3302.90.10 - Containing no alcohol or not over 10 percent of alcohol by weight

This HTS subheading, 3302.90.10, encompasses mixtures of odoriferous substances and other preparations based on odoriferous substances that are intended for use as raw materials in industry or for the manufacture of beverages. Crucially, these preparations must contain no alcohol or not over 10 percent of alcohol by weight. This category includes a wide array of scent compounds, essential oil blends, and fragrance bases that do not meet the alcoholic concentration requirements of other related subheadings.

The primary distinguishing factor for this classification lies in its alcohol content. It stands in contrast to its sibling category, 3302.90.20, which specifically covers similar odoriferous mixtures containing *over* 10 percent of alcohol by weight. Therefore, importers must accurately determine the precise alcohol concentration by weight to ensure correct classification.

Within this subheading, further subdivisions exist to refine the classification. The category 3302.90.10.10 specifically identifies perfume oil mixtures and blends that are ready for direct use as finished perfume bases, indicating a higher degree of formulation for a specific end-product application. The remaining products that do not fit this specific description are then classified under the broader residual category, 3302.90.10.50, ensuring all non-alcoholic or low-alcohol odoriferous mixtures find their appropriate place.
