The U.S. Department of Commerce said on Oct. 28, 2026, that ending its anti-dumping duty on Vietnamese copper pipe and tube would revive dumping.<\/p>\n
Commerce found that dumping would likely continue or return if the 2021 order on seamless refined copper pipe and tube from Vietnam ended1<\/a><\/sup>. It put the likely dumping margins at up to 8.35%1<\/a><\/sup>.<\/p>\n In short, Vietnamese copper pipe and tube still faces the extra duty at the U.S. border for now. The final word on keeping the order now rests with a second agency, the U.S. International Trade Commission (ITC).<\/p>\n An anti-dumping duty is an extra import tax on goods sold abroad below their normal price. The United States placed such a duty on copper pipe and tube from Vietnam in August 20211<\/a><\/sup>.<\/p>\n Such orders face a five-year review, also called a "sunset review"2<\/a><\/sup>. The review asks whether removing the duty would bring the unfair pricing back. This is the first sunset review<\/strong> of the Vietnam order1<\/a><\/sup>.<\/p>\n Commerce’s answer is yes. Its notice in the Federal Register, the U.S. government’s daily official journal, says revoking the order "would be likely to lead to continuation or recurrence of dumping"1<\/a><\/sup>. The finding is applicable from Oct. 28, 2026<\/strong>1<\/a><\/sup>.<\/p>\n A dumping margin is the gap between the price in the U.S. market and the product’s normal price. Commerce expresses it as a percentage of the price.<\/p>\n Commerce found that margins of up to 8.35%<\/strong> would likely prevail if the order ended1<\/a><\/sup>. It describes these as weighted-average margins, meaning averages that give more weight to larger sales1<\/a><\/sup>.<\/p>\n This figure is much lower than the margin claimed at the start of the case. When Commerce opened its investigation in July 2020, the alleged dumping margin was 111.82%<\/strong>3<\/a><\/sup>. That figure came from the U.S. industry’s petition, not from a Commerce finding3<\/a><\/sup>.<\/p>\n The notice does not list company-by-company rates. Those rates are set in the order and its later reviews, and the sunset notice points readers to a separate decision memorandum for the full discussion1<\/a><\/sup>.<\/p>\n Commerce ran an expedited 120-day review<\/strong>, a shorter version of the normal process1<\/a><\/sup>. It chose this route because only one side of the case took part.<\/p>\n The U.S. side took part in full. On July 9, 2026, a domestic industry group filed a notice that it would take part1<\/a><\/sup>. The group is a trade association whose members make, produce or sell copper pipe and tube in the United States1<\/a><\/sup>. It filed its full written response on July 22, 20261<\/a><\/sup>.<\/p>\n No Vietnamese producer, exporter or other foreign party filed a full response1<\/a><\/sup>. Commerce told the ITC about this on Aug. 24, 20261<\/a><\/sup>. Under U.S. trade rules, that silence allows the faster review1<\/a><\/sup>.<\/p>\n The petition that started the case in 2020 came from the American Copper Tube Coalition3<\/a><\/sup>. Its members then included companies of the Mueller Group and Cerro Flow Products, LLC3<\/a><\/sup>. The 2026 notice does not name the group that took part in the review.<\/p>\n The order covers seamless refined copper pipe and tube from Vietnam<\/strong>1<\/a><\/sup>. The full product description sits in Commerce’s decision memorandum, which is not attached to the notice1<\/a><\/sup>.<\/p>\nWhat did Commerce decide on Vietnamese copper pipe?<\/h2>\n
