The state-run agency would seek 15,000 tonnes of non-glutinous brown rice and 15,000 tonnes of short non-glutinous brown rice, an official at the agency said.
It will be the third tender for imported rice this year. In the previous two tenders, South Korea sought a total of 45,165 tonnes of rice.
South Korea has to import 225,575 tonnes of rice to meet its 2005 import quota.
