New Trade Case on Imports of Aluminum Wire and Cable from China

September 24, 2018

New US antidumping (AD) and countervailing (CVD) duty investigations were filed on September 21, 2018 by Encore Wire Corporation and Southwire Company (petitioners) against imports of aluminum wire and cable from China.

The merchandise covered by the petition includes certain aluminum wire and cable that is generally used for electrical power in residential, industrial, and commercial applications. The full scope of the merchandise covered is set forth below.

The petition includes AD (less than fair value) allegations against China and CVD (unfair subsidy) allegations against China.

The Department of Commerce and the International Trade Commission (ITC) will next determine whether to launch AD and/or CVD duty and injury investigations, respectively, on these products. Commerce will be responsible for calculating the ultimate AD/CVD margins on the imports, while the ITC will conduct a concurrent investigation to determine if the imports are injuring the U.S. industry. If Commerce finds dumping or unfair subsidization in its preliminary determinations, currently scheduled for December 15, 2018 (CVD) and February 28, 2019 (AD), importers will be charged 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.

The scope of the investigations is aluminum wire and cable (“AWC”), which is defined as an assembly of one or more electrical conductors made from 8000 Series Aluminum Alloys, Aluminum Alloy 1350, and/or Aluminum Alloy 6201, provided that: (1) at least one of the electrical conductors is insulated; (2) each insulated electrical conductor has a voltage rating greater than 80 volts and not exceeding 1000 volts; and (3) at least one electrical conductor is stranded and has a size not less than 16.5 kcmil and not greater than 1000 kcmil. 

8000 Series Aluminum Alloys is defined in accordance with American Society for Testing and Materials (“ASTM”) B800.  Aluminum Alloy 1350 is defined in accordance with ASTM B230/B230M or B609/B609M. Aluminum Alloy 6201 is defined in accordance with ASTM B398/B398M.

The assembly may or may not: (1) include a grounding or neutral conductor; (2) be clad with aluminum, steel, or other base metal; or (3) include a steel support center wire, one or more connectors, a tape shield, a jacket or other covering, and/or filler materials.
