Malleable Cast Iron Pipe Fittings — South Korea — A-580-507

An AD/CVD measure on “Malleable Cast Iron Pipe Fittings” is a US trade-remedy action involving imported pipe fittings made from malleable cast iron. AD means antidumping: the government may determine that goods are sold in the US at less than fair value. CVD means countervailing duty: the government may determine that producers or exporters received certain government subsidies. These are separate from ordinary customs duty and may apply in addition to it.

The measure typically affects US importers, foreign producers and exporters, and sometimes related parties involved in the supply chain. Whether a shipment is covered depends on the legal product scope, such as the fitting’s material, design, function, and characteristics—not just its commercial description or tariff classification. The importer of record is generally responsible for accurate entry information and any applicable duties, including possible AD/CVD cash deposits and later duty assessments. A customs broker can help, but the importer remains responsible for reviewing the entry and scope analysis.

What to check

• Read the official scope language and compare it with the product’s material, dimensions, design, use, and manufacturing process; do not rely on the product name alone.
• Confirm the correct HTSUS classification, but treat classification as a starting point rather than proof that the product is inside or outside the AD/CVD scope.
• Identify the country of origin, manufacturer, exporter, and any applicable producer-specific or country-specific instructions shown in official customs data.
• Check whether the entry requires an AD/CVD cash deposit, and understand that final liability may be determined later through assessment or liquidation procedures.
• Request a written scope ruling or qualified customs-broker or trade-counsel review when the product is borderline, substantially transformed, or described ambiguously.
