Anti-dumping duty extension on Phthalic Anhydride to continue until specified expiry under Customs Tariff Act. Extension of anti-dumping duty on Phthalic Anhydride from Korea RP, Chinese Taipei and Israel is effected by amending Notification No. 58/2012-Customs (ADD). Following a subsection (5) review under section 9A and rule 23, the Central Government inserted a paragraph providing that the notification shall remain in force up to and inclusive of a specified expiry date, unless revoked earlier, thereby continuing the anti-dumping duty regime in accordance with statutory review and extension procedures.
