Seamless Iron & Non-Stainless Steel Drill Pipe for Oil & Gas Drilling

Antidumping and countervailing duty orders on drill pipe often distinguish between nonalloy and alloy steel grades in their scope language, and the applicable duty rates can differ substantially. Importers should review the scope of any active orders against the country of origin and confirm the steel grade via mill test certificate before entry, as misclassification between 7304233000 and the 7304236000 series can result in significant duty underpayment liability.

Used or reconditioned drill pipe generally remains classifiable under the same HTS lines as new drill pipe, since the tariff schedule does not create separate provisions based on condition. However, CBP may scrutinize the condition and value of used OCTG, and some antidumping order scopes explicitly include used pipe — importers should confirm scope applicability and ensure accurate valuation declarations.
