Products classified under HTS 2933.71.00.00
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.
Caprolactam Powder 99.5% Pure
High-purity ε-Caprolactam powder used exclusively as nylon 6 monomer feedstock. Falls under HTS 2933.71.00.00 as a separate chemically defined heterocyclic lactam per Chapter 29 note (a). Industrial grade for polymer manufacturing.
Industrial ε-Caprolactam Pellets
Pelletized ε-Caprolactam for convenient handling in nylon polymerization reactors. Specifically classified under 2933.71.00.00 as the heterocyclic lactam 6-hexanelactam. Meets Chapter 29 requirements for separate chemically defined compounds.
BASF Caprolactam UltraPure Grade
BASF-brand ultra-high purity ε-Caprolactam (>99.9%) for premium nylon 6 fiber production. Classified as 6-Hexanelactam under HTS 2933.71.00.00 due to its pure heterocyclic lactam chemical identity. Used in high-performance engineering plastics.
Toray Caprolactam for Nylon Film
Toray-grade ε-Caprolactam optimized for nylon 6 film extrusion applications. Falls squarely under HTS 2933.71.00.00 as the defined heterocyclic lactam compound. Chemical structure dictates classification regardless of intended polymer end-use.
Caprolactam with Stabilizer Additive
ε-Caprolactam containing minimal phosphoric acid stabilizer for transport stability. Remains classified under HTS 2933.71.00.00 per Chapter 29 note (f) allowing stabilizers necessary for preservation. Active content >99% lactam.
