HS Code 2921.45 – Amine-function compounds; aromatic monoamines and their derivatives; 1-naphthylamine (alpha-naphthylamine), 2-naphthylamine (beta-naphthaylamine) and their derivatives; salts thereof

HS code 2921.45 is the 6-digit subheading for amine-function compounds, aromatic monoamines and their derivatives, 1-naphthylamine (alpha-naphthylamine), 2-naphthylamine (beta-naphthaylamine) and their derivatives, salts thereof. It is used for 1-Naphthylamine, 1-Naphthylamine-4-sulfonic acid, N-phenyl-1-naphthylamine, 1-Naphthylamine hydrochloride and N-methyl-1-naphthylamine.

What HS 2921.45 covers

This HS code covers 1-naphthylamine (alpha-naphthylamine), 2-naphthylamine (beta-naphthylamine), and their derivatives, including salts. These are aromatic amines derived from naphthalene, serving as important intermediates in the synthesis of dyes, pigments, and rubber chemicals. Due to significant health concerns, particularly the carcinogenicity of 2-naphthylamine, its use is highly restricted or banned in many regions. Consequently, legitimate international trade primarily focuses on 1-naphthylamine and its derivatives for specific industrial applications where safer alternatives are not viable or for research purposes. Importers are typically specialty chemical manufacturers, while exporters are often fine chemical producers. Strict regulatory compliance and safety protocols are paramount in the trade of these compounds.

Codes often confused with 2921.45

Common mistake. Can be confused with other aromatic monoamines (292149) or even other naphthalene derivatives (e.g., 2903.99 for halogenated, 2907.29 for phenols) if the amine function is overlooked.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
