The global ban on the production and use of perfluorooctanoic acid and its salts and related compounds has taken effect in more than 160 countries. The ban includes approximately 150 substances related to PFOS. It was agreed on under the United Nations "Stockholm Convention on Persistent Organic Pollutants" and entered into force for most of the 184 parties to the Convention. .
The countries that have not yet implemented the ban include:
Japan that cannot accept the amendment and 18 countries that have special agreements with the Convention, including Argentina, China, India, South Korea and Russia.
In addition, the United States, Israel, and Malaysia are not parties to the convention, so the ban does not apply to them.
The convention approved several five-year ban exemptions when it reached an agreement in May 2019, including:
Fire-fighting foam, coatings for film, invasive and implantable medical devices, manufacturing of fluoropolymers, manufacturing of plastic parts for automotive interiors, etc.
