Market disruption investigations begin only on sufficient evidence of increased imports, injury, and causation, whether by application or suo motu.

Initiation of investigation requires sufficient evidence that increased imports have caused market disruption or a threat of market disruption to the domestic industry. The Director General may act on a written application by or on behalf of a domestic producer of a like or directly competitive article, provided the application is in the prescribed form and supported by evidence of increased imports, injury, and causation. Investigation may also begin suo motu on information from customs authorities or other sources if those same evidentiary requirements are satisfied.
