Last updated: August 2026 dataUrea is the world's most widely traded nitrogen fertilizer and a critical agricultural input, but the US tariff schedule also carves out a distinct line for Diesel Exhaust Fluid (DEF) — aqueous urea meeting ISO 22241 — used in selective catalytic reduction systems on diesel engines. Solid urea (3102100010) and DEF (3102100030) face different end-use markets and supply chains despite sharing the same HS6 heading. Russia and Qatar are the leading suppliers, reflecting the competitive advantage of natural-gas-rich exporters in urea synthesis; importers should monitor geopolitical developments that can rapidly tighten supply from these concentrated sources.

DEF that meets ISO 22241 specifications is classified under 10-digit line 3102100030, while solid granular or prilled urea used as fertilizer falls under 3102100010. The distinction matters because DEF is subject to different end-use documentation expectations and may be sourced from different suppliers than bulk agricultural urea. Importers should confirm the ISO 22241 specification on the commercial invoice when claiming the DEF line.
Russia and Qatar together account for a large share of US urea imports, creating concentration risk tied to export policy decisions, sanctions exposure in the case of Russia, and LNG-linked feedstock economics in Qatar. Agricultural buyers in particular should consider forward contracting and diversification toward Canadian or other suppliers to buffer against sudden supply disruptions during planting season.
