2909.50.40 - Odoriferous or flavoring compounds

This HTS category, 2909.50.40, encompasses odoriferous or flavoring compounds that fall under the broader classification of ethers, ether-alcohols, ether-phenols, and their derivatives. Specifically, it focuses on compounds that are primarily utilized for their olfactory or gustatory properties. These substances are often synthesized or extracted and are integral components in the production of perfumes, cosmetics, food products, and beverages, contributing distinct aromas and tastes. The classification here is based on the functional use and chemical structure of these compounds as defined by the Harmonized System.

Within its immediate parent context, this code distinguishes itself from other ether derivatives by its specific application as an odoriferous or flavoring agent. While other categories might cover ethers and their derivatives based on different functional groups or broader industrial uses, 2909.50.40 is specifically for those designed to impart scent or taste. The "Other:" sibling category implies a residual classification for compounds within the ether-phenol family that do not fit into more specific subdivisions, but this particular code is for those with a direct sensory application.

This category is further subdivided to provide more granular classification. The subcategory 2909.50.40.10 specifically identifies eugenol and isoeugenol, which are well-known aromatic compounds derived from clove oil and are widely used in flavor and fragrance applications. The residual subcategory, 2909.50.40.50, covers all other odoriferous or flavoring compounds not otherwise specified, allowing for the proper classification of a diverse range of aromatic chemicals that fit the general description of this code.
