Toluene

Yes. Toluene destined for solvent applications is subject to EPA VOC regulations and may face state-level restrictions under air quality programs such as California's CARB rules. Fuel-grade toluene used as a gasoline blendstock must meet EPA Tier 3 fuel sulfur and other specifications. Importers should document intended end use clearly, as this affects both regulatory compliance and applicable standards.

Toluene is a direct feedstock for toluene diisocyanate (TDI), a key raw material in flexible polyurethane foam for furniture and automotive seating. Demand from TDI producers creates a distinct industrial buyer segment separate from solvent and fuel markets, and supply disruptions in toluene can cascade into TDI and downstream foam pricing. Importers serving chemical producers should monitor integrated petrochemical plant operating rates as a demand signal.
