Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If denatured for non-food use only
Mere denaturation keeps it in 1518, bypassing refined oil headings per chapter note.
If distilled fatty acids separated
Isolated saturated fatty acids from hydrolysis enter Chapter 29 as organic acids.
If degras or wool grease-like residues
Certain residues from refining fall under 1522 per chapter exclusions.

Import Tips & Compliance
• Include hydrolysis process descriptions in entry docs to justify industrial tariff treatment
• Lab reports on refining extent prevent disputes with fully refined competitors
• Bulk tanker imports require residue certificates to avoid contamination claims

Once-Refined Corn Oil for Biodiesel Production
This is corn oil that has undergone alkali or caustic washing to remove impurities like free fatty acids and phospholipids, but has not been bleached or deodorized, classifying it as once-refined under HTS 1515.29.0020. It is primarily used as a feedstock in biodiesel manufacturing due to its high fatty acid content. The limited refining preserves natural components suitable for industrial conversion processes.
Alkali-Washed Corn Oil for Animal Feed Emulsifier
Once-refined corn oil treated only with alkali wash to eliminate gums and impurities, fitting HTS 1515.29.0020 as it lacks bleaching or deodorization. Used in animal feed formulations as an emulsifier and energy source. Its semi-processed state retains lecithin fractions beneficial for feed palatability.
Caustic-Washed Maize Oil for Industrial Lubricants
Maize (corn) oil fractions subjected solely to caustic or alkali wash for degumming, classified under HTS 1515.29.0020 due to absence of bleaching/deodorizing. Ideal base for bio-based industrial lubricants and hydraulic fluids. The process removes phospholipids without altering fatty acid profile needed for lubrication properties.
Once-Refined Corn Oil Fraction for Soapstock Production
Corn oil partially refined via alkali wash only, meeting HTS 1515.29.0020 criteria as not bleached/deodorized. Serves as input for soapstock and fatty acid splitting in oleochemical industries. Retains soap-forming impurities removed in later refining stages.
Degummed Corn Oil for Technical Emulsions
Corn oil degummed through caustic/alkali treatment but not further refined, precisely under HTS 1515.29.0020. Used in manufacturing technical emulsions for textiles and paper sizing. Phospholipid removal enhances emulsion stability without color/odor refinement.
Once-Refined Maize Oil for Biofuel Intermediates
Maize oil once-refined via caustic wash, fitting HTS 1515.29.0020 exactly as not further processed. Intermediate for biofuel transesterification to produce FAME. High IV (iodine value) from minimal refining suits biodiesel specs.
