HS code for Naphthylamine: 2921.45
Amine-function compounds, aromatic monoamines and their derivatives, 1-naphthylamine (alpha-naphthylamine), 2-naphthylamine (beta-naphthaylamine) and their derivatives, salts thereof.
Classification of naphthylamine under HS 2921.45
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.

Codes often confused with 2921.45
Common mistake. 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.
Top exporters and importers of HS 292145 (the code used for naphthylamine), 2025
In 2025, the largest exporter of HS 292145 (the code used for naphthylamine) in UN Comtrade data was India, with 61% of world exports; the largest importer in UN Comtrade data was India, with 37% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
