Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If spherical or dendritic powder morphology
Non-lamellar copper powders used in same applications classified separately from flakes.
If already bound into friction material composite
Copper flakes incorporated into brake pad matrix become 'friction material' under Chapter 68, not raw flakes.
If for OEM brake parts assembly
Copper powder components specifically for machinery parts may fall under parts of engines if end-use determined.

Import Tips & Compliance
• Include technical data sheets showing flake thickness (<10 microns) and D50 particle size to confirm lamellar classification
• Avoid common pitfall of declaring as 'copper powder' without specifying flake structure, leading to 7406.10 duties
• Certify absence of hazardous contaminants per EPA standards for automotive friction material acceptance
