9902.10.14 - (2-Chloroethyl)trimethylammonium chloride (CAS No. 999-81-5) (provided for in subheading 3808.93.50)

This HTS classification pertains to (2-Chloroethyl)trimethylammonium chloride, also known by its CAS number 999-81-5. While the primary description indicates it is provided for under subheading 3808.93.50, which deals with pesticides and similar products, this specific entry under Chapter 99 signifies a temporary or special classification provision. These provisions are typically enacted through trade agreements or agricultural adjustment legislation, suggesting a unique tariff or regulatory treatment outside of its standard classification in Chapter 38.

As this is a leaf node within Chapter 99, there are no further subcategories to explore. The distinction from sibling categories, which generally cover live animals, lies in its nature as a chemical compound and its placement within a chapter dedicated to temporary trade measures. Unlike the broad scope of agricultural or industrial goods found in earlier chapters, this entry points to a specific chemical substance subject to particular import regulations or duties. Its purpose, therefore, is to address specific circumstances surrounding the importation of this chemical, potentially for research, specific industrial applications, or under trade-related mandates.
