2907.29.05.00 - Phenol-alcohols

This HTS category, 2907.29.05.00, specifically covers phenol-alcohols that do not fall under more specific subheadings within the Polyphenols and phenol-alcohols grouping. Phenol-alcohols are organic compounds characterized by the presence of both a hydroxyl group attached to an aromatic ring (phenol) and a hydroxyl group attached to an aliphatic carbon chain. These compounds can exhibit a range of properties depending on the structure and position of these functional groups.

To accurately classify under this heading, it's important to distinguish these general phenol-alcohols from their more specifically enumerated siblings. For instance, pyrogallic acid (2907.29.10.00), 4,4'-biphenol (2907.29.15.00), and tert-butylhydroquinone (2907.29.25.00) are all distinct polyphenols or phenol-alcohols with their own dedicated HTS codes due to their specific chemical structures and common commercial uses. If a phenol-alcohol does not match the chemical identity or specific designation of these sibling categories, it would likely be classified as "Other" under 2907.29.90.00, or if it meets the criteria for this particular subheading, under 2907.29.05.00.

As this is a leaf node, there are no further subcategories to introduce. Therefore, classification within 2907.29.05.00 relies on a careful examination of the chemical structure of the imported substance and its exclusion from more specific provisions within Chapter 29. This generally involves confirming the presence of both phenolic and alcoholic hydroxyl groups while ruling out classification under specific polyphenols like pyrogallic acid, biphenol, or tert-butylhydroquinone.
