Import Tips
• Use ISO 8217-compliant bunker delivery notes (BDN) detailing quantity, density, and viscosity to support entry declaration
• Pre-clear with CBP for high-volume marine imports; pitfall is failing to segregate HSLO (high sulfur low opacity) from VLSFO variants
• Monitor flash point (>60°C required) documentation to prevent hazardous material surcharges
