gst rcm on freight paid for goods purchased

I have to pay freight on goods purchased to transporter. In single instance the amount of freight is about 500 to 1000 Rs.

My question is whether I am liable to pay GST under RCM ? Even though my total daily payment remains below Rs. 5000

Experts please help, because some opinion says that freight paid does not come in calculation of daily 5000 limit, so GST on freight is payable under RCM, even if amount of freight is Rs. 100.

Thanks
