ε-Caprolactam Flakes
Pure ε-Caprolactam in flake form, a cyclic amide classified as a lactam under HTS 2933.71.00.00 due to its six-membered heterocyclic ring containing a single nitrogen hetero-atom. Primarily used as the monomer for producing nylon 6 polymers in the textile and plastics industries.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If acyclic amide form or open-chain precursor
Acyclic carboxamides fall under heading 2924; caprolactam's cyclic lactam structure specifically directs to 2933
If pre-polymerized into low molecular weight nylon 6
Polymerized caprolactam becomes synthetic polymer under Chapter 39, not the pure heterocyclic monomer of Chapter 29
If supplied as mixture with stabilizers exceeding Chapter 29 allowances
Additives rendering it suitable for specific use move it from pure compound to chemical preparations in 3824
