Receival standards

How receival standards are set

Each year GIWA collaborates with Western Australian bulk handlers, including CBH, to review receival standards. The organisation implements changes on an as-needs basis to ensure that grain meets customer requirements, and grower returns are maximised. This alignment takes place through consultation with growers and marketers through the GIWA Receival Standard Committees.

Refer to the GIWA website for more information on how standards are set.

Moisture management

For the 2025/26 harvest, high moisture grain will be managed as follows:

• There are no dedicated high moisture segregations for feed barley and wheat.
• High moisture barley can be received into feed barley grades.
• High moisture wheat can be received into the grades AWW1 and AWW2.
• There are no high moisture charges.

The receival standard base limits for moisture are:

• Milling wheat grades up to 12.5%
• AWW1 and AWW2 wheat up to 13.5%
• Malt grade barley up to 12.5%
• Feed grade barley up to 13.5%.

For milling grades of wheat, AWW1 and AWW2 wheat, and all feed barley grades only, grain with higher moisture may be received provided the site stack weighted average is within parameter. These higher limits will open and close on notice.

• For milling grades of wheat, grain will be received up to 13.5% moisture dependent on the stack weighted average. 
• For AWW1 and AWW2 wheat, grain will be received up to 14.0% moisture dependent on the stack weighted average
• For all feed barley grades, grain will be received up to 14.0% moisture dependent on the stack weighted average. 

Sprouted grain and falling numbers

Sprouted grain severely degrades the quality of grain so any load containing sprouted grain is considered feed grade, according to the Wheat Receival Standards.

We may use several options at each receival point to manage sprouted grain, including:

• Visible detection of sprouted grains/sprouted count assessment
• Stack monitoring
• Load-by-load Falling Number assessments

A Falling Number assessment overrides the sprouted count assessment and may allow the load to achieve a higher grade. For us to assist you in achieving maximum value for wheat deliveries, Falling Numbers will be used to manage stacks and grower loads. This will ensure each delivered load can achieve the highest grade possible, while ensuring individual segregations remain within market specification.

CBH has the right to grade any load of wheat by Falling Number assessment, whether sprouted grain has been detected visibly or not. Please contact your local CBH office if you have questions regarding Falling Number assessments.
