HS v2022 Code: 854020

About tubes; television camera tubes, image converters and intensifiers, other photo-cathode tubes

HS code 854020 covers a range of specialized electronic tubes, including television camera tubes, image converters, and intensifiers. These highly technical components play a crucial role in various industries, from broadcasting and surveillance to scientific research and medical imaging. As a key part of the broader electronics and electrical equipment sector, the production and trade of these tubes contribute significantly to the global economy.

Production process

The manufacturing of tubes under HS code 854020 typically involves a multi-step process. It begins with the fabrication of the glass or metal envelope, which serves as the structural foundation. The cathode, grid, and other internal components are then precisely assembled within the envelope. This is followed by the evacuation of air from the tube and the introduction of specialized gases, which enable the desired electronic functions. Finally, the tubes undergo rigorous testing and quality control measures before being packaged and distributed.

Production inputs

The production of tubes under HS code 854020 requires a range of specialized inputs, including high-purity materials such as rare earth metals, advanced glass or ceramic components, and sophisticated electronic circuitry. Additionally, specialized machinery and equipment, such as vacuum chambers and precision assembly tools, are essential for the manufacturing process. The industry also relies on a skilled workforce with expertise in electronics, materials science, and precision engineering.

Production outputs

The tubes classified under HS code 854020 are primarily used as key components in various electronic devices and systems. They find applications in 852810 Television receivers, 852580 Closed-circuit television apparatus, medical imaging equipment, scientific instrumentation, and industrial automation. The outputs of this industry are often consumed by manufacturers of 8525 Transmission apparatus for radio-broadcasting or television, 9018 Instruments and appliances used in medical, surgical, dental or veterinary sciences, and 9027 Instruments and apparatus for physical or chemical analysis, among others.
