2903.46.10.00 - 1,1,1,2,3,3,3-Heptafluoropropane (HFC-227ea),1,1,1,2,2,3-hexafluoropropane (HFC-236cb),1,1,1,2,3,3-hexafluoropropane (HFC-236ea) and 1,1,1,3,3,3-hexafluoropropane (HFC-236fa) 🖩

This HTS classification covers specific saturated fluorinated derivatives of acyclic hydrocarbons, primarily those containing a higher number of fluorine atoms, resulting in complex fluoropropane compounds. The listed substances, including 1,1,1,2,3,3,3-Heptafluoropropane (HFC-227ea), 1,1,1,2,2,3-hexafluoropropane (HFC-236cb), 1,1,1,2,3,3-hexafluoropropane (HFC-236ea), and 1,1,1,3,3,3-hexafluoropropane (HFC-236fa), are distinct from simpler fluorocarbons based on their molecular structure and the number of fluorine and propane units.

The distinction between this category and its siblings lies in the degree of fluorination and the resulting molecular composition. Earlier sibling categories, such as those covering trifluoromethane (HFC-23) or difluoromethane (HFC-32), deal with less complex and less fluorinated compounds. As the HTS codes progress, they encompass molecules with increasing numbers of fluorine atoms and carbon chains. This specific category is reserved for those fluoropropanes with seven or six fluorine atoms, respectively, differentiating them from the tetrafluoro-, pentafluoro-, and trifluoroethane compounds found in other sibling entries.

As a leaf node, this classification does not contain further subdivisions. Therefore, the primary classification criteria will focus on accurately identifying the chemical name and structure of the imported substance to ensure it precisely matches the description provided for HTS code 2903.46.10.00. This level of specificity is crucial for distinguishing these complex fluorinated hydrocarbons from other related chemical compounds within Chapter 29.
