2902.19.00 - Other

This HTS category, 2902.19.00, encompasses cyclic hydrocarbons that are cyclanes, cyclenes, or cycloterpenes, but are not specifically classified under a more defined subheading. It serves as a residual category for these types of unsaturated or saturated cyclic hydrocarbons when they do not fit into more granular classifications within the broader group of cyclanes, cyclenes, and cycloterpenes.

This subheading distinguishes itself from its sibling, 2902.11.00, which specifically covers cyclohexane. Therefore, any cyclic hydrocarbon falling under the cyclane, cyclene, or cycloterpene definition, but not being cyclohexane itself, would generally fall into this "Other" classification.

The subcategories within 2902.19.00 are further refined to provide more specific classification. 2902.19.00.10 pertains to Dicyclopentadiene, a specific and commonly traded cyclic hydrocarbon. The remaining products within this broader category are then placed under 2902.19.00.50, which is also designated as "Other," indicating a further residual classification for any other compounds that meet the general description of cyclanes, cyclenes, or cycloterpenes but are not dicyclopentadiene.
