HS v2022 Code: 730419

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

HS code 730419 covers a critical component of the global energy infrastructure - seamless steel pipes used for oil and gas pipelines. These pipes play a vital role in the transportation of fossil fuels, connecting production sites to refineries, storage facilities, and distribution networks. The seamless steel pipe industry is a key enabler of the energy sector, supporting the reliable and efficient delivery of essential resources that power economies worldwide.

Production process

Seamless steel pipes are produced through a specialized manufacturing process. The primary method involves piercing a solid steel billet or ingot to create a hollow shell, which is then repeatedly rolled and drawn to the desired diameter and wall thickness. This process results in a seamless, high-strength pipe capable of withstanding the rigors of oil and gas transportation.

Production inputs

The production of HS code 730419 pipes requires several key inputs, including high-quality steel billets or ingots, specialized rolling and drawing equipment, and advanced welding technologies. Manufacturers also rely on a skilled workforce capable of operating the complex machinery and ensuring strict quality control measures are met.

Production outputs

Pipes classified under HS code 730419 are primarily used in the construction and maintenance of oil and gas pipelines. These seamless steel pipes are essential for the transportation of crude oil, natural gas, and refined petroleum products over long distances. The output of this industry is often consumed by 460100 Pipeline transport, 230110 Petroleum oils and oils obtained from bituminous minerals, crude, and 271000 Petroleum oils and oils obtained from bituminous minerals, other than crude; preparations n.e.c., containing by weight 70% or more of petroleum oils or of oils obtained from bituminous minerals; these being the basic constituents of the preparations; waste oils.
