China investigates domestic production and usage of medium-chain chlorinated paraffin and long-chain PFCAs 
On July 20, 2023, the Ministry of Ecology and Environment of China issues a notice to start collecting information on the production, uses, import/export, alternative substances and alternative technologies of “long-chain perfluorocarboxylic acids and their salts and related compounds” (long-chain PFCAs) and “medium-chain chlorinated paraffin” (MCCPs), which will be reviewed at the nineteenth meeting of the POPs Review Committee (POPRC19) of the Stockholm Convention. The information collection will last until August 27, 2023.
Chemicals seeking information
- Long-chain perfluorocarboxylic acids and their salts and related compounds
According to the draft risk management evaluation released by the POPRC19 of the Stockholm Convention on July 4, 2023, the long-chain PFCAs are recommended for consideration by the Conference of the Parties for listing in Annexes A-Elimination with specific exemptions.
- Medium-chain chlorinated paraffin (Chlorinated paraffins with carbon chain lengths in the range C14-17 and chlorination levels at or exceeding 45 per cent chlorine by weight)
According to the draft risk management evaluation released by the POPRC19 of the Stockholm Convention on July 4, 2023, MCCPs are recommended for consideration by the Conference of the Parties for listing in Annexes A-Elimination to the Convention with specific exemptions, and a specified concentration limit for the level of these components in other chlorinated paraffin commercial products.
Information to be collected
- Production and uses (production volume, usage volume and purpose of use, etc.)
- Alternative substances and alternative technologies (introduction of alternative products and alternative technologies, substitution costs and substitution effects).
