Manpower supply will applicable when the employees are working under other company and u have taken use of them , and done a contract with that company for supply of man power for your work... they are not your employee

in this case that person is your employee now...

No...

It will not applicable,,,

No. In this case the other company is only providing you recruitment consultancy service (a type of consultancy service). simply put the other company is a recruitment agency which suggests to you the candidates, you interview them and decide if you want to employee them. 

Whereas a manpower supply would involve a contract with the other party to supply you with workers employeed by the other party. The manpower in this case is not your employee and the party supplying manpower is a contractor.
