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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived directly from petroleum distillation without purification
Crude cyclic hydrocarbons from petroleum gases fall under Chapter 27, but purified DCPD is classified here per Chapter 29 notes.
If considered a saturated cyclane rather than bicyclic cyclene
Saturated cyclic hydrocarbons (cyclanes) are in 2901, but DCPD's double bonds qualify it as a cyclene in 2902.
If imported as a mixture with solvents or stabilizers exceeding Chapter 29 allowances
Mixtures not qualifying as chemically defined compounds per Chapter 29 note (a) fall under prepared chemical mixtures in 3824.

Import Tips & Compliance
• Provide chemical purity certificates and CAS number (77-73-6) documentation to verify classification as a separate chemically defined organic compound
• Ensure proper Hazard Communication labeling as it is flammable and requires UN-approved packaging for transport
• Avoid misclassification by confirming it's not mixed with impurities exceeding chapter note tolerances
