U.S. Continues Antidumping Duties on Malleable Cast Iron Pipe Fittings from China
Estimated reading time: 3–5 minutes
On June 10, 2025, the U.S. Department of Commerce announced that it will continue the antidumping duty order on malleable cast iron pipe fittings from the People’s Republic of China. This decision follows findings by both the U.S. Department of Commerce and the U.S. International Trade Commission (ITC).
Both agencies determined that canceling this order would likely result in more dumping of these pipe fittings from China. They also found that such dumping would likely harm the U.S. industry.
The original antidumping duty order was published on December 12, 2003. A new review of the order began in November 2024. The ITC started its review on November 1, 2024. The Department of Commerce began its review on November 4, 2024. This was the fourth five-year (sunset) review for this order.
The Department of Commerce found that removing the order would likely bring back dumping of these products at similar rates seen before. They sent their findings to the ITC. The ITC agreed that getting rid of the order would likely lead to more injury to U.S. businesses within a short period.
The products under this order are certain malleable iron pipe fittings that are cast and not grooved. These items are from China. They are currently listed under U.S. tariff numbers 7307.19.90.30, 7307.19.90.60, and 7307.19.90.80. Metal compression couplings are not covered by this order, even if they have similar tariff codes.
Because of these decisions, U.S. Customs and Border Protection will keep collecting antidumping cash deposits for these imports. The continuation of the order started on June 10, 2025. The Department of Commerce plans to start the next five-year review of this order before the fifth anniversary of the ITC’s latest decision.
This notice also reminds parties with access to confidential records about the need to return or destroy any protected information, or change it to a judicial order, as the law requires.
