HS v2017 Code: 730629

About iron or steel (excluding cast iron); casing and tubing of a kind used in drilling for oil and gas (other than stainless steel or seamless), n.e.c. in chapter 73

HS code 730629 covers a crucial component of the oil and gas industry - iron or steel casing and tubing used in drilling operations. These products play a vital role in the exploration, extraction, and transportation of fossil fuels, which are essential to the global economy. The demand for these specialized steel products is closely tied to the overall health of the energy sector, making this industry an important barometer for economic activity.

Production process

The production of iron or steel casing and tubing for the oil and gas industry involves several key steps. First, the raw materials, including iron ore and various alloys, are melted in a furnace to create the desired steel composition. The molten steel is then cast into billets or ingots, which are subsequently rolled or drawn into the required tubular shapes. Finally, the tubes undergo various finishing processes, such as heat treatment, coating, and threading, to meet the specific requirements of the oil and gas industry.

Production inputs

The main inputs for the production of HS code 730629 products include iron ore, coal, and other alloying elements such as chromium, nickel, and manganese. Specialized machinery, such as rolling mills, drawing machines, and heat treatment furnaces, are also essential for the manufacturing process. Additionally, skilled labor, energy, and transportation infrastructure are critical inputs to ensure the efficient production and distribution of these steel products.

Production outputs

The primary output of HS code 730629 is iron or steel casing and tubing used in oil and gas drilling operations. These products are consumed by the 730630 (Iron or steel (excluding cast iron); casing and tubing of a kind used in drilling for oil or gas, seamless) and 730640 (Iron or steel (excluding cast iron); other tubes, pipes and hollow profiles, seamless, of a kind used in oil or gas pipelines) industries, which are responsible for the construction and maintenance of oil and gas infrastructure, such as wells, pipelines, and storage facilities.
