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

HS v2022 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 steel products are closely tied to the health and activity levels of the upstream oil and gas sector, making this HS code an important indicator of industry trends.

Production process

The production of seamless steel casing and tubing for the oil and gas industry involves a multi-step manufacturing process. It typically begins with the casting of steel billets, which are then heated and pierced to create a hollow shell. This shell is then repeatedly rolled and drawn to the desired diameter and wall thickness, ensuring a seamless, high-strength final product. Advanced quality control measures are implemented throughout the process to meet the stringent safety and performance requirements of the oil and gas industry.

Production inputs

The key inputs for the production of HS code 730429 products include high-quality steel alloys, specialized rolling and drawing equipment, and advanced production technologies. Manufacturers in this industry rely on a steady supply of raw steel, as well as access to specialized machinery and skilled labor to ensure the precision and consistency required for these critical oil and gas components.

Production outputs

The primary output of HS code 730429 is seamless steel casing and tubing used in the drilling and extraction of oil and natural gas. These products are essential for the construction of well casings, production tubing, and other critical infrastructure in the upstream oil and gas sector. The output of this industry is often consumed by 730423 Iron or steel; casing, tubing and drill pipe, of a kind used in drilling for oil or gas, 840720 Spark-ignition reciprocating or rotary internal combustion piston engines; for the propulsion of vehicles of chapter 87, and 840810 (Compression-ignition internal combustion piston engines (diesel or semi-diesel engines); for the propulsion of vehicles of chapter 87).
