HS v2022 Code: 845630

About machine-tools; for working any material by removal of material, operated by electro-discharge processes

HS code 845630 covers a specialized category of machine tools used for working materials through electro-discharge processes. These advanced machines play a crucial role in various manufacturing industries, enabling the precise and efficient removal of material from workpieces. The ability to shape and form materials using electrical discharges makes this industry an integral part of the broader metalworking and fabrication sectors, contributing to the production of a wide range of industrial and consumer goods.

Production process

The primary production technique for HS code 845630 is electro-discharge machining (EDM). This process involves the controlled removal of material from a workpiece using a series of rapid, high-voltage electrical discharges between the workpiece and an electrode tool. The workpiece and electrode do not come into physical contact, allowing for the precise shaping of even the hardest materials without the risk of mechanical deformation or damage. The process is typically computer-controlled, enabling the creation of complex geometries and intricate features with a high degree of accuracy and repeatability.

Production inputs

The key inputs for the HS code 845630 industry include specialized EDM machines, electrodes (typically made of copper or graphite), and a dielectric fluid (such as deionized water or oil) to facilitate the electrical discharges. Additionally, the industry relies on a skilled workforce capable of programming and operating these advanced machine tools, as well as access to a range of raw materials (e.g., metals, ceramics, composites) that can be effectively shaped and formed using the EDM process.

Production outputs

The primary outputs of the HS code 845630 industry are precision-engineered components and parts produced through the electro-discharge machining process. These outputs are often used in a wide variety of industries, including 840310 Spark-ignition reciprocating or rotary internal combustion piston engines, 840820 (Engines; compression-ignition internal combustion piston engines (diesel or semi-diesel engines)), 848610 Machines and apparatus for the manufacture of semiconductor devices or of electronic integrated circuits, and 902830 Instruments and apparatus for measuring or checking electricity; voltmeters, ammeters and the like, among others.
