(VOVworld) - The US Department of Commerce (DOC) has announced its preliminary determination to adjust tariffs on Vietnamese frozen tra (Pangasius) fillets imported into the US. According to the US-based Vietnam Trade Office (VTO), the DOC decided to impose import tariffs from zero to 2.39 USD per kilogram on Vietnamese Pangasius fillets in the 10th administrative review (POR 10) from August 2012 to July 2013. Following the DOC’s preliminary decision, Vinh Hoan JSC was taken off the list of suppliers subject to investigation, enjoying a zero tax rate, while tariffs for the Hung Vuong Group and 23 other companies were revised to drop from 1.2 USD to 0.58 USD per kilogram. AnviFish was subject to the highest rate at 2.39 USD per kilogram as it did not supply specific timely information to the DOC. The VTO said the Vinh Hoan case is a big success as it is the leading Pangasius exporter to the US. However, it claimed the tariffs are unreasonable as the DOC used Indonesia as a reference country to calculate the dumping margin. The new tariffs won’t come into effect until the final determination is issued. The relevant parties will have 120 days to consider the decision.
