No purchase has yet been made and results are expected later on Wednesday, they said.
The lowest offer was made for 25,000 tonnes.
This was followed by soft wheat offers for other shipment positions in the tender at $200.10 and $199.23 a tonne c&f, they said.
Lowest offers in the tender for 50,000 tonnes of animal feed barley were $192.68 and $194.69 a tonne c&f also for different shipment positions.
The Tunisian agency does not always purchase the lowest offer if other conditions connected with the offer are seen as unattractive.
