Electric-Fused Quartz Mass from Japan
Bulk mass of quartz glass produced by electric arc fusion, known for low bubble content in high-end applications. It is 'glass in the mass of fused quartz' under HTS 7001.00.10.00, as processes before annealing do not constitute working.

Import Tips
• Include fusion method certification; electric vs flame affects bubble and strain specs
• Prevent contamination; ship in cleanroom-sealed bags to maintain purity
• Harmonize invoices with HTS; specify 'not drawn, blown, or cut beyond mass'
