New Trade Case on Imports of Seamless Refined Copper Pipe and Tube from Vietnam

July 2, 2020

A new U.S. antidumping (“AD”) petition was filed on June 30, 2020, by the American Copper Tube Coalition (“Coalition”) against imports of seamless refined copper pipe and tube from Vietnam.

The merchandise covered by this Petition includes seamless refined copper pipe and tube (“SRC tube”). SRC tubes are generally used for fluids under pressure, either for conveyance or in a closed loop for thermal transfer. Conveyance applications include household, commercial, institutional, industrial, and municipal water applications, as well as distribution systems for other liquids and gases. Thermal transfer applications for SRC tube include household, commercial, institutional, and industrial heating systems, commercial refrigeration systems (such as grocery store refrigerated cases) and combined or split-unit air conditioning systems of all sizes. This merchandise is identical to the merchandise currently subject to antidumping duty orders on imports from China and Mexico. Please see the scope section below for a full review of the subject merchandise.

The petition includes an AD (less than fair value) allegation against Vietnam. The Department of Commerce (“DOC”) and the International Trade Commission (“ITC”) will conduct the investigation. Within the next 45 days, the ITC will determine if there is a reasonable indication that the imports are injuring the U.S. industry. If the ITC finds that standard is met, then the cases will move to the DOC which will calculate the preliminary AD duty margin.

The DOC’s preliminary determination is currently scheduled for December 7, 2020, which is the date when importers will be required to deposit the calculated duties upon the products’ entry in the U.S. market.

There are strict statutory deadlines associated with these proceedings and affected companies are advised to prepare as soon as possible. If this product is of interest to you, please let us know so that we can provide you with additional information as it becomes available.
