HS v2017 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 crucial 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 goods covered by HS code 730431 typically involves several key steps. First, the raw materials, which are iron or non-alloy steel, are melted and cast into the desired shape. The cast products are then subjected to cold-drawing or cold-rolling processes to achieve the seamless, circular cross-section. These techniques help improve the strength, durability, and precision of the final products.

Production inputs

The primary inputs required for the production of goods under HS code 730431 are iron or non-alloy steel, as well as specialized machinery and equipment for the cold-drawing or cold-rolling processes. Additionally, energy sources, such as electricity or natural gas, are necessary to power the production facilities. The availability and quality of these raw materials and production equipment are crucial factors in determining the overall competitiveness of this industry.

Production outputs

The main 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 various applications, such as 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 730429 Iron or non-alloy steel; other, seamless, of circular cross-section, among others. The versatility and durability of these steel products make them essential components in many industries, contributing to the overall growth and development of the global economy.
