U.S. Department of Commerce Confirms that Door Thresholds are Covered by the Scope of the AD/CVD Orders on Aluminum Extrusions from China

January 22, 2019; Wauconda, Illinois -- On December 19, 2018, the U.S. Department of Commerce (“Commerce Department”) issued final decisions in three scope proceedings, confirming that door thresholds are covered by the scope of the AD/CVD orders on aluminum extrusions from China, pursuant to requests for scope rulings from Columbia Aluminum Products, LLC, Worldwide Door Components, Inc., and MJB Wood Group, Inc.

The Aluminum Extruders Council (AEC) and Endura Products Inc. had participated jointly in these proceedings and provided the Commerce Department with critical information demonstrating that door thresholds containing extruded aluminum are plainly covered by the scope of the AD/CVD orders and were intentionally included within the scope by the petitioner during the original investigations.

The Commerce Department agreed and confirmed the express inclusion of the extrusion in the door thresholds to be within the scope of the AD/CVD orders and explained that for this reason, door thresholds cannot be removed from the coverage of the AD/CVD orders pursuant to a claim that these products are finished merchandise.

“This is a clear win for the aluminum extrusion industry in the United States,” said Jeff Henderson, President of the AEC.  “The trade orders, which have been in effect since April 2011, clearly state door thresholds were covered by our orders.  It was very important to the AEC and its members that Commerce stand by its orders and declare these extrusions subject to the duties,” he continued.

“We applaud the Commerce Department’s decision, which is an important step forward in addressing the evasive practices that we have seen from various Chinese extruders,” said Robert DeFrancesco, counsel to the AEC and Endura Products.  “This ruling is critical for ensuring that the AD/CVD orders are effectively enforced so that American jobs are not harmed from unfair trade.  We urge the Commerce Department and U.S. Customs and Border Protection to continue to take all necessary measures to ensure that the AD/CVD orders on aluminum extrusions are being fully enforced.”

The AEC has led the U.S. aluminum extrusion industry in achieving level competition by winning tariff protection that offsets unfair trade practices of extruders/importers of aluminum profiles produced in China. The efforts have been of enormous value to domestic extruders and suppliers. They may have saved the industry. Conservatively, AEC estimates 800 million pounds per year of extrusions are being produced in the U.S. that would have otherwise been lost to China. For more information, visit

The Aluminum Extruders Council (AEC), established in 1950, is an international association dedicated to advancing the effective use of aluminum extrusion in North America. AEC is committed to bringing comprehensive information about extrusion's characteristics, applications, environmental benefits, design and technology to users, product designers, engineers and the academic community. Further, AEC is focused on enhancing the ability of its members to meet the emerging demands of the market through sharing knowledge and best practices. Advocacy programs ensure that aluminum extruders, suppliers and their products remain relevant and viable in an ever-changing legislative and regulatory climate. More than 120 member companies represent primary aluminum producers and other industry suppliers in addition to aluminum extruders operating hundreds of extrusion presses in hundreds of plants worldwide.
