About HS Code 290433
This HS code specifically identifies Lithium Perfluorooctane Sulphonate (LiPFOS), another salt derived from Perfluorooctane Sulphonic Acid (PFOS). Similar to other PFOS derivatives, LiPFOS was historically utilized for its unique surfactant properties, offering excellent water and oil repellency. Its applications included specialized industrial coatings, certain types of fire-fighting foams, and as a component in specific electronic manufacturing processes where its chemical stability and surface-active properties were advantageous. However, due to the recognized environmental persistence, bioaccumulation, and potential toxicity associated with PFOS and its salts, LiPFOS is now subject to stringent international regulations, including bans and restrictions under the Stockholm Convention. Consequently, global trade in LiPFOS is extremely limited, primarily confined to specific, critically exempted uses or for the management of existing stockpiles. Importers and exporters must adhere to strict international chemical control regulations and provide thorough documentation for any permitted transactions.
Products Under This Code
Lithium perfluorooctane sulfonate, LiPFOS-based surface treatment agents, LiPFOS in specialized lubricants, LiPFOS for specific electronic applications, LiPFOS in fire retardant formulations
Real World Examples
3M (historical producer), Chemours (fluorochemicals, but LiPFOS largely restricted), Daikin (fluorochemicals, but LiPFOS largely restricted)
Common Misclassification
Can be easily confused with other PFOS salts, such as ammonium (290432) or potassium (290434) perfluorooctane sulphonate, necessitating precise chemical identification to ensure correct classification.
Products Classified Under 2904.33
Industry
This code belongs to the Chemicals industry.
Trade Overview
Global trade is highly restricted, with limited imports/exports primarily for specific exempted uses or existing stock management, often involving countries like China and EU member states under strict regulations.
