US Brand Selling in UK: Requirements 2026

Updated October 2026

A US brand selling in the UK in 2026 needs a UK business entity, UK VAT registration (20%, no threshold for overseas sellers), a UK EORI number, a licensed Importer of Record, and product compliance clearance before listing a single product. The UK ecommerce market is worth an estimated $317 billion in 2026, growing at 9.7% annually (Mordor Intelligence, 2026). Most US brands take 8 to 12 weeks to complete the compliance stack themselves. With a Merchant of Record, the same setup takes 7 to 10 business days.

TL;DR

• US brands must register a UK Ltd company to sell on UK platforms including TikTok Shop, Amazon UK, and Shopify UK stores

• HMRC classifies all US sellers as Non-Established Taxable Persons (NETPs) with a £0 VAT threshold, not the domestic £90,000

• You need a GB EORI number, a licensed IoR, and product compliance review before your first shipment clears customs

• DIY setup costs £3,000 to £8,000 and takes 8 to 12 weeks; an MoR route costs 2.5% to 5% of GMV and takes 7 to 10 business days

• Postponed VAT Accounting means you do not pay 20% import VAT in cash at the border

Do US brands need a UK entity to sell in the UK?

Yes. Every major UK sales channel requires a UK-registered business entity. TikTok Shop UK requires a UK Ltd company, a UK business address matching Companies House, and a UK bank account. Amazon UK accepts overseas entities for Seller Central but requires UK VAT registration regardless. Shopify merchants selling to UK consumers from US warehouses still trigger HMRC obligations on their first sale.

Your Delaware LLC, C-Corp, or S-Corp does not exist in HMRC's system. Companies House registration is the first step in a sequential compliance chain, and every subsequent requirement depends on it.

Setting up a UK Ltd company through Companies House takes 24 to 48 hours online (GOV.UK, 2026). But the entity is just wall number one.

What is the UK VAT requirement for US ecommerce sellers?

UK VAT registration is mandatory for US brands from their first UK sale. There is no exemption, no threshold, and no grace period.

HMRC classifies every business without a UK establishment as a Non-Established Taxable Person (NETP). The domestic £90,000 VAT threshold does not apply to NETPs (HMRC VAT Notice 700/1, 2026). Your registration obligation begins with your first taxable supply in the UK.

The standard UK VAT rate is 20%. Reduced rates of 5% and 0% apply to specific categories (children's clothing, books, certain food items).

Three things US brands need to know about UK VAT in 2026:

1. HMRC can backdate your registration. If you sell without registering, HMRC can retrospectively register you from the date of your first UK supply. That means back-VAT, penalties of up to 15% of the VAT owed, and interest on every sale.

2. Making Tax Digital (MTD) is mandatory. All VAT-registered businesses must file quarterly returns through MTD-compatible software. Paper returns are not accepted (GOV.UK MTD, 2026).

3. US sales tax registration has no standing with HMRC. Your state-level sales tax setup is irrelevant in the UK. Separate system, separate jurisdiction, separate returns.

HMRC VAT registration for overseas applicants takes 4 to 8 weeks. Some applications take longer if HMRC requests additional documentation, which is common for non-UK applicants.

What is a UK EORI number and do US brands need one?

Yes. A GB EORI (Economic Operators Registration and Identification) number is required for every customs declaration when importing goods into the UK. Without it, your inventory sits at the border.

HMRC issues GB EORI numbers to businesses with an active UK VAT registration. The application is free and takes 5 to 10 working days (GOV.UK EORI guidance, 2026). The EORI number is linked to your VAT number, which is why VAT registration must come first.

US brands cannot use their US Customs and Border Protection numbers for UK imports. The UK and US operate entirely separate customs systems post-Brexit.

If you are also selling into the EU, you need a separate EU EORI number. The two are not interchangeable.

What is an Importer of Record and why does it matter?

The Importer of Record (IoR) is the legal entity HMRC holds responsible for every customs declaration. This covers import duties, import VAT, product compliance, and record-keeping for six years.

For US brands shipping inventory to the UK, someone must act as IoR on every shipment. Your US entity cannot hold this role. Your freight forwarder may file the customs paperwork, but filing paperwork and carrying legal liability are two different things.

The IoR question has direct financial consequences. HMRC's policy is clear: only the owner of the goods at the point of import can reclaim import VAT. If your freight forwarder's EORI appears on the declaration instead of yours (or your MoR's), you cannot reclaim 20% import VAT. On £100,000 of stock, that is £20,000 in unrecoverable cost.

What product compliance do US brands need for the UK market?

UK product compliance requirements apply to all goods sold to UK consumers, regardless of the seller's country of origin. The key requirements for US brands in 2026:

UKCA and CE marking. The UK Government confirmed in August 2024 that CE marking will continue to be accepted indefinitely for goods placed on the Great Britain market. US brands with CE-marked products do not need separate UKCA certification. Products without CE marking need to obtain either UKCA or CE marking before sale.

UK Responsible Person. For regulated product categories (electronics, toys, cosmetics, PPE, radio equipment), UK law requires a UK-based Responsible Person. This person holds technical documentation, responds to the Office for Product Safety and Standards (OPSS), and takes corrective action if required. The Responsible Person must have a UK address. Your US office does not qualify.

Labelling. All products sold in the UK must carry English-language labelling with a UK address. Weight and volume must be in metric units. Country of origin must be stated. For cosmetics, the SCPN (Cosmetic Product Notification Portal) replaces the EU's CPNP.

Packaging waste. The UK's Extended Producer Responsibility scheme requires brands selling more than 25 tonnes of packaging annually to register with the relevant environment agency and report packaging data.

How much does UK market entry cost for a US brand?

The costs divide into two paths: DIY entity setup or Merchant of Record.

US brand UK entry: cost and timeline comparison (October 2026)

The breakeven point is approximately £200,000 to £400,000 in annual UK revenue. Below that, an MoR is almost always cheaper. Above £2M, an own entity starts to win on unit economics.

The smart play for most US brands: start with an MoR, validate the market with real sales data, then graduate to your own entity once revenue justifies the fixed costs.

What is the UK market opportunity for US brands in 2026?

The UK is the third-largest ecommerce market globally. Key figures for 2026:

• Market size: $317 billion in ecommerce revenue, growing at 9.7% annually (Mordor Intelligence, 2026)

• Online penetration: over 82% of UK adults shop online regularly

• Language: shared English language reduces localisation costs to near zero

• Social commerce: TikTok Shop UK is the fastest-growing online retailer in the UK (NielsenIQ, 2025). Over 200,000 SMBs sell on TikTok Shop UK, with 6,000+ daily LIVE sessions

• Consumer appetite: UK consumers actively seek American brands, particularly in beauty, wellness, fashion, and home categories

The opportunity is not theoretical. But compliance is the gatekeeper.

What is the fastest way for a US brand to start selling in the UK?

Two paths. Both lead to the same destination. The difference is speed and capital risk.

Path 1: DIY entity setup. Register a UK Ltd, apply for VAT, wait for HMRC, apply for EORI, wait again, open a UK bank account, wait again, find an IoR, complete product compliance review. Total: 8 to 12 weeks, £3,750 to £11,800 in setup costs.

Path 2: Merchant of Record. A licensed MoR already has the UK entity, VAT registration, EORI, IoR status, and compliance infrastructure in place. You go live under their entity in 7 to 10 business days.

The MoR route does not mean less compliance. It means the compliance is already done. You trade a percentage of GMV for immediate market access and zero upfront entity costs.

How does Postponed VAT Accounting work for US brands?

Postponed VAT Accounting (PVA) is the UK's system for handling import VAT without cash at the border. Instead of paying 20% import VAT to HMRC when your goods clear customs, you account for it on your quarterly VAT return.

This is a significant cash flow advantage. On £100,000 of imported stock, PVA saves you £20,000 in upfront cash. You still owe the VAT, but you offset it as input tax on the same return, making the net cash impact zero for most sellers.

PVA is available to all UK VAT-registered importers. Your customs broker or IoR selects PVA on the import declaration. The VAT then appears on your monthly postponed import VAT statement, which you include in your next quarterly return.

Without PVA, you would need to pay 20% of the goods value plus any duty at the point of import and then wait for the next quarterly return to reclaim it. For high-volume sellers, that cash gap can be six figures.

FAQ

Can a US LLC sell directly on TikTok Shop UK? No. TikTok Shop UK requires a UK Ltd company registered at Companies House, a UK bank account, and a UK VAT number. US LLCs and C-Corps are not accepted.

Is the £90,000 VAT threshold available to US brands? No. The £90,000 threshold applies only to UK-established businesses. HMRC classifies US sellers as NETPs with a £0 threshold. Registration is required from the first sale.

How long does HMRC VAT registration take for a US company? 4 to 8 weeks for overseas applicants. HMRC commonly requests additional documentation from non-UK companies, which can extend the timeline.

Do US brands need a UK bank account? For TikTok Shop UK, yes. TikTok pays out to UK bank accounts only. For other channels, requirements vary. Opening a UK business account as a non-resident director takes 2 to 6 weeks.

Can US brands use their existing CE marking in the UK? Yes. The UK Government confirmed CE marking is accepted indefinitely on the Great Britain market as of August 2024.

What is the £135 consignment rule? For consignments valued at £135 or less, the UK marketplace or overseas seller must collect and remit VAT at the point of sale. For consignments above £135, import VAT is collected at the border (or via PVA). This threshold determines who collects VAT, not whether VAT applies.

How much does a Merchant of Record charge? Typically 2.5% to 5% of GMV. This covers entity use, VAT registration, EORI, IoR, customs clearance, compliance, and accounting. No upfront setup fees with CRSSBRDR.

What happens if a US brand sells in the UK without VAT registration? HMRC can retrospectively register the business, charge back-VAT on all UK sales, apply a late registration penalty of up to 15%, and charge interest from the date VAT should have been collected.
