Registration is the key component of REACH. It is compulsory to register substances manufactured in or imported into the EU according to a volume-triggered system. Failure to register a substance for a specific tonnage band by the deadlines stated in the REACH text means that the substance cannot be manufactured or imported at that tonnage band after the deadline.
The European Chemicals Agency (ECHA) is responsible for managing the Registration system, receiving and reviewing registration dossiers and developing guidance to assist producers, importers and the competent authorities in implementing these provisions.
Downstream users of a chemical need to communicate with manufacturers or suppliers to make sure that the use they intend for the chemical has been assessed and concluded to be safe. If not, the downstream user will have to perform its own safety assessment and report to the Agency.
