DairyAmerica, a marketing company for four US dairy cooperatives, will begin selling milk products through Fonterra's GlobalDairyTrade platform in October, as the auction site opens to outside participants.
Starting on October 4, DairyAmerica will offer skim milk powder through the platform with the intention of adding more products over time, GDT said in a statement.
More outside suppliers may follow, as Fonterra has held talks with Europe's Arla Foods and FrieslandCampina, and Australia's Murray Goulburn. GDT, which began in 2008, published market rules last week.
DairyAmerica's producers account for about 45 per cent of the non-fat and skim milk powder produced in the US The marketing company exports about 176,000 metric tonnes of products a year. Some 650,000 tonnes of Fonterra dairy products trade on the GDT site each year.
"Looking forward, the company would be managing a significant proportion of its export business through GlobalDairyTrade, rather than through distributor and reseller arrangements," DairyAmerica chief executive Rich Lewis said.
