Last updated: July 2026 dataSulfuric acid — the world's most widely produced industrial chemical — and its fuming form, oleum, enter the US under a single tariff line (2807000000), reflecting their commodity status in fertilizer production, metal processing, and petroleum refining. Canada and Mexico are the dominant suppliers, a pattern driven by integrated North American industrial infrastructure and the economics of transporting a dense, corrosive bulk liquid over short distances. Importers should note that both products are regulated as hazardous materials under DOT and are subject to EPA TSCA reporting, with oleum carrying additional handling requirements due to its free sulfur trioxide content.

Both sulfuric acid and oleum (fuming sulfuric acid, which contains dissolved sulfur trioxide) are classified under the same HTS line 2807000000. For handling and transport, however, oleum is treated as a more hazardous material due to its free SO₃ content, requiring specialized tank cars or ISO containers and stricter emergency-response planning under DOT and EPA regulations.
Sulfuric acid is a high-density, corrosive bulk commodity where freight costs are a major factor in sourcing decisions. Proximity to US industrial centers — particularly copper smelters and fertilizer plants — makes Canadian and Mexican producers the most cost-competitive suppliers, and cross-border infrastructure supports efficient bulk liquid transport.
