HS Code 2921.42 – Amine-function-compounds; aromatic monoamines and their derivatives, aniline derivatives and their salts

HS code 2921.42 is the 6-digit subheading for amine-function-compounds, aromatic monoamines and their derivatives, aniline derivatives and their salts. It is used for N-ethylaniline, N-isopropylaniline, 4-chloroaniline, 2-nitroaniline and 4-aminoacetophenone.

What HS 2921.42 covers

This category covers aniline derivatives and their salts, encompassing a broad range of compounds structurally related to aniline but with additional substituents. These derivatives are vital intermediates in the synthesis of specialty chemicals, including pharmaceuticals, agrochemicals, dyes, and advanced polymer additives. They often possess enhanced or modified properties compared to basic aniline, making them suitable for more specific and high-value applications. Trade involves chemical manufacturers supplying to specialized industries that require these tailored intermediates. Importers are typically companies engaged in fine chemical synthesis, while exporters are often global chemical producers with diverse product portfolios. Purity, specific isomer, and regulatory compliance are critical trade considerations.

Codes often confused with 2921.42

Common mistake. Can be confused with pure aniline (292141) or other aromatic monoamines (292149) if the specific 'derivative' aspect of aniline is not clearly identified, leading to incorrect classification.

Top exporters and importers of HS code 292142, 2025

In 2025, the largest exporter of HS code 292142 in UN Comtrade data was India, with 61% of world exports; the largest importer in UN Comtrade data was the United Arab Emirates, with about 29% of world imports. Russia did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 46% of its exports here ($4.3M, CEPII BACI), so it may also belong among the top exporters.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
