9902.01.25 - Dihydrogen hexafluorozirconate(2-) (Hexafluorozirconic acid) (CAS No. 12021-95-3) (provided for in subheading 2811.19.61)

This HTS category, 9902.01.25, specifically addresses Dihydrogen hexafluorozirconate(2-), also known as Hexafluorozirconic acid. It is important to note that this classification is located within Section XXII of the Harmonized Tariff Schedule, which pertains to Special Classification Provisions, Temporary Legislation, and Temporary Modifications. This particular subheading is provided for under the more general classification of inorganic acids and other nonmetals, specifically subheading 2811.19.61, but is designated here for specific temporary or special import considerations.

As a leaf node within the HTS database, this category does not have further subdivisions. Its distinctiveness lies in its specific chemical identity and its placement under Chapter 99, which signifies special trade provisions rather than the standard classification of goods based on their primary material or function found in earlier chapters. Therefore, any product classified under 9902.01.25 would be Dihydrogen hexafluorozirconate(2-) that is subject to the specific temporary legislation or trade agreement modifications referenced by this code.

The practical classification criteria for this entry revolve around the precise chemical compound and its presence in shipments subject to the special provisions outlined in Chapter 99. This distinguishes it from other chemical compounds or products that may fall under broader categories within Chapters 1-97 of the HTS, which are not subject to these specific temporary legislative or trade agreement-based restrictions.
