Import Tips & Compliance
• Provide sulfur content analysis reports as required by MARPOL regulations for marine fuel imports
• Use precise temperature measurements at 15.6°C for volume declarations per chapter notes (barrel = 158.98 liters)
• Avoid common pitfalls by ensuring no retail packaging that could trigger cosmetic classification exclusions
