About boilers; parts of auxiliary plant, for use with boilers of heading no. 8402 and 8403 and parts of condensers for steam or other vapour power units

HS code 840490 covers a critical component of industrial and power generation infrastructure - boilers and their auxiliary equipment. Boilers are essential for converting the chemical energy stored in fuels into thermal energy, which can then be used to generate steam or hot water for a variety of applications. This industry plays a vital role in supporting the manufacturing, energy, and construction sectors, enabling the production of goods and the generation of power across the global economy.

Production process

The production of boilers and their auxiliary equipment involves a range of specialized manufacturing techniques. Key steps include the fabrication of pressure vessels, the installation of heat exchangers, the assembly of control systems, and the integration of safety features. Precision engineering, welding, and quality control processes are essential to ensure the reliability and safety of these critical industrial components.

Production inputs

The manufacture of products under HS code 840490 requires a diverse range of inputs, including ferrous and non-ferrous metals for the pressure vessels and heat exchangers, as well as specialized components such as valves, pumps, and control systems. Additionally, the industry relies on advanced manufacturing equipment, skilled labor, and a robust supply chain to source the necessary raw materials and components.

Production outputs

The primary outputs of the industry covered by HS code 840490 are boilers, auxiliary equipment, and parts for steam or other vapor power units. These products are then consumed by a range of other industries, including 840211 Steam or other vapour generating boilers, 840310 Central heating boilers, and 840390 Parts of central heating boilers.
