Overview
This HTS category, specifically 2933.79.30.00, covers N-Vinyl-2-pyrrolidone in its monomeric form. This is a specific organic chemical compound characterized by a vinyl group attached to the nitrogen atom of a 2-pyrrolidone ring. Its primary industrial application is as a monomer for the production of polyvinylpyrrolidone (PVP) and its copolymers, which are widely used in pharmaceuticals, cosmetics, adhesives, and as clarifying agents in beverages.
This classification distinguishes N-Vinyl-2-pyrrolidone from its sibling categories. For instance, 2933.79.20.00 specifically includes N-Methyl-2-pyrrolidone and 2-Pyrrolidone, which are structurally similar but lack the vinyl group, thus possessing different chemical properties and applications. Similarly, 2933.79.40.00 covers 12-Aminododecanoic acid lactam, a different lactam with a longer aliphatic chain. The "Other" category (2933.79.85.00) is reserved for lactams not otherwise specified in this group.
As this is a leaf node in the HTS classification system, there are no further subcategories for 2933.79.30.00. The classification is precise, focusing on the unique chemical structure of N-Vinyl-2-pyrrolidone monomer. Therefore, accurate classification hinges on confirming the identity and form of the imported chemical substance, ensuring it aligns with the defined characteristics of N-Vinyl-2-pyrrolidone monomer and not other related lactams.
