U.S. imports of aniline derivatives and their salts (HS 292142) totaled $22.4M in April 2026, traded with 8 countries.
Importers of Aniline Derivatives and Their Salts paid $850K in duties in April 2026 — an effective duty rate of 2.9% on $29.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Aniline Derivatives and Their Salts imports of $22.4M in April 2026 ran 53% above the year-to-date monthly average of $14.6M.
Last updated: April 2026 dataAniline derivatives span a commercially diverse range — from N,N-dimethylaniline and N,N-diethylaniline used as solvent and intermediate chemicals, to sulfanilic acid and orthanilic acid serving as dye and pharmaceutical intermediates, to fast color bases used directly in textile dyeing. India and China together dominate US supply of this heading, reflecting the concentration of fine chemical and dye-intermediate manufacturing in South and East Asia. The US schedule enumerates nine distinct tariff lines under 292142, including a dedicated line for fast color bases (2921425500) and a catch-all for derivatives not elsewhere specified (2921429000), so precise product identification is essential at entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Fast color bases are specific aniline derivatives designed to couple with diazonium salts on fiber to produce azo dyes in situ during textile dyeing. Their classification under 2921425500 depends on the product's intended function and chemical identity; a technical data sheet confirming the coupling mechanism and end use supports this classification over the NESOI line.
Several aniline derivative tariff lines under 292142 may be subject to Section 301 tariffs on Chinese-origin goods. Importers should verify the current Section 301 list status for the specific 10-digit HTS code at the time of entry, as product-level exclusions and list modifications occur periodically.
