Public notice requirement ensures detailed disclosure and timelines when investigating injury from tariff-driven import increases. Initiation requires a public notice specifying the originating good, investigation period, initiation date, summary of alleged serious injury, reasons, contact address, and submission time-limits; copies of the notice and application are forwarded to central ministries, known exporters or trade associations, the foreign government, and other interested parties. The Director General may call for written information from exporters, foreign producers and the foreign government within thirty days or an extended period, treat dispatched documents as received one week after sending, invite industrial users and consumer organisations to submit relevant information, allow oral presentations only if subsequently filed in writing, share evidence among parties, and rely on facts available where parties fail to cooperate.
