Viterra’s harvest receival standards reflect industry codes of practice and are based on the industry standards set by Grain Trade Australia (GTA), the Australian Oilseeds Federation (AOF) and Pulse Australia.

Industry conducts annual reviews of these standards and implements changes where appropriate to meet demands from end-use markets. 

The following changes have been made for 2018/19

  • Snail tolerances in barley have changed to one snail per half litre for malt and F1 grades (down from two snails last year). There is no change for F2 snail tolerances.
  • The tolerance for sand/soil in canola has changed to 0.1% by weight per half litre (up from 0.06%).
  • Parthenium weed has been changed to a nil tolerance for all commodities as it is declared a weed of national significance. Refer to the Department of Primary Industries and Regions South Australia for more information,
  • Saffron thistle in canola has been changed to a Type 2 weed seed with a tolerance of one per half litre (previously a Type 1 weed seed with nil tolerance).
  • Compass and Spartacus barley varieties have been accredited by Barley Australia for malt. Viterra receival standards are as per GTA malting barley.
  • Viterra is offering dynamic binning tolerances for wheat in 2018/19.

Viterra continues to offer growers a higher moisture standard for wheat and barley to 13.5%, which is above the GTA standard of 12.5%.

All Viterra receival standards and grade segregations can be found on this website.

From time to time, Viterra will offer additional grade segregations that reflect particular customer specifications and may be for specific sites only.

Declarations on glyphosate and genetically modified commodities

International end-use customers and markets are increasingly requesting glyphosate-free grain and declarations regarding genetically modified varieties. To continue to meet these needs, Viterra will ask all growers to declare this information for all commodities. The Delivery Advice and Declaration Book has been updated for 2018/19 to accommodate this change.

  • Malting barley
    Glyphosate is not permitted on malting barley. If a grower’s malt barley has glyphosate applied, the highest grade achievable is feed barley.

  • Durum wheat
    Durum with glyphosate applied will be accepted this harvest. The new version of the Delivery Advice and Declaration Book is required for all durum deliveries to collect glyphosate information. From 2019/20, Viterra will only receive glyphosate free durum in order to meet end-use needs and maintain market access.

Lentil cleaning grade

A cleaning grade will continue to replace the Number 2 grade for lentils, providing greater flexibility for growers delivering into Viterra sites for the 2018/19 harvest.

The cleaning grade allows an increase in the maximum for total defective material to 11% and a higher tolerance for foreign seed contaminants.

Tonnage deduction will be applied on a sliding scale, outlined in the flyer below.


Canola declaration

For each load of canola, growers will be required to declare on the Delivery Advice and Declaration Form, that none of the canola in the load is a genetically modified variety.

As South Australia has a moratorium on GM canola, Viterra only offers non-GM segregations and can only accept varieties of canola from the Australian Oilseeds Federation (AOF) approved list for non-GM varieties.

As part of the quality testing program, Viterra collects samples from all grower loads of canola delivered to site for GM and chemical residue testing. This is essential to ensure that canola quality meets the expectations of customers as well as state and federal legislation.

Varietal identification program

Each variety has different physical qualities, processing performance and end-product quality for customers and end-users.

Viterra participates in varietal identification programs where grower load samples will be randomly selected at sites across the Viterra network and tested to ensure varietal declarations have been correctly recorded.

This information is forwarded to relevant industry research groups and is used to establish appropriate codes of practice for the delivery of grain.

Chemical residue testing

Viterra subscribes to the National Residue Survey (NRS) – a crucial part of the Australian system for managing risks of chemical residues in Australian food products.

To support this program, during harvest Viterra conducts chemical residue testing on composite partition samples. Viterra may also collect individual grower load samples for chemical residue traceability.

Growers play a critical role in upholding South Australia’s grain quality. When applying chemicals, at all times growers should adhere to:

  • withholding periods
  • label instructions
  • application rates
  • safe operating procedures

If a breach to the Australian maximum residue limit (MRL) is detected, Viterra is obliged to provide its traceability results to Biosecurity South Australia which may trigger an investigation. Any breaches to Australian MRLs may also be followed up through Viterra’s contaminated grain process.

Information on the current Australian and international MRLs can be found on the Department of Agriculture and Water Resource’s website

Commodity Classification Transfer Procedure

The Commodity Classification Transfer Procedure allows for a load classified at one site to be received at a second site while retaining its original classification (subject to nil tolerance contaminants or defects).

This transfer procedure applies when a commodity is presented to a site but the load is classified as a grade not being received at the site. A transfer can then be requested to deliver the load to an alternate site accepting that grade.

The grade on the commodity classification transfer will be in line with receival standards not accounting for the wheat dynamic binning tolerances. However, the load will be eligible for wheat dynamic binning at the transfer receival site provided the higher grade segregation is available, and the rolling stack average of the higher grade meets the receival standards.

Growers can utilise the commodity classification transfer procedure for port terminal deliveries where shipping grades are being accepted from upcountry sites. This will ensure that the load is within specification and will not be declined at port due to the lower grade not being accepted.

Loads being transferred do not have priority over other loads in the sampling queue.

If a nil tolerance contaminant or defect is found in the load at any stage of the receival process, the load will be declined.

Classification Dispute Resolution Procedure

The Classification Dispute Resolution Procedure is used when a grower (or their representative) disputes the classification of their load at the point of receival.

The classification dispute resolution procedure has been updated to be in line with the GTA technical guideline. This includes the quality parameters that can be disputed, the sample to be assessed and the allowable variation of the initial result from the standards limit.

Shot or Sprouted Grain Classification Procedure

The Shot or Sprouted Grain Classification Procedure is to be used if the classifier finds one shot barley kernel or one sprouted wheat kernel. The load will then be assessed using a Falling Number or Rapid Visco Analyser (RVA) machine and the result used to determine the grade.

Falling Number and RVA partition results are also monitored throughout harvest and could lead to testing each load regardless of visual assessment.
