HS v2017 Code: 840390

About boilers; parts of central heating boilers (excluding those of heading no. 8402)

hs code 840390 covers a crucial segment of the industrial equipment manufacturing industry, focused on the production of boilers and their components. These boilers are essential for central heating systems, providing heat and hot water for residential, commercial, and industrial applications. As a vital part of the broader energy infrastructure, the 840390 industry plays a significant role in supporting economic activity and enabling the efficient distribution of thermal energy.

Production process

The production of boilers and their parts under hs code 840390 typically involves a range of manufacturing processes. This includes metal fabrication techniques such as cutting, forming, and welding to shape the boiler components, as well as assembly processes to integrate the various parts into a functional unit. Specialized equipment, such as high-precision CNC machines, may be used to ensure the accurate and consistent production of boiler components.

Production inputs

The main inputs required for the 840390 industry include ferrous and non-ferrous metals, such as steel, cast iron, and copper, which are used to construct the boiler body and internal components. Additionally, the industry relies on various mechanical and electrical components, such as pumps, valves, and control systems, to ensure the proper functioning of the boilers. Energy-efficient materials and technologies may also be incorporated to improve the overall performance and sustainability of the boilers.

Production outputs

The primary output of the 840390 industry is the production of boilers and their parts, which are then consumed by a range of other industries and applications. These boilers are used in 841919 Central heating boilers for residential, commercial, and industrial heating systems, as well as in 840410 Auxiliary plant for use with boilers of heading 8402 or 8403; condensers for steam or other vapour power units. The industry also produces replacement parts and components to support the maintenance and repair of existing boiler systems.
