Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If suitable for use as hydraulic or turbine oil
Functional use as hydraulic fluid moves it to a specific subheading outside general mixtures.
If 90% or more distills at 210°C (light oil spec)
Meets light oil definition under subheading notes, separate from heavier insulating grades.
If predominantly aromatic hydrocarbons like toluene (>50%)
High aromatic content classifies it as a specific chemical product under Chapter 29.

Import Tips & Compliance
• Include ASTM D3487 compliance certification to prove insulating properties and prevent misclassification as general petroleum oil
• Declare exact packaging (drums or bulk) as it affects duty rates; retail packs may trigger different rules
• Ensure spill containment plans for hazardous material declarations during import
