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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing an oxygen function like the epoxidized derivative
Oxygenated derivatives shift to later headings per Chapter 29 classification rule (last in numerical order).
If already polymerized into poly(dicyclopentadiene)
Polymerized forms are plastics of Chapter 39, not the monomer hydrocarbon.
If for chemical kits containing DCPD with other reagents for lab use
Sets of chemicals for specific analysis move to 3824 per Section VI notes.

Import Tips & Compliance
• Submit isomer specification sheets to distinguish endo from exo forms and confirm statistical reporting suffix
• Comply with TSCA import certification for new chemical substances if purity exceeds prior import records
• Use stainless steel drums to prevent polymerization during shipping, common pitfall causing blocked shipments

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.
High Purity Dicyclopentadiene 99%+
High purity DCPD (99%+) meets pharmaceutical intermediate standards and is classified under HTS 2902.19.00.10 as a separate chemically defined cyclic hydrocarbon. Its distillation removes impurities for use in fine chemical synthesis.
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).
