is expected to register for UK VAT and collect the standard 20 percent at checkout. In that situation, nothing further should be due when the parcel lands, and no customs duty applies at this level.
For consignments valued above GBP 135, VAT is not collected at the point of sale. Instead, import VAT and any customs duty are charged when the goods enter the UK, usually handled by the courier or postal operator on your behalf. You typically pay before the parcel is released for delivery.
How the value is assessed
Customs looks at the value declared on the shipment. For the GBP 135 test, this is normally the price of the goods alone. Once you are over the threshold and duty and import VAT come into play, the calculation broadens: import VAT is usually charged on the goods plus shipping and insurance plus any duty. Because shipping from Japan can be significant, this can push the final amount higher than the item price alone suggests. Values in yen are converted to sterling using the exchange rate customs applies, which may differ from the rate you saw at checkout.
Duty depends on the commodity code
Customs duty is not a single flat rate. It depends on the commodity code (also called a tariff or HS code) that describes what the item actually is. Some categories carry a zero rate, while others attract several percent or more. Duty may also be waived when the calculated amount is very small. Because rates vary so widely by product, the only reliable way to estimate duty is to look up the specific commodity code for your item.
Gifts versus goods
Parcels marked as genuine gifts sent from one private person to another can be treated differently from commercial purchases, and a limited gift relief may apply below a set value. This relief does not cover items you have bought for yourself, and mislabelling a purchase as a gift is not permitted. The sender's customs declaration is what matters here, so how the parcel is described in Japan affects what you are charged in the UK.
Courier disbursement and handling fees
When a courier pays import VAT or duty to customs for you, it usually adds its own handling or disbursement fee for doing so. This is a separate charge from the tax itself and is set by the carrier, not the government. It can feel disproportionate on lower value shipments, so it is worth factoring in when comparing shipping methods. Our guide to EMS vs DHL vs surface looks at how carriers differ on speed, cost, and these clearance charges.
