HAMBURG  - * Jordan's state grain buyer has issued another international tender to purchase 120,000 tonnes of animal feed barley to be sourced from optional origins, European traders said

* Tender deadline is June 26

* Jordan made no purchase in its previous tender to buy 120,000 tonnes of barley on Tuesday when only one trading house took part

* Jordan has struggled to purchase wheat and barley in tenders in past months after terms on specifications and payment were introduced which reduced tender participation by international trading houses

* Jordan also issued a separate tender for 120,000 tonnes of wheat on Thursday closing on June 27
