Isoprene (2-Methyl-1,3-Butadiene) Petroleum Grade from Germany
Petroleum-derived isoprene (C5H8) is a conjugated diene unsaturated hydrocarbon extracted from C5 fractions of petroleum cracking. HTS 2901.29.10 covers this as an other unsaturated acyclic hydrocarbon from petroleum, not the first four alkenes. Primary use in synthetic rubber (IR, SBR) production.

Import Tips
• Provide refinery C5 stream analysis confirming isoprene content and petroleum origin
• Polymerization inhibitor certificates required; uninhibited isoprene poses runaway reaction risk
• Classify as UN 1218; ensure refrigerated transport below 20°C to prevent spontaneous polymerization
