Tds on transportation charges

Below mentioned question is for A.Y. 2011-12 relevant to F.Y. 2010-11

One of my client is trading in Wheat products. He sales goods on FOR basis i.e. goods will be delivered to the godown of buyer and charges are all inclusive.

Now the buyer pays transportation chares directly to transporter and debits the account of seller.

Wheteher the seller incurs any liability to deduct TDS on amount paid directly by the buyer?
