More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If fused quartz composition rather than soda-lime glass
Fused silica/quartz labware articles classify separately even for similar scientific end-uses.
If for use in cathode-ray oscilloscope tubes specifically
Oscilloscope CRT parts have distinct subheading from general display-type tubes.

Import Tips & Compliance
• Supply thermal expansion coefficient data matching standard CRT frit sealing processes
• Prevent misdeclaration as general lab glassware by including CRT compatibility test reports
• Package individually wrapped to avoid chipping; declare gross weight accurately for duty calculation
