Manufacturers and importers must gather detailed information on the substances they produce or import into the EU in quantities of one tonne or more per year.
This information will be used to register the chemical substance with the European Chemicals Agency (ECHA). The registration will identify uses for the chemical substance. For substances manufactured or imported in quantities of more than 10 tonnes per year, information must be supplied to demonstrate that they are safe for the identified uses.
You must register new substances before you put them on the market at 1 tonne per annum or greater. Failure to register means the substance can't be manufactured or imported into the EU in quantities of one tonne or more per year. For existing substances, pre-registering a chemical substance means that a manufacturer or importer may be able to take advantage of phased deadlines for full registration.
Pre-registration
Pre-registration is only available if it is the first time that the chemical substance is being manufactured or imported into the EU in quantities of one tonne or more per year.
By pre-registering chemicals you can delay full registration, depending on the quantities and types of chemical substances you deal with.
