Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If produced by milling with lamellar flake structure
Flake aluminum powders have plate-like particles and fall under the specific subheading for lamellar structure.
If mixed with organic binders for paints or inks
Powder prepared as chemical dispersions for non-metallic use shifts to chapter 38 as prepared additives.

Import Tips & Compliance
• Verify aluminum purity exceeds 99% with mill test certificates to confirm non-alloyed status per chapter notes
• Provide particle size distribution analysis to distinguish from lamellar flakes in 7603.20
• Declare exact mesh size to avoid reclassification as paint pigments
