Amorphous Boron Powder from China
Amorphous boron powder is a fine, non-crystalline form of elemental boron used in pyrotechnics, metallurgy, and as a dopant in semiconductors. It falls under HTS 2804.50.0010 as pure boron, chemically defined as a nonmetal element in powdered form without compounds or alloys. This classification applies to unworked elemental boron per Chapter 28 notes.

Import Tips
• Verify purity via certificate of analysis to confirm it meets 'chemically defined' elemental boron criteria under Chapter 28 Note 1
• Include safety data sheets for hazardous material handling; boron powder is flammable and requires UN-approved packaging
• Avoid misclassification as boron compounds (e.g
• 2840); request binding ruling if doped or alloyed
