Deliver grain post-harvest

A late grain receival service is available for grain received after 1 March each season. Following these procedures will enable fast and efficient access to the CBH system outside of the normal harvest period.

If you are still harvesting and delivering to sites which remain open for grower receivals, these guidelines will not apply. These guidelines apply for all grain deliveries until the new crop receival season.


If you are intending to make a late delivery to CBH you will need to call the local area contact, Port or Metro Grain Centre to advise of your intended delivery details, including commodity and approximate tonnes for delivery.

There are three options to deliver grain:

  • No declaration of chemical application - post-harvest

    Where grain has not been treated with chemicals post-harvest, loads will be sampled and graded using normal grain receival standards and procedures. A CDF will need to be provided with the load. Closer scrutiny of contaminants and live insects will occur which may require additional spears per load. If the load is found to be contaminated or under-grade, the load will be rejected and there will be no re-tendering of the load permitted.

  • Declaration of phosphine treatment

    Where the grain has been treated with phosphine, a pre-delivery sample is not required. However, you will be required to inform staff of the phosphine treatment on site before the load is tendered for delivery to CBH.

    The load will be tested for the presence of phosphine prior to being sampled. Where phosphine is detected, the load will be considered as contaminated and will not be deliverable to CBH. Re-tendering of the load will not be permitted. If no phosphine is detected, the load will be sampled and graded using normal grain receival standards and procedures.

  • Declaration of chemical application - post-harvest

    Where chemicals have been applied to the grain post-harvest (excluding phosphine), you will need to provide a pre-delivery sample to CBH for testing prior to delivery.

    1. Collect a 1kg representative sample from each on-farm storage that grain will be delivered from. If the grain is from more than one storage, clearly mark the storage ID on each sample.
    2. Complete a Pre-Delivery Sample Analysis form, sign and attach it to the sample. Pay attention to providing the intended delivery details, approximate tonnes for delivery and the treatment details section of the form.
    3. Deliver the sample to the local CBH office or direct to:
      Australian Grain Centre
      Pre-delivery Sample
      700 Abernethy Road

Sample Results

All samples are tested at the Australian Grain Centre (AGC) in Perth. You will be contacted with the sample results within three (3) business days of receipt of the sample at the AGC.

Sample Equipment

CBH can loan you equipment to collect your sample. You can request and collect equipment from your local CBH office.


Please contact the local CBH office or MGC to confirm site operating hours. All loads must have a completed CDF provided on delivery.

A sample will be taken from each load delivered to test for chemical residues that cannot be assessed at the point of delivery.

If the sample results are positive for chemical residues (Level One contaminant), further deliveries will be halted and the contaminated loads process will apply. You may also be liable for contaminated load delivery charges and/or financial penalties. At any time CBH may request a pre-delivery sample if it deems chemical application has contaminated the grain.

Remote sampling and certified loads may be available if approved by the Area Manager.


Under Harvest Mass Management Scheme rules, deliveries from 1 March each year DO NOT receive any tolerance above their safe legal limits. AMMS can be used by relevant permit holders.

There will be no Active Stack Management or Extended Standard Tolerances available to late deliveries.

There will be no moisture management services available to late deliveries.

There will be no Quality Optimisation available for late deliveries.


Charges apply to all grain delivered from 1 March. See our Fees and Charges.
