Import Tax From USA to UK 2026: A GBP 135 Decision Tree

The first fork: GBP 135, and almost nothing above it behaves the same way

Every consignment from the United States to Great Britain splits at one number: GBP 135. Below it, non-excise goods that you bought yourself carry no customs duty at all, and the seller is supposed to have collected the 20% VAT at checkout. Above it, duty appears, import VAT moves from the seller to the courier, and the parcel does not move until somebody pays a bill that includes freight and packaging in the taxable base. That is not a small administrative difference. On a GBP 400 order of US-made parts the tax exposure is roughly 22%, and on a GBP 400 order of US-made knitwear it is roughly 34% once the 12% textile duty is stacked underneath the VAT. Same dollar invoice, same courier, two different outcomes, and the fork is value plus commodity code, nothing else.

I price US-to-UK consignments for small importers most weeks, and the mistake I see is almost always the same one: treating that GBP 135 line as a business exemption. It is not. HMRC applies it to the consignment, whoever is buying, which means a company buying GBP 90 of samples gets the same duty relief as a private shopper buying GBP 90 of trainers. What changes above the line is not just the duty, it is who is legally on the hook for the VAT and when the money leaves your account. A client in Bristol bought GBP 11,400 of packaging machinery from a supplier in New Jersey in March 2026 and was surprised to find the courier asking him for GBP 2,703 before release. Nothing had gone wrong. He had simply never priced the second half of the bill.

Below GBP 135: the cleanest import there is, until the seller is not registered

The sub-GBP 135 route only stays clean when the seller has done the work. Since 1 January 2021, an overseas seller or an online marketplace that sells you goods valued at GBP 135 or less has been expected to register for UK VAT, charge the 20% at the point of sale and remit it to HMRC. When that happens, the parcel arrives with nothing owing and the buyer's total cost is the checkout total. When the seller is a small US workshop that never registered, the VAT does not disappear. It comes back at the border, and the courier adds a collection charge on top.

This is where I see the most expensive surprises on this lane, because the goods are cheap enough that nobody models the downside. A GBP 118 order of US-supplied guitar pedals from a seller who is not UK registered lands as GBP 118 plus 20% VAT of GBP 23.60 plus a collection fee that has typically run between GBP 8 and GBP 15 on postal items in my experience. Call it GBP 150, or about 27% above the ticket price. If the same seller had registered, the buyer would have paid GBP 141.60 at checkout and nothing on the doorstep. The 20% is not avoidable. Whether it arrives as a line on an invoice or as a demand from a courier is entirely a function of whether the seller set up a UK VAT registration, and that is a question worth asking before you place the order, not after.

• Ask the seller in writing whether UK VAT is included in the checkout price. If the answer is yes, the transaction ends at checkout.
• If the answer is no, budget 20% of the goods value plus a collection fee and expect the courier to hold the parcel.
• Couriers normally hold an unpaid parcel for around three weeks before returning it to the sender, which is how good reviews on a cheap order turn into a refund you have to chase.

Above GBP 135: duty stacks, and then VAT stacks on the duty

Once the consignment crosses GBP 135, two taxes arrive in sequence and the second one is charged on the first. Customs duty is calculated on the price you paid plus postage, packing and insurance. Import VAT is then charged at 20% on that same customs value plus the duty. That ordering is why a 12% duty line never costs 12% of the goods. On GBP 20,000 of US cotton T-shirts under commodity code 6109.10, the duty is 12% of the landed value and the VAT is 20% of the sum. Freight drags the whole calculation upward because it sits inside both bases, so the cheapest possible freight quote and the lowest possible duty rate are the only two levers that actually move a US-to-UK bill.

I run the numbers in that order every time, and I write the duty and the VAT next to every freight quote before I look at transit time. A GBP 2,400 saving on freight sounds like a win until you work out that on a 12% line it only removes about GBP 538 of total tax, because the freight you cut was also carrying VAT. The reverse is the part people miss: paying for faster freight to protect a delivery date increases the taxable value and therefore the tax bill, so the true cost of speed is the air or premium rate plus 20% VAT on that rate. Nobody puts the second half in the spreadsheet. I have watched a GBP 900 air surcharge turn into GBP 1,080 of cash out the door for exactly one reason, and it was arithmetic, not negotiation.

• Step 1: customs value equals goods plus freight plus packing plus insurance to the UK.
• Step 2: duty equals the commodity rate multiplied by the customs value.
• Step 3: import VAT equals 20% multiplied by the customs value plus the duty.
• Step 4: if you are UK VAT registered, postponed VAT accounting lets you declare and recover that VAT on the same return instead of paying it at the border.

The excise branch: alcohol, tobacco and vehicles ignore the GBP 135 line

The GBP 135 relief only covers non-excise goods. Alcohol, tobacco and anything else under excise duty pay customs duty and VAT at any value, with no threshold and no small-consignment kindness, and spirits over 35 centilitres without a UK duty stamp can be seized. Vehicles are their own branch because the duty rate is high and the UK tax stack on a car is not just duty plus VAT. For a US-built passenger car under code 8703.21, the third-country duty is 10% of the landed value, new or used, and on top of that the vehicle has to be registered and may need type approval or an individual vehicle approval before it can be driven.

I stopped quoting cars on a single number years ago. A US pickup arriving in Southampton has a duty line, a VAT line, a registration process and a physical inspection before it is road legal, and the clock on demurrage runs through all of it. The duty rate itself is not the trap. The trap is that a 10% rate on a GBP 45,000 vehicle is GBP 4,500, the VAT on the resulting GBP 49,500 is GBP 9,900, and the vehicle has not yet been approved or plated. If the model is not on a recognised approval route, you own a very expensive static object until the paperwork catches up. I would not buy a US vehicle to import on price alone.

Then the commodity code decides the rest: what US goods actually pay in 2026

There is no United States-United Kingdom free trade agreement, so US-origin goods enter the UK under the same third-country rates as everything else and there is no preference to claim and no certificate of origin that reduces the bill. What saves money is the code. I pulled the live UK rates from the Trade Tariff service while writing this, and the spread across ordinary goods is the whole story of why US sourcing is cheaper in some categories than in others. Machinery, electronics, pharmaceuticals-adjacent goods and a lot of furniture enter at zero. Apparel enters at 12%. Get the code wrong and you overpay by a margin that dwarfs anything a forwarder can negotiate away.

The 2025 deal helps UK exporters, not UK importers

Here is the part that USA-to-UK guides usually get backwards. The UK and the United States announced the Economic Prosperity Deal on 8 May 2025 and it came into effect on 30 June 2025, and it is a genuinely important agreement. It is also pointed the other way. The deal cut United States tariffs on UK goods, not UK tariffs on United States goods: US tariffs on UK cars fell from 27.5% to 10% on the first 100,000 UK car exports per quarter, and steel and aluminium exports moved toward zero subject to supply chain conditions. Nothing in it removes a penny of UK duty on a consignment arriving from New Jersey. If you import from the United States into Britain, that deal is somebody else's win.

I have had three conversations in the past year where a buyer told me the UK had a trade deal with the US now, so the duty was gone. Each time I showed them the same thing: the UK Global Tariff, applied on origin, with no preference for US goods. What makes this more than a technicality is the direction of the flows. The Office for National Statistics, in an article published on 30 April 2026 covering data to February 2026, found that UK goods exports to the United States fell by GBP 1.5 billion, or 24.7%, to GBP 4.7 billion in April 2025 after the US tariffs landed, that the United States remains the UK's largest goods export partner and third-largest goods import partner, and that by late February 2026, 33.0% of British exporters with ten or more employees said they had been affected by US tariffs in the previous month. The trade in goods balance with the United States turned to a deficit for three consecutive months from December 2025. Every headline number in that paragraph is about UK exporters paying more, and none of them changes what a UK importer pays on US-origin goods.

• No UK-US free trade agreement exists. Talks opened on 5 May 2020 and have never concluded.
• The 2023 Atlantic Declaration was a commitment to cooperate, not a tariff-cutting agreement.
• The 2025 Economic Prosperity Deal reduced US tariffs on UK exports, and left UK tariffs on US imports on the UK Global Tariff.
• Imports from the United States reached GBP 5.3 billion in January 2026, mostly fuels and machinery, so the duty-only reading is not theoretical for anyone buying capital equipment.

The American half of the paperwork: EEI, the ITN and the USD 2,500 line

The United States does not levy an export duty, which is a real advantage compared with the IOSS-era EU, but it does police the paperwork. Under 15 CFR 30.37, an exporter does not have to file Electronic Export Information when the value of the commodities shipped from one US principal party in interest to one ultimate consignee, on a single conveyance, under an individual Schedule B number, is USD 2,500 or less. Above USD 2,500 on a single Schedule B line, the filing goes through the Automated Export System and the shipment comes back with an Internal Transaction Number, the ITN, which has to travel with the cargo. Certain destinations and licences trigger the filing at any value, but for ordinary US-to-UK commercial goods the USD 2,500 line is the one that decides whether your forwarder needs a filing from you.

I now put the ITN requirement in the purchase order notes for anything above the line, because the failure mode is a container sitting at a US terminal while somebody discovers that the filing was never made. The good news on this lane is that there is no US equivalent of a customs duty at export, so the American end is paperwork and time rather than money. The line also cuts the other way for a small buyer: a single shipment of, say, USD 2,300 of tools does not need the filing, while the same tools split across three Schedule B codes totalling USD 4,000 may need one or more, because the test is per Schedule B number, not per shipment total. That nuance catches out people who order mixed pallets.

What the freight really costs in October 2026

Freight on this lane is quoted in two completely different ways and they are not comparable. Port-to-port quotes cover the ocean leg and nothing else. Door-to-door quotes bundle origin haulage, the ocean leg, destination handling, customs clearance and final delivery, and they are often two to three times the port-to-port number for the same box. I pulled live rates on four US-to-UK corridors on 6 October 2026 so you can see the spread as it actually stood. On the same day, a 20ft container from New York to Southampton was being quoted from GBP 1,134, while Los Angeles to London Gateway started at GBP 2,676 for the same box. The gap is not a mistake. It is the Panama Canal and a rail move, and it is why the West Coast is only worth it when the goods are already there.

I reconcile these two ways of quoting like this: a forwarder's indicative 2026 range, around USD 1,800 to USD 3,200 per 20ft from the East Coast, is a bookable contract-style number excluding origin and destination charges, while the live snapshot above is what clears on the day including whatever the carrier is putting on the table, and the gap between the cheapest and the highest sailing on the same corridor is often larger than the gap between two corridors. On 6 October 2026 the spread between the cheapest and the highest New York to Felixstowe sailing was GBP 2,151 on the same port pair in the same week. If you send one rate to your supplier as a budget, you have not priced the lane, you have priced one sailing on it.

• Ocean FCL: 13 to 18 days from the East Coast, 22 to 30 days from the West Coast, billed per container.
• Ocean LCL: 18 to 30 days plus consolidation, billed per cubic metre at roughly USD 90 to USD 180 with a minimum charge, and it stops making sense once you pass 13 to 15 cubic metres.
• Air freight: 3 to 6 days airport to airport, billed per kilogram of chargeable weight.
• Express: 1 to 3 days, billed per kilogram, best for samples and documents.
• The three UK gateways that take almost all deep-sea US volume are Felixstowe, Southampton and London Gateway, and Felixstowe is the largest UK container port.

Three consignments, three bills, and the four stop-loss lines

Take three real shapes of US-to-UK shipment and put the arithmetic next to each one. Consignment one is industrial: GBP 11,400 of packaging machinery and spare parts, code 8481 at 2%, GBP 620 of freight, GBP 45 of insurance. Customs value is GBP 12,065, duty is 2% at GBP 241.30, and import VAT is 20% of GBP 12,306.30, which is GBP 2,461.26. Consignment two is consumer: GBP 20,000 of cotton T-shirts at 12% with GBP 900 of freight and GBP 60 of insurance. Customs value is GBP 20,960, duty is GBP 2,515.20, and VAT is 20% of GBP 23,475.20, which is GBP 4,695.04. Consignment three is the awkward one: GBP 400 of T-shirts with GBP 55 of courier freight, where duty is GBP 54.60 and VAT is GBP 101.92 on a parcel nobody thought twice about.

Read the last row and the whole lane becomes obvious. The machinery is the cheapest thing to import from the United States because its duty rate is 2%, and the T-shirts cost nearly 40% on top of goods value no matter how well the freight is negotiated. In all three cases the freight is inside the VAT base and the duty is inside the VAT base, so the tax is charged on the tax. Those three worked examples are also where I set my stop-loss lines. If the duty rate is above 10%, recheck the commodity code before you do anything else, because the code is worth more than the freight negotiation. If import VAT is the only significant cost, get a GB EORI number and use postponed VAT accounting rather than funding the VAT at the border. If the freight quote is more than 8% of goods value on a full container, you are pricing the wrong corridor or the wrong sailing. And if the seller will not confirm UK VAT registration on a sub-GBP 135 order, assume the parcel arrives with 20% plus a fee and tell your customer that before they order.

• Get a GB-prefixed EORI number before the first shipment. Without it no declaration can be made in your name.
• Declarations now run through CDS, not the retired CHIEF system, and your agent needs to be set up on it.
• If you are VAT registered, use postponed VAT accounting and keep the C79 as the evidence HMRC accepts for a reclaim.
• If you store goods in the UK for sellers outside the UK, check whether the Fulfilment House Due Diligence Scheme applies to you.
