U.S. imports of epoxides, epoxyalcohols, epoxyphenols & epoxyethers (nes) (SITC 51615) totaled $8.7M in April 2026, traded with 21 countries.
Importers of Epoxides, Epoxyalcohols, Epoxyphenols & Epoxyethers (NES) paid $863K in duties in April 2026 — an effective duty rate of 19% on $4.5M in dutiable value, based on actual customs collections rather than the published tariff schedule. Epoxides, Epoxyalcohols, Epoxyphenols & Epoxyethers (NES) imports of $8.7M in April 2026 ran 32% below the year-to-date monthly average of $12.8M.
Last updated: April 2026 dataBeyond the major commodity epoxides covered in dedicated headings, this residual category captures three-membered ring epoxy compounds — including epoxyalcohols, epoxyphenols, and epoxyethers — along with their halogenated, sulfonated, nitrated, or nitrosated derivatives not elsewhere specified. These specialty epoxides serve as reactive diluents, chiral building blocks, and crosslinking agents in coatings, adhesives, and pharmaceutical synthesis. Correct classification requires confirming that the compound is not more specifically provided for under a named epoxide heading, making chemical identity documentation essential.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Classification in an NES heading requires ruling out all more-specific provisions. Importers should provide the full chemical name, CAS registry number, and structural formula to their customs broker, who can cross-reference against named epoxide headings (such as ethylene oxide or propylene oxide) and any applicable CBP binding rulings before filing the entry.
Enantiopure epoxides — such as glycidol derivatives and styrene oxide isomers — are valued as chiral synthons for active pharmaceutical ingredient synthesis. Their import may trigger FDA review if they are intended as drug intermediates, and suppliers must typically provide documentation of stereochemical purity alongside standard certificates of analysis.
