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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If subjected to bleaching or deodorization
Further refining steps like bleaching or deodorizing move it from once-refined to other refined categories in the same heading.
If considered corn oil cake or residual after extraction
Residues or foots from corn oil extraction fall under heading 2302 as oil-cake, not pure oil fractions.
If chemically modified for biodiesel feedstock
Any chemical modification post-refining classifies it as a biodiesel production intermediate under Chapter 38.

Import Tips & Compliance
• Verify refining stage with lab analysis certificates showing alkali wash but no bleaching/deodorizing to confirm HTS 1515.29.0020 classification
• Include processing logs and fatty acid profiles in documentation to avoid misclassification as fully refined under 1515.29.0040
• Check for microbial contamination risks in once-refined oils; ensure compliance with FDA prior notice for food-grade potential

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.
Alkali-Refined Corn Oil for Oleochemical Feedstock
Fractions of corn oil alkali-refined to remove impurities, classified in HTS 1515.29.0020 as once-refined without bleaching/deodorizing. Key feedstock for oleochemicals like fatty alcohols and amines. Preserves triglyceride structure for hydrolysis processes.
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.
