2902.19.00.10 - Dicyclopentadiene

This HTS classification covers dicyclopentadiene (DCPD), a bicyclic hydrocarbon derived from cyclopentadiene. DCPD is a colorless to yellowish liquid with a distinctive odor. It is primarily used as a monomer or comonomer in the production of various resins, including unsaturated polyester resins, hydrocarbon resins, and high-performance polymers. Its reactive nature makes it valuable in the synthesis of specialty chemicals and as a cross-linking agent.

Within the broader category of "Cyclanes, cyclenes and cycloterpenes: Other," dicyclopentadiene is specifically identified by its unique chemical structure. Its sibling category, 2902.19.00.50, also designated as "Other," likely encompasses other cyclic hydrocarbons that do not fit into more specific subheadings within this chapter but are not dicyclopentadiene itself. The distinction lies in the precise chemical identity and common industrial applications of dicyclopentadiene.

As this is a leaf node in the HTS classification system, there are no further subdivisions. Therefore, the classification of dicyclopentadiene is definitive at this level. Classification decisions under this code should be based on whether the imported substance is chemically identified as dicyclopentadiene, considering its common forms and purity levels as relevant for its intended industrial use.
