Tax deductions incase of purchases made from outside India

Members,

I would like to know whether TDS is applicable for Imports made from outside India, i.e.while making payment against the purchase made from outside India whether TDS is deductible. Is there any other deduction which need to be made by the Indian party before making payment to the other party outside India, if yes which ?  

looking for a promt reply

kind rgds
