Mingming Henmang offers tenfold compensation for weighing price differences; a Shenzhen lawyer analyzes consumer rights protection and compliance boundaries.
Lead
On September 7, 2026, Mingming Henmang Group publicly apologized for weighing issues at its Ling Shi Hen Mang and Zhao Yiming Snacks stores, announced the establishment of a special fund for advance compensation, and promised that starting that day it would compensate for confirmed weighing errors at ten times the price difference of the goods. At the same time, the company introduced rectification measures including uniformly equipping standard weights, daily scale calibration, launching a scale monitoring system, retaining traceable weighing records, and assessing employees on cashiering standards. This incident quickly sparked public discussion about measurement integrity in the retail industry. From the perspective of a Shenzhen lawyer, this is not only an individual case of corporate crisis public relations, but also involves legal issues at multiple levels, including consumer rights protection, liability for metrology violations, and corporate compliance system development. How can consumers protect their rights according to law when encountering similar situations? What is the relationship between the tenfold compensation voluntarily promised by the company and statutory compensation standards? This article analyzes these issues one by one in light of the Consumer Rights Protection Law, the Metrology Law, and other relevant provisions.
I. Legal Characterization of Inaccurate Weighing: The Boundary Between Measurement Violations and Consumer Fraud
Electronic scales used in retail stores are measuring instruments subject to mandatory national verification. Article 9 of the Metrology Law of the People's Republic of China explicitly provides that working measuring instruments listed in the catalogue for mandatory verification and used for trade settlement shall be subject to mandatory verification; those that have not been submitted for verification as required or that fail verification shall not be used. In addition, Article 46 of the Implementing Rules of the Metrology Law sets out administrative penalties, including confiscation of the measuring instruments, confiscation of illegal gains, and fines, for the use of unqualified measuring instruments or for tampering with their accuracy. If a store's electronic scale has been manually adjusted or intentionally tampered with to affect its accuracy, the market supervision and administration department may investigate and punish the matter in accordance with the Metrology Law and Article 56 of the Law of the People's Republic of China on the Protection of Consumer Rights and Interests, and in serious cases may order suspension of business for rectification and revoke the business license.
At the civil level, whether inaccurate weighing constitutes fraud depends on the circumstances. If it is merely an occasional error caused by equipment failure or employee negligence, it is generally regarded as non-conforming performance of a contract, and consumers may demand compensation for the price difference or a return. However, if a store systematically underweighs over a long period through "rigged scales," it may be deemed fraudulent conduct. Under Article 55 of the Law on the Protection of Consumer Rights and Interests, where a business operator commits fraud in providing goods or services, it shall, at the consumer's request, increase compensation for the losses suffered, and the increased compensation shall be three times the price paid by the consumer for the goods; if the increased compensation is less than 500 yuan, it shall be 500 yuan. In other words, the statutory punitive damages are "refund plus three times compensation, with a minimum of 500 yuan," rather than the "ten times the price difference" voluntarily promised by the business.
II. Legal Effect and Practical Considerations of an Enterprise's Commitment to "Tenfold Compensation for Price Differences"
Mingming Henmang's commitment this time to "compensate ten times the price difference for misweighed goods" is, in nature, a compensation promise voluntarily made by the business operator that exceeds the statutory standard. According to Article 472 of the Civil Code and Article 16 of the Law on the Protection of Consumer Rights and Interests, when providing goods or services to consumers, business operators shall fulfill the obligations prescribed by law, but if the parties agree on a standard higher than the statutory standard, that agreement shall prevail. The compensation standard publicly promised by an enterprise constitutes an offer to consumers, and once consumers accept it, it creates binding contractual force. Therefore, as long as consumers can prove the weighing error, the enterprise shall perform according to the promise and cannot go back on it on the grounds that "the statutory standard is lower."
However, consumers need to pay attention to several practical points. First, the calculation base for tenfold compensation is the "price difference," not the total price of the goods. For example, if the actual amount payable is 10 yuan but 12 yuan is charged due to incorrect weighing, the price difference is 2 yuan, and the tenfold compensation is 20 yuan. Adding the refund of the 2 yuan overcharge, the total is 22 yuan. Second, the compensation channel promised by the enterprise is advance compensation from a special fund. Consumers should keep evidence such as shopping receipts, weighing photos, and re-weighing records, and apply through the store or official customer service. Third, if the enterprise refuses to compensate according to its promise, consumers can claim liability for breach of contract under the Civil Code, or file a complaint with the market regulation authorities or bring a lawsuit in court. Consumers in Shenzhen can also quickly protect their rights through the online complaint platform of the "Shenzhen Consumer Council."
From the perspective of legal practice, a company's proactive move to raise compensation standards serves, on the one hand, to quickly quell public opinion and repair its reputation, but on the other hand, it may also be regarded as evidence of an "admission of fault." In subsequent administrative penalties or class-action litigation, such a commitment could become a fact unfavorable to the company. Therefore, when making similar commitments, companies should simultaneously assess the legal risks to avoid "paying the money and still leaving a handle for others to use."
III. Compliance Value of Weight Information Traceability and Monitoring Systems
In this rectification by Mingming Henmang, the measure with the greatest legal significance is "recording weighing information and transmitting it back to headquarters, set to be traceable and tamper-proof." According to the Electronic Signature Law of the People's Republic of China and the Supreme People's Court's Provisions on Evidence in Civil Procedure, electronic data may be used as evidence, but it must meet the requirements of authenticity, integrity, and relevance. If an enterprise can ensure through technical means that weighing data is uploaded in real time and cannot be tampered with, then in the event of a dispute, such data can be used both to prove its own innocence and as a basis for compensating consumers.
From a compliance perspective, this mechanism also helps enterprises respond to inspections by market regulatory authorities. The Metrology Law requires units using measuring instruments subject to compulsory verification to establish a metrology management system and appoint full-time or part-time metrology management personnel. By launching a scale monitoring system, conducting daily scale calibration, and uniformly equipping standard weights, enterprises are essentially fulfilling their statutory metrology management obligations. If an enterprise fails to establish the corresponding system, it may face heavier penalties once measurement problems are discovered. As a frontier region in national market regulation reform, Shenzhen has consistently been stringent in investigating and punishing metrology violations, and enterprises should take this as a warning.
In addition, consumers' right to request re-weighing on site and to use standard weights for verification derives from the right to fair trade stipulated in Article 10 of the Consumer Rights Protection Law. Business operators may not refuse consumers' reasonable requests for re-verification on grounds such as "company rules" or "system issues." If a store refuses re-weighing or obstructs a consumer from gathering evidence, the consumer can call 12315 to file a complaint, and the market regulation authorities may, in accordance with Article 56 of the Consumer Rights Protection Law, order correction and impose a fine.
IV. Consumer Rights Protection Pathways and Lawyer's Recommendations
For ordinary consumers, when encountering weighing issues, they can handle them through the following steps: First, request an on-site reweighing and use the standard weights provided by the store to verify it themselves, while recording a video as evidence; second, ask for and check the shopping receipt to confirm the product name, unit price, weight, and amount; third, apply for compensation through the company's official channels and keep a record of the communication; fourth, if the company refuses compensation or handles the matter unfairly, file a complaint with the market regulation authorities or apply to the consumers' committee for mediation; fifth, if a large amount of money is involved or it is a group dispute, a lawyer may be entrusted to file a civil lawsuit and seek punitive damages.
For enterprises, this incident has sounded the alarm on measurement compliance. Retail companies are advised to improve their compliance systems in the following areas: first, establish a ledger of measuring instruments to ensure all electronic scales are verified on schedule; second, implement daily scale calibration and regular inspection systems, and keep records; third, improve employee training and assessment by incorporating measurement standards into cashier operating procedures; fourth, establish a rapid response mechanism for consumer complaints to prevent minor disputes from escalating into public opinion incidents; fifth, make compensation commitments higher than statutory standards prudently, and consult professional lawyers to assess the legal consequences when necessary.
