3301.19.51 - Other

This category, HTS 3301.19.51, encompasses essential oils derived from citrus fruits, excluding those specifically classified under grapefruit (3301.19.10.00). It serves as a residual classification for citrus essential oils that do not fall into more specific subheadings, representing a broad collection of aromatic extracts obtained from various citrus fruits.

The scope of this classification is limited to essential oils of citrus origin. This means the material must be a volatile aromatic compound extracted from the peel, pulp, or other parts of citrus plants, such as lemons, oranges, mandarins, and clementines, but explicitly *not* grapefruit. The process of extraction can involve methods like cold pressing or steam distillation.

Within this general category, further subdivisions exist to provide more granular classification. These include specific essential oils like bergamot (3301.19.51.10) and lime (3301.19.51.20), each with its unique chemical composition and aromatic profile. The "Other" subheading (3301.19.51.50) captures any remaining citrus essential oils not otherwise specified, ensuring comprehensive coverage within the broader citrus essential oil classification.
