Amazon UK Compliance 2026 — FNSKU, IEN, UKCA, CPSR

UKCA, GPSR, IEN, FNSKU, CPSR — Amazon's 2026 compliance bar is unforgiving, rejection reasons are often contradictory, and every day suppressed is revenue gone.

We assemble the documentation pack Amazon's reviewers actually accept — first time — and help get suppressed ASINs back live quickly.

The foundation principle

Most Amazon sellers do not have a traffic problem.They have a listing foundation problem.

Weak titles, poor images, unclear bullets, missing A+ Content and weak backend keywords quietly waste PPC spend, suppress conversion and erode account performance — long before traffic is the real issue.

Honest diagnostics

Compliance problems we fix every week

  • FNSKU labels missing or wrong ahead of the 31 March 2026 mandate — units risk being refused at the FC.
  • IEN (Importer Entry Number) not declared at shipment creation, blocking inbound bookings.
  • UKCA / CE marking missing or unevidenced on regulated goods, suppressing listings overnight.
  • Cosmetics live without a current CPSR or named UK Responsible Person on file.
  • Restricted-claim wording on supplements, medical or children's products triggering policy strikes.
  • Documentation pack (DoC, technical file, supplier invoices) scattered and not Amazon-ready.

Buyer fit

Who Amazon UK compliance support is for

  • UK Seller Central brands shipping FBA into a 2026-changed compliance environment.
  • Brands in regulated categories: toys, electronics, PPE, cosmetics, supplements, baby, machinery.
  • Sellers facing an active suppression notice citing UKCA, CE, CPSR or restricted claims.
  • Vendor Central (1P) suppliers whose chargebacks are tracking back to compliance gaps.
  • Importers needing IEN and FNSKU readiness ahead of the 2026 mandates.

Clear deliverables

What you receive

  • Listing-level compliance audit against current Amazon UK enforcement.
  • FNSKU label review and 2026 mandate-readiness check.
  • IEN process documentation aligned to HMRC import records.
  • UKCA / CE Declaration of Conformity drafting and review.
  • CPSR coordination with qualified safety assessors for cosmetics.
  • Restricted-claim copy rewriting on titles, bullets, A+ and imagery.
  • Suppression remediation pack and submission to Amazon UK.
  • Plain-English compliance log so your team knows what is on file and what expires when.

Most compliance remediations turn around in 5–14 days. We coordinate with qualified safety assessors and notified bodies where required — we do not provide legal advice.

Founder-led work

Every engagement is led by Billy personally — same brief, same writer, same eye on the listing from the audit through to release. Years of hands-on Seller Central and Vendor Central experience across UK Amazon brands, channelled into work that's reviewed by a named specialist rather than handed to a junior or a templated tool.

Why Compliance Keeps Failing

The real reasons listings get suppressed

Amazon's compliance review process is largely automated, opaque, and inaccessible. These are the specific failure patterns we see — and how we fix them.

Listings suppressed without warning

UK sellers report that almost every best-selling product has been suppressed at least once due to compliance issues. Amazon's automated review systems reject documentation with no explanation and no escalation path.

We audit your compliance documentation before submission, structuring it in the format Amazon's review teams actually accept.

Documents rejected repeatedly

Manufacturer documentation, test reports, and Declarations of Conformity are rejected even when they are technically valid. The reviewing team is inaccessible and the rejection reasons are contradictory.

We reformat, reframe, and resubmit your documentation with the supporting evidence and context that reduces rejection risk.

UKCA/CE marking confusion post-Brexit

Post-Brexit compliance requirements mean that products sold on Amazon UK may need UKCA marking, CE marking, or both — with different rules for different categories and transition periods causing widespread confusion.

We clarify the correct marking requirement for your specific product and category, and help you obtain the correct Declaration of Conformity.

IEN for FBA Imports — Ongoing Requirement

Import Entry Numbers have been required for all imported FBA shipments into Amazon UK since April 2024. Many sellers are still not aware this applies to them, or have not set up the correct documentation process. UK-domestically sourced stock is exempt.

We clarify whether the IEN requirement applies to your supply chain and help you implement the correct customs documentation process.

Cosmetics and health products flagged constantly

Cosmetic Product Safety Reports (CPSR), Responsible Person requirements, and labelling rules for health and beauty products are complex and frequently updated — leading to repeated listing suppressions.

We work with accredited safety assessors and help you obtain the CPSR and RP documentation needed to keep your cosmetic listings live.

FNSKU mandate and commingling end (March 2026)

Amazon UK ends Stickerless, Commingled Inventory from March 31, 2026. All FBA products must carry a unique FNSKU barcode. Sellers using commingling face disrupted shipments and additional per-unit labelling costs that can squeeze already tight margins on low-price products.

We audit your current FBA setup, identify which ASINs need FNSKU labelling, and help you plan the labelling transition before the March 31 deadline.

UK GPSR — General Product Safety Regulation (live Dec 2024)

The UK GPSR replaced the General Product Safety Directive in December 2024. It requires sellers to identify a UK responsible person, maintain traceability documentation, and ensure consumer-facing safety information is available. Many sellers are not aware the regulation changed.

We review your product listings against UK GPSR requirements, identify missing responsible person details, and help you implement the documentation structure needed for full compliance.
