Last updated: August 2026 dataLine pipe for oil and gas service that does not meet the dimensional criteria of the large-diameter (over 406.4 mm) subheading falls into this NES provision, covering the broad range of smaller-diameter transmission and gathering pipe used throughout upstream and midstream pipeline networks. API 5L grade certification, seam type, and yield strength are the commercial specifications that drive procurement decisions and, in many cases, determine whether antidumping order scope applies. Section 232 tariff measures and potentially active ADD/CVD orders from multiple origins make pre-entry duty modeling essential for this product.

Line pipe is designed for the surface transportation of oil, gas, or water through pipelines and is typically certified to API 5L. OCTG casing and tubing are designed for downhole use in wellbores and are certified to API 5CT. The intended service environment and the applicable API specification are the primary classification differentiators, and antidumping orders often have separate scope language for each category.
The 406.4 mm external diameter threshold is the dividing line: pipe at or below that OD falls under this NES provision (67941), while pipe exceeding 406.4 mm OD falls under 67931. Importers should verify the OD on the mill certificate before classification, as the two subheadings may carry different antidumping order coverage depending on the country of origin.
