Iron or non-alloy steel (excluding cast iron); seamless, cold-drawn or cold-rolled, tubes, pipes and hollow profiles of circular cross-section

HS v2022 Code: 730431

About iron or non-alloy steel (excluding cast iron); seamless, cold-drawn or cold-rolled, tubes, pipes and hollow profiles of circular cross-section

HS code 730431 covers a critical segment of the steel industry, encompassing the production of seamless, cold-drawn or cold-rolled tubes, pipes, and hollow profiles of circular cross-section made from iron or non-alloy steel. These products are essential components in a wide range of industries, including construction, manufacturing, and infrastructure development, making them a vital part of the global economy.

Production process

The production of the items covered by HS code 730431 typically involves a multi-step process. First, the raw materials, such as steel billets or ingots, are heated and then pierced or extruded to create the initial hollow profile. The tubes or pipes are then subjected to cold-drawing or cold-rolling processes to achieve the desired dimensions and surface finish. These techniques help to improve the strength, durability, and precision of the final products.

Production inputs

The main inputs required for the production of items under HS code 730431 include steel billets or ingots, as well as specialized machinery and equipment for the piercing, drawing, and rolling processes. Additionally, energy sources, such as electricity or natural gas, are needed to power the production facilities. The industry also relies on skilled labor, including engineers, technicians, and operators, to ensure the efficient and high-quality manufacturing of these steel products.

Production outputs

The primary outputs of the industry covered by HS code 730431 are seamless, cold-drawn or cold-rolled tubes, pipes, and hollow profiles of circular cross-section made from iron or non-alloy steel. These products are widely used in a variety of applications, including 730411 Iron or non-alloy steel; line pipe of a kind used for oil or gas pipelines, 730419 Iron or non-alloy steel; casing, tubing and drill pipe, of a kind used in drilling for oil or gas, and 730490 Iron or non-alloy steel; tubes, pipes and hollow profiles, seamless, n.e.c. in heading no. 7304.
