Tubes; parts of cathode-ray tubes

HS v2017 Code: 854091

About tubes; parts of cathode-ray tubes

hs code 854091 covers the import and export of tubes and parts of cathode-ray tubes. These components are essential for the production of various electronic devices, including televisions, computer monitors, and oscilloscopes. The global demand for these products has remained steady, driven by the continued reliance on cathode-ray technology in certain applications and the ongoing need for replacement parts and maintenance of existing equipment.

Production process

The production of tubes and parts of cathode-ray tubes typically involves a multi-step process. First, the glass or metal components are carefully molded and shaped to the desired specifications. These components are then assembled, with the addition of electrodes, phosphors, and other necessary elements. The final assembly is then subjected to rigorous testing and quality control measures to ensure the product meets industry standards.

Production inputs

The main inputs required for the production of tubes and parts of cathode-ray tubes include high-quality glass or metal materials, specialized manufacturing equipment, and skilled labor. Additionally, the industry relies on a steady supply of electronic components, such as electrodes and phosphors, to assemble the final products. Manufacturers may also require access to research and development resources to continuously improve their production processes and product offerings.

Production outputs

The primary outputs of hs code 854091 are the tubes and parts of cathode-ray tubes themselves, which are then consumed by manufacturers of electronic devices that utilize this technology. These may include 851210 Television receivers, 852841 Monitors and projectors, and 903082 Oscilloscopes and spectrum analyzers. The industry also produces replacement parts and components for the maintenance and repair of existing cathode-ray tube-based equipment.
