Credit of the tax paid on any service can be availed if it falls within scope of the term "input service" as defined under Cenvat Credit Rules, 2004.
Inward transportation of inputs has been specifically been included in the definition.
"Activities related to business" is another item that is included in the definition of the term 'input service'. As could be noted the phrase is of very wide import and the inward or outward transport of inputs, finished goods, capital goods, rejected materials or any thing related to business would get covered.
input credit on service tax paid ( either charged by GTA or paid by receipent)on transport charges for inward entry is available, as it qualifies under "input services"
