On June 6, 2023, the Ministry of Ecology and Environment of China, in collaboration with relevant departments, issued the Announcement No. 20[2023] titled "Environmental Risk Management and Control Requirements for Five Types of Persistent Organic Pollutants Including Polychlorinated Naphthalene." This Announcement addresses strict control measures for six types of persistent organic pollutants (POPs), namely hexachlorobutadiene, polychlorinated naphthalene, pentachlorophenol and its salts and esters, decabromodiphenyl ether, and short-chain chlorinated paraffins. All these measures aim to prevent environmental pollution and safeguard human health and the ecosystem.
Major control measures:
-
The production, use, and import/export of hexachlorobutadiene, polychlorinated naphthalene, and pentachlorophenol and its salts and esters are prohibited;
-
The production, use, and import/export of decabromodiphenyl ether, with specific exemptions for textile products requiring flame retardancy (excluding clothing and toys) are prohibited; exemption is valid until December 31, 2023.
-
The production, use, and import/export of short-chain chlorinated paraffins is prohibited; nine applications are exempted from the prohibition measure including short-chain chlorinated paraffins used as additive in the production of conveyor belts in the natural and synthetic rubber industry. Exemption is valid until December 31, 2023.
-
Enterprises and entities emitting hexachlorobutadiene and polychlorinated naphthalene should take specific measures to reduce emissions or eliminate emission sources. Alternative technologies are encouraged to prevent the production and release of these pollutants.
-
Chemicals used for laboratory-scale research or as unintentional trace contaminants in products and articles serving as reference standard do not meet the above-mentioned requirements, unless otherwise specified.

This Announcement will come into effect from June 6, 2023. The Ministry of Ecology and Environment will coordinate with other departments to strengthen publicity and guarantee that companies and competent departments fully understand management requirements. Once there are violations, investigations will be conducted. This move marks an important step for China in the environment protection and control of POPs.
