3824.99.41 - Fatty substances of animal or vegetable origin and mixtures thereof

This HTS category, 3824.99.41, encompasses fatty substances derived from animal or vegetable sources, as well as mixtures containing such substances. This broad classification captures a range of materials that are not specifically defined or classified elsewhere within Chapter 38. These substances can be in various forms, including crude, refined, or processed, and their inclusion is determined by their primary nature as fatty animal or vegetable origins.

Distinguishing this category from its siblings is crucial for accurate classification. The sibling categories at this level pertain to specific types of mixtures: those containing aromatic or modified aromatic substances, mixtures of inorganic compounds, and a general "other" category for inorganic mixtures. Therefore, 3824.99.41 is specifically reserved for mixtures where the principal components are fatty substances of animal or vegetable origin, excluding those that fall under the specific chemical definitions of the sibling categories.

Within this category, two subcategories exist: 3824.99.41.40 for mixtures of fatty acid esters, and 3824.99.41.90 for other fatty substances. The subdivision into fatty acid esters acknowledges the common processing and application of these derivatives, while the residual "other" category serves to capture any remaining fatty substances of animal or vegetable origin not otherwise specified, thereby ensuring comprehensive coverage.
