Importers of Butanols (Other), Including Isobutyl and Tert-Butyl Alcohol paid $750K in duties in July 2026 — an effective duty rate of 10% on $7.4M in dutiable value, based on actual customs collections rather than the published tariff schedule. Butanols (Other), Including Isobutyl and Tert-Butyl Alcohol imports of $7.4M in July 2026 ran 227% above the year-to-date monthly average of $2.3M.
Last updated: July 2026 dataThe 'butanols, NESOI' heading captures butanol isomers not covered by the n-butyl alcohol heading, most notably isobutyl alcohol (2905145010) and tert-butyl alcohol below 99% purity (2905141000), along with residual butanol types (2905145050). Tert-butyl alcohol is a key intermediate in MTBE production and as a pharmaceutical solvent, while isobutyl alcohol serves coatings and flavoring applications. Netherlands and the United Kingdom are the leading US suppliers, reflecting Western Europe's specialty alcohol manufacturing base.

Line 2905141000 specifically covers tert-butyl alcohol with purity less than 99% by weight. Higher-purity tert-butyl alcohol may be classified differently depending on its form and intended use. Importers should verify purity on the certificate of analysis before filing, as the purity threshold directly determines the applicable 10-digit line.
Both are C4 primary alcohols, but isobutyl alcohol (2-methylpropan-1-ol) has a branched structure that gives it different solvent properties — lower toxicity profile and higher boiling point relative to n-butanol — making it preferred in certain coatings and flavoring applications. For HTS purposes, isobutyl alcohol falls under 2905.14 (line 2905145010), not the dedicated 2905.13 heading reserved for n-butyl alcohol.
