Industrial Isoprene from C5 Raffinate
Extracted isoprene from C5 petroleum cracker stream, 95-97% purity for polyisoprene rubber production. Qualifies as chemically defined organic compound per Chapter 29(a) despite raffinate origin. 'Other' form under HTS 2901.24.50.00 excludes high-purity monomer specs.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not extracted but remains in C5 cracker stream
Unseparated petroleum distillates containing isoprene classified as petroleum gases/products.
If polymerized on import to latex
Polymerized isoprene products become synthetic rubber latices under Chapter 40.
If pharmaceutical grade ≥99.5% purity
Higher purity specifications fall under specific 'pharmaceutical grade' statistical breakout.

Import Tips & Compliance
• Submit distillation specs showing isoprene predominance over other C5s (pipylene, cyclopentadiene) for Chapter 29 eligibility
• Large volume imports (>20MT) require TSCA Premanufacture Notice if not on inventory; verify PMN status

99% Pure Isoprene Monomer
High-purity isoprene (2-methyl-1,3-butadiene) used as a key monomer in synthetic rubber production. This acyclic unsaturated hydrocarbon falls under HTS 2901.24.50.00 as 'other' isoprene not specified elsewhere in the isoprene subheading. It meets Chapter 29 requirements for separate chemically defined organic compounds.
Research-Grade Isoprene (98% purity)
Laboratory reagent grade isoprene packaged in 100g glass ampoules for chemical synthesis research. Meets Chapter 29(a) definition of separate chemically defined compound with controlled impurities. Falls specifically under 2901.24.50.00 as 'other' isoprene form.
Isoprene with p-Menthadiene Impurities
Commercial isoprene containing controlled p-menthadiene impurities from thermal dimerization limits. Still classified as principal isoprene compound per Chapter 29 classification rules. 'Other' category accommodates typical commercial impurity profiles.
Stabilized Isoprene for Synthetic Rubber
Polymerization-grade isoprene containing TBHP stabilizer to prevent premature polymerization during storage and transport. Classified under HTS 2901.24.50.00 per Chapter 29 note (f) allowing stabilizers necessary for preservation. Remains chemically defined isoprene despite added stabilizer.
