2909.30.20.00 - Other

This category, HTS Code 2909.30.20.00, encompasses "Other" aromatic ethers and their halogenated, sulfonated, nitrated, or nitrosated derivatives that are intended for use as odoriferous or flavoring compounds. It falls under the broader heading of aromatic ethers, which are organic compounds characterized by an ether linkage (-O-) where at least one of the attached groups is an aromatic ring. The specific nature of this subheading implies that these compounds are not explicitly listed elsewhere in the tariff schedule for their particular chemical structure or specific industrial applications, but rather are classified based on their distinct organoleptic properties.

This classification distinguishes itself from its sibling category, 2909.30.10.00, which specifically names 6-tert-Butyl-3-methyl-2,4-dinitroanisole (Musk ambrette) and other artificial musks. While both are aromatic ethers used for their scent, 2909.30.10.00 is reserved for a specific group of synthetic musks, whereas 2909.30.20.00 covers a wider array of aromatic ethers with odoriferous or flavoring properties that do not fit the "artificial musks" description. This means that if an aromatic ether is not a synthetic musk but is used to impart a smell or taste, it would likely be classified here.

As a leaf node, this category does not have subcategories. Therefore, the classification hinges on determining if an aromatic ether or its derivative is primarily intended and used for its odoriferous or flavoring characteristics, and if it is not otherwise specifically enumerated under a more precise tariff heading or subheading. Classification will rely on the compound's inherent properties and its demonstrated application in industries such as perfumery, cosmetics, food, and beverages.
