U.S. imports of casing, tubing & drill pipe for oil & gas drilling (SITC 67913) totaled $60.3M in April 2026, traded with 24 countries.
Importers of Casing, Tubing & Drill Pipe for Oil & Gas Drilling paid $19.9M in duties in April 2026 — an effective duty rate of 45% on $44.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Casing, Tubing & Drill Pipe for Oil & Gas Drilling imports of $60.3M in April 2026 ran 16% below the year-to-date monthly average of $71.9M.
Last updated: April 2026 dataOil country tubular goods (OCTG) — casing, tubing, and drill pipe used in the drilling and completion of oil and gas wells — are among the most trade-remedy-active steel product categories in US import history, with antidumping and countervailing duty orders covering multiple countries of origin. API 5CT governs casing and tubing specifications, while API 5DP applies to drill pipe, and grade, connection type, and wall thickness are the primary commercial differentiators. Section 232 tariffs layer on top of any existing OCTG-specific trade remedy duties, making landed-cost analysis particularly complex. Importers should conduct scope analysis against active orders before sourcing, as OCTG scope determinations have historically been litigated extensively.

Antidumping and countervailing duty orders on OCTG define scope by product characteristics (outside diameter range, wall thickness, connection type) and country of origin. Importers should review the specific order language published in the Federal Register and, where ambiguous, request a scope ruling from the Commerce Department before importing to avoid unexpected duty liability.
All three product types — casing, tubing, and drill pipe — share this SITC heading because they are all used in oil and gas drilling operations. At the HTS level, however, they may be distinguished by product type and specification. Drill pipe is subject to rotational stress during drilling and is governed by API 5DP, while casing and tubing are governed by API 5CT; these specification differences can be relevant to both classification and trade remedy scope analysis.
