Anti-dumping duty continuation on acetone maintained, extending import control measures for a further specified review period. The Central Government, invoking the powers under sub-sections (1) and (5) of Section 9A of the Customs Tariff Act and rule 23 of the relevant rules, amends the earlier notification imposing anti-dumping duty on imports of acetone so that 'Notwithstanding anything contained herein above, this notification shall remain in force up to and inclusive of the 18th day of June, 2013, unless revoked earlier'.
