The businesses are also permitted to buy a similar amount of rice from Thailand and 50,000 tonnes from China, India, Pakistan and other countries, with a total volume of 805,200 tonnes.
The time for delivery is set before February 28, 2017.
VFA Chairman Huynh The Nang said that this was a chance for Vietnamese businesses to boost rice consumption, which is low now.
In late August 2016, Vietnam won a bid to provide 150,000 tonnes of rice to the Philippines at the price of US$424.85 per tonne.
