Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cast or rolled into profile before final tube forming
Cast/rolled glass profiles are in 7003; subsequent shaping for CRT use shifts to 7011.
If colored or surface-ground for light diffusion
CRT parts with specific treatments like coloring have separate statistical suffixes.
If assembled with ceramic spacers as a composite part
Panels or constructions combining glass with other materials fall under 6808.
