Q Can downstream users continue to use a substance, if it has not been (pre-)registered?

Downstream users can use substances, irrespectively of whether they have been (pre-)registered or not. In this regard use means any processing, formulation, consumption, storage, keeping, treatment, filling into containers, transfer from one container to another, mixing, production of an article or any other utilisation. Placing on the market is however not to be regarded as a use. Q&A 40 explains the need for substances to be (pre-)registered in order to be placed on the market.

Please note that for the use of substances (whether (pre-)registered or not) certain requirements related to restrictions, authorisation and risk management may apply. Guidance on how to comply with these requirements is provided in the Guidance for downstream users available on the ECHA website at:
