Import Tips & Compliance
β’ Quantify anti-caking agent <2% w/w with particle size analysis to meet 'added for safety' criteria
β’ Include flowability test data proving necessity for transport vs retail packaging
β’ Avoid Chapter 38 mixture classification by maintaining lactam as predominant identified compound

Caprolactam
Caprolactam is a cyclic amide (lactam) with a six-membered ring containing a nitrogen hetero-atom, used primarily as a monomer in the production of nylon 6 polymer. It falls under HTS 2933.79.85.00 as a lactam that is neither specifically named in prior subheadings nor a beta-lactam antibiotic structure. This chemically defined heterocyclic compound with nitrogen hetero-atom only meets Chapter 29 requirements for classification.
2-Pyrrolidone (2-Pyrrolidinone)
2-Pyrrolidone is a five-membered lactam ring compound used as a high-boiling solvent in pharmaceuticals, electronics, and polymer manufacturing. Classified under HTS 2933.79.85.00 as an other lactam with nitrogen hetero-atom only, not specifically enumerated elsewhere. Its cyclic amide structure distinguishes it from acyclic amides.
Epsilon-Caprolactam Technical Grade
Technical grade epsilon-caprolactam contains 95-99% purity with stabilizers, used in industrial nylon production. Falls under HTS 2933.79.85.00 as other lactams per chapter notes allowing stabilizers for preservation/transport. Remains classified as chemically defined compound despite minor impurities.
N-Methyl-2-Pyrrolidone Stabilized
N-Methyl-2-pyrrolidone (NMP) is a methylated lactam used as solvent in battery production and paint strippers, here with anti-oxidant stabilizer. Classified HTS 2933.79.85.00 as other lactams (distinct from unsubstituted 2933.79.29). Stabilizer permitted per chapter note (f) for preservation.
Piperidin-2-One
Piperidin-2-one (Ξ΄-valerolactam) is a six-membered lactam ring used in organic synthesis and polymer chemistry. Classified under HTS 2933.79.85.00 as other lactams with nitrogen hetero-atom only. Distinguish from piperidine bases by amide functionality.
Valerolactam (5-Methyl-2-Pyrrolidone)
Valerolactam is a substituted five-membered lactam used in polymer synthesis and as pharmaceutical intermediate. HTS 2933.79.85.00 covers this alkyl-substituted lactam not specifically named in prior subheadings. Meets nitrogen-heteroatom only heterocyclic criteria.
