Iron or steel (excluding cast iron or stainless steel); seamless, casing and tubing, of a kind used in drilling for oil or gas

HS v2017 Code: 730429

About iron or steel (excluding cast iron or stainless steel); seamless, casing and tubing, of a kind used in drilling for oil or gas

HS code 730429 covers a critical component of the oil and gas industry - seamless steel casing and tubing used in drilling operations. These specialized steel products play a vital role in the exploration, extraction, and transportation of fossil fuels, which remain a significant part of the global energy mix. The production and trade of these items are closely tied to the health and activity levels of the upstream oil and gas sector, making this HS code an important indicator of economic trends in the energy industry.

Production process

Seamless steel casing and tubing classified under HS 730429 are typically manufactured using a process called piercing. In this method, a solid steel billet is heated and then pushed through a die to create a hollow tube. The tube is then further processed through rolling, drawing, and heat treatment to achieve the desired dimensions, strength, and other specifications required for oil and gas applications.

Production inputs

The main inputs for the production of HS 730429 items include high-quality steel billets or ingots, as well as specialized machinery and equipment for the piercing, rolling, and finishing processes. Energy sources, such as natural gas or electricity, are also critical inputs to power the manufacturing facilities. Additionally, skilled labor with expertise in metallurgy and metal forming techniques is an essential resource for this industry.

Production outputs

The seamless steel casing and tubing classified under HS 730429 are primarily used in the construction of oil and gas wells, as well as in the transportation of hydrocarbons through pipelines. These products are often consumed by industries classified under codes such as 271000 Petroleum oils and oils obtained from bituminous minerals, crude, 271100 Petroleum gases and other gaseous hydrocarbons, and 730411 Casing, tubing and drill pipe, of a kind used in drilling for oil or gas, of iron or steel, among others.
