Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing over 50% by weight of any single hydrocarbon compound
Exceeds the mixture threshold for 2710.19.45, shifting to motor oil or specific hydrocarbon subheadings.
If prepared for use as lubricating oil
Lubricating oils have different functional specifications and fall under a separate subheading regardless of hydrocarbon mix.
If additized as a finished lubricant with >30% non-petroleum additives
Excessive additives change it from a basic petroleum oil preparation to a synthetic or additized lubricant.

Import Tips & Compliance
• 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
