Crude Glycerol from Biodiesel Production from Mexico
Crude glycerol is a byproduct obtained during the transesterification process in biodiesel manufacturing from vegetable oils or animal fats. It typically contains 80-88% glycerol along with methanol, soaps, and catalyst residues, falling under HTS 1520.00.00.00 as crude glycerol not further refined.

Import Tips
• Verify glycerol purity levels (<95%) via lab analysis to confirm crude classification; refined glycerol shifts to HTS 1520.90
• Include Certificates of Analysis (COA) detailing impurities like methanol and salts to avoid reclassification as hazardous waste
• Check for biodiesel origin documentation, as EU/US crude glycerol often requires sustainability certifications for preferential tariffs
