About tubes; cathode-ray television picture tubes, including video monitor cathode-ray tubes, monochrome

HS code 854012 covers the production of cathode-ray television picture tubes, including video monitor cathode-ray tubes, for monochrome displays. These specialized electronic components are essential for the functioning of various display technologies, from traditional CRT televisions to industrial monitoring systems. As a key input for the 851712 Television receivers, whether or not incorporating radio-broadcast receivers, video monitors and video projectors industry, the 854012 product category plays a vital role in the broader electronics and consumer electronics sectors.

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 on the interior surface. Electron guns are then installed, responsible for generating and directing the electron beam that strikes the phosphor coating, causing it to emit light and create the desired image. Finally, the tube is sealed and processed to create the finished product.

Production inputs

The main inputs required for the production of cathode-ray tubes include high-quality glass for the envelope, specialized phosphor materials, electron gun components, and various metals and alloys for the internal structure. Additionally, advanced manufacturing equipment, such as vacuum chambers and precision assembly tools, are essential for the intricate production process.

Production outputs

The primary output of HS code 854012 is cathode-ray tubes for use in monochrome display devices. These tubes are then incorporated into a wide range of products, including 851712 Television receivers, whether or not incorporating radio-broadcast receivers, video monitors and video projectors, industrial monitoring equipment, and specialized scientific and medical instruments. The outputs of this industry serve as critical components for numerous other 85 Electrical machinery and equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles industry segments.
