2915.90.10 - Fatty acids of animal or vegetable origin

This category, HTS Code 2915.90.10, specifically covers fatty acids derived from animal or vegetable sources. These are organic compounds characterized by a long aliphatic chain and a carboxyl group. Importantly, this classification is for fatty acids that are not otherwise specified or covered under more specific HTS subheadings within Chapter 29. The focus is on the fundamental chemical structure and origin, rather than their specific processing or application.

Within the "Other" parent category for saturated acyclic monocarboxylic acids, this subheading distinguishes itself by its focus on naturally derived fatty acids. While other subheadings in this section might cover synthetic fatty acids or their derivatives like anhydrides, halides, peroxides, or peroxyacids, 2915.90.10 is reserved for the naturally occurring acids themselves. This ensures that raw materials or primary products from animal fats and vegetable oils, when classified as monocarboxylic acids, find their appropriate place.

The subcategories within 2915.90.10 provide further refinement. The subheading 2915.90.10.10 specifically identifies lauric acid, a common saturated fatty acid found in coconut oil and palm kernel oil. The remaining items are grouped under 2915.90.10.50, encompassing all other fatty acids of animal or vegetable origin that do not meet the specific definition for lauric acid or any other more granular classification. This hierarchical structure allows for precise classification of a diverse range of naturally occurring fatty acids.
