1. No deduction is to be made for sum credited/paid to a contractor during the course of business of plying/hiring/leasing of good/carriages on furnishing Pan to the payer/ deductor . So, if you are paying a person for plying/hiring/leasing of good/carriages, he is a transporter.
2. If the manufacturer is providing transport service to you, he also will be a transporter (as he is raising a seperate bill). You need not deduct tax if he furnished PAN to you. However this has to be disclosed in TDS return.
