As part of our ongoing focus of providing a valuable and efficient service to growers, Viterra is continuing to provide dynamic binning for the 2020/21 harvest giving growers the opportunity to have their wheat and barley instantly upgraded.

Dynamic binning is available for wheat grades ASW1, APW1, H2 and H1, and barley Malt1 grades for Planet, Scope, Spartacus and Compass as well as BAR1 (previously F1).

Dynamic binning delivered approximately $4.7 million in value during the 2019/20 harvest to growers who were able to access higher grades, including $2 million for barley upgrades. Of the deliveries in the tolerance zone, 97% of barley and 90% of wheat were upgraded. It also created efficiencies in the classification process due to less retests being required.

Dynamic binning provides growers with more flexibility to potentially access a higher grade for loads that are just outside of receival standards.

In addition to dynamic binning, we also provide a 1% tolerance for moisture above Grain Trade Australia (GTA) receival standards on all wheat and barley deliveries, which has been in place for a number of years.

To receive a dynamic binning upgrade, the following four criteria need to be met:


Dynamic binning is available at all Viterra sites with segregations for wheat grades ASW1, APW1, H2 or H1 and barley grade BAR1 (F1) and Malt1 grades for Planet, Scope, Spartacus and Compass.

Growers will have the opportunity to have their wheat and barley upgraded for loads that are just outside of the receival standards.


Viterra’s dynamic binning is instant – the grade is printed on the ticket at site and is immediately available to transact.

Through dynamic binning, we are able to provide more value to growers, and at the same time continue to meet customers’ outturn requirements.

If the rolling stack average falls below the GTA receival standards for protein, screenings or test weight, then dynamic binning will not be available.

At all times we need to make sure the stack is running within the GTA standard to ensure outturning is not compromised.


Rolling stack averages are calculated on live running samples.

Every time a load goes in, the stack average adjusts.

The rolling stack averages are worked out differently for each type of storage. Smaller storages use less tonnes in the rolling stack average.

Viterra made a significant upgrade to its IT grain management system in 2018, which enables the quality of grain to be monitored closely in real time to ensure it meets outturn standards.

Through dynamic binning, we’ve been able to provide a valuable service to growers while also maintaining market access for South Australian grain and continuing to meet the high standards of end use customer requirements.
