§2.2 Information on composition, properties and waste management of substances/ mixtures becoming waste

For substances and mixtures that are classified as hazardous according to CLP, as also for non-classified mixtures containing hazardous substances above certain thresholds, a SDS need to be provided by the supplier. SDS have to fulfil certain requirements and comply with a format defined in Article 31 of the REACH Regulation, and must include information: — on the classification of the substance or mixture in accordance with Title II of CLP Regulation (section 2 of the SDS); this may be a harmonised classification or a self-classification (see Section 2.1); — on the composition / the ingredients (section 3 of the SDS); — on ‘disposal considerations’ (section 13 of the SDS); — on exposure scenarios (in the Annex). With this information available, the SDS can be a useful information tool for the further assessment steps that have to be carried out during classification according to the LoW once a particular product has become waste. Note that in case the product becoming waste is a mixture of two or more substances (e.g. a pot of varnish), the classification information for mixtures is a valuable source of information in general and secondly the classifications of the individual component substances must be used, rather than the overall chemical classification of the mixture. Section 3 of a SDS for mixtures provides the classifications according to CLP for the individual hazardous constituents of the mixture. This information may be validated or complemented by means of a search in the C&L inventory (cf. Section 2.1.3). Note that for substances and mixtures for which a SDS is not mandatory as well as also in the case of articles, voluntary product information sheets may be available that are not conforming to SDS but can provide information on composition and recommended disposal practices. Additional checks are recommended where either: — the information provided may be out of date (a product is discarded considerable time after it was last supplied); — there is any reason to believe the information is incomplete, inadequate, or inaccurate. — information on the waste-generating process suggests that additional substances (e.g. contaminants) may be present in the waste which are not covered by SDS.
