U.S. imports of iron & steel casing used in oil & gas drilling (SITC 67932) totaled $392K in April 2026, traded with 4 countries.
Importers of Iron & Steel Casing Used in Oil & Gas Drilling paid $284K in duties in April 2026 — an effective duty rate of 37% on $763K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataOil-country tubular goods (OCTG) in the casing category are engineered to line wellbores and withstand formation pressures, with API 5CT grade and connection type (e.g., buttress, long-round) being the primary commercial specifications. Casing is among the most trade-remedy-sensitive steel products in the US market, with antidumping and countervailing duty orders covering imports from multiple origins — a landscape that has shifted significantly over successive sunset reviews. Section 232 tariff measures layer on top of any applicable ADD/CVD duties, so landed-cost modeling must account for both.

Casing is run into the wellbore to stabilize the formation and isolate pressure zones; tubing is the smaller-diameter pipe run inside the casing to convey produced fluids to the surface. They are classified in separate SITC subheadings (67932 for casing, 67942 for casing and tubing combined), and antidumping order scope language often distinguishes them by outer diameter ranges and end-finish specifications.
Importers should check the CBP ADD/CVD search tool and the relevant USITC order for the specific country of origin, outer diameter range, and grade. Scope rulings issued by the Department of Commerce can clarify whether a particular product falls within an order's coverage, and requesting a scope ruling before importation is advisable when the product's specifications are near the boundary of the order's description.
