A Tunisian state agency has issued an international tender to purchase up to 27,000 tonnes of vegetable oils, European traders said on Thursday. Either crude degummed soyoil or crude degummed rapeseed oil is sought. The tender closes on Friday, April 30. The oils can be sourced from optional origins. Delivery is sought in three 9,000 tonne consignments between May 20 and July 4. Rapeseed oil is only likely to be purchased if offered more cheaply than soyoil, traders said.
