Implementation of the “Outline for Type Evaluation of Electronic Pricing Scales (Trial)” Strengthens Associated Control over Weights
New regulations have been implemented: “shell-opening lock, one scale–one code, three codes–one seal.” Electronic pricing scales will automatically lock when their shells are opened and can only be unlocked with an authorized dynamic password. Each scale is assigned a unique identification code at the factory, enabling full traceability across the entire supply chain—production, sales, maintenance, and verification. Starting in 2027, only products compliant with the new regulations will be required, thereby promoting the standardized application of weights in trade settlement.

The “Outline for Type Evaluation of Electronic Pricing Scales (Trial)” was officially implemented on January 8, 2026. It strengthens anti-fraud control over electronic pricing scales through technical requirements such as “shell-opening lockout, unique identity traceability, and unified sealing of three codes,” thereby indirectly linking to standards for the use of weights and promoting the upgrade of the metrological regulatory system.
Analysis of the Correlation Between Core Control Measures and Weights
1. Shell-breaking lock removal and authorized unlocking
- Requirement: The electronic pricing scale shall automatically lock upon unauthorized opening of its housing, and only authorized personnel may unlock it using a dynamic password.
- Weight calibration linkage: Prevents unauthorized disassembly and modification that could tamper with measurement parameters (such as adjusting sensor sensitivity), thereby ensuring the accuracy of weight calibration. If the device is illegally modified, the lockout function will immediately disable its operation, preventing fraudulent scales from entering the market.
2. Unique Identity Information Traceability**
- Requirement: Each weighing instrument shall be assigned a unique identification code (including production and maintenance codes) upon leaving the factory, and information shall be verified online during mandatory verification.
- Weight calibration linkage: As a standard metrological instrument, weights must be uniquely associated with the corresponding scale. For example, verification records must be linked to the scale’s identification code to ensure full traceability of the weight calibration process and to prevent scenarios such as “one weight used on multiple scales” or “falsified verification.”
3. Unified “Three Codes and One Seal” Management
Requirement: The production code, maintenance code, verification code, and lead seal must be complete and valid before verification can be performed.
Weight calibration correlation: The integrity of the lead seal is a critical indicator of compliance with verification standards. If the lead seal is broken, even when calibrated using standard weights, the scale may still exhibit measurement inaccuracies due to internal modifications; therefore, the “three weights and one seal” requirement indirectly ensures the validity of weight calibration.
Implementation Objectives and Industry Impact**
Addressing cheating at the source: Employing technological measures to eliminate practices such as dismantling and modifying devices and falsifying verification records, thereby reducing the prevalence of “ghost scales.”
End-to-end regulatory oversight: covering the production, sales, use, and verification stages to ensure compliance with standardized procedures for weight calibration, lead-seal management, data verification, and other processes.
Consumer Rights Protection: Strengthening metrological accuracy to reduce short-weighting and under-measurement in trade settlements.
Transition Arrangements
Manufacturing enterprises: Effective January 8, 2026, the production and sale of weighing instruments that do not comply with the new regulations are prohibited.
Applicable entities: Compliance-certified scales must be used starting January 8, 2027; existing networked scales may continue to be used until January 8, 2030.
Supporting Measures
Smart Regulatory Platform: The State Administration for Market Regulation has launched a national smart metrology regulatory platform for electronic weighing scales, enabling full-lifecycle data management and further enhancing transparency of information such as weight calibration and verification records.
Industrial Upgrading: As of January 2026, more than 90% of enterprises have completed technological upgrades, laying the industrial foundation for the implementation of the new regulations.
In summary, the new regulations establish a closed-loop system for preventing fraud in electronic pricing scales through technical controls and institutional design. Although they do not explicitly mention weights, by strengthening measures such as device identification, verification procedures, and lead-seal management, they indirectly ensure the standardization of weight calibration and the accuracy of measurement results, thereby providing more reliable metrological assurance for trade settlement.
