Dear Sir,
with reference to your reply it was clear by Notification under Central Tax Rate & under IGST Rate that credit is available to the recepient of service under RCM not in forward charge and as the Notification does not clarify like Service Tax is it available or not for outward transportation excluding FOR sale and Consignment sale cases like that yet.
Further, Secton 15(5)(b) which talks about credit is not available for following supply of goods and services or both...
"(i).............. except where an inward supply of goods or services or both of a particular category is used by a registered person for making an outward taxable supply of the same category of goods or services or both or as an element of a taxable composite or mixed supply"
As per this provision no where it allows ITC of GTA services used for outward supplies, but as still there is nothing has come out from ministry yet to understand that ITC of GTA is not available on outward supply, so may be manufacturer can claim.
If some other expert has some other expert views on the same kindly let me know.
