Last updated: April 2026 dataFormic acid (methanoic acid), classified under a single 10-digit line (2915110000), is a widely traded industrial chemical used in leather tanning, textile processing, silage preservation, and as a descaling agent. Finland and Spain are the leading US import sources, reflecting the concentration of large-scale formic acid production capacity in Northern and Western Europe. The compound's corrosive nature requires compliance with DOT hazardous-materials transport regulations, and importers should confirm proper UN packaging and labeling before shipment.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Finland and Spain host large integrated methanol-based formic acid plants with established logistics to North America. While Chinese production capacity exists, freight costs, handling requirements for corrosive bulk liquids, and established supply relationships have kept European suppliers at the top of the US import mix.
Formic acid is classified as a corrosive hazardous material under DOT regulations (49 CFR). Shipments require proper UN packaging certification, hazard labeling, and a Safety Data Sheet. Ocean freight must comply with IMDG Code requirements, and importers should ensure the commercial invoice reflects the correct technical grade and concentration.
