2916.14.20 - Other

This HTS category, 2916.14.20, specifically pertains to esters of methacrylic acid that do not fall under the more specific classification of "Dicyclopentenyloxyethyl methacrylate" (2916.14.10.00). These are organic compounds derived from methacrylic acid and an alcohol, characterized by their unsaturated acyclic structure and ester functional group. They are commonly used as monomers in the production of polymers and resins, such as polymethyl methacrylate (acrylic glass) and other acrylic-based materials.

The distinction from the sibling category, 2916.14.10.00, lies in the specific chemical structure of the ester. While both are esters of methacrylic acid, 2916.14.10.00 is designated for a particular compound with a dicyclopentenyloxyethyl group attached. Therefore, 2916.14.20 encompasses all other esters formed by the reaction of methacrylic acid with various alcohols, excluding the specifically enumerated dicyclopentenyloxyethyl methacrylate.

To further refine classification within this group, subcategories exist. 2916.14.20.10 covers ethyl methacrylate, and 2916.14.20.20 identifies methyl methacrylate, both highly significant industrial chemicals. The remaining "Other" esters of methacrylic acid are classified under 2916.14.20.50, providing a catch-all for less common or specifically designated variants not otherwise enumerated.
