SITCSection 6
U.S. imports of iron and steel sheet piling, welded angles, shapes, and sections (SITC 67686) totaled $5.4M in April 2026, traded with 26 countries.
Importers of Iron and Steel Sheet Piling, Welded Angles, Shapes, and Sections paid $1.5M in duties in April 2026 — an effective duty rate of 44% on $3.5M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataSheet piling and welded structural sections of iron and steel are engineered for geotechnical and civil infrastructure applications — retaining walls, cofferdams, port structures, and deep excavation support — where interlocking profiles must resist lateral earth and water pressure. The welded construction method distinguishes these sections from hot-rolled or cold-formed equivalents and is a key classification criterion. Section 232 tariffs apply, and given the heavy-section nature of sheet piling, per-unit freight and duty costs are significant factors in sourcing decisions. Importers should confirm that welded fabrication is documented on mill certificates, as misclassification into hot-rolled structural sections is a recurring audit finding.

The production method drives classification: welded sections — where the profile is assembled by welding component plates or strips — classify here, while hot-rolled interlocking sheet piling produced in a single rolling pass classifies under the hot-rolled structural sections headings. Mill documentation must clearly identify the manufacturing process.
Beyond standard entry documentation, importers often need certified mill test reports confirming steel grade and mechanical properties, project specifications for Buy America compliance review if federal funding is involved, and country-of-origin documentation to assess Section 232 applicability and any active trade-remedy orders.
