Rescission of anti-dumping duty on maleic anhydride removes the prior levy while preserving earlier actions. The Central Government rescinds Notification No. 105/2008 imposing anti-dumping duty on maleic anhydride originating in or exported from specified foreign origins, acting under the Customs Tariff Act and applicable anti-dumping rules, with a savings clause preserving actions or omissions effected before the rescission.
