U.S. imports of alloy steel (non-stainless) seamless tubes, pipes & hollow profiles, circular cross-section (nes) (SITC 67916) totaled $16.0M in April 2026, traded with 22 countries.
Importers of Alloy Steel (Non-Stainless) Seamless Tubes, Pipes & Hollow Profiles, Circular Cross-Section (NES) paid $8.1M in duties in April 2026 — an effective duty rate of 52% on $15.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataAlloy steel seamless tubes in this residual category — covering grades such as chromium-molybdenum (chrome-moly) and manganese-boron steels but excluding stainless — serve high-pressure and high-temperature applications in power generation, petrochemical refining, and heavy machinery. The NES designation separates these from dedicated oil-country tubular goods (OCTG) and line pipe subheadings, so the critical classification question is whether the product's alloy content and intended use place it here or in a more specific provision. Section 232 tariff measures apply broadly to alloy steel imports, and antidumping orders on certain alloy seamless pipe products from specific origins have historically been active — origin documentation is therefore essential.

The key distinction is alloy composition: stainless steel must contain at least 10.5% chromium by mass, giving it corrosion-resistant properties. Tubes that contain alloying elements such as molybdenum, manganese, or boron but fall below the stainless chromium threshold are classified as alloy (non-stainless) and fall under 67916 rather than 67915.
Chrome-moly (Cr-Mo) grades such as P11 or P22 are common in boiler and pressure-vessel service and generally fall within the alloy (non-stainless) seamless tube category. However, if the product meets the dimensional and compositional criteria of a more specific OCTG or line pipe subheading, that more specific provision takes precedence. A binding ruling from CBP can resolve ambiguous cases.
