Registration is when you submit documentation to ECHA which shows that the substance you deal with is handled safely throughout the supply chain, ensuring that human health and the environment are protected.
The documentation you need to submit depends on the volume of the substance you put on the market, the hazards of the substance, and whether or not the substance is only used as an intermediate in the manufacture of another substance under strictly controlled conditions.
The documentation needs to be provided in a registration dossier. The registration dossier includes a description of the uses of the substance, the physico-chemical, ecotoxicological and toxicological properties, and a hazard and risk assessment showing how the risks posed by the use of the substance are controlled.
Registrations are submitted in a IUCLID format through a tool called REACH-IT. In most cases, you need to pay a registration fee.
Each substance needs its own registration. If you deal with mixtures of substances, such as detergents and paints, or articles releasing substances, you need to register the different substances that are in the mixture or article.
You also need to identify and name your substances according to the same rules and criteria, so you can see if your substances are the same as in other companies. If this is the case, you need to register together.
