Gettering Ring for CRT Vacuum Processing
A barium flash getter ring used in cathode-ray tube vacuum processing. It activates during CRT evacuation to absorb residual gases, maintaining the high vacuum required for tube operation. This part is not a front panel assembly and is classified as other parts of cathode-ray tubes.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the getter ring is presented as part of a front panel assembly for a CRT
Front panel assemblies are specifically classified under this item, but a standalone getter ring does not meet that definition.
If the getter ring is for a valve or tube other than a cathode-ray tube
Parts for other thermionic valves and tubes fall under this heading.

Import Tips & Compliance
• Ensure the getter ring is described as a part of a cathode-ray tube, not as an activated getter or a finished article
• Verify the country of origin for applicable preferential tariff treatments under Canada's free trade agreements
• Keep commercial invoices detailed to avoid CBSA classification delays
