Tax option for disposal of mutilated petroleum goods allows payment at a prescribed GST rate when certified non serviceable. The notification inserts petroleum operations and coal bed methane operations under specified hydrocarbon licensing contracts into the covered activities, and adds a proviso allowing the recipient or transferee, at their option, to pay tax at the prescribed rate on transaction value where goods are disposed of in non serviceable form after mutilation, provided they produce a certificate from a duly authorised hydrocarbon officer confirming the goods are non serviceable and mutilated.
