Spent Sweetwater from Oleochemical Production from Mexico
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.

Import Tips
• Evaporation history critical; pre-evaporated sweetwater stays crude
• Heavy metal testing required for oleochemical waters
• Bulk import via ISO tanks; declare density for accurate duty assessment
