According to the final results of the expedited first sunset reviews of the antidumping duty orders, the US Department of Commerce (USDOC) concluded that revoking the antidumping duty (AD) orders on large-diameter welded pipe from China, India, Canada, Greece, South Korea, and Turkey would likely result in the continuation or recurrence of dumping.

Commerce determines that revocation of these orders would likely lead to dumping with weighted-average margins of up to: 132.63% for China; 50.55% for India; 12.32% for Canada; 10.26% for Greece; 20.39% for South Korea; and 2.57% for Turkey.
