Calculate Import Duty: USA to UK

After Brexit, the UK adopted its own UK Global Tariff (UKGT) and stopped operating under the EU Common External Tariff for new imports. The UK and the US have repeatedly attempted a comprehensive bilateral FTA without success. As of June 2026, US-origin goods entering the UK pay the UKGT MFN rate, with limited sectoral arrangements (steel, aluminum, some critical minerals) chipping away at the margins.

This guide walks through the calculation, the regulatory hooks for US exporters, and a worked example. The calculator covers the math.

The duty layers for USA to UK

For a typical US-origin entry into the UK in 2026:

1. UKGT MFN rate for the eight-digit commodity code.
2. UK import VAT of 20 percent (or 5 / 0 percent reduced) on the customs value plus duty plus customs handling.
3. Sectoral arrangements may reduce duty on certain steel, aluminum, and critical minerals.
4. UK trade remedies if applicable (active AD/CVD orders on specific US-origin goods are rare but exist).

No equivalent of Section 122 applies; the UK has not imposed a reciprocal across-the-board surcharge.

UKGT: simpler than the EU CET

UKGT was designed to be lighter and simpler than the EU CET. Key features:

• About 47 percent of UKGT lines are zero MFN, versus about 25 percent for the EU CET.
• Many specific-duty lines were converted to ad valorem for simplicity.
• A "no tariffs on goods we do not produce" principle drove a wave of reductions in 2021.

For US exporters, the practical impact is that capital goods, machinery, electronics, and many chemical inputs enter at zero MFN. The pain points remain in agricultural goods, finished consumer products in textile and footwear, and some auto categories.

The 2025 US-UK steel/aluminum deal

In May 2025 the UK and US reached an Economic Prosperity Deal that restored zero tariffs on a quota of UK steel exports into the US (resolving the long-running Section 232 friction on the UK side) and contained reciprocal commitments. From a US-to-UK perspective the deal:

• Confirmed zero UK duty on US steel within an annual quota of 2 million tonnes (replaced with revised volumes since).
• Set up a working group on aluminum that has yielded reduced UK duty on certain US aluminum derivatives.
• Created a critical minerals chapter facilitating US battery materials exports.

The deal is not a full FTA and does not change the MFN baseline outside the covered sectors. Within scope, however, US exporters benefit.

Worked example: 250,000 USD of industrial machinery

You are exporting a custom-built injection molding machine from Ohio to a UK industrial customer. HTS 8477.10 (injection molding machines for plastics), UKGT MFN 0 percent. Total invoice 250,000 USD CIF Felixstowe (including 8,500 USD ocean freight and 1,200 USD insurance). Exchange rate at the date of importation 0.79 GBP per USD, so the customs value in GBP is 197,500 GBP.

The buyer is VAT-registered and uses postponed VAT accounting, so the 39,570 GBP VAT is a paper entry only. Net cash cost to the buyer: zero duty.

Compare to a similar import from Germany: under the EU-UK Trade and Cooperation Agreement, German-origin machinery also enters at zero MFN, but the UK lost the EU single-market processing simplicity, so customs friction is similar to the US case.

High-traffic HS chapters for USA to UK

• Chapter 84 and 85 (machinery, electronics): typically zero MFN. The duty story is benign; logistics dominate.
• Chapter 87 (vehicles): UKGT 10 percent on passenger vehicles, plus 20 percent VAT. US-built EVs face exactly this stack; no preferential arrangement.
• Chapter 90 (instruments, medical devices): typically zero MFN. UKCA marking required.
• Chapter 22 (alcoholic beverages): UK excise duty plus duty plus VAT. Bourbon and US whiskey saw a temporary tariff in 2018-21 dispute; current MFN around 0 percent under WTO.
• Chapter 24 (tobacco): UK excise duty is heavy.
• Chapter 2, 4 (meat, dairy): highly restricted; specific UKGT rates plus standards inspection.

US export-side considerations

A USA to UK export has US export controls to navigate before UK import is even possible:

• EAR (Export Administration Regulations): most commercial goods. EAR99 is the catchall designation for items without a specific ECCN; these usually need no license for the UK (a Country Group A:1 country). Items with ECCN codes need license determination per the Commerce Country Chart.
• ITAR (defense): State Department licensing required for ITAR-covered goods.
• OFAC sanctions: not typically an issue for UK destinations.
• Electronic Export Information (EEI): required via AES for any shipment over 2,500 USD or any licensable item, regardless of value.

UK importer of record and EORI

The UK importer must be the holder of a UK EORI. For US exporters selling DDP (delivered duty paid), the seller must arrange for a UK importer of record. Three common structures:

1. Buyer-as-importer: simpler. Most US exporters quote DAP or CIF, leaving import to the buyer.
2. UK indirect customs representative: a UK-based firm acts as IOR. The US exporter remains commercially the seller but the UK firm handles clearance and VAT. Joint liability for the UK firm.
3. UK subsidiary: incorporate a UK Ltd, register for EORI and VAT, become your own IOR.

Choice depends on volume and tax structure. Single-shipment occasional exporters use option 1. Regular high-volume exporters consider option 3.

ATA Carnet for samples and trade shows

If you are shipping samples to UK trade shows or sending professional equipment for short-term use, an ATA Carnet (issued in the US by the US Council for International Business) lets you import temporarily without paying duty or VAT, provided the goods leave within a year. Carnets cover:

• Commercial samples (no resale)
• Professional equipment (cameras, scientific instruments)
• Goods for exhibition or display

Carnet limitations: cannot be used for goods to be sold, gifted, or processed in the UK.

Customs clearance and the UK CDS

The UK Customs Declaration Service (CDS) is the digital filing platform since CHIEF was retired. The data elements include:

• Commodity code (UKGT 8-digit, plus 2 more digits for declaration)
• Country of origin (US)
• Customs procedure code (typically 4000 for permanent import)
• Customs value
• Documentation references (commercial invoice, packing list, BoL)

Brokerage typically costs 50 to 150 GBP per entry. DHL, FedEx, UPS bundle brokerage at higher costs but with door-to-door visibility.

How the calculator handles this lane

When you select Origin: USA and Destination: United Kingdom in the calculator:

1. Looks up UKGT MFN rate.
2. Applies UK import VAT at the appropriate rate.
3. Notes sectoral arrangements where the US-UK 2025 deal applies (specific steel and aluminum lines).
4. Flags ATA carnet eligibility for samples and short-term use cases.
