Polymerization-Grade Butadiene (PG Butadiene) from China
High-purity buta-1,3-diene (>99.7%) specifically refined for synthetic rubber polymerization, falling under HTS 2901.24.10.00 as a pure acyclic unsaturated hydrocarbon. Its conjugated diene structure makes it ideal for producing styrene-butadiene rubber (SBR).

Import Tips
• Provide GC-MS analysis confirming <10 ppm moisture and C4 impurities to maintain pure compound status
• Use refrigerated tankers maintaining -4°C to prevent polymerization during ocean transit
• Declare as UN1010; obtain advance CBP approval for bulk chemical imports exceeding 1000 kg
