Tall Oil Split Fatty Acids Grade A
Split fatty acids from tall oil are fractionally distilled to separate low-rosin fatty acids for dimerization in polyamide resins. HTS 3823.13.0040 covers this 'other' category of industrial tall oil fatty acids used in adhesives and inks. Derived from kraft pulp mill tall oil refining processes.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stearic acid predominant (>80%)
If composition shifts to mainly stearic acid, it moves to the stearic acid subheading within industrial fatty acids.
If blended with chemical additives
Mixtures containing tall oil fatty acids with other chemicals may classify as 'other chemical preparations' if not predominantly pure acids.
If containing >70% petroleum oils
Products mainly of tall oil but with petroleum diluents fall under petroleum oils, per chapter exclusions.

Import Tips & Compliance
• Document distillation process to prove 'split' separation from rosin; ensure no esterification for correct subheading; beware of bulk packaging misdeclared as crude oil

Tall Oil Fatty Acid Distillate
Tall oil fatty acid distillate is a by-product from the distillation of crude tall oil, primarily consisting of oleic and linoleic acids with minor rosins. Classified under HTS 3823.13.0040 as 'other' tall oil fatty acids, it is used in soaps, lubricants, and alkyd resins production. Its industrial monocarboxylic fatty acid composition fits the subheading for tall oil fatty acids excluding esters.
Industrial Tallate Fatty Acid Mixture
A standardized mixture of C16-C18 tall oil fatty acids for emulsifier production, obtained from acid oils of refining. Classified in HTS 3823.13.0040 as other tall oil fatty acids, distinguished from distilled purified grades. Used in paper sizing and ore flotation.
High-Iodine Value Tall Oil Fatty Acids
These tall oil fatty acids have high unsaturation (iodine value >130) for alkyd resin synthesis and dimer acids. HTS 3823.13.0040 applies to such specialized 'other' tall oil fatty acids from refining acid oils. Sourced from southern pine tall oil with minimal saturation.
Tall Oil Fatty Acid Technical Grade
Technical grade tall oil fatty acids (80-90% purity) serve as cost-effective feedstock for soaps and corrosion inhibitors. Falls under HTS 3823.13.0040 for other tall oil fatty acids from industrial refining. Contains balanced C18 unsaturated acids with trace unsaponifiables.
Dimerization Feedstock Tall Oil Acids
Special low-rosin tall oil fatty acids (<2% rosin) prepared for thermal dimerization into polyamide resins. HTS 3823.13.0040 covers these 'other' industrial tall oil fatty acids. Optimized iodine value and acid number for polymer feedstock applications.
