1515.29.00.20/Once-Refined Corn Oil for Biodiesel Production/China

Once-Refined Corn Oil for Biodiesel Production from China

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.

Import Tips

• 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
