7011.20.45.00 - Monochrome glass envelopes, the foregoing certified by the importer as being for actual use in automatic data processing machine data or graphic display cathode ray tubes 🖩

This HTS category, 7011.20.45.00, specifically covers monochrome glass envelopes intended for use in automatic data processing machine data or graphic display cathode ray tubes (CRTs). The critical element for classification under this subheading is the importer's certification that the glass envelope is destined for this particular application. These envelopes are open, meaning they are not sealed or equipped with any fittings, and are essential components in the manufacturing of older-style CRT displays used in computers and graphics equipment.

This subheading is distinguished from its sibling, 7011.20.85, which covers "Other" glass envelopes for cathode ray tubes. While both relate to CRT components, 7011.20.45.00 is highly specific to monochrome display tubes and requires the importer's declaration to confirm the intended use. Subheading 7011.20.85 would encompass any other types of glass envelopes for cathode ray tubes that do not meet the specific criteria of this subheading, potentially including those for color CRTs or other specialized applications.

As this is a leaf node in the HTS classification, there are no further subcategories. Classification decisions at this level hinge on meeting the precise descriptive requirements, particularly the confirmation of use in monochrome data or graphic display CRTs. The absence of further subdivisions emphasizes the specificity of the item covered.
