Substance identity
Composition, impurities and analytical reports (for example NMR, IR, HPLC or GC) for each substance.
Your REACH Only Representative for non-EU substance manufacturers
Chinese manufacturers cannot register under REACH themselves. Either each EU importer registers the substance, or the manufacturer appoints an Only Representative in the EU to register once for all its importers.
| EU importer registers | Your Only Representative registers | |
|---|---|---|
| Who holds the registration | Each importer, separately | Your OR, on your behalf |
| Your composition data | Shared with each registering importer | Shared once, with your OR under a confidentiality-bound mandate |
| Changing customers | A new customer must register or you lose the sale | New EU customers are covered by your existing registration |
| Cost | Repeated by every importer | Paid once and reflected in your price |
Composition, impurities and analytical reports (for example NMR, IR, HPLC or GC) for each substance.
Which importers buy the substance and the annual tonnage to the EU.
How your customers use the substance, so the registration and SDS cover those uses.
Any test reports and your current SDS, which usually needs converting to the EU format.
Your OR keeps up-to-date information on the quantities imported and the customers supplied, updates the registration when things change, and keeps an eye on the Candidate List, restrictions and ECHA evaluation decisions that affect your substances.
No. Registration is done by an EU importer or by an Only Representative established in the EU and appointed by the Chinese manufacturer under Article 8.
For the quantities covered by the OR's registration, they become downstream users and do not need to register the substance themselves.
No. Chinese chemical rules and EU REACH are separate systems; the EU requires its own registration by an EU-established registrant.
The process your Only Representative runs.
Joining existing registrations.
What EU customers will ask for first.
