2933.79.30.00/N-Vinyl-2-Pyrrolidone Monomer (NVP)/Japan

N-Vinyl-2-Pyrrolidone Monomer (NVP) from Japan

N-Vinyl-2-pyrrolidone (NVP) is a heterocyclic lactam monomer with a vinyl group attached to the nitrogen hetero-atom of the 2-pyrrolidone ring. It is used primarily in the production of polyvinylpyrrolidone (PVP) polymers for pharmaceuticals, cosmetics, and adhesives. This pure chemical compound falls under HTS 2933.79.30.00 as a specific 'other lactam' due to its defined heterocyclic structure.

Import Tips

• Provide detailed chemical analysis certificates confirming purity as NVP monomer to avoid reclassification as a polymer under Chapter 39

• Ensure SDS (Safety Data Sheets) and proper UN shipping labels for flammable liquid handling during customs clearance

• Verify inhibitor content (e.g

• hydroquinone) in documentation, as polymerization during transit can lead to shipment rejection
