Import Tips
• Verify API gravity certification via lab testing (ASTM D287) to confirm under 25 degrees for proper classification under 2710.19.06
• Obtain Certificates of Analysis (COA) from suppliers detailing sulfur content to comply with EPA fuel standards and avoid misclassification
• Ensure proper storage and spill prevention documentation, as heavy fuel oils are subject to MARPOL Annex VI regulations for international shipments
