9902.10.60 - Sodium ethylate (sodium ethanolate) (CAS No. 141-52-6), solution in ethanol (CAS No. 64-17-5) (provided for in subheading 3824.99.92)

HTS code 9902.10.60 specifically classifies solutions of sodium ethylate (also known as sodium ethanolate) in ethanol. This classification is reserved for temporary tariff modifications and is provided for in subheading 3824.99.92, indicating it is a separate chemical product not elsewhere specified. The key characteristic for this classification is the presence of both sodium ethylate as the primary active component and ethanol as the solvent.

This particular HTS code exists within Chapter 99, which pertains to temporary legislation and modifications. Unlike the primary goods in Chapters 1 through 98 of the HTS, which describe tangible products based on their inherent characteristics and uses, Chapter 99 codes are dynamic and subject to change based on trade agreements, specific economic policies, or temporary import restrictions. Therefore, this code is distinct from sibling categories within Chapter 99 that might cover other temporary tariff adjustments for different classes of goods.

As a leaf node, HTS code 9902.10.60 does not have further subcategories. Classification under this heading is definitive for a solution of sodium ethylate in ethanol when imported under specific, temporary tariff provisions. Importers should be aware that the underlying substance, sodium ethylate, might have a different classification if not presented as a solution in ethanol and subject to different tariff treatment under the primary HTS chapters.
