HAMBURG -

* Jordan's state grain buyer has issued another international tender to purchase 100,000 tonnes of animal feed barley to be sourced from optional origins, European traders said

* Tender deadline is March 21

* Jordan has had difficulty purchasing wheat and barley in tenders in past months after terms on quality control and payment were introduced which reduced tender participation by international trading houses

* Four previous tenders for 100,000 tonnes of barley ended without a purchase in February and March

* Jordan’s last reported barley purchase was 50,000 tonnes on Feb. 7

* The new tender seeks barley at the oldest from the 2016 crop for shipment in a range of combinations in 50,000 tonne consignments between Aug. 1 to Sept. 30
