Classification of Tramadol as a psychotropic substance: delayed applicability for licensed manufacturers, importers and exporters after grace period. The amendment defers the operational applicability of Tramadol's classification as a psychotropic substance so that licensed manufacturers, importers and exporters are subject to the notification only after the expiry of a prescribed grace period following publication; the earlier public notice is amended accordingly and Customs staff are to treat this Public Notice as a Standing Order.
