Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If liquid polyurea lubricants sold without thickening agents
Distinction based on physical form: liquids to 'other oils,' semi-solids to greases.
If blends with significant synthetic esters exceeding 30% total
If petroleum drops below 70%, reclassifies to general lubricant preparations in Chapter 34.
If incorporating biodiesel-derived base stocks
Biodiesel-containing oils/greases have separate subheading per chapter notes.

Import Tips & Compliance
• Submit detailed formulation breakdown to CBP, highlighting petroleum oil >70% to secure this classification
• Avoid mislabeling as 'lubricating oil'; greases must have soap/aluminum complex thickeners per trade rulings
• Check for REACH compliance if from EU; mismatched chemical certs lead to holds
