U.S. imports of toluene (high purity) (HS 290230) totaled $6.0M in May 2026, traded with 8 countries.
Importers of Toluene (High Purity) paid $452K in duties in May 2026 — an effective duty rate of 10% on $4.5M in dutiable value, based on actual customs collections rather than the published tariff schedule. Toluene (High Purity) imports of $6.0M in May 2026 ran 40% below the year-to-date monthly average of $10.1M.
Last updated: May 2026 dataToluene at 95% or greater purity by weight, classified under 2902300000, functions both as a high-octane gasoline blending component and as a chemical intermediate for toluene diisocyanate (TDI), benzene (via hydrodealkylation), and benzoic acid. Taiwan leads US imports under this heading, followed by South Korea and Canada — a supplier mix that reflects the concentration of aromatic petrochemical capacity in East Asia. Like benzene, toluene is a DOT hazardous material requiring proper shipping documentation, and its dual role as a fuel component and chemical feedstock can affect how it is valued and documented at entry.

Toluene meeting the 95% purity threshold is properly classified in Chapter 29 (heading 2902300000) as a defined chemical compound, not in Chapter 27. However, lower-purity toluene-rich streams — such as those derived directly from reformate without further purification — may fall under Chapter 27. The purity level, confirmed by a CoA, is the decisive classification factor, and importers should retain that documentation in their records.
When toluene is imported for fuel-blending purposes, it may be subject to EPA fuel additive regulations and excise tax considerations in addition to standard customs entry requirements. When imported as a chemical feedstock, TSCA inventory status is the primary regulatory concern. Importers should clearly state the intended end use in commercial documentation, as this can affect both the applicable regulatory pathway and the valuation methodology used by CBP.
