UNITED KINGDOM / CHEMICAL REGULATION
Map chemical supply-chain responsibilities in Great Britain, assess substance registration and use-related duties, and prepare a documented UK REACH approach that remains distinct from EU REACH registrations and Northern Ireland requirements.

01 / THE BIG PICTURE
UK REACH governs chemicals in Great Britain and is administered by the Health and Safety Executive. It covers substances on their own, in mixtures and in articles, with obligations that vary by supply-chain role, substance, use and quantity.
An EU registration is not a substitute for assessing UK REACH duties. A business that previously relied on an EU supplier may have a different role when importing into Great Britain. The starting point is an accurate flow of substances and legal entities, rather than a request for a generic REACH certificate.

Start with your product’s intended use and category. Here are some of the applications covered in this service.
Map substance identity, annual quantities and intended uses.
Review constituent substances and importer responsibilities.
Assess relevant substance and communication obligations.
These are examples. The applicable route depends on your product specifications and target market.
03 / THE PATH FORWARD
Move from the first assessment to a documented compliance plan, with clear responsibilities and evidence for your product.
Identify the GB entity and supply-chain arrangement.
Review quantities, exemptions and regulatory status.
Resolve inquiry, data and registration requirements.
Track supply, composition and use changes.

Map the GB manufacturer, importer, downstream user and distributor for each supply route. Record who brings substances into Great Britain and whether a qualifying Only Representative arrangement applies. One business can hold several roles across its portfolio, so a single company-wide classification may miss important obligations.
Registration generally concerns substances manufactured or imported at one tonne or more per year per legal entity, subject to applicable exemptions. Mixtures are not registered as mixtures; their constituent substances must be considered. Aggregate substance quantities across relevant products instead of reviewing each purchase order in isolation.
For a new registration, HSE describes an Article 26 inquiry before engagement in the registration and data-sharing process. Determine what information is available and who can lawfully use it. Existing EU study summaries or supplier files should not be assumed to come with transferable data rights.
Transitional arrangements can depend on earlier supply history and the eligibility of the relevant business. Do not treat a notification as a universal registration or assume an old deadline applies to a new substance route. Check the current HSE position for the particular entity and substance.
Registration is one part of UK REACH. Restrictions, authorisation and supply-chain communication can affect a substance or use even where a registration threshold is not reached. Review the actual intended uses and information provided to customers, including safety data sheets where required.
Create a substance inventory linked to suppliers, tonnage estimates, uses and regulatory decisions. Flag new imports, changed compositions and increased quantities before purchase commitments are made. An assigned review process helps prevent procurement substitutions from silently changing the company’s UK REACH position.
Try “testing”, “documents” or “process”.
Requirements vary by product, intended use and market. Confirm the applicable standards and current regulatory route before proceeding.
05 / A LITTLE MORE CLARITY
Practical answers to common questions about UK REACH.
No. Assess UK REACH separately, including any valid transitional or representative arrangements.
No. Registration concerns constituent substances and relevant aggregated quantities.
A qualifying non-GB manufacturer, formulator or article producer may appoint a GB-based Only Representative under the applicable provisions.
No. Other UK REACH requirements can apply independently of the registration tonnage threshold.
