HS Code for Naphthylamine

Naphthylamine and its derivatives are classified under HS code 2921.45. This code is situated within Chapter 29 (Organic Chemicals) and heading 2921, which covers amine-function compounds. Specifically, 2921.45 is designated for 1-naphthylamine (alpha-naphthylamine), 2-naphthylamine (beta-naphthylamine), and their derivatives, including their salts. These are aromatic monoamines where the amine group is attached to a naphthalene ring. The classification is driven by the chemical identity of the substance as an aromatic amine. 1-Naphthylamine and 2-naphthylamine are critical precursors in the synthesis of azo dyes and antioxidants for rubber. The classification remains in 2921.45 even when these amines are in the form of salts, such as naphthylamine hydrochloride. Because 2-naphthylamine is a known carcinogen, its trade is strictly regulated in many jurisdictions, but the HS classification remains based on its chemical structure regardless of regulatory status. The derivatives mentioned in this subheading include substituted naphthylamines where the substitution does not introduce a functional group that would lead to classification in a later heading.

Products Included

• 1-Naphthylamine (Alpha-naphthylamine)
• 2-Naphthylamine (Beta-naphthylamine)
• Salts of naphthylamines (e.g., hydrochlorides)
• Phenyl-1-naphthylamine
• Phenyl-2-naphthylamine
• Ethyl-naphthylamine derivatives

Common Misclassification

A common misclassification occurs with HS code 2922, which covers oxygen-function amino-compounds. If the naphthylamine derivative contains an oxygen-based functional group (like a hydroxyl or ether group) in addition to the amine group, it must be classified in 2922. Another error is confusing these with heterocyclic compounds in heading 2933. Furthermore, if the naphthylamine is already converted into a finished synthetic organic dye, it belongs in heading 3204.
