UK Regulations

UK REACH Compliance: Post-Brexit Chemical Guide

When the UK left the EU's single market, it established an independent chemicals regulatory framework — UK REACH — enforced by the Health and Safety Executive (HSE) rather than ECHA. DEFRA has since estimated that full transition to the UK REACH model could cost British industry over £2 billion in duplicative testing, and in May 2024 the government published an Alternative Transition Model (ATR) proposal to reduce that burden by accepting certain EU REACH data. The registration deadlines have been extended to October 2026, 2028, and 2030 depending on tonnage band — but the fundamental requirement has not changed: EU REACH registrations have zero legal standing in Great Britain.

UK REACH is now a distinct regulatory framework governing chemicals placed on the Great Britain market. If your company moves chemicals, mixtures, or articles containing substances of very high concern (SVHCs) between the EU and the UK, you are navigating two separate regimes. On the Sustalium platform, UK-specific registration is the single most misunderstood requirement we see — companies consistently assume their EU REACH dossier covers the UK market, and they are consistently wrong.

UK Packaging Tax: Avoiding HMRC Fines

If your small business manufactures or imports goods into the United Kingdom, the product itself is no longer your only regulatory concern. The box, the plastic wrap, and even the tape holding it together are now subject to intense scrutiny under the UK Plastic Packaging Tax (PPT) and the Extended Producer Responsibility (EPR) framework.

Many MSMEs assume these taxes only apply to massive retail giants. This misconception is leading to devastating financial penalties.

UKCA Declaration of Conformity: Complete UK Guide

In March 2026, the UK government published updated guidance reaffirming that CE marking remains accepted in Great Britain until December 2027, with UKCA becoming mandatory from January 2028. The Product Regulation and Metrology Act 2025 also introduced Fast-Track UKCA, allowing manufacturers to use EU conformity assessment procedures to apply the UKCA mark. Despite this flexibility, many manufacturers still struggle with the transition because the legal references are fundamentally different — UK Statutory Instruments instead of EU Directives.

Most manufacturers assume a UKCA Declaration of Conformity is just a CE DoC with the logo swapped. It is not. We help electronics and machinery clients transition from CE to UKCA on the Sustalium platform, and the UK statutory instrument mapping is consistently the part that trips teams up.

For goods placed on the market in Great Britain, the UKCA (UK Conformity Assessed) marking replaces the European CE Mark. The legal backbone is the UKCA Declaration of Conformity (DoC) — a formal legal document signed by the manufacturer stating the product complies with all relevant UK statutory instruments. If British Trading Standards audit your product, this is the first document they request.
