Last updated: July 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.

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.
