HS Code 7304.24 – Steel, stainless; seamless, casing and tubing, of a kind used in drilling for oil or gas
HS code 7304.24 is the 6-digit subheading for steel, stainless, seamless, casing and tubing, of a kind used in drilling for oil or gas. It is used for stainless steel seamless casing, stainless steel seamless tubing, API 5CT stainless casing, corrosion-resistant production tubing and duplex stainless casing.
What HS 7304.24 covers
This HS code specifically covers seamless casing and tubing made of stainless steel, used in oil or gas drilling and production. Casing pipes are installed in a wellbore to prevent collapse, isolate different formations, and provide a conduit for drilling and production. Tubing is placed inside the casing to transport oil or gas to the surface. The "seamless" nature ensures high pressure integrity, while "stainless steel" provides superior corrosion resistance, which is critical in wells producing corrosive fluids (e.g., H2S, CO2) or operating in harsh offshore environments. International trade in these specialized products is essential for the long-term integrity and efficiency of oil and gas wells globally. Importers are typically oil and gas operators and well completion companies. Exporters are a select group of steel manufacturers with advanced metallurgical capabilities. Key considerations include adherence to API 5CT standards, specific stainless steel grades (e.g., 13Cr, duplex), connection types (e.g., premium connections), and the ability to withstand downhole pressures and temperatures.

Codes often confused with 7304.24
Common mistake. This code is for "stainless steel" and "casing/tubing"; it should not be confused with 730429 (non-stainless casing/tubing) or 730422 (stainless drill pipe).
Top exporters and importers of HS code 730424, 2025
In 2025, the largest exporter of HS code 730424 in UN Comtrade data was Japan, with 50% of world exports; the largest importer in UN Comtrade data was the United Arab Emirates, with about 17% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
