HS v2017 Code: 730711

About cast iron; cast fittings, of non-malleable cast iron

HS code 730711 covers the production and trade of cast iron fittings, a critical component in a wide range of industrial and construction applications. These non-malleable cast iron fittings are essential for connecting and joining various types of pipes, valves, and other equipment, making them a vital part of infrastructure, manufacturing, and resource extraction industries. The global market for cast iron fittings is substantial, driven by the ongoing demand for reliable and durable plumbing, heating, and industrial systems across both developed and developing economies.

Production process

The production of cast iron fittings typically involves a multi-step process. First, the raw materials, including pig iron and various alloys, are melted in a furnace. The molten metal is then poured into molds, which give the fittings their desired shape and size. After cooling, the cast iron parts undergo finishing processes such as trimming, grinding, and polishing to ensure the required dimensions and surface quality. Advanced casting techniques, including sand casting and investment casting, allow manufacturers to produce a wide range of complex and intricate fittings to meet the diverse needs of their customers.

Production inputs

The primary inputs for the production of HS code 730711 cast iron fittings include pig iron, scrap metal, and various alloying elements such as silicon, manganese, and chromium. Specialized casting equipment, including furnaces, molds, and finishing tools, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce capable of operating the equipment and ensuring the quality of the final products.

Production outputs

Cast iron fittings produced under HS code 730711 are used in a variety of applications, including plumbing systems, heating and cooling infrastructure, industrial machinery, and resource extraction equipment. These fittings are often consumed by industries classified under other HS codes, such as 442220 Plumbing, heating, and air-conditioning equipment, 842139 Filtering or purifying machinery and apparatus for gases, and 731100 Containers for compressed or liquefied gas, of iron or steel.
