The tenders for red milling wheat close on Sept. 3, they said.
A total of 25 separate tenders each seeking 10,000 tonnes of wheat have been issued by the TMO, the traders said.
The TMO reserves the right to buy up to 20% more or less than the tender at its own discretion, they said.
The wheat is sought for shipment between Sept. 10-27.
Offers can be made in U.S. dollars, Russian roubles or Turkish lira. Accepting rouble offers is aimed at increasing participation by Russian exporters.
