Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing organo-metallic impurities directly linked to carbon
Organo-inorganic compounds with metal-carbon bonds fall under 2931 per Chapter 29 note.
If statistically reported as 'other' cyclenes not specifically DCPD
Same heading but different statistical suffix; DCPD has dedicated 10-digit reporting.
If hydrogenated to dicyclopentane (saturated derivative)
Fully saturated derivatives become cyclanes in 2901 or related headings.

Import Tips & Compliance
• Include GC-MS analysis certificates proving ≥99% purity to avoid reclassification as technical grade
• Register under TSCA Premanufacture Notification if first import exceeds 10,000 lbs annually
• Monitor for inhibitor addition; stabilized versions may require verification they don't render product use-specific

Dicyclopentadiene (DCPD)
Dicyclopentadiene is a bicyclic cyclic hydrocarbon formed by the Diels-Alder reaction of two cyclopentadiene molecules, classified under HTS 2902.19.00.10 as a cyclene other than cyclanes or cycloterpenes. It appears as a colorless liquid with a camphor-like odor and is a key intermediate in polymer production.
Endo-Dicyclopentadiene 95% Technical Grade
Technical grade endo-DCPD at 95% purity is a primary isomer of dicyclopentadiene used in synthetic resin manufacturing, falling under HTS 2902.19.00.10 as a chemically defined cyclic hydrocarbon. The endo form is preferred for its reactivity in polymerization reactions.
Distilled Dicyclopentadiene from Byproduct Streams
DCPD recovered and purified from C5 petroleum byproduct streams via distillation, classified as a chemically defined cyclic hydrocarbon under HTS 2902.19.00.10. This industrial-grade material serves as the primary feedstock for hydrocarbon resins.
Dicyclopentadiene Inhibited with BHT
DCPD stabilized with butylated hydroxytoluene (BHT) prevents premature polymerization during storage and transport, classified under HTS 2902.19.00.10 per Chapter 29 note (f) for added stabilizers. The stabilizer level is minimal and necessary for preservation.
Exo-Isomer Enriched Dicyclopentadiene
DCPD enriched in the exo-isomer (typically 60-70%) offers different reactivity profiles for specialty polymer applications, classified under HTS 2902.19.00.10 as the specific cyclic hydrocarbon. Isomer mixtures remain chemically defined per Chapter 29 note (b).
