2916.14 - Esters of methacrylic acid:

This HTS category, 2916.14, specifically encompasses esters derived from methacrylic acid. These compounds are organic chemicals characterized by the presence of the methacrylic acid functional group esterified with various alcohols. They are distinct from acrylic acid esters (2916.12), which are derived from acrylic acid, and from methacrylic acid itself and its salts (2916.13.00.00). The focus here is on the ester derivatives, which often serve as monomers or intermediates in the production of polymers and resins.

Within this category, the subcategories differentiate based on the specific nature or scope of the methacrylic acid ester. 2916.14.10.00 addresses a particular ester, Dicyclopentenyloxyethyl methacrylate, likely due to its specific applications or chemical structure. The broader "Other" subcategory (2916.14.20) is intended for all other methacrylic acid esters not otherwise specified, allowing for comprehensive classification of a wide range of chemical compounds falling under this heading.
