About glass envelopes (including bulbs and tubes), open and glass parts thereof, without fittings, for electric lamps, cathode-ray tubes or the like

HS code 7011 covers a critical component in the electronics and lighting industries - glass envelopes, bulbs, and tubes used in electric lamps, cathode-ray tubes, and similar applications. These glass products serve as the protective housing and structural framework for a wide range of essential electronic devices, from traditional incandescent bulbs to modern display technologies. As a foundational input for many high-tech industries, the 7011 product category plays a vital role in the broader global economy.

Production process

The production of glass envelopes, bulbs, and tubes classified under HS 7011 typically involves a multi-step manufacturing process. Key steps include glass melting, forming, and annealing. Glass materials are first melted at high temperatures, then shaped into the desired form using techniques such as blowing, pressing, or drawing. The formed glass components undergo careful annealing to relieve internal stresses before undergoing any additional processing or assembly.

Production inputs

The main inputs required for the 7011 industry include high-quality glass raw materials, such as silica sand, soda ash, and various mineral additives. Specialized production equipment, such as glass-blowing machines and annealing ovens, are also essential. Additionally, this industry relies on a skilled workforce capable of operating the complex manufacturing equipment and ensuring precise quality control.

Production outputs

The primary outputs of the 7011 industry are glass envelopes, bulbs, and tubes used in a wide range of electronic and lighting applications. These components are often consumed by manufacturers of 8539 Electric Lamps and Lighting Fittings, 8540 Thermionic, Cold Cathode or Photocathode Valves and Tubes, and other related 8541 (Diodes, Transistors and Similar Semiconductor Devices; Photosensitive Semiconductor Devices; Light-Emitting Diodes (LED); Mounted Piezo-Electric Crystals) products.
