2903.79.90 - Other

This HTS category, 2903.79.90, encompasses halogenated derivatives of acyclic hydrocarbons that contain at least two different halogens, specifically excluding those explicitly listed in sibling categories. The classification hinges on the presence of multiple distinct halogen atoms (e.g., chlorine and fluorine, bromine and chlorine) attached to an acyclic hydrocarbon chain. These compounds often find use as refrigerants, propellants, or chemical intermediates, owing to their unique physical and chemical properties derived from the combination of halogens.

Distinguishing this category from its sibling, 2903.79.10 (Bromochloromethane), is crucial. While both fall under halogenated derivatives of acyclic hydrocarbons with multiple halogens, this specific subcategory is for compounds other than bromochloromethane. Therefore, any compound meeting the general criteria but not specifically identified as bromochloromethane will be classified here, provided it is not further classified under a more specific subheading.

Within this "Other" designation, further subdivisions exist to refine classification. For instance, 2903.79.90.30 specifically addresses Monochlorotetrafluoroethane (HCFC-124), a compound with a particular combination of chlorine and fluorine atoms. The remaining items not falling under these specific subheadings are then directed to 2903.79.90.70, also designated as "Other," for any residual compounds that fit the parent description but are not further enumerated.
