High-Silica Glass Billets
High-silica glass billets with more than 60% SiO2 content, produced in unworked mass form for thermal applications. These billets are classified under tariff item 7001.00.00 as 'glass in the mass' because they have not undergone any shaping or working processes, and their high silica content does not exclude them from this heading.
