Quality optimise your wheat

To be eligible for optimisation, wheat loads must:

• Have been grown in the current season
• Meet and satisfy the receival standards in the applicable shipping port zone
• Have a screenings result equal to or less than 10%
• Have a falling number equal to or greater than 300 seconds
• Have a moisture result equal to or less than 13% for Quality Optimisation into any grade
• Not have been optimised previously, whether in full or partially
• Not have been sold or transferred or outturned, whether in full or partially

To help CBH manage the risk of Quality Optimisation across the network, the following rules apply:

• All loads in a Lot must be from the same zone
• All loads in a Lot must be from one grower (deliverer) entity or share farm
• Loads must be optimised prior to the zone-based deadlines
• An optimisation cannot be reversed once any part of a load in an optimised Lot is sold or transferred
• All optimised loads will be physically transported through the CBH system
• An optimised load cannot be used as part of a Grower Outturn Request
• An optimised load cannot be sold using CBH Site Select.

Please read these documents for the full set of terms associated with Quality Optimisation.

To protect the outturn quality and integrity of your wheat internationally, the following limits will be applied:

• The highest grade on site at the time of delivery is the highest grade a load can achieve, if optimised. This is referred to as the ‘Service Cap’ in the Optimiser
• Mixed variety loads will default to the variety with the lowest class
• A load must be optimised within a class, except Hard varieties which can be optimised to APW.
• Grades can only be optimised where the load meets minimum protein: H2 min 10.5%, APW1 min 9.5%, ASW9 min 8.8% and ANW1 min 8.5% and max 12.5%
• An optimised Lot must meet the Optimised Lot Standards (max 3.5% screenings, min 76 hectolitre weight, max three distorted kernels, max moisture of 12.5% for milling grades/13.5% for AWW1 and AWW2) 
• Optimised Lots can be created with whole loads or part loads
• For grades H2, APW1 and ASW9, Optimised Lot Standards for protein are min. 11.7% (H2), min. 10.7% (APW1) and min. 9.2% (ASW9)
• H1, APWN, APW2 and AUH2 are not achievable via optimisation, which means you can only optimise out of these grades and not into them
• The maximum number of splits allowable per grower is one third of loads delivered
• The trial grades AWW1 and AWW2 are eligible for QO
