REACH registration step by step
What registration of each substance involves.
Your REACH Only Representative for non-EU substance manufacturers
REACH registers substances, but most exports to the EU are mixtures, polymers or finished articles. Here is how the obligations translate for each.
A mixture is not registered as such. Each substance in it is registered by the EU importer (or by an Only Representative appointed by the non-EU formulator) once the substance reaches 1 tonne per year. A non-EU company that formulates mixtures can appoint an OR for the substances in its mixtures, so its EU customers do not have to register them.
Polymers are exempt from registration (Article 2(9)). However, the monomers and other substances that form the polymer must be registered if the polymer consists of 2% by weight or more of them in the form of monomeric units and chemically bound substances, and their total quantity reaches 1 tonne per year (Article 6(3)) - unless those monomers have already been registered by an actor up the supply chain.
Registration is only one part of REACH. Annex XVII restricts certain substances in specific uses (for example PAHs in rubber and plastic parts), and substances on the Authorisation List (Annex XIV) cannot be used in the EU without an authorisation after their sunset date. Check both lists for every substance in your products.
No. The substances in the mixture are registered individually, each from 1 tonne per year, by the EU importer or by an Only Representative of the non-EU formulator.
Polymers are exempt from registration, but their monomers and other reacted substances must be registered when they make up 2% or more of the polymer and reach 1 tonne per year, unless already registered up the supply chain.
If an article contains a Candidate List substance above 0.1% by weight, suppliers must provide information for safe use (Article 33). Notification to ECHA applies above 1 tonne per year per producer or importer (Article 7(2)).
