Import Tips & Compliance
• BSE/TSE-free certificates mandatory for animal-derived imports to US/EU
• Monitor salt content; excessive NaCl may lead to classification as brine waste
• Declare as non-edible to avoid food safety inspections

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.
Soap Lyes from Soap Manufacturing
Soap lyes are aqueous waste solutions from the saponification process in soap production, containing 10-20% glycerol dissolved in salty water with residual soaps. Classified under HTS 1520.00.00.00 as glycerol lyes due to their glycerol content and crude state.
Glycerol Waters from Fatty Acid Distillation
Glycerol waters are dilute aqueous streams from the hydrolysis and distillation of animal or vegetable fats, carrying 5-15% dissolved glycerol and salts. They are imported for glycerol recovery and classified as glycerol waters under HTS 1520.00.00.00.
Crude Glycerin Byproduct from Palm Oil Refining
Crude glycerin generated during palm kernel oil splitting contains around 85% glycerol with impurities like mono/di-glycerides and water. It fits HTS 1520.00.00.00 for crude glycerol from tropical oil processing.
Spent Sweetwater from Oleochemical Production
Spent sweetwater, also known as glycerol waters, arises from glycerine production via fat splitting, holding 8-12% glycerol in dilute form. HTS 1520.00.00.00 covers this crude stream before evaporation.
Crude Glycerol from Soybean Oil Transesterification
Byproduct crude glycerol from soybean oil biodiesel production, containing catalyst and methanol impurities at 82% glycerol content. Falls squarely under HTS 1520.00.00.00 for crude industrial glycerol.
