HS Code for Caprolactam

Caprolactam is classified under HS code 2933.71. This classification is found within Chapter 29, which covers organic chemicals. Specifically, Heading 2933 is designated for heterocyclic compounds with nitrogen hetero-atom(s) only. Caprolactam is a cyclic amide, also known as a lactam. The Harmonized System provides a specific six-digit subheading (2933.71) for 6-hexanelactam, which is the chemical name for epsilon-caprolactam. This classification is based on the molecular structure of the compound, which consists of a seven-membered ring containing six carbon atoms and one nitrogen atom. Caprolactam is a vital industrial chemical, primarily used as a monomer in the ring-opening polymerization process to produce Nylon 6 (polyamide 6). Because it is a clearly defined chemical individual, it must be classified in Chapter 29 rather than with the polymers it produces.

Products Included

• Epsilon-caprolactam (pure form)
• 6-hexanelactam
• Caprolactam flakes or molten liquid
• Industrial grade caprolactam for nylon production
• Caprolactam used in the manufacture of synthetic resins

Common Misclassification

A common error is classifying caprolactam under HS code 3908.10, which is the code for Polyamide-6 in primary forms. While caprolactam is the precursor to Nylon 6, the monomer itself is a chemical compound and must remain in Chapter 29. Another potential error is using HS code 2933.79, which is the 'other' category for lactams. Since caprolactam is specifically named in subheading 2933.71, the 'other' category is incorrect. Importers must also distinguish it from other nitrogen-function compounds in Heading 2924 (acyclic amides), as the cyclic nature of caprolactam mandates its placement in Heading 2933.

FAQ

What is the HS code for Caprolactam?

The specific HS code for Caprolactam (6-hexanelactam) is 2933.71.

Is Caprolactam classified as a plastic or a chemical?

It is classified as an organic chemical in Chapter 29, not as a plastic, because it is a monomer/precursor and not a polymer.
