Service tax query

I am working in a Packer & Movers Company and we provide the relocation services to our client.

I have a query regarding the levy of Service Tax on our services.

Suppose we have to shift the client;s household items to Singapore. Now after packing & loading the goods on the port,

goods are sent to Singapore port and there we take the services of agent to move the goods from Singapore port to its final destination, i.e. at client home situated in Singapore.

For this services provided by agent to us, he raises bill on us and we do payment.

Now my query is this, whether this payment made by us to our foreign agent is exempt from Service Tax???

As there is a Notification No-8/2011 of ST which exempt this services from the levy of ST.

Kindly solve my query and obliged.  

Thanks & Regards...
