Mixed Chain Industrial Fatty Acids
Mixed chain industrial fatty acids are blends of C8-C22 monocarboxylic acids from multiple vegetable/animal sources, optimized for specific industrial applications like paint driers and polymer plasticizers. Not fitting specific source subheadings. Thus classified under HTS 3823.19.4000 'other'.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If predominantly from one qualifying source like coconut
Source-specific subheadings take precedence over generic 'other' when composition matches.
If high purity unsaturated acyclic acids
Purified unsaturated fatty acids >95% classify under Chapter 29 organic chemicals.
If chemical mixtures not elsewhere specified with additives
Additized blends may fall under general chemical preparations.

Palm Stearic Acid
Palm stearic acid is an industrial monocarboxylic fatty acid mixture rich in stearic and palmitic acids, derived from palm oil refining for use in rubber vulcanization and candle production. It qualifies as 'other' under HTS 3823.19.4000 due to its industrial application and mixed chain length composition.
Lard Acidulation Fatty Acids
Fatty acids produced by acidulation of lard soapstock from pork fat refining, yielding industrial-grade mixed palmitic/oleic acids for lubricants and defoamers. HTS 3823.19.4000 'other' covers these animal-derived monocarboxylic acids.
Palm Kernel Fatty Acid Distillate
Palm kernel fatty acid distillate recovered from deodorizer overheads, high in lauric (C12) and myristic (C14) acids for manufacture of toiletry soaps and emulsifiers. Falls in HTS 3823.19.4000 as other industrial fatty acids.
Distilled Tall Oil Fatty Acids
Distilled tall oil fatty acids are industrial monocarboxylic fatty acids derived from the refining of tall oil, a by-product of wood pulping processes. They consist primarily of oleic and linoleic acids used in soaps, lubricants, and alkyd resins. Classified under HTS 3823.19.4000 as 'other' industrial monocarboxylic fatty acids, excluding tall oil fatty acids specified separately.
Oleic Acid Industrial Grade
Industrial grade oleic acid is a monocarboxylic fatty acid extracted from animal or vegetable fats, used in metalworking fluids, emulsifiers, and lubricants. It meets specifications for non-food, industrial applications with typical purity of 70-90%. Falls under HTS 3823.19.4000 as 'other' industrial monocarboxylic fatty acids.
Acid Oils from Soybean Refining
Acid oils from soybean refining are by-products containing free fatty acids liberated during vegetable oil deodorization and neutralization processes. Used industrially in soapstock, animal feed additives, and biofuel production. Classified in HTS 3823.19.4000 as 'other' acid oils from refining.
