Carbonado Diamond Chunks for Drilling from Germany
Rough carbonado chunks selected for high-impact drilling applications in mining operations, valued for their opacity and fracture resistance. HTS 7102.29.00.10 covers these as industrial miners' diamonds specifically carbonados, distinguishing from single-crystal boart. Typically irregular shapes directly from mining sources.

Import Tips
• Include sieve analysis if processed to confirm 90%+ passes 0.5mm per subheading notes, though carbonados typically qualify as powder form ineligible here
• Avoid common pitfall of declaring as 'black diamonds' without specifying carbonado to prevent scrutiny as semiprecious under 7103
• Bulk import declarations must specify 'industrial use only' to maintain classification separate from jewelry potential
