9902.01.69 - Silver sodium zirconium hydrogenphosphate (CAS No. 265647-11-8) (provided for in subheading 2843.29.01)

HTS 9902.01.69 specifically classifies Silver sodium zirconium hydrogenphosphate, identified by CAS No. 265647-11-8. This designation is made within Section XXII of the Harmonized Tariff Schedule, which pertains to special classification provisions and temporary legislation, including restrictions enacted under Section 22 of the Agricultural Adjustment Act. Therefore, this category is reserved for a very specific chemical compound, not for general categories of goods.

Unlike the broader sibling categories at the root level, which cover large classes of live animals such as horses, bovine animals, swine, sheep, goats, and poultry, HTS 9902.01.69 deals with a single, precisely defined inorganic chemical substance. Its inclusion under Chapter 99 signifies that its import is subject to specific temporary measures or restrictions, distinct from the standard classification of goods found in Chapters 1 through 97.

As this HTS code represents a leaf node within the tariff schedule, there are no further subcategories under 9902.01.69. The classification is definitive for Silver sodium zirconium hydrogenphosphate, which is further clarified by its reference to subheading 2843.29.01, indicating its broader chemical classification before the application of temporary trade provisions. Importers should consult specific trade notices and regulatory requirements associated with Chapter 99 when importing this substance.
