9902.01.46 - Potassium fluoride hydrofluoride (CAS No. 7789-29-9) (provided for in subheading 2826.19.90)

HTS 9902.01.46 specifically classifies Potassium fluoride hydrofluoride, identified by its CAS Number 7789-29-9. This chemical compound, also known as potassium bifluoride, is typically a white crystalline solid. Its primary use often relates to its chemical properties, such as being a source of hydrofluoric acid or as a fluxing agent.

This particular HTS chapter, 99, is reserved for temporary legislation, modifications to trade agreements, and additional import restrictions. Therefore, HTS 9902.01.46 represents a specific, likely temporary, provision for this chemical. Unlike the preceding chapters (01xx, 02xx, etc.) which cover broad categories of goods like live animals, this chapter deals with administrative and regulatory controls rather than the inherent nature of the goods themselves. The classification "provided for in subheading 2826.19.90" indicates that absent this temporary provision, the substance would ordinarily fall under a more permanent HTS classification for inorganic fluorides.

As a leaf node, HTS 9902.01.46 does not have further subdivisions. Its inclusion within Chapter 99 signifies that its classification is driven by specific legislative actions or trade policy rather than a detailed breakdown of product types or chemical variations. When classifying Potassium fluoride hydrofluoride, importers must therefore consider not only the chemical identity but also any active temporary legislation or restrictions applicable at the time of import.
