Rescission of customs notification withdraws prior exemption while preserving prior actions and omissions. The Central Government, invoking sub-section (2) of section 9A of the Customs Tariff Act, 1975 read with rule 13 of the Anti-dumping Rules, rescinds notification No. 5/2005-Customs (published as G.S.R.42(E)), withdrawing its effect prospectively while preserving actions done or omitted before the rescission.
