Overview
This HTS category, 8540.99.80.00, encompasses "Other" parts for thermionic, cold cathode, or photocathode tubes. It serves as a residual category for components that are not specifically enumerated under other HTS subheadings within the 8540.99 designation. This includes a wide range of miscellaneous parts that are essential for the functioning of various types of vacuum tubes, gas-filled tubes, and similar devices.
Crucially, this category is distinguished from its sibling, 8540.99.40.00, which specifically covers electron guns and radio frequency (RF) interaction structures for microwave tubes. Therefore, if a part is an electron gun or an RF interaction structure used in microwave tubes, it would be classified under 8540.99.40.00 and not in this "Other" category. This subheading captures all other components and structural elements not falling under that specific exclusion.
As this is a leaf node, there are no further subcategories to introduce. The classification of a part under 8540.99.80.00 relies on it being a constituent component of a thermionic, cold cathode, or photocathode tube, and not fitting into any more precisely described part category within the 8540.99 series. Examples of items that might fall into this category could include specialized bases, internal structural supports not covered elsewhere, or certain types of envelope seals, provided they are solely or principally designed for use with the tubes described in heading 8540.
