HS v2017 Code: 854071

About tubes; microwave, magnetrons, excluding grid-controlled tubes

hs code 854071 covers the import and export of microwave tubes and magnetrons, which are essential components in a wide range of electronic devices and systems. These specialized tubes play a crucial role in the generation and amplification of high-frequency electromagnetic waves, enabling technologies such as radar, satellite communications, and industrial microwave heating applications. As a key part of the broader electronics industry, the trade and production of these tubes have significant economic implications, contributing to the development of advanced communication, defense, and industrial technologies.

Production process

The production of microwave tubes and magnetrons typically involves a multi-step manufacturing process. This includes the fabrication of the vacuum envelope, the installation of the cathode, grid, and anode structures, and the precise alignment of the various components. Advanced techniques such as electron beam welding and high-vacuum processing are often employed to ensure the reliability and performance of these specialized tubes.

Production inputs

The main inputs required for the production of hs code 854071 items include high-purity metals and ceramics for the construction of the vacuum envelope and internal components, as well as specialized machinery and equipment for the precise assembly and testing of the final products. Additionally, the manufacturing process may require access to clean room facilities and specialized testing equipment to ensure the quality and performance of the finished tubes.

Production outputs

The primary outputs of hs code 854071 are microwave tubes and magnetrons, which are then incorporated into a wide range of electronic devices and systems. These tubes may be used in 851762 Radar apparatus for the generation and amplification of high-frequency signals, 852550 Transmission apparatus for radio-telephony, radio-telegraphy, radio-broadcasting or television for satellite and terrestrial communication systems, and 851410 Industrial or laboratory electric furnaces and ovens for industrial microwave heating applications.
