Restrictions are designed to protect human health and the environment from unreasonable risks posed by chemicals. Restrictions typically limit or prohibit the manufacture, marketing (including import) or use of a substance. Depending on the circumstances, certain conditions, such as technical measures or labelling, may also be imposed.
A restriction may apply to the substance as such or to a substance contained in a mixture or an article, including substances that are not subject to authorisation, such as substances manufactured or imported in quantities of less than one tonne per year, or certain polymers.
The REACH restriction does not apply to on-site isolated intermediates, to substances used for research and development, or to substances that only pose a risk to human health when used in cosmetics.
