9902.01.42 - Sodium Fluoride (CAS No. 7681-49-4) (provided for in subheading 2826.19.20)

This HTS category, 9902.01.42, specifically classifies Sodium Fluoride (CAS No. 7681-49-4) when imported under temporary legislation or special trade provisions outlined in Chapter 99 of the Harmonized Tariff Schedule. This provision is typically invoked for goods that may otherwise fall under a standard HTS classification but are subject to specific import restrictions or modifications, as indicated by its reference to subheading 2826.19.20.

Given its placement within Chapter 99, this category is distinct from the primary tariff headings that classify goods based on their inherent material composition and function, such as those found in Chapters 1 through 97. For example, while subheading 2826.19.20 would be the standard classification for Sodium Fluoride under Chapter 28, the use of Chapter 99 signifies a special import status or condition that overrides the general tariff treatment. This category serves as an exception or modification to standard customs procedures for this specific chemical.

As a leaf node, HTS category 9902.01.42 does not have further subdivisions. The classification of Sodium Fluoride under this temporary provision is definitive for goods imported under the specified trade agreements legislation or Section 22 of the Agricultural Adjustment Act. Importers must ensure they meet all requirements and conditions associated with this temporary classification, as it may involve specific duties, quotas, or documentation beyond those required for the standard tariff classification.
