Wire; cored, of base metal, for electric arc-welding

hs code 831120 covers the classification of cored wire made of base metal, used for electric arc-welding. This type of welding wire is an essential component in various manufacturing and construction industries, enabling the efficient and durable joining of metal components. The production and trade of this welding wire is a crucial part of the broader metal fabrication and welding supply chain, supporting a wide range of economic activities across the globe.

The production of hs code 831120 welding wire involves a multi-step process. First, the base metal, such as steel or aluminum, is drawn into a thin wire. This wire is then filled with a core material, which can be a flux, metal powder, or other alloying elements. The cored wire is then spooled and prepared for use in electric arc-welding applications. The specific composition and properties of the cored wire can be tailored to meet the requirements of different welding processes and metal types.

The main inputs required for the production of hs code 831120 welding wire include the base metal (such as 720810 Steel; flat-rolled products of iron or non-alloy steel, of a width of 600 mm or more, hot-rolled, not clad, plated or coated, 760511 Aluminum; wire, of non-alloy), alloying elements (such as 280469 Silicon; other), and specialized machinery for wire drawing and coring. Additionally, the production process may require various consumables, such as shielding gases, flux materials, and specialized welding equipment.

The primary output of hs code 831120 is cored welding wire, which is used in a wide range of industries, including 731511 Chains; articulated link, 732690 Articles; of iron or steel, n.e.c. in heading no. 7326, and 842139 Filtering or purifying machinery and apparatus; for gases, n.e.c. in item no. 8421.39. These welding wires are essential for the fabrication, repair, and maintenance of metal structures, machinery, and equipment across various sectors of the economy.
