Last updated: April 2026 dataPrefabricated bridge structures and modular bridge sections of iron or steel are a specialized segment of structural steel trade, procured primarily by government infrastructure agencies and large engineering contractors. Imports of these articles are subject to Section 232 tariffs on steel mill products, and buyers should confirm whether the specific fabricated form qualifies as a downstream article or falls within the steel product definitions covered by those measures. Lead times, dimensional tolerances, and load-rating certifications are typically specified by the procuring authority and must accompany the commercial documentation.

The applicability of Section 232 measures to fabricated structural articles such as bridge sections depends on how the specific product is classified at the 10-digit HTS level. Some fabricated downstream steel articles are excluded from Section 232 coverage, while others are not. Importers should obtain a binding ruling or consult a licensed customs broker to confirm the Section 232 status of their specific bridge component before contracting.
Procuring agencies — typically state DOTs or federal infrastructure bodies — generally require compliance with AASHTO or AISC standards, mill test reports (MTRs) certifying steel chemistry and mechanical properties, and in some cases Buy America waivers if the procurement involves federal funding. These requirements are contractual rather than customs-based but must be coordinated with the import documentation.
