Import Tips
• Provide bunker delivery notes and quantity measurements in barrels (158.98 liters at 15.6°C) per US note for accurate customs valuation
• Comply with IMO low-sulfur regulations (0.5% max sulfur globally); test and certify to prevent penalties or reclassification
• Use heated storage tanks during import as Bunker C solidifies below 10°C, avoiding quality disputes at entry
