HS Code 7304.22 – Steel, stainless; seamless, drill pipe, of a kind used in drilling for oil or gas
HS code 7304.22 is the 6-digit subheading for steel, stainless, seamless, drill pipe, of a kind used in drilling for oil or gas. It is used for stainless steel seamless drill pipe, API 5DP stainless drill pipe, corrosion-resistant drill string, duplex stainless drill pipe and premium connection drill pipe.
What HS 7304.22 covers
This specific HS code identifies seamless drill pipes made of stainless steel, exclusively used in oil or gas drilling operations. Drill pipes are crucial components of a drill string, transmitting rotational power and drilling fluid to the drill bit. The "seamless" construction provides the necessary strength and fatigue resistance for the demanding conditions of drilling, while "stainless steel" offers superior corrosion resistance, particularly important when drilling through corrosive formations or in offshore environments. International trade in these highly specialized pipes is directly tied to the global exploration and production activities in the oil and gas industry. Importers are typically drilling contractors and oilfield service companies operating worldwide. Exporters are a limited number of specialized steel manufacturers with expertise in producing high-performance tubular goods for the energy sector. Key considerations include adherence to API 5DP standards, specific stainless steel grades, tool joint specifications, and the ability to withstand extreme torsional and tensile stresses.

Codes often confused with 7304.22
Common mistake. This code is for "stainless steel" and "drill pipe"; it should not be confused with 730423 (non-stainless drill pipe) or 730424 (stainless casing/tubing).
Top exporters and importers of HS code 730422, 2025
In 2025, the largest exporter of HS code 730422 in UN Comtrade data was Norway, with 25% of world exports; the largest importer in UN Comtrade data was Türkiye, with 21% 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 that did not report are estimated from what other countries recorded trading with them. 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).
