On 3 April 2017, Japan designated 16 further substances as Priority Assessment Chemical Substances (PACs) under the Japan Chemical Substances Control Law (CSCL). In addition, the designation of 11 substances as PACs was cancelled pursuant to Article 11 of the CSCL. This brought the number of PACs to 201. PACs are substances suspected of causing long term toxicity to humans, flora or fauna. Manufacturers and importers of PACs in volumes ? 1 tonne/year are required to report specific data, including production, shipment or import volumes, each calendar year.
