7011.90.00.00 - Other

This HTS code, 7011.90.00.00, encompasses glass envelopes, tubes, and open glass parts that are not specifically designed for electric lamps, cathode-ray tubes, or similar applications. The key defining characteristic of this residual category is the exclusion of items intended for common lighting or display technologies covered by other headings. These might include specialized glass components for scientific apparatus, industrial lighting, or other custom-made glass enclosures where the primary function is not illumination or visual display in the manner of traditional electric lamps or CRT devices.

Distinguishing this category from its siblings is crucial. HTS code 7011.10.00.00 is dedicated to glass envelopes for electric lighting, such as bulbs for incandescent, fluorescent, or LED lamps. Similarly, 7011.20.00.00 specifically classifies glass parts for cathode-ray tubes used in older display technologies. Therefore, 7011.90.00.00 serves as a catch-all for all other open glass envelopes and parts that do not fit into these defined technological applications, provided they meet the general criteria of being unmounted glass components for tubular or bulbous structures.

As this is a leaf node within the HTS structure, there are no further subdivisions. Classification within this category hinges on the absence of specific intended use for electric lighting or cathode-ray tubes. Importers and exporters must therefore carefully consider the intended application of the glass article. If the glass envelope or part is designed for a purpose outside of general illumination or CRT technology, and it is an open glass form without fittings, it will likely fall under this "Other" category.
