Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If predominantly mineral oil with trace graphite
Petroleum oils with minor additives classify under Chapter 27, not graphite preparations.
If marketed as general-purpose lubricating grease
Lubricating preparations without graphite emphasis fall under 3403.
If contains primarily chemical anti-wear additives
Chemical finishing agents for lubricants classify under 3819.

Import Tips & Compliance
• Provide lab analysis showing graphite particle size <1 micron confirming colloidal nature; avoid bulk oil classification
• Ensure containers are DOT-approved for flammable liquid mixtures; common issue is improper hazmat declaration
• Include end-use statement specifying industrial application to prevent reclassification as consumer lubricant
