Accordingly, the DOC will impose a common tariff of 111.47% on Vietnamese OCTG exporters while only one business working hand in hand with the DOC during the investigation process is subject to duty of zero percent as it did not dump prices on the US market.Judging from the initial duties as announced on July 11, 2014, it is considered a success of a Vietnam business. The DOC creates the possible conditions for relevant sides to send case briefs within 30 days since it publishes a notice in the Federal Register and rebuttal within five days since the submitted day.  Besides, if relevant sides request a hearing, they must send their official requirement to the Assistant Secretary for Commerce within 30 days since the notice is published.The DOC will issue its final decision on the review within 120 days since the preliminary decision is announced in the Federal Register.In 2014, the Canada Border Services Agency initiated anti-dumping and anti-subsidy investigations on Vietnam OCTG products and imposed AD duties of 28.6%.
