U.S. imports of sulfuric acid & oleum (HS 280700) totaled $34.2M in April 2026, traded with 20 countries.
Last updated: April 2026 dataSulfuric acid and its fuming form, oleum, are among the highest-volume industrial chemicals in global trade, serving as essential inputs for fertilizer production, petroleum refining, metal leaching, and chemical synthesis. Both products are classified under a single 10-digit line (2807000000). Canada and Mexico are the leading US suppliers, consistent with the heavy industrial integration across North American borders, with Taiwan, Spain, and Japan also contributing. DOT hazardous-materials regulations govern transport, and importers handling oleum (which contains free sulfur trioxide) face additional containment requirements beyond those for standard sulfuric acid.

Oleum (fuming sulfuric acid) contains dissolved sulfur trioxide, making it more reactive and corrosive than standard sulfuric acid. Both fall under 2807000000, but oleum requires more stringent containment and emergency-response planning under DOT hazmat rules. Buyers should specify concentration and free-SO3 content in purchase contracts.
Sulfuric acid is heavy and corrosive, making long-distance ocean freight costly and risky. Canada and Mexico benefit from overland transport proximity and integrated North American chemical and mining supply chains, particularly for acid used in copper and phosphate fertilizer production.
