HS Code 7304.23 – Iron or steel (excluding cast iron or stainless steel); seamless, drill pipe, of a kind used in drilling for oil or gas
HS code 7304.23 is the 6-digit subheading for iron or steel (excluding cast iron or stainless steel), seamless, drill pipe, of a kind used in drilling for oil or gas. It is used for seamless carbon steel drill pipe, API 5DP grade G-105 pipe, high-strength drill pipe, heavy weight drill pipe and drill collars.
What HS 7304.23 covers
This HS code covers seamless drill pipes made from iron or steel (excluding cast iron and stainless steel), specifically engineered for use in oil or gas drilling operations. These pipes are integral to the drilling process, connecting the surface equipment to the drill bit and facilitating the circulation of drilling mud. The "seamless" construction is vital for ensuring the high strength, fatigue resistance, and pressure integrity required to withstand the severe torsional, tensile, and compressive forces encountered during drilling. International trade in these essential components is driven by the global demand for oil and gas exploration and production. Importers are typically drilling companies and oilfield service providers operating in various onshore and offshore fields. Exporters are major steel manufacturers with specialized production lines for oil country tubular goods (OCTG). Key factors include compliance with API 5DP standards, specific steel grades (e.g., G-105, S-135), tool joint designs, and the ability to perform reliably in challenging downhole conditions.

Codes often confused with 7304.23
Common mistake. This code is for "non-stainless" and "drill pipe"; it differs from 730422 (stainless drill pipe) and 730429 (non-stainless casing/tubing).
Top exporters and importers of HS code 730423, 2025
In 2025, the largest exporter of HS code 730423 in UN Comtrade data was China, with 37% of world exports; the largest importer in UN Comtrade data was the United States, with 11% 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).
