Products classified under Tariff item 2933.71.00.10
BASF Caprolactam UltraPure Grade
Ultra-high purity ε-Caprolactam (6-hexanelactam) exceeding 99.9% purity, used as a premium monomer for nylon 6 fiber production. Its separate chemically defined heterocyclic lactam structure falls squarely under tariff item 2933.71.00, as confirmed by Chapter 29 Note 1(a). The product's purity level does not alter its classification.
2933.71.00ε-Caprolactam Flakes
Pure ε-Caprolactam in flake form, a cyclic amide classified as a lactam under tariff item 2933.71.00 due to its six-membered heterocyclic ring with a single nitrogen hetero-atom. The physical form (flakes) does not affect classification, as Chapter 29 covers the chemical compound regardless of presentation. Primarily used as a monomer for nylon 6 production.
2933.71.00Caprolactam Powder 99.5% Pure
Industrial-grade ε-Caprolactam powder at 99.5% purity, used exclusively as a nylon 6 monomer feedstock. As a separate chemically defined organic compound with a nitrogen hetero-atom ring, it is classified under tariff item 2933.71.00 per Chapter 29 Note 1(a). The powder form does not affect classification.
2933.71.00Caprolactam with Stabilizer Additive
ε-Caprolactam containing a minimal phosphoric acid stabilizer added for transport stability, with active content exceeding 99%. Chapter 29 Note 1(f) permits stabilizers necessary for preservation or transport, so the product remains classified under tariff item 2933.71.00. The stabilizer does not render the product suitable for a specific use.
2933.71.00Industrial ε-Caprolactam Pellets
Pelletized ε-Caprolactam designed for convenient handling in nylon polymerization reactors. The pellet form is a physical presentation of the same chemically defined heterocyclic lactam, 6-hexanelactam, and is classified under tariff item 2933.71.00. Chapter 29 Note 1(a) applies to the compound regardless of its physical shape.
2933.71.00Toray Caprolactam for Nylon Film
Toray-grade ε-Caprolactam optimized for nylon 6 film extrusion applications. Despite its intended use, the product's chemical structure as 6-hexanelactam dictates classification under tariff item 2933.71.00, as Chapter 29 classifies based on chemical identity rather than end-use. The product meets the definition of a separate chemically defined compound.
