After a case is initiated, MOFTEC, together with the General Customs Bureau, will investigate the existence of dumping and a dumping margin. The SETC, together with relevant industry authorities, will investigate in the existence of injury and injury level. The investigation will usually take 12 months, or under special circumstances, 18 months before final determinations are given. During the period, the two authorities may give preliminary determinations no earlier than 2 months after the date of initiation, resulting either in provisional remedies or cancellation of investigations. Both authorities as required by interested parties may hold evidentiary hearings.
