Guidance for monomers and polymers

Polymers are the material of choice in a vast range of applications such as
packaging, in building and construction, in transportation, electrical and
electronic equipment, in agriculture, as well as in the medical and the sports
sectors. The versatility of polymeric materials is due to the fact that the
physico-chemical properties of polymers can be tailored by a careful adjustment
of the composition and molecular weight distribution of the molecules
constituting the polymer.

Owing to the potentially extensive number of different polymer substances on
the market, and since polymer molecules are generally regarded as representing
a low concern due to their high molecular weight, this group of substances is
exempted under REACH from registration and evaluation. Polymers may however
still be subject to authorisation and restriction.

However, manufacturers and importers of polymers may be required to register
the monomers or other substances ending up as building blocks of the polymer,
as these molecules are generally recognised as of higher concern than the
polymer molecule itself.

An recently updated document describes the specific provisions for polymers and
monomers under REACH. It is part of a series of guidance documents that are
aimed to help all stakeholders with their preparation for fulfilling their
obligations under the REACH regulation. These documents cover detailed guidance
for a range of essential REACH processes as well as for some specific
scientific and/or technical methods that industry or authorities need to make
use of under REACH.

The guidance documents were drafted and discussed within the REACH
Implementation Projects (RIPs) led by the European Commission services,
involving stakeholders from Member States, industry and non-governmental
organisations.
