# UVCB substance analysis under REACH

## Call on the FILAB laboratory for your UVCB substance analysis needs in the context of REACH. A question? contact@filab.fr

### What is a UVCB substance?

The term “UVCB substance” stands for “**Substances of Unknown or Variable Composition, Complex Reaction Products and Biological Materials**“.

A UVCB substance is a substance of **unknown composition** resulting from complex reactions or biological materials.

### Why conduct a UVCB substance analysis?

The [REACH](https://echa.europa.eu/fr/regulations/reach/understanding-reach) registration process requires the submission of an application dossier to the European Chemicals Agency ([ECHA](https://echa.europa.eu/home)) detailing the identity of the substance. 

The identification of the substance in question is fundamental as it will determine the rest of the registration process.

It is therefore necessary to call upon a competent laboratory to analyse your UVCB substances in order to comply with the European **REACH regulation**.
