Substance Information Sheet (SIS)
A REACH registrant is required to produce and provide a safety data sheet (SDS) if the substance put on the EU market is:
(a) classified as hazardous under the CLP Regulation (1272/2008/EC) or as dangerous under the Dangerous Substances Directive (67/548/EEC); or
(b) it is persistent, bioaccumulative and toxic (PBT), or very persistent and very bioaccumulative (vPvB) as defined in Annex XIII of the REACH Regulation; or
(c) the substance is included in the European Chemicals Agency’s (ECHA) Candidate List of substances of very high concern.
You can find the candidate list on ECHAs website at the following link : http://echa.europa.eu/chem_data/authorisation_process/candidate_list_table_en.asp
If the substance does not meet any of the above criteria it is not mandatory to produce a SDS.
In such cases, and if agreed with the supply chain, a voluntary Substance Information Sheet (SIS) can be provided if absolutely necessary. This is not a mandatory requirement hence there is no prescribed format.
