About HS Code 290434
This HS code specifically covers Potassium Perfluorooctane Sulphonate (KPFOS), a salt of Perfluorooctane Sulphonic Acid (PFOS). KPFOS, like other PFOS derivatives, was historically valued for its exceptional surfactant properties, providing effective water and oil repellency. Its applications spanned various industrial sectors, including as a component in fire-fighting foams (AFFF), in metal plating baths, and in certain textile and paper treatments to impart stain and water resistance. However, due to its environmental persistence, bioaccumulation, and potential health concerns, KPFOS is now subject to severe international restrictions and bans under the Stockholm Convention. Global trade in KPFOS is highly regulated, with most nations having phased out its production and use. Any remaining trade is typically for very specific, approved critical applications or for managing existing stockpiles. Importers and exporters must navigate complex international chemical regulations and demonstrate compliance with strict environmental and safety standards.
Products Under This Code
Potassium perfluorooctane sulfonate, KPFOS-containing fire suppression agents, KPFOS-based wetting agents, KPFOS for specialized industrial coatings, KPFOS in photographic emulsions
Real World Examples
3M (historical producer), Chemours (fluorochemicals, but KPFOS largely restricted), Daikin (fluorochemicals, but KPFOS largely restricted)
Common Misclassification
Often confused with other PFOS salts (e.g., 290432 for ammonium salt, 290433 for lithium salt) or with PFOS acid itself (290431), requiring precise chemical identification for correct classification.
Products Classified Under 2904.34
Industry
This code belongs to the Chemicals industry.
Trade Overview
Trade is severely restricted globally, with limited movements primarily for specific exempted uses or existing stock management, often involving countries like China and EU member states under strict regulations.
