U.S. imports of organic derivatives of hydrazine or hydroxylamine (HS 292800) totaled $20.2M in April 2026, traded with 20 countries.
Importers of Organic Derivatives of Hydrazine or Hydroxylamine paid $964K in duties in April 2026 — an effective duty rate of 7.3% on $13.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Organic Derivatives of Hydrazine or Hydroxylamine imports of $20.2M in April 2026 ran 82% above the year-to-date monthly average of $11.1M.
Last updated: April 2026 dataMethyl ethyl ketoxime, phenylhydrazine, and related aromatic and non-aromatic derivatives of hydrazine and hydroxylamine serve as anti-skinning agents in paints, pharmaceutical intermediates, and chemical synthesis reagents — a functional diversity reflected in the heading's five 10-digit lines. Switzerland and Italy lead US supply, with China and India also significant sources for lower-cost technical grades. Non-aromatic derivatives intended for drug use (2928003000) are separated from general-purpose non-aromatic derivatives (2928005000), with the former potentially subject to FDA oversight depending on their role in the pharmaceutical supply chain.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Methyl ethyl ketoxime (2928001000) is singled out because of its high commercial volume as an anti-skinning agent in alkyd paints and coatings. Its separate line enables distinct statistical tracking and allows CBP to apply any applicable trade-remedy or chemical-safety measures specifically to MEKO without affecting other oxime or hydrazine derivatives.
The US schedule separates non-aromatic hydrazine/hydroxylamine derivatives used as drugs (2928003000) from those used for other purposes (2928005000). When a compound has dual-use potential, classification follows the importer's documented intended use at the time of entry. CBP may request end-use certification, and if the substance is an active pharmaceutical ingredient, FDA prior notice requirements may also apply.
