Staying compliant after registration
A registration number is a starting position, not a finish line. The obligations that follow it are continuous, they apply whether or not anyone is asking, and most enforcement activity concerns them rather than registration itself.
Keeping the dossier current
A registration must be updated without undue delay when circumstances change. The triggers are specific:
| Trigger | Action | Timing |
|---|---|---|
| Tonnage band increase | Submit the additional information for the higher band | Before exceeding the threshold |
| New hazard information | Update classification, dossier and safety data sheet | Without undue delay |
| New identified use | Add the use and its exposure scenario | Before supplying for that use |
| Change in composition | Reassess substance identity; the registration may not cover the new material | Before placing on the market |
| Change of registrant status | Update role, legal entity or contact details | Without undue delay |
| Ceasing manufacture or import | Notify HSE | Without undue delay |
| HSE decision | Comply with the requirement stated | By the deadline in the decision |
Safety data sheets for the GB market
A GB safety data sheet is not an EU safety data sheet with the address changed. It must reflect GB CLP classification, GB legislation references, GB exposure limits and a GB emergency contact.
- Supply an SDS with the first delivery of any hazardous substance or mixture, and for candidate list substances.
- Update it without delay when new information affecting risk management becomes available, or when a restriction or authorisation is imposed.
- Supply the updated version free of charge to everyone who received the substance in the previous 12 months.
- Annex the relevant exposure scenarios where a chemical safety report was required.
- Use the section structure and content required for the GB market, in English.
The most common finding in a GB inspection
Safety data sheets that still carry EU legislation references, EU classification and a European emergency number, issued for material placed on the GB market. It is visible on the face of the document and it is trivially easy for an inspector to identify.
GB CLP runs independently
Classification, labelling and packaging is a separate regulation with its own duties, and they apply regardless of registration status or tonnage — there is no one tonne threshold for classification.
- Classify substances and mixtures against GB CLP criteria.
- Apply the GB mandatory classification list where an entry exists — this list diverges from EU Annex VI.
- Label and package to GB requirements for material supplied in Great Britain.
- Notify classification and labelling to HSE where required.
- Review classification when new hazard information arrives.
Downstream user duties
Buying inside GB does not make you unregulated. If you use a substance industrially or professionally, you must:
- Use it within the conditions of the exposure scenario supplied with the safety data sheet.
- Implement the risk management measures the scenario specifies.
- Tell your supplier if your use is not covered, so it can be added — or prepare your own downstream user chemical safety report and notify HSE.
- Pass information up the chain where you hold new hazard data.
- Pass safety information down the chain to your own customers.
Records and enforcement
Information required under UK REACH must be kept for at least ten years after you last manufacture, import, supply or use the substance. In practice that means volume records, safety data sheets, customer lists and the evidence behind any exemption you rely on.
Enforcement in Great Britain sits with HSE, the Environment Agency and their devolved equivalents, alongside local authorities and Border Force at the point of import. Powers include improvement and prohibition notices, seizure and destruction, prosecution, and — most disruptively in commercial terms — revocation of a registration, which stops market access immediately.
A practical annual routine
Once a year: confirm tonnage against band, check every substance against the current GB candidate, authorisation and restriction lists, review safety data sheets for legislative currency, verify that identified uses still match how customers actually use the material, and re-confirm the basis of any exemption you rely on. Most non-compliance we find is a year or two of drift, not a decision.
