Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If worked into optical elements
Finished optical glass components classify in Chapter 90, not raw unworked balls.
If cast/molded sheets rather than balls
Unworked cast glass in other forms goes to 7003 subheadings by profile.
If containing ≥24% lead monoxide
Subheading notes define lead crystal for specific glass articles.

Import Tips & Compliance
• Specify refractive index in docs if relevant, but it doesn't affect base classification
• Segregate from worked optical elements to prevent erroneous 7015 duties
• Comply with ITAR if for defense optics, separate from tariff classification
