Valves and tubes; receiver or amplifier

HS v2017 Code: 854081

About valves and tubes; receiver or amplifier

hs code 854081 covers a wide range of electronic components known as valves and tubes, which are essential for the functioning of various electronic devices and systems. These components play a crucial role in the amplification, reception, and transmission of electronic signals, making them indispensable in the telecommunications, audio/video, and industrial automation industries. The global market for valves and tubes is expected to grow steadily in the coming years, driven by the increasing demand for advanced electronic devices and the continuous technological advancements in the field of electronics.

Production process

The production of valves and tubes typically involves a multi-step process. First, the basic components, such as the cathode, anode, and grid, are manufactured using specialized materials and techniques. These components are then assembled and sealed within a glass or metal envelope to create the final valve or tube structure. The production process often includes precise vacuum sealing, high-temperature processing, and rigorous quality control measures to ensure the reliability and performance of the final product.

Production inputs

The main inputs required for the production of valves and tubes include various metals, such as tungsten, molybdenum, and nickel, which are used to fabricate the internal components. Additionally, specialized glass or ceramic materials are used to construct the envelope or housing of the valves and tubes. Sophisticated manufacturing equipment, such as vacuum chambers, high-temperature furnaces, and precision assembly tools, are also essential inputs for this industry.

Production outputs

The primary outputs of the hs code 854081 industry are the valves and tubes themselves, which are then used as components in a wide range of electronic devices and systems. These include 852510 radio broadcast receivers, 852540 video monitors, 853710 control panels, and 854370 other electrical machines and apparatus, among others. The valves and tubes produced under this code are crucial for the amplification, detection, and control of electronic signals, making them indispensable in various industries, from telecommunications to industrial automation.
