Service tax refund against export

Apply for some services on Form ST-1 and get yourself registered and then start claiming refund and every half year you file nil returns if your firm does not pay any reverse charge for any of the services 

Sivaram, Many thanks for your reply.

As per your suggestions, we will apply on form ST-1. Will it be suffice if we register for 4 following services ?:

-Transport of goods by rail...

-Clearing and forwarding agent

-Customs house agent service

-Cargo handling service.

We will opt for electronic refund of ST at customs against each and every shipping bill to be filed. 

Secondly, we wish to avail service tax exemption as per notification # 31/2012. Can we avail this also, besides above, by filing EXP1 and EXP2 ?

Thanks in advance !
