2904.34.00.00 - Potassium perfluorooctane sulfonate

This HTS code, 2904.34.00.00, specifically classifies Potassium perfluorooctane sulfonate. This compound is a salt derived from perfluorooctane sulfonic acid, characterized by its chemical structure where the hydrogen atoms of the octane sulfonate are replaced by fluorine atoms, and the counter-ion is potassium. It is a distinct chemical entity utilized in various industrial applications, often as a surfactant or processing aid due to its unique surface properties.

Distinguishing this category from its siblings, 2904.34.00.00 represents a specific potassium salt. It differs from 2904.31.00.00, which covers the parent perfluorooctane sulfonic acid itself, and from 2904.32.00.00 and 2904.33.00.00, which classify the ammonium and lithium salts, respectively. Furthermore, it is separate from 2904.35.00.00, designated for other salts of perfluorooctane sulfonic acid not specifically listed, and 2904.36.00.00, which pertains to perfluorooctane sulfonyl fluoride, a precursor compound.

As this HTS code represents a leaf node, there are no further subdivisions within this specific classification. Therefore, the focus remains on the precise identification of Potassium perfluorooctane sulfonate based on its chemical composition and its unique status as a potassium salt within the broader category of perfluorooctane sulfonic acid derivatives. Classification relies on confirming the presence of the perfluorooctane sulfonate anion and the potassium cation.
