9902.01.43 - Tin fluoride (CAS No. 7783-47-3) (provided for in subheading 2826.19.90)

This HTS classification, 9902.01.43, specifically addresses Tin Fluoride (CAS No. 7783-47-3). While the broader Chapter 99 pertains to temporary legislation and special provisions, this particular subheading is designated for a specific chemical compound, Tin Fluoride, which is otherwise provided for under subheading 2826.19.90. This indicates that while its primary tariff treatment would fall under the chemical classifications of Chapter 28, this entry in Chapter 99 signifies a unique temporary modification or restriction applicable to its importation.

Distinguishing this category from its siblings within Chapter 99 is crucial. The other entries in Chapter 99, such as those for live animals (e.g., 0101, 0102, 0103), relate to entirely different subject matters, primarily focused on temporary import restrictions or modifications applied to agricultural goods or specific trade agreements. Category 9902.01.43, however, is dedicated solely to a particular chemical substance and its associated temporary regulatory treatment, rather than a broad class of goods.

As this is a leaf node within the HTS database, there are no further subcategories. Therefore, classification within 9902.01.43 hinges on the precise identification of the imported merchandise as Tin Fluoride, as confirmed by its CAS number (7783-47-3) and its reference to the primary classification in 2826.19.90. Importers must consult the specific legislative notes and proclamations associated with this Chapter 99 subheading to understand the exact nature of the temporary modification or restriction in effect.
