Anti-dumping duty on non-cooperating exporter leads to definitive levy on certain polyester yarn imports from a retrospective effective date. The Central Government amends Notification No.15/2007 to omit S. No.5 in Table I and inserts a paragraph that the anti-dumping duty on specified polyester yarns produced and exported by M/s H.K. Corporation, treated as a non-cooperating exporter for violating a price undertaking, shall be levied with effect from the 15th November, 2007, implementing the definitive duty recommended by the designated authority.
