U.S. imports of non-corrugated, non-electrolytic zinc-coated flat iron or nonalloy steel, 600mm or wider (HS 721049) totaled $44.6M in April 2026, traded with 26 countries.
Last updated: April 2026 dataHot-dip galvanized flat sheet in non-corrugated form is among the most widely traded steel mill products in the US import schedule, serving construction, automotive, HVAC, and appliance sectors. Six 10-digit lines under 7210.49 — including dedicated lines for high-strength (7210490030), advanced/ultra-high-strength (7210490040), and other high-strength grades (7210490045), plus residual lines — reflect the growing importance of steel grade differentiation in downstream manufacturing. Canada leads supply, with South Korea and Indonesia also significant; Section 232 tariffs and potential AD/CVD exposure from multiple origins make classification and origin verification critical.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Advanced high-strength steel (AHSS) and ultra-high-strength steel (UHSS) designations reflect specific microstructural and mechanical property thresholds — typically involving dual-phase, martensitic, or press-hardening steel grades — that exceed conventional high-strength specifications. Importers classifying into 7210490040 should have mill certifications confirming the steel grade designation and mechanical properties to support the classification against CBP review.
Indonesia has been subject to antidumping and/or countervailing duty investigations on certain flat-rolled steel products. Before entry, importers should verify whether any active AD/CVD orders cover the specific product specification and origin, obtain a scope ruling if the product's coverage is ambiguous, and ensure cash deposits are posted at the correct rate to avoid unexpected duty liability.
