3827.12.00.00 - Containing hydrobromofluorocarbons (HBFCs)

This HTS category, 3827.12.00.00, specifically addresses mixtures containing hydrobromofluorocarbons (HBFCs). These are chemical substances that have been regulated due to their ozone-depleting potential. The classification applies to products where HBFCs are a constituent component, regardless of other halogenated derivatives that might also be present, as long as HBFCs are the defining characteristic for classification within this subheading.

It is crucial to distinguish this category from its siblings. HTS 3827.11.00.00 covers mixtures primarily defined by the presence of chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs), or hydrofluorocarbons (HFCs). HTS 3827.13.00.00 applies to mixtures containing carbon tetrachloride, while HTS 3827.14.00.00 is for those containing 1,1,1-trichloroethane. Therefore, the presence of HBFCs as a primary or significant component differentiates goods classified under 3827.12.00.00.

As a leaf node, this category does not have further subdivisions. Classification under 3827.12.00.00 is therefore determined by the definitive presence of HBFCs within a mixture that falls under the broader scope of Chapter 38. Examples could include refrigerants, fire extinguishing agents, or blowing agents that contain HBFCs as a key ingredient, provided they are not specifically classified elsewhere. The key is to identify HBFCs as the governing component for classification at this detailed level.
