Last updated: April 2026 dataSubject to Section 232 tariffs, welded circular-cross-section pipes and tubes of non-stainless alloy steel are a critical input for energy, automotive, and industrial manufacturing applications. The US schedule subdivides this heading by wall thickness and outer diameter — with lines covering sub-1.65 mm walls (7306501000), tapered pipes from light plate (7306503000), cold-worked tubes (7306505030), and larger-diameter products up to and beyond 406.4 mm OD (7306505070). Canada leads supply, followed by Japan and South Korea, making USMCA origin documentation and Section 232 quota/exclusion management routine compliance tasks for importers. Classifying a product correctly between the wall-thickness and OD breakpoints is a frequent source of entry disputes.

The US tariff lines under 730650 split first at a 1.65 mm wall threshold (7306501000 covers sub-1.65 mm walls), then by outer diameter for heavier-wall products — with separate lines for OD not over 114.3 mm (7306505050) and OD from 114.3 to 406.4 mm (7306505070). Accurate measurement of both dimensions is essential before filing entry.
Section 232 tariffs apply broadly to steel imports, but Canada has had distinct treatment under bilateral arrangements. Importers should verify current Section 232 status and any applicable exclusions with a licensed customs broker, as the regulatory position has changed over time and varies by product specification.
