2916.14.20.10 - Ethyl methacrylate

This HTS code, 2916.14.20.10, specifically classifies Ethyl methacrylate. Ethyl methacrylate is an ester of methacrylic acid and is characterized by its ethyl group attached to the carboxyl function. It is a clear, colorless liquid with a distinctive, somewhat pungent odor, and is widely used as a monomer in the production of polymers, copolymers, and resins. These polymers find applications in various industries, including coatings, adhesives, plastics, and dental materials.

Within the broader category of esters of methacrylic acid, this classification distinguishes Ethyl methacrylate from its sibling categories. Specifically, 2916.14.20.20 covers Methyl methacrylate, which differs by the presence of a methyl group instead of an ethyl group. The "Other" category at this level, 2916.14.20.50, is reserved for esters of methacrylic acid not otherwise specified, meaning it would include compounds with different alkyl or aryl groups attached to the ester functionality.

As this classification is a leaf node, there are no further subcategories to introduce. The focus for classification under 2916.14.20.10 is therefore on the definitive identification of the substance as Ethyl methacrylate, ensuring it is not misclassified as another methacrylate ester or a related but distinct chemical compound. Classification relies on the chemical identity of the ester group.
