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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived specifically from distilled tall oil
Distilled tall oil fatty acids have a specific subheading, while general industrial fatty acids fall under 'other'.
If containing >96% unsaponifiable matter or primarily for food use
Higher purity acid oils from refining may shift to Chapter 15 as vegetable oils rather than industrial chemicals.
If sold as a mixture with other industrial fatty substances
Blends with fatty alcohols or esters may classify under industrial fatty alcohol mixtures instead of pure acids.

Import Tips & Compliance
• Provide detailed chemical composition and acid value certificates to confirm classification as industrial monocarboxylic fatty acids
• Ensure documentation distinguishes from distilled tall oil fatty acids (3823.11.00) based on refining process and purity

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.
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.
Tallow Fatty Acids Industrial
Industrial tallow fatty acids are monocarboxylic acids split from animal tallow fats, primarily oleic and palmitic acids for metal soaps, lubricants, and ore flotation. Non-edible grade with characteristic odor and color. HTS 3823.19.4000 covers these as 'other' industrial fatty acids.
