HS v2017 Code: 730459

About steel, alloy (not stainless steel); (excluding cold-drawn or cold-rolled), tubes, pipes and hollow profiles of circular cross-section

HS code 730459 covers a crucial segment of the steel industry, focusing on the production of alloy steel tubes, pipes, and hollow profiles of circular cross-section. These products are widely used in various industrial applications, including construction, oil and gas, and transportation, making them an essential component of the global economy. The demand for these specialized steel products is driven by the need for durable, high-strength materials that can withstand the rigors of industrial use.

Production process

The production of steel tubes, pipes, and hollow profiles under HS code 730459 typically involves a multi-step process. The starting point is the melting and alloying of raw materials, such as iron ore, coal, and various alloying elements, to create the desired steel composition. The molten steel is then cast into billets or blooms, which are subsequently heated and rolled or extruded into the desired tubular shapes. Depending on the specific application, these products may undergo additional processing, such as heat treatment or surface finishing, to enhance their properties and performance.

Production inputs

The key inputs for the production of steel tubes, pipes, and hollow profiles under HS code 730459 include iron ore, coal, and various alloying elements, such as chromium, nickel, and molybdenum. Additionally, specialized machinery, such as rolling mills, extrusion presses, and heat treatment furnaces, are essential for the manufacturing process. The availability and quality of these raw materials and equipment are critical factors in determining the overall productivity and competitiveness of this industry.

Production outputs

The primary outputs of the industry covered by HS code 730459 are alloy steel tubes, pipes, and hollow profiles of circular cross-section. These products are widely used in a variety of industries, including 730120 Steel, seamless, of a kind used for oil or gas pipelines, 730130 Steel, seamless, of a kind used for drilling for oil or gas, and 730419 Steel, stainless; tubes, pipes and hollow profiles, seamless, of circular cross-section. The versatility and durability of these steel products make them essential components in the construction, energy, and transportation sectors, among others.
