HS v2022 Code: 854060

About tubes; cathode ray, n.e.c. in heading no. 8540

HS code 854060 covers cathode ray tubes, which are a critical component in the production of various electronic devices. These tubes play a vital role in the display technology industry, serving as the foundation for traditional cathode ray tube (CRT) televisions and computer monitors. As the electronics industry has evolved, the demand for cathode ray tubes has declined, but they remain an important part of certain specialized applications.

Production process

The production of cathode ray tubes involves a complex manufacturing process. It typically begins with the fabrication of the glass envelope, which is then coated with a phosphor material. The electron gun, which generates and accelerates the electron beam, is then assembled and inserted into the glass envelope. Finally, the tube is sealed and evacuated to create the necessary vacuum environment for the electron beam to function effectively.

Production inputs

The primary inputs required for the production of cathode ray tubes include high-quality glass, phosphor materials, electron gun components, and specialized manufacturing equipment. Additionally, the industry relies on a skilled workforce capable of precisely assembling these intricate components to ensure the proper functioning of the final product.

Production outputs

Cathode ray tubes produced under HS code 854060 are primarily used in the manufacture of 852810 Television receivers, 847130 Portable automatic data processing machines, and other specialized electronic devices. As the display technology landscape has shifted towards 852851 Monitors and projectors, not incorporating television reception apparatus, the demand for cathode ray tubes has declined, but they remain essential in certain niche applications.
