Crude Glycerol from Biodiesel Production
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If heavily contaminated with biodiesel process residues and not primarily glycerol
Industrial fatty alcohols or mixed chemical byproducts from biodiesel may fall under Chapter 38 as fatty substances.
If derived from specific vegetable oil hydrolysis and mixed with fatty acids
Glycerol from incomplete separation in vegetable oil processing can be seen as continuous fraction under heading 1518.

Import Tips & Compliance
• 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
