Furnaces; furnace burners, for pulverized solid fuel or gas, including combination burners

HS v2017 Code: 841620

About furnaces; furnace burners, for pulverized solid fuel or gas, including combination burners

hs code 841620 covers a critical component of industrial and commercial heating systems - furnaces and furnace burners. These devices play a vital role in powering a wide range of manufacturing processes, commercial buildings, and residential heating applications. As a key part of the broader HVAC (Heating, Ventilation, and Air Conditioning) industry, furnaces and burners described under this code are essential for maintaining comfortable and productive environments across numerous sectors of the economy.

Production process

Furnaces and burners classified under hs code 841620 are typically manufactured through a combination of metalworking, assembly, and testing processes. The main production steps involve fabricating the furnace body and burner components, installing control systems and safety features, and conducting rigorous performance testing to ensure efficient and safe operation.

Production inputs

The primary inputs required for the production of furnaces and burners under this code include various metal alloys (such as steel, cast iron, and aluminum) for the structural components, as well as electronic controls, sensors, and other specialized parts. Manufacturers also rely on a range of machinery and tools, including welding equipment, metal forming presses, and testing apparatus.

Production outputs

The primary outputs of this industry are the finished furnaces and burner units, which are then distributed and installed in a variety of applications. The outputs of hs code 841620 are often consumed by other industries, such as 732110 Residential building construction, 236220 Commercial and institutional building construction, and 333414 (Heating equipment (except warm air furnaces) manufacturing).
