Sir, I support the views of the experts above.
1) sir, Labour contract means supply of Labour to another to work under his control and supervision. It may be supplying Labour to manufacturer for using them in carrying out manufacturing activity. This would mean Labour contract I.e. supply of labour / ?manpower supply service .
2) Sir, pure Labour charges in carrying out civil work or erection of machinery or doing any Repair work would not qualify to mean works contract service. Works Contract would mean a contract for carrying out, say, construction work of building a wall which would involve both material and service or any work which involves both material and Labour.
Reverse charge is applicable on works contract service if in addition to above conditon the provider is an individual, HUF, Firm and receiver is the company. Valuation is also available. Thanks.
