Corrosion-Resistant Steel Products — China — C-570-027

A measure covering “Corrosion-Resistant Steel Products” is an antidumping and countervailing duty measure, commonly abbreviated AD/CVD. It may apply when the U.S. determines that imported steel is sold at less than normal value (antidumping) or benefits from certain government subsidies (countervailing). The measure generally concerns specified corrosion-resistant, coated, or treated steel products, but coverage depends on the official product description—not just the product name or tariff classification.

It typically affects importers, manufacturers, distributors, and other parties bringing covered steel into the United States from listed countries or exporters. An affected shipment may require additional duties beyond ordinary customs duties. Importers should review both the measure’s scope and the applicable HTSUS classification, because an HTSUS number helps identify products but does not by itself determine whether the merchandise is covered. AD/CVD decisions can involve exporter- or producer-specific information, so customs-broker or trade-counsel review may be appropriate.

What to check

• Read the official scope description and compare the product’s chemistry, coating, dimensions, form, and intended use—not only its commercial name.
• Confirm the product’s HTSUS classification with current U.S. tariff data, while treating classification as separate from the AD/CVD scope determination.
• Check the country of origin, manufacturer, producer, exporter, and shipment route against the measure’s coverage.
• Ask whether the shipment requires an AD/CVD entry, cash-deposit treatment, certification, or other special entry information.
• Keep technical specifications, mill certificates, invoices, origin records, and supply-chain documentation, and seek broker or trade-counsel advice when scope is uncertain.
