The Classification and Labelling (C&L) Inventory is a database maintained by the European Chemicals Agency (ECHA). The C&L Inventory lists classifications and labelling elements of dangerous substances placed on the market in the European Union (EU) by manufacturers or importers. Classifications and labelling elements of pure substances must be notified. The legal basis for the obligation to notify classifications and labelling elements to ECHA is set out in the CLP Regulation (Articles 39 to 41). The C&L Inventory is publicly accessible.
The ECHA website states explicitly that ECHA does not verify the accuracy of the information in the C&L Inventory. The C&L Inventory now contains numerous different classifications for most substances. Possible reasons for this include impurities or additives, and the form or physical state in which the substance was placed on the market. However, the possibility cannot be excluded of incorrect classifications also being reported to the C&L Inventory by manufacturers/importers owing to a lack of data or information.
The reasons for discrepancies in classifications and labelling elements of a substance cannot normally inferred from the C&L Inventory. If you are looking for information on the classification and labelling of pure substances, you are therefore advised to use the data in the C&L Inventory with caution and, where possible, also to consult other sources.
