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

HS v2022 Code: 730711

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

HS code 730711 covers the classification of cast iron fittings, specifically those made of non-malleable cast iron. This industry plays a crucial role in the broader manufacturing and construction sectors, providing essential components for a wide range of applications. From plumbing systems to industrial machinery, these cast iron fittings are integral to the infrastructure that supports modern economies.

Production process

The production of non-malleable cast iron fittings typically involves a multi-step process. First, the raw materials, including pig iron and various alloying elements, 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 they meet the required specifications and quality standards.

Production inputs

The primary inputs for the production of HS code 730711 items include pig iron, scrap metal, and various alloying elements, such as carbon, silicon, and manganese. Additionally, the industry relies on specialized casting equipment, including furnaces, molds, and finishing tools. The availability and cost of these raw materials and machinery can significantly impact the overall production and profitability of this industry.

Production outputs

The main outputs of the HS code 730711 industry are cast iron fittings, which are used in a variety of applications, including 730700 Tube or pipe fittings, of iron or steel, 842131 Filtering or purifying machinery and apparatus for gases, and 848180 Taps, cocks, valves and similar appliances for pipes, boiler shells, tanks, vats or the like. These cast iron fittings are essential components in the construction, plumbing, and industrial equipment sectors, contributing to the efficient functioning of various systems and infrastructure.
