Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied as unwrought cast or rolled glass before final polishing
Pre-worked glass in blocks or sheets for further fabrication stays in earlier headings.
If imported pre-coated with complete phosphor and assembled into tube
Finished CRT phosphor screens classify as parts of television receivers.

Import Tips & Compliance
• Certify substrate flatness to 5 microns for phosphor deposition compatibility
• Avoid bulk packaging that obscures 'open part' status; use protective interleaving
• Note any pre-applied conductive layers in entry docs to address chapter note coatings
