What are the behaviors prohibited by law in the product quality law?

in the market economy, some unscrupulous producers and sellers do not rely on efforts to improve product quality to enhance their competitiveness, but use fraudulent means to conduct unfair competition on product quality issues, which seriously damages consumers' interests and disrupts the market economic order. For this reason, the product quality law has made clear prohibitions against the typical product quality fraud in practice. Including: 1. It is forbidden to forge or fraudulently use quality marks such as certification marks. The product quality law stipulates that producers shall not forge or fraudulently use quality marks such as certification marks. Forging quality marks refers to the act of using forged quality marks on products that do not actually exist; Fraudulent use of quality marks refers to the unauthorized use of the corresponding quality marks of the license issuing agency on products that have not passed the examination by the license issuing agency. At present, the common quality marks in China are mainly product quality certification marks. For example, Fiona Fang certification mark, Great Wall certification mark, PRC certification mark issued by certification bodies recognized by the State Council product quality supervision department, and pure wool mark issued by International Wool Bureau, etc. Product quality marks such as quality certification marks indicate the level of product quality, which is a sign of product quality reputation, and can play the role of reputation guide for consumers to buy products. An enterprise can use the quality mark on the product only after the organization with certification qualification determines that the quality of the product meets the conditions for issuing the quality mark according to the prescribed procedures. Therefore, any illegal use or impersonation of these quality marks is a concealment of the truth of product quality and a deception to consumers, which should be prohibited by law. 2. It is forbidden to forge the origin of products. Producers and sellers must indicate the origin of the product on the product or its packaging, which must be true and shall not be forged. For example, mineral water that is not produced in Laoshan, Qingdao, shall not be marked as Laoshan; Clothing that is not produced in Shanghai shall not be marked as Shanghai. A certain product produced in some specific areas has only good quality and performance, which is often related to the natural conditions and traditional manufacturing methods in this area. Consumers are more trusting and fond of the specific products produced in such specific areas. Taking advantage of consumers' psychology to forge the origin of products is an act of deceiving consumers and unfair competition, which must be banned. 3. It is forbidden to forge or falsely use the factory name and address of others. The factory name and address marked on the product or its package must be true. The "forgery" mentioned here refers to the fabrication of a nonexistent factory name and address out of nothing; The "fraudulent use" mentioned here refers to the unauthorized use of the factory name and address of other enterprises. Forge the name and address of the manufacturer of the product and conceal the real producer. First, when the product has quality problems, it is difficult for consumers to find the ultimate responsible person, which infringes on consumers' right to know and harms consumers' interests. Fraudulent use of other people's factory names and addresses is often manifested in the fraudulent use of the factory names and addresses of well-known enterprises in practice, with the aim of using the established market reputation of well-known enterprises to promote their own products. This is not only a deceptive behavior to consumers, but also a typical unfair competition behavior, which must also be prohibited. 4. It is forbidden to adulterate and adulterate the products produced and sold, and pass the fake off as the real one and pass the inferior one as the good one. "Doping, adulteration" refers to the act of adding ingredients that do not belong to the product, which leads to the decline of product quality. For example, mixing talcum powder in bean products, mixing furnace ash in chemical fertilizers, etc., usually mixing cheap things in products to reap huge profits. "Fake is genuine" refers to the act of passing off a product other than this one. For example, artificial leather is used as genuine leather, and copper plating is used as gold products. What I said here does not include the act of counterfeiting trademarks and patents. Counterfeit trademarks or counterfeit patents are regulated by trademark law and patent law respectively. "shoddy" means that products with low quality grade pass off as products with high quality grade, such as passing off second-class products as first-class products. In a broad sense, "shoddy" also includes the act of passing off unqualified products as qualified products. Adulteration, adulteration, passing the fake as the real and passing the inferior as the good in the products produced and sold are all acts of quality fraud that harm the interests of consumers and must be prohibited.
