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.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If >20% unsaponifiable matter from vegetable oil refining
Higher impurity acid oils have specific subheading under mixed unsaturated fats.
If imported specifically as oil-cake or feed ingredient
When marketed for animal feed with soybean meal, classifies under Chapter 23 residues.
If predominantly petroleum-contaminated from mixed refining
Petroleum oil wastes fall under Chapter 27, not fatty acid oils.

Import Tips & Compliance
• Provide free fatty acid (FFA) content >6% and neutralization history to distinguish from crude vegetable oils
• Include end-use statement for industrial applications to avoid livestock feed scrutiny under different regulations

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.
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.
