Understanding AQS & e-Weight Regulations

​An Average Quantity System checkweigher — more commonly referred to as an AQS checkweigher — is a device used in packaging processes to ensure that products meet specified weight requirements. It automatically weighs items during production, comparing each weight against predefined standards. If a product’s weight falls outside acceptable limits, the system identifies it for correction or rejection. This process helps maintain consistency and compliance with trade measurement laws, ensuring consumers receive accurately weighed products. In Australia and New Zealand, the Average Quantity System (AQS) is used to verify pre-packaged goods sold by weight, volume, length, area, or number, aligning with international standards to ensure fair trade practices.

In effect, an AQS checkweigher gives you the correct e-weight for packaging. The e-weight, represented by the ‘℮’ symbol on packaging, is a marking on packaged goods indicating compliance with the European Union’s Average Quantity System (AQS), ensuring the batch meets declared weight regulations. This system allows minor variations in individual package weights, provided the average weight across a production batch meets the declared quantity. Both Australia and New Zealand apply similar principles, permitting a ‘tolerable deficiency’ while ensuring the batch as a whole remains compliant with trade measurement laws. This approach not only protects consumers but also optimises production efficiency by minimising product giveaway due to overfilling, helping businesses maintain accuracy while reducing costs.

What Does AQS Involve?

Keeping in compliance with AQS requirements will typically involve the following:

  • The AQS E-Mark: AQS and the average system operate concurrently, and inspectors must identify which measurement system applies. Businesses using AQS must mark pre-packaged goods with the AQS e-mark, which must be at least 3 mm high, placed near the stated quantity, and located on the principal display panel. Australian-made products without an e-mark are assessed under the average system by trade measurement inspectors. It is an offence to use a misleading mark resembling an AQS e-mark. For imported products with an e-mark, inspectors may require warehouse testing if production records are unavailable.
  • Shortfall: In national trade measurement legislation, shortfall refers to any instance where production output falls below expectations. In the national single article test, a shortfall occurs when a package contains less than the declared quantity. For AQS or average system testing, shortfall applies to a group of packages of the same kind. Even if most packages meet requirements, a shortfall means the entire group cannot be sold, requiring corrective action by the packer.
  • AQS Threshold: The AQS threshold defines the inspection lot size from which a sample is taken for testing. Inspectors assess this sample to determine if the batch complies with AQS regulations, distinct from internal testing conducted by businesses.
  • AQS Sampling Procedure for NMI Inspector:  Trade measurement inspectors follow statistical sampling practices when selecting a sample from a lot of packages. If the sample is collected directly from the production line, the batch size must equal the maximum hourly output of the production line. For samples taken outside the production line, the batch size depends on the production rate. If the maximum hourly output exceeds 10,000 packages, the batch size must match this output. If the hourly output is 10,000 packages or less, the batch size must not exceed 10,000 packages.
  • AQS Test Procedure for NMI Inspector: To ensure compliance with the Average Quantity System (AQS), inspectors conduct tests based on three key rules:

    1.
    The average quantity of the sampled packages must be at least equal to the declared amount on the packaging.​

    2. The number of packages with a deficiency beyond the acceptable limit must remain within the allowed threshold for compliance.​

    3. No package may have a deficiency that exceeds twice the acceptable limit.​

The Importance of Compliance in Packaging

Keeping compliance with product weight accuracy is the easiest way to ensure industry wide fairness, while meeting regulatory legal requirements and maintaining trust with your consumers. Failing to comply can lead to penalties, costly product recalls, and reputational damage, which may reduce customer confidence and long-term sales. Non-compliance also impacts profitability through fines and wasted resources, while undermining sustainability by increasing material waste and inefficiencies in production.

Keeping up with compliance is advantageous for many more reasons, including:

  • Product Quality Assurance: Packaging regulations go beyond compliance—they help preserve product quality and safety. By setting standards for materials, design, and manufacturing, they ensure products stay protected throughout storage, transport, and use, reinforcing consumer trust in your brand.
  • Consumer Safety: Packaging regulations mandate clear labeling and handling instructions for hazardous materials to protect consumers from potential health risks. These requirements help prevent accidents, ensure proper storage and use, and provide critical safety information in case of exposure. Compliance also supports regulatory standards and reinforces consumer confidence in product safety.
  • Regulatory Compliance: In the ever-evolving packaging industry, meeting regulatory standards is essential as requirements continue to grow stricter across various authorities. Compliance is not just a legal necessity but also vital for safeguarding consumers and the environment. Quality assurance in packaging testing ensures materials meet established standards for safety, recyclability, and labeling. Failure to comply can result in fines, product recalls, and reputational harm, impacting both business operations and consumer trust.
  • Consumer Trust & Brand Reputation: Packaging plays a critical role in shaping consumer perceptions and influencing purchasing decisions. Poor-quality or defective packaging can harm a brand’s reputation, leading to a loss of customer trust and loyalty. Quality assurance in packaging testing helps identify issues with print quality, colour consistency, and overall appearance. By ensuring packaging accurately reflects the brand’s image, companies can strengthen their identity and enhance the consumer experience.
  • Supply Chain Efficiency: Quality assurance in packaging testing plays a key role in maintaining an efficient supply chain. Thoroughly tested packaging is less likely to fail during storage or transport, reducing product damage and supply chain disruptions. This leads to smoother order fulfillment and ensures products arrive in optimal condition. Keeping in compliance can help a business enhance customer satisfaction, while building strong relationships with retailers and distributors.
  • Cost Efficiency: Implementing quality assurance in packaging testing helps improve cost efficiency over time. By detecting and addressing potential issues early in the design and production process, companies can prevent expensive recalls, rework, and legal complications. 

How AQS Checkweighers Help Maintain Compliance

​Automatic checkweighers are essential in production lines for ensuring that each package meets specified weight standards, thereby maintaining product quality and regulatory compliance. They dynamically weigh items during production, automatically rejecting those that fall outside acceptable weight ranges, thus preventing very underfilled or very overfilled products from reaching consumers.

Modern checkweighing systems offer advanced features such as automated adjustments, data logging, and real-time monitoring. Automated feedback mechanisms enable these systems to adjust filling processes dynamically, maintaining consistent product weights and reducing material waste. Data logging capabilities facilitate the collection and analysis of production data, aiding in process optimisation and traceability. Real-time monitoring allows operators to oversee production efficiency and promptly address any issues that arise.

Integrating checkweighers into production lines ensures seamless quality control by providing continuous, inline weight verification without disrupting workflow. This integration enhances overall efficiency, minimises product giveaway, and ensures compliance with industry standards, thereby protecting brand reputation and consumer trust.
