The new marketing alliance will focus on the bulk export of durum from Australia and will commence immediately.

CHS is a leading global durum marketer, with strong linkages to millers and more than half a century of durum milling expertise.

Graincorp says the alliance will integrate the Australian durum industry into the global durum supply chain.

It says the global reach of CHS will provide access to a range of new markets and is a strong signal to Australian durum growers that should encourage the growth of this niche, high-value segment.

"The marketing alliance with CHS Inc is an important one for GrainCorp and the Australian durum industry," GrainCorp managing director Mark Irwin said.

"GrainCorp brings the strength of our wheat desk, our upcountry grain accumulation and storage expertise, our road and rail logistics and port infrastructure to this alliance.

"CHS Inc bring their expertise as a leading durum marketer and processor, and the strong relationships they have with the world’s leading durum processors."

In return CHS senior vice president Rick Browne said the partnership with GrainCorp would allow CHS to create more value for its durum customers by providing them access to Australian durum in addition to North American and Mexican durum.
