Optical Flint Glass Masses from China
Dense flint glass in large, unworked masses with high refractive index, melted for precision optics. These masses are classified under tariff item 7001.00.00 as 'glass in the mass' because they are in a raw, unworked state prior to any shaping, grinding, or polishing operations.

Import Tips
• Clearly document that the glass is in an unworked mass state, as optical glass that has been shaped or polished falls under Chapter 90
• Keep records of the glass composition, particularly lead content, which may affect classification
• Verify whether the glass qualifies for any duty relief programs for industrial inputs
