AQS and E Weights Explained

Here’s a quick break down of how it works:

• Manufacturers can fill packages with an average amount, rather than having to ensure every single package meets a minimum weight (like under the minimum weight system).
• This reduces waste for manufacturers.
• There are still measurement rules to make sure consumers get what they pay for:
  • The average amount in a batch of packages must be equal to or greater than the amount stated on the label (this is defined as ‘nominal quantity’).
  • A small number of packages can have slightly less than the labelled amount, but not more than a certain limit (defined as ‘tolerable deficiency’)
  • No package can have less than the labelled amount (twice the prescribed tolerable deficiency).

For manufacturers, migrating to AQS packaging in Australia involves a few key steps:

1. Understanding the Regulations: Familiarise yourself with the specific AQS regulations set by the NMI (Weights & Measures). You can find details on their website “https://www.industry.gov.au/publications/guide-average-quantity-system-australia” or by searching for “NMI AQS”.
2. Equipment and Process Review: Evaluate your current packaging equipment and processes. AQS requires accurate filling and reliable measurement systems. You might need to invest in upgrades or new equipment to ensure consistent average weight across packages.
3. Sampling and Testing Procedures: Develop a sampling and testing plan to monitor your AQS compliance. This involves regularly taking samples of filled packages and statistically analysing the average weight against the declared amount.  The most effective/efficient way to do this is to get an AQS compatible inline checkweigher.
4. Labelling Updates: Update your packaging labels to reflect the AQS system. Labels should clearly state the average amount of the product, following the NMI guidelines.  This basically involves adding an “e” (stands for “estimated”) symbol next to the net weight value.
5. Record Keeping: Use checkweigher systems to monitor the average net content of all packs inspected. Maintain detailed records of your AQS compliance checks and sampling data. This demonstrates your adherence to regulations during potential audits by NMI inspectors.  Most modern inline checkweighers can collect and report on 100% of your weight data and create the required batch reports.
