2908.19.05.00 - 2,2-Bis(4-hydroxyphenyl)-1,1,1,3,3,3-hexafluoro- propane 🖩

This classification covers halogenated derivatives of phenols and phenol-alcohols that do not fit into more specific subcategories. Specifically, this includes compounds where the phenol or phenol-alcohol structure is modified by the addition of halogen atoms, such as chlorine, bromine, or fluorine, or their salts. The defining characteristic is the presence of halogens as the primary substituents, alongside the phenolic hydroxyl group.

Within the broader category of "Derivatives containing only halogen substituents and their salts," this heading distinguishes itself from more narrowly defined entries such as 6-Chloro-m-cresol, m-Chlorophenol, Chlorothymol, 3-Hydroxy-α,α,α-trifluorotoluene, salts of pentachlorophenol, 2,4,5-Trichlorophenol and its salts, and Tetrabromobisphenol A. Those listed siblings are assigned to specific HTS codes due to their common commercial significance or distinct chemical structures, whereas this "Other" category serves as a residual entry for halogenated phenol derivatives that do not meet the specific criteria of the other subheadings.

As this is a leaf node, there are no further subcategories. Therefore, the classification for 2,2-Bis(4-hydroxyphenyl)-1,1,1,3,3,3-hexafluoro propane falls directly under this heading. The presence of fluorine atoms, a type of halogen, attached to the propane backbone, alongside the two hydroxyphenyl groups, firmly places this compound within the scope of halogenated derivatives of phenols. The critical factor for inclusion here is that the derivatization primarily involves halogens and no other significant functional groups (such as sulfur, nitrogen, or nitro groups) that would necessitate classification under different headings within Chapter 29.
