On 20 June 2014, the International Trade Administration Commission (ITAC) initiated an investigation into the alleged dumping of wheelbarrows from China. The application was lodged by Lasher Tools. In  their application, Lasher calculated the dumping margin to be 505.33%. “It is unusual for a cooperating manufacturer, in this case Qingdao Youhe, to receive a preliminary (or final) anti-dumping duty that is more than the residual duty.” The residual duty is calculated for the rest of the manufacturers that did not submit their information to ITAC, that is, the manufacturers that did not corporate with ITAC in the case.  The preliminary duties will be in place until 4 September 2015. ITAC must institute final duties on or before this date otherwise the preliminary duties will lapse and importers that have been paying these duties will be able to claim them back from Customs.
