Regulation of commodity derivatives: government may exempt or extend securities law to specific delivery contracts by notification. Section 30A distinguishes non-transferable and transferable specific delivery contracts for commodity derivatives, excluding non-transferable contracts from the Act while prohibiting organisation of associations that enable performance without actual delivery in areas where section 13 applies; the Central Government may, by notification, exempt transferable contracts in specified areas or, in the public or trade interest, bring specified non-transferable contracts within the Act and prescribe the manner and extent of application.
