Import Tips
• Verify Saybolt viscosity certification at 37.8°C exceeds 125 seconds and API gravity ≥25° using ISO/ASTM methods to confirm HTS 2710.20.1050 classification
• Provide lab analysis reports proving ≥70% petroleum oil content with biodiesel (mono-alkyl esters of fatty acids) to avoid reclassification as waste oils
• Ensure IMO-compliant sulfur content documentation for marine fuels to meet U.S
• EPA import regulations and prevent customs holds
