Excise and export

Hi ..

We are merchant exporter of ready made garments from Mumbai and export branded shirts to our overseas client . The manufacturer of shirts  , from whom we buy garments , fall under excise liability as per their yearly turn over and they are registered with Excise Dept after the change in policy in the budget of Feb 2011.

What are the formalities we have to folllow when we wish to purchase goods from this company and export to our overseas client ?? Some one informed us that we have to fill up form CT 1 with bond ...so does this bond involves actual advance remittance to excise dept ?? What deductions they show in this bond ??
