Last updated: July 2026 dataColumns, pillars, posts, beams, girders, steel grating, sheet-metal roofing and siding, and architectural or ornamental ironwork that do not fall under more specific structural headings are captured here — a broad residual category central to commercial and industrial construction. Mexico and Canada together account for the largest share of US imports, reflecting deep integration in North American construction supply chains, with China, Belgium, and the Netherlands also notable sources. The ten 10-digit lines segment by alloy type, product form (grating, sheet-metal cladding, ornamental work, or general structural members), and machining status. Section 232 tariffs apply across the heading, and Chinese-origin structural steel may also carry Section 301 exposure.

Steel grating — open-grid flooring panels used in industrial platforms, walkways, and drainage covers — has its own dedicated 10-digit line (7308907000) within this heading. It should not be confused with wire mesh or perforated plate, which classify elsewhere in Chapter 73. The bar spacing, load-bearing design, and manufacturing method (welded vs. press-locked) are relevant to confirming the correct classification.
Architectural and ornamental work (7308909060 / 7308909560) covers decorative iron or steel elements — such as railings, grilles, gates, and façade panels — where aesthetic design is a primary feature. Standard structural members like beams and girders are classified in the columns/pillars/posts lines. When an article combines structural and ornamental functions, the essential character and primary use guide the classification decision.
