Circumvention of anti-dumping duty: authority may recommend extending duties to circumventing imports with retrospective effect. The designated authority may find circumvention and recommend imposition or extension of anti-dumping duty to imports, including those from origins not previously notified, with the levy potentially applying retrospectively from the date of initiation of the investigation. The authority must issue a public notice recording its findings, and the Central Government may implement the recommendation and extend the duty from the investigation initiation date or another date recommended by the authority.
