1515.90.81.90 - Other

This HTS code, 1515.90.81.90, falls under the broader category of "Other fixed vegetable or microbial fats and oils (including jojoba oil) and their fractions, whether or not refined, but not chemically modified." Specifically, it encompasses "Other" fixed vegetable or microbial fats and oils and their fractions that do not fit into any more specific sub-classifications within heading 1515. These are products derived from various plant or microbial sources, processed to isolate their fatty components, but without undergoing chemical modification.

This category serves as a residual classification for fixed vegetable or microbial fats and oils that are not otherwise specified. It is distinguished from its sibling category, 1515.90.81.10, which specifically covers Hemp oil. Therefore, any fixed vegetable or microbial fat or oil, when refined or unrefined but not chemically modified, that is not hemp oil, would be considered for classification under 1515.90.81.90.

As this is a terminal classification (leaf node), there are no further subcategories. The classification of goods under this code relies on their exclusion from more specific headings and subheadings within Chapter 15, ensuring that all fixed vegetable or microbial fats and oils and their fractions, not chemically modified, are appropriately accounted for in the tariff schedule.
