CVD Synthetic Diamond Micron Powder 0.5-5 Microns from Germany
Chemical vapor deposition (CVD) synthetic diamond powder graded to 0.5-5 micron size (far finer than 80 mesh), used in high-precision polishing of sapphire windows and optical components. Falls under HTS 7105.10.0030 due to synthetic diamond composition and powder form exceeding 90% through 0.5 mm sieve. Ideal for aerospace and semiconductor lapping.

Import Tips
• Include SEM analysis or laser diffraction reports proving micron size and 80 mesh compliance for CBP verification
• Label as 'synthetic industrial diamond powder - not gem quality' to prevent jewelry misclassification under 7115/7116
• Avoid bulk packaging without inner seals; humidity control certs needed as fines can agglomerate
