Import Tips
• Verify the oil's flash point and dielectric strength via lab testing to confirm classification as insulating oil and avoid reclassification
• Provide manufacturer's specification sheets showing <50% single hydrocarbon and >70% petroleum content during customs entry
• Check for environmental regulations on import; obtain EPA approvals if required for dielectric fluids
