China looks at the domestic production and use of long-chain PFCAs and medium-chain chlorinated paraffin.

The Stockholm Convention’s POPRC19 will review 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) on July 20, 2023, according to a notice from China’s Ministry of Ecology and Environment. The data collection process will continue 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 percent 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).
