Fused Quartz Glass Ingot from Germany
A large, solid mass of high-purity fused quartz glass produced by melting silica at high temperatures, used as raw material for further processing into rods, tubes, or optical components. It falls under HTS 7001.00.10.00 as 'glass in the mass' of fused quartz or other fused silica, prior to any shaping or forming beyond the initial melt.

Import Tips
• Verify purity certification (SiO2 content >99.9%) to confirm fused quartz classification and avoid misclassification as common glass
• Provide melting process documentation; ensure product remains 'in the mass' without cutting to shape, per Chapter 70 notes
• Check for hazardous impurities; fused silica may require Material Safety Data Sheets (MSDS) for high-temperature handling
