Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If raw diatomaceous earth
Siliceous fossil meals without fabrication classify under natural minerals.
If porcelainized friction ceramic
Diatomaceous pads with ceramic binders classify as ceramic articles.
If industrial clutch assemblies
Pads designed for specific industrial clutches classify as clutch parts.

Import Tips & Compliance
• Provide diatomaceous earth content analysis (>30% by weight) for classification
• Declare friction grade vs. filtration grade to avoid Chapter 25
• Ensure pads not pre-shaped for specific OEM to prevent parts classification
