RCM on Freight Charges paid on Organic Manure

This discussion seeks clarification on whether Reverse Charge Mechanism (RCM) applies to freight charges for transporting organic manure when the manure itself is subject to a 5% GST. While the transportation of organic manure by a Goods Transport Agency is generally exempted under Notification No. 12/2017 of the CGST Act, there's uncertainty about this exemption applying to taxable supplies under RCM. The user's CA has denied the transportation exemption in this specific scenario.
