About HS Code 290432
This HS code specifically covers Ammonium Perfluorooctane Sulphonate (APFOS), a salt of PFOS. Like PFOS itself, APFOS is a synthetic fluorinated compound that was historically valued for its excellent surfactant properties, making it effective in reducing surface tension. It found applications in various industrial processes, including as a wetting agent in metal plating, a component in fire-fighting foams (AFFF), and in certain textile and paper treatments to impart water and oil repellency. However, due to its environmental persistence, bioaccumulation, and potential health concerns, APFOS is subject to severe international restrictions and bans under the Stockholm Convention. Global trade in APFOS is now 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
Ammonium perfluorooctane sulfonate, APFOS-containing fire suppression agents, APFOS-based wetting agents, APFOS for specialized industrial coatings, APFOS in photographic emulsions
Real World Examples
3M (historical producer), Chemours (fluorochemicals, but APFOS largely restricted), Daikin (fluorochemicals, but APFOS largely restricted)
Common Misclassification
Often confused with other PFOS salts (e.g., 290433 for lithium salt, 290434 for potassium salt) or with PFOS acid itself (290431), requiring precise chemical identification for correct classification.
Products Classified Under 2904.32
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.
