UK Product Compliance Checklist for Ecommerce 2026

Updated October 2026

Every US or EU brand selling physical products into the UK must clear six compliance gates before a single unit ships. Miss one and your stock gets held at the border, your marketplace listings get pulled, or HMRC freezes your payouts. This checklist covers every requirement in one place, with current rules, real costs and timelines as of October 2026.

TL;DR

  • CE marking is still accepted in Great Britain indefinitely. You do not need UKCA marking for most product categories.

  • You need a UK-based Responsible Person for regulated products (electronics, toys, cosmetics, PPE).

  • UK VAT registration is mandatory if you hold stock in the UK. Standard rate: 20%.

  • A UK EORI number is required for every customs declaration.

  • An Importer of Record (IoR) based in the UK must be named on every shipment.

  • Product labelling must include a UK address, English-language safety information and the correct conformity marking.

What does UK product compliance actually cover?

UK product compliance is the full set of legal, customs and regulatory requirements a brand must satisfy to sell physical goods in England, Scotland and Wales. It spans six areas: product safety and conformity marking, labelling, a UK Responsible Person, VAT registration, customs (EORI and IoR) and category-specific rules for products like cosmetics, electronics and food supplements.

Since Brexit, the UK operates its own regulatory regime. EU compliance does not automatically transfer. Even if your products carry CE marking and meet every EU directive, you still need UK-specific registrations, a UK-based contact and UK customs documentation.

The Product Regulation and Metrology Act 2025, which received Royal Assent in July 2025, is now the foundation for UK product safety. Three linked consultations published by the UK government on 31 March 2026 propose the most significant reform of the product safety regime in over two decades. New secondary legislation is expected to introduce stricter accountability across supply chains.

Do I need UKCA marking or is CE marking enough?

For most product categories, CE marking is enough. In August 2023, the UK government confirmed that CE marking would be recognised indefinitely in Great Britain for products covered by the same sectoral regulations that previously required CE marking. This includes electrical equipment, machinery, PPE, toys, EMC-regulated products and more.

You can use either CE or UKCA marking. Both are valid. If your products already carry CE marking for the EU market, there is no need to switch to UKCA for Great Britain.

However, there are exceptions. Some product categories have specific UK rules that diverge from EU requirements. Always check the relevant statutory instrument for your product type via the GOV.UK product marking table.

For Northern Ireland, the rules differ again. The Windsor Framework means Northern Ireland follows EU conformity rules with a UK(NI) marking. If you sell across the entire UK (Great Britain plus Northern Ireland), CE marking is the simplest option because it covers both markets.

Bottom line: CE-marked products from the US or EU can enter Great Britain without UKCA conversion. This saves thousands in re-certification costs and months of delay.

What is a UK Responsible Person and do I need one?

Yes, if your products fall under sector-specific regulations. A UK Responsible Person must be established in the UK and named on the product or its packaging. This applies to electronics, toys, PPE, cosmetics, medical devices and several other regulated categories.

The Responsible Person is accountable for:

  • Holding the technical documentation and Declaration of Conformity

  • Providing information to market surveillance authorities (OPSS, Trading Standards) on request

  • Taking corrective action if the product is found non-compliant

For non-UK manufacturers, the importer or an authorised representative based in the UK can serve as the Responsible Person. Without one, your products may be blocked at the border or removed from online marketplaces.

The OPSS Delivery Report 2025-2026 confirms the Office for Product Safety and Standards is increasing enforcement activity, particularly for products sold by overseas sellers through online marketplaces. TikTok Shop, Amazon UK and other platforms are tightening compliance checks in response.

For CRSSBRDR clients: CRSSBRDR acts as your UK Responsible Person and IoR, so this requirement is handled from day one.

What UK labelling requirements apply to imported products?

Every product sold in the UK must carry:

  1. UK address. The name and postal address of the manufacturer, importer or UK Responsible Person must appear on the product or packaging. A PO box alone is not sufficient.

  2. English-language information. All safety warnings, instructions for use and product information must be in English.

  3. Conformity marking. CE or UKCA marking where applicable, with the correct dimensions (minimum 5mm height) and proportions.

  4. Traceability information. A product type, batch or serial number so the product can be identified and traced.

  5. Category-specific labels. Cosmetics require INCI ingredient lists and a UK SCPN (Submit Cosmetic Product Notification) reference. Food products need UK-format nutrition labels. Textiles need fibre composition labels.

Relabelling at a UK warehouse before distribution is common for US brands entering the market. EU brands typically need fewer changes but must add a UK address and check that any EU-specific references (such as EU Responsible Person details) are supplemented with UK equivalents.

Do I need UK VAT registration to sell online in the UK?

Yes. If you hold stock in the UK (including Fulfilled by TikTok warehouses or Amazon FBA), you must register for UK VAT regardless of your sales volume. The standard UK VAT rate is 20%.

The £90,000 VAT registration threshold applies only to UK-established businesses. Non-UK businesses storing inventory in the UK have no threshold: registration is mandatory from the first unit.

VAT registration typically takes 4 to 6 weeks through HMRC, though delays of 8 to 12 weeks are common for non-UK applicants without a UK fiscal address. CRSSBRDR clients receive VAT registration as part of the onboarding process, with go-live in 7 to 10 business days.

For a full breakdown, see our guide: UK VAT for EU brands selling online in 2026.

What is a UK EORI number and why do I need one?

An EORI (Economic Operators Registration and Identification) number is required for every customs declaration when importing goods into the UK. Without one, your shipments cannot clear UK customs.

UK EORI numbers start with "GB" followed by 12 digits. If you already have an EU EORI number, you still need a separate UK EORI post-Brexit.

Apply through HMRC's online service. Processing takes up to 5 working days for UK-established businesses, but non-UK applicants may wait 2 to 4 weeks.

What is an Importer of Record and do I need one?

Yes. UK law requires that every commercial shipment entering the UK has a named Importer of Record (IoR) who is responsible for customs duties, import VAT and product compliance at the point of entry.

The IoR must be established in the UK. If you are a US or EU brand without a UK entity, you cannot act as your own IoR. You need either a UK subsidiary, a customs broker arrangement, or a Merchant of Record that includes IoR services.

CRSSBRDR operates as a licensed IoR in the UK, handling customs clearance, duty payments and compliance documentation for every shipment. This is included in the MoR service, not charged separately.

What category-specific compliance rules apply?

Cosmetics and skincare

  • UK Responsible Person. Mandatory. Must hold the Product Information File (PIF).

  • Safety assessment. A qualified safety assessor must sign off the Cosmetic Product Safety Report (CPSR).

  • Labelling. INCI ingredient list, batch code, PAO (Period After Opening) symbol, and UK Responsible Person address.

Electronics and electrical products

  • CE or UKCA marking required under the Electromagnetic Compatibility Regulations 2016 and the Electrical Equipment (Safety) Regulations 2016.

  • UK Declaration of Conformity referencing UK regulations (not just EU directives).

  • Test reports from an accredited laboratory.

What are the penalties for non-compliance?

The consequences are immediate and expensive:

  • Border seizure. UK Border Force and Trading Standards can seize non-compliant goods at the port of entry. You pay storage fees while the issue is resolved.

  • Marketplace removal. TikTok Shop, Amazon UK and other platforms remove non-compliant listings and may suspend seller accounts. Amazon UK gives 5 working days to provide compliance documentation before pulling a listing.

  • Criminal prosecution. Under the Consumer Protection Act 1987, fines reach up to £20,000 per offence in magistrates' court and unlimited fines in Crown Court. Serious offences carry up to 12 months imprisonment.

  • Payout freezes. TikTok Shop and marketplace payment providers can freeze seller payouts pending compliance verification.

  • Product recalls. The OPSS can mandate public product recalls at the seller's expense.

Frequently asked questions

Can I sell in the UK without a UK entity? Yes. A Merchant of Record like CRSSBRDR provides the UK entity, VAT registration, EORI and IoR you need. You do not need to incorporate a UK company.

Is CE marking still valid in the UK in 2026? Yes. The UK government confirmed in August 2023 that CE marking is recognised indefinitely in Great Britain for most product categories. No switch to UKCA is required.

Do I need a UK Responsible Person for all products? No. Only products falling under specific sector regulations (electronics, toys, cosmetics, PPE, medical devices) require a UK Responsible Person. General consumer goods without a specific regulatory framework do not.

How long does UK VAT registration take? Directly through HMRC, 4 to 12 weeks for non-UK applicants. Through CRSSBRDR, VAT registration is part of the 7 to 10 business day onboarding.

What happens if I sell without UK VAT registration? HMRC can assess unpaid VAT retrospectively, charge penalties of up to 100% of the tax owed, and issue a public notice. Marketplace payouts will also be frozen.

Do EU brands need to re-certify products for the UK after Brexit? No, for most categories. CE marking is accepted in Great Britain. You may need to add UK-specific labelling (UK address, English-language information) and appoint a UK Responsible Person, but product re-certification is not required.

What is the difference between an Importer of Record and a Merchant of Record? An IoR handles customs clearance and is liable for duties and import VAT at the border. A Merchant of Record (MoR) is a broader service: the MoR becomes the legal seller, handling VAT, IoR, compliance, returns and payment processing. An MoR includes IoR. An IoR alone does not include MoR.

Does TikTok Shop check product compliance? Yes. TikTok Shop UK conducts compliance checks on listings and may request documentation including Declarations of Conformity, test reports and proof of a UK Responsible Person. Non-compliant listings are removed.
