High-Purity Isoprene (99.5%) from Germany
Isoprene (2-methyl-1,3-butadiene) with a purity of 99.5% by weight, a chemically defined acyclic unsaturated hydrocarbon used primarily as a monomer in synthetic rubber production. It falls under HTS 2901.24.20.00 due to its high purity exceeding 95% and classification as pure isoprene per Chapter 29 notes for separate organic compounds. This excludes mixtures or impure forms covered elsewhere.

Import Tips
• Provide third-party lab analysis certificates verifying ≥95% purity by weight to avoid reclassification; declare exact purity percentage on entry documents
• Common pitfall: contamination during transport dropping below threshold—use inert atmosphere packaging
