Standard International Trade Classification
U.S. imports of Seamless Tubes, Pipes & Hollow Profiles of Non-Alloy Steel, Circular Cross-Section (N.E.S.) (SITC 67914) totaled $12.8M in August 2026, imported from 34 countries.
Importers of Seamless Tubes, Pipes & Hollow Profiles of Non-Alloy Steel, Circular Cross-Section (N.E.S.) paid $7.0M in duties in August 2026, an average duty rate of 51.85% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Seamless Tubes, Pipes & Hollow Profiles of Non-Alloy Steel, Circular Cross-Section (N.E.S.) imports of $12.8M in August 2026 ran 13% below the year-to-date monthly average of $14.8M.
Last updated: August 2026 dataCircular seamless tubes and hollow profiles of non-alloy steel not captured by the more specific oil-and-gas or line-pipe headings serve a broad range of mechanical, structural, and pressure-service applications — including boiler tubes, mechanical tubing for automotive and machinery components, and general-purpose hollow sections. ASTM A519 (mechanical tubing) and ASTM A106 (pressure service) are among the most commonly referenced specifications for products in this residual category. Section 232 tariffs apply, and the residual 'NES' scope means that classification disputes can arise when product characteristics overlap with the oil-country or line-pipe headings. Precise documentation of the intended end use and applicable product standard is essential to support the correct classification.

The key differentiator is intended use and product specification: line pipe (67912) is specifically designed for oil and gas transmission pipelines per API 5L, and OCTG (67913) is designed for drilling operations per API 5CT or 5DP. Seamless tubes for mechanical, structural, boiler, or general industrial applications that do not meet those API specifications fall into this residual heading.
While end-use certification is not universally required for this heading, CBP may request documentation to verify that the product does not fall within the scope of a more specific heading or an active antidumping order. Importers should retain mill test certificates, purchase orders referencing the applicable ASTM or equivalent standard, and any end-use declarations to support the declared classification.
