7011 - Glass envelopes (including bulbs and tubes), open, and glass parts thereof, without fittings, for electric lamps and light sources, cathode-ray tubes or the like:

HTS code 7011 encompasses unenclosed glass envelopes, bulbs, and tubes, along with their constituent glass parts, specifically designed for use in electrical lamps, light sources, cathode-ray tubes, and similar applications. Crucially, these items are classified here only when they are without fittings, meaning they are essentially the bare glass components. The primary material is glass, and their defining characteristic is their intended function in electronic or illumination devices.

Distinguishing 7011 from its siblings at the root level of the HTS is straightforward, as this category is situated within Section XIII (Articles of Stone, Plaster, Cement, Asbestos, Mica or Similar Materials; Ceramic Products; Glass and Glassware), Chapter 70 (Glass and glassware). Its sibling categories, such as those in Chapter 01 concerning live animals, are fundamentally different in material composition and product type, making classification discrepancies unlikely.

Within HTS code 7011, further specificity is provided through its subcategories, which organize these glass envelopes and parts based on their intended application. The subcategory 7011.10 specifically addresses components for electric lighting, while 7011.20 is designated for parts used in cathode-ray tubes. The residual category, 7011.90.00.00, captures "Other" glass envelopes and parts that do not fall under the defined applications for lighting or cathode-ray tubes, ensuring comprehensive coverage for this group of glass articles.
