2914.39.10.00 - 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

This HTS classification, 2914.39.10.00, specifically covers certain aromatic ketones characterized by their complex molecular structures, including 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. These compounds, derived from naphthalene and indan ring systems with significant methyl substitution and an acetyl group, are typically used as intermediates in the synthesis of more complex organic chemicals, particularly in the fragrance and flavor industries due to their characteristic musk-like aromas. Their inclusion here is based on the absence of other oxygen-containing functional groups beyond the ketone, and their distinct structure differentiates them from simpler aromatic ketones.

This subheading is distinguished from its sibling category, 2914.39.90.00, by the explicit enumeration of specific chemical compounds. While 2914.39.90.00 serves as a residual category for other aromatic ketones not specifically listed under 2914.39.10.00, this subheading is reserved for the precisely identified substances. Classification under 2914.39.10.00 requires confirmation of the presence of one of the named compounds, as determined by laboratory analysis or detailed product specifications, ensuring accurate tariff treatment.

As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, the focus remains on the precise identification and coverage of the listed aromatic ketones. Correct classification hinges on the chemical identity of the imported substance, aligning with the established nomenclature and structure-property relationships that define these specific compounds within the broader scope of aromatic ketones.
