U.S. imports of ether-alcohols, ether-phenols, peroxides & their derivatives (SITC 51617) totaled $26.2M in April 2026, traded with 30 countries.
Importers of Ether-Alcohols, Ether-Phenols, Peroxides & Their Derivatives paid $2.0M in duties in April 2026 — an effective duty rate of 10% on $19.1M in dutiable value, based on actual customs collections rather than the published tariff schedule. Ether-Alcohols, Ether-Phenols, Peroxides & Their Derivatives imports of $26.2M in April 2026 ran 16% above the year-to-date monthly average of $22.6M.
Last updated: April 2026 dataEther-alcohols such as glycol ethers (e.g., ethylene glycol monobutyl ether) are widely used as coalescing agents in waterborne coatings, cleaning formulations, and semiconductor process chemicals, while ether-phenols serve as antioxidant and surfactant precursors. Alcohol, ether, and ketone peroxides within this heading — including methyl ethyl ketone peroxide — are classified as organic peroxides and subject to strict DOT hazardous materials transport rules. The heading also captures halogenated, sulfonated, nitrated, and nitrosated derivatives, requiring precise chemical documentation for correct entry.

Alcohol, ether, and ketone peroxides are thermally unstable and can decompose exothermically, posing fire and explosion risks. DOT classifies them as Class 5.2 organic peroxides, requiring specific packaging (often temperature-controlled), labeling, and shipping documentation. Importers must ensure that the foreign shipper's packaging meets UN performance standards and that the entry documents reflect the correct hazard classification.
Semiconductor-grade glycol ethers require ultra-low metal content (parts-per-trillion levels for key metals) and strict control of particulate matter, far exceeding the purity standards acceptable for industrial coatings. Importers supplying electronics manufacturers should obtain supplier certificates of analysis that address these trace-metal and particle specifications, as standard industrial-grade product will not meet fab requirements.
