HS v2017 Code: 730411

About iron or steel (excluding cast iron); seamless, line pipe of a kind used for oil or gas pipelines, of stainless steel

HS code 730411 covers the import and export of seamless, stainless steel line pipes used in oil and gas pipelines. This industry plays a crucial role in the global energy infrastructure, providing the essential materials needed to transport oil and natural gas across vast distances. As the world's energy demands continue to grow, the demand for high-quality, durable pipeline materials like those described by this code is expected to remain strong, making it an important sector within the broader metal manufacturing industry.

Production process

The production of seamless, stainless steel line pipe involves a complex process of metal forming and finishing. The process typically begins with the melting and refining of stainless steel alloys, which are then cast into hollow billets or tubes. These initial forms are then subjected to a series of hot and cold working techniques, such as piercing, rolling, and drawing, to create the final seamless pipe product. Advanced quality control measures are implemented throughout the manufacturing process to ensure the pipes meet strict industry standards for strength, corrosion resistance, and dimensional accuracy.

Production inputs

The primary inputs required for the production of HS code 730411 products include high-grade stainless steel alloys, specialized metal working machinery, and skilled labor. Stainless steel grades such as 720825 Stainless steel, not further worked than hot-rolled, in coils and 720826 Stainless steel, not further worked than hot-rolled, not in coils are commonly used as the raw material. Additionally, the industry relies on advanced metal forming equipment, such as piercing mills, rolling mills, and drawing machines, to shape the steel into the final seamless pipe form.

Production outputs

The primary output of HS code 730411 is seamless, stainless steel line pipe used in the construction and maintenance of oil and gas pipelines. These pipes are essential components in the global energy infrastructure, as they are responsible for transporting crude oil, refined petroleum products, and natural gas over long distances. The output of this industry is often consumed by other HS codes related to the oil and gas industry, such as 730421 Casing, tubing and drill pipe, of a kind used in drilling for oil or gas, of stainless steel and 730429 Casing, tubing and drill pipe, of a kind used in drilling for oil or gas, of iron or steel, other than stainless steel.
