One key aspect of REACH is to improve communication in the supply chain. An increased amount of available information will ensure Downstream Users (DUs) of substances and mixtures have some assurance that how they use those chemicals is appropriate. It will also ensure that suppliers of chemicals do not propose uses that are not fit for purpose.

This short guide aims to provide some background as to why such communication is important. Once the reasons are understood, the level of information passed through the supply chain can be measured according to its relevance for understanding and controlling risk. A simple rule is that for low hazard substances, generic use information will probably suffice, but for substances of greater hazard, especially those of very high concern (SVHCs), considerable detail for exposure may be necessary. Conversely, substances with high exposure may need additional data, but for those with low exposure less comprehensive information may suffice.
