Perfluorooctane Sulfonate Potassium Flake Form
Flake-form potassium perfluorooctane sulfonate for easy handling in chemical synthesis. Precisely matches HTS 2904.34.00.00 as the potassium salt of PFOS, a halogenated sulfonated hydrocarbon derivative. Chapter notes confirm classification for pure compounds regardless of physical form.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If nitrogen functions dominate over sulfonation
Chapter notes specify sulfonated derivatives stay in 2904 even with nitrogen groups.
If when imported as stabilized mixture with anticaking agents
Chapter 29 note (f) allows stabilizers only if necessary for transport, otherwise Chapter 38.

Import Tips & Compliance
• Use UN-approved chemical packaging; provide CAS number 2795-39-3 documentation
• Avoid generic 'fluorochemical' declarations to prevent reclassification

Potassium Perfluorooctane Sulfonate Powder
Pure potassium perfluorooctane sulfonate (PFOS-K) in powdered form, a fluorinated surfactant used in industrial applications. Classified under HTS 2904.34.00.00 as a sulfonated, halogenated derivative of hydrocarbons, specifically the potassium salt of perfluorooctane sulfonic acid. Meets chapter 29 requirements for chemically defined organic compounds with sulfonated and halogenated functions.
PFOS Potassium Salt Technical Grade 98%
Technical grade potassium perfluorooctane sulfonate with 98% purity, used in manufacturing fire-fighting foams and coatings. Falls under HTS 2904.34.00.00 due to its specific chemical identity as a perfluorooctane sulfonate salt. Exclusively covers chemically defined sulfonated/halogenated hydrocarbons per Chapter 29 notes.
High Purity PFOS-K for Research Use
Ultra-high purity (>99.5%) potassium perfluorooctane sulfonate for laboratory and research applications. Classified under HTS 2904.34.00.00 as it is a separate chemically defined compound per Chapter 29 note (a). Physical form (powder, crystal) does not affect heading.
Industrial Potassium Perfluorooctanesulfonate Crystals
Crystalline potassium PFOS for industrial wetting agent production, meeting purity specs for surfactants. HTS 2904.34.00.00 specifically covers this potassium salt as a perfluoroalkyl sulfonated derivative. Remains in Chapter 29 as chemically defined, not a preparation.
