9902.01.38 - Hydrazine, 64 percent solution in water (CAS No. 302-01-2) (provided for in subheading 2825.10.00)

This HTS classification, specifically 9902.01.38, pertains to Hydrazine, a solution containing 64 percent of this chemical compound in water. Hydrazine (CAS No. 302-01-2) is a highly reactive inorganic compound with a variety of industrial applications, including as a reducing agent, a propellant, and in the synthesis of other chemicals. This particular entry is "provided for in subheading 2825.10.00," indicating that it falls under the general classification for hydrazine and its inorganic compounds.

Chapter 99 of the Harmonized Tariff Schedule is dedicated to temporary legislation, temporary modifications proclaimed pursuant to trade agreements, and additional import restrictions. Therefore, HTS code 9902.01.38 represents a specific temporary provision or restriction applied to hydrazine solutions of this concentration. It is crucial to understand that this code operates within the framework of Chapter 99, meaning its application is contingent on specific legislative or proclamation events, and it often modifies or supplements the standard classification found in Chapters 1-98.

As this is a leaf node, there are no further subcategories within 9902.01.38. Its distinctiveness from sibling categories at the Chapter 99 level lies in its specific reference to a 64 percent solution of hydrazine. Other potential entries within Chapter 99 might address different chemical compounds, different concentrations of hydrazine, or other types of temporary trade measures. The classification hinges on the precise chemical identity and concentration of the imported substance, as well as the specific trade provisions enacted under Chapter 99.
