Chemical classification

Chemical classification means finding out whether the chemicals you supply can harm you, others or the environment.

Classification is important because it provides the starting point for the controls needed to protect people and the environment.

This guidance is to help you understand the basics of classification and where you can find detailed help and advice.

The law

The classification of chemicals placed on the market in Great Britain (England, Scotland and Wales) are regulated by the GB Classification, Labelling and Packaging Regulation, known as GB CLP.

HSE is the GB CLP Agency and carries out certain CLP functions formerly undertaken by ECHA.

Supply chemicals to the GB market

If you are:

• a GB-based manufacturer, importer, downstream user or distributor (known as a GB-based supplier) supplying chemicals to the GB market
• an NI-based manufacturer, downstream user or distributor (known as an NI-based supplier) directly supplying chemicals to the GB market

you have a legal duty to understand your obligations and duties under the GB CLP Regulation.

If your business is based in Great Britain and is supplied by businesses based within the EU or European Economic Area (EEA) and you place those products on the GB market, you are defined as an importer of chemicals and must comply with the GB CLP Regulation.

Supply chemicals to the NI market

The classification of chemicals placed on the market in Northern Ireland are regulated by European regulations known as EU CLP. HSE Northern Ireland (HSENI) has separate guidance on EU CLP.
