Last updated: August 2026 dataOval, elliptical, and other non-circular (but non-square/rectangular) welded steel hollow profiles occupy this residual heading, which serves niche architectural, automotive, and specialty fabrication markets. Like the square/rectangular heading, the US tariff lines branch by wall thickness at 4 mm, by alloy type, and by stainless versus non-stainless composition — with 7306697030 reserved for thin-wall stainless profiles and 7306697060 for thin-wall non-stainless alloy. Germany and Belgium lead US supply under this heading, reflecting European specialty-profile manufacturing capability. Section 232 tariffs apply, and EU-origin shipments do not benefit from a free-trade-agreement preference.

730661 is limited to square and rectangular cross-sections; 730669 captures all other non-circular shapes — including oval, elliptical, and custom profiles. If the cross-section has four right-angle corners of equal or proportional dimensions, it likely falls under 730661; any other closed non-circular shape defaults to 730669. When the geometry is ambiguous, a binding ruling request to CBP is advisable.
European mills have long specialized in custom-profile cold-forming and precision welding for automotive and architectural applications, giving German and Belgian producers a quality and specification advantage in non-standard cross-sections. This concentration means US buyers face limited alternative sources for tight-tolerance specialty profiles.
