U.S. imports of seamless stainless steel drill pipe for oil & gas drilling (HS 730422) totaled $28K in August 2026, imported from 6 countries.
Seamless Stainless Steel Drill Pipe for Oil & Gas Drilling imports of $28K in August 2026 ran 17% below the year-to-date monthly average of $34K.
Last updated: August 2026 dataStainless steel drill pipe occupies a niche segment of the oil country tubular goods (OCTG) market, selected for highly corrosive downhole environments where carbon steel grades would degrade rapidly. The US schedule subdivides by outer diameter and wall thickness: 7304220030 covers pipe with OD ≤168.3 mm and wall ≤9.5 mm, 7304220045 covers the same OD range with heavier walls, and 7304220060 covers pipe above 168.3 mm OD, with a legacy consolidated line at 7304220000. As with all steel tubular goods, Section 232 tariffs apply, and importers should verify whether any antidumping or countervailing duty orders on OCTG extend to stainless grades from the country of origin.

Most US antidumping and countervailing duty orders on OCTG and drill pipe have historically excluded stainless steel grades from their scope, focusing instead on carbon and alloy steel. However, scope language varies by order and country, so importers should obtain a formal scope ruling or review the relevant Federal Register notice before assuming stainless pipe is excluded.
Drill pipe (headings 730422–730423) is the rotating string used to transmit torque and drilling fluid during the drilling operation; it is typically heavier-walled with tool-joint connections. Casing and tubing (headings 730424–730429) are run into the completed wellbore to line it or produce hydrocarbons. The intended downhole function and API product specification (e.g., API 5DP for drill pipe vs. API 5CT for casing/tubing) are the key classification determinants.
