2914.39 - Other:

This HTS category, 2914.39, encompasses aromatic ketones that possess only oxygen functionality and do not fit into more specific tariff lines within the same group. These compounds are characterized by a carbonyl group (C=O) directly attached to an aromatic ring, with no other oxygen-containing functional groups such as hydroxyl (-OH), ether (-O-), or carboxylic acid (-COOH) present. The scope is broad, covering various aromatic ketones not explicitly listed elsewhere.

Distinguishing this category from its sibling, 2914.31.00.00, is crucial. The sibling category specifically identifies Phenylacetone (Phenylpropan-2-one), a single, well-defined aromatic ketone. Therefore, 2914.39 applies to all other aromatic ketones that meet the general criteria but are not Phenylacetone.

To further refine classification, subcategories exist. 2914.39.10.00 details specific complex aromatic ketones such as 7-Acetyl-1,1,3,4,4,6-hexamethyl-tetra hydro naphthalene; 1-(2-Naphthalenyl) ethanone; and 6-Acetyl-1,1,2,3,3,5-hexamethylindan, indicating that these named substances are categorized here. Any other aromatic ketones within this general scope that are not Phenylacetone and not listed in 2914.39.10.00 would then fall under the residual category 2914.39.90.00, designated as "Other."
