Overview
This HTS category, 9902.11.39, covers a specific chemical compound identified by CAS No. 200295-51-8. It is a polymer formed from hexanedioic acid, dihydrazide, 5-amino-1,3,3-trimethylcyclohexanemethanamine, 1,3-butanediol, and 1,1'-methylenebis[4-isocyanatocyclohexane]. The compound is further modified with methyl ethyl ketone oxime and polyethylene glycol mono-methyl ether blocking agents, and is presented in an aqueous solution. Its classification is specifically provided for under subheading 3909.50.50, indicating its primary nature as a synthetic polymer.
This category operates within Chapter 99 of the Harmonized Tariff Schedule, which is dedicated to temporary legislation, trade agreement modifications, and special import restrictions. Unlike the substantive chapters (01-97) that classify goods based on their inherent characteristics and function, Chapter 99 provisions are dynamic and subject to change based on trade policy. Therefore, 9902.11.39 is distinguished from sibling categories within Chapter 99 by the specific chemical identity and form of the product, as well as its designated reference subheading in the main body of the tariff schedule. It is not a direct comparison of goods by function or material in the way that siblings in Chapters 01-97 would be.
As a leaf node within the HTS classification system, 9902.11.39 has no further subcategories. Its detailed description and reference to subheading 3909.50.50 serve to uniquely identify this particular chemical product for import and export purposes under the specific provisions of Chapter 99. Classification at this level is critical for ensuring compliance with any applicable temporary tariffs, quotas, or other trade measures that may be enacted under this chapter.
