Legal analysis: product certificate processing flow: 1. The production enterprise applies for and receives the application form; 2, the administrative department of quality supervision review materials; 3. The samples shall be sampled and inspected by the statutory quality inspection agency; 4, submitted to the leadership for approval. Besides knowing how to handle the product certificate, you also need to know that the product certificate should include the following contents besides the product model, name, specification, production unit and address: (1) Implement the product standard number. (2) Inspection items and their results or inspection conclusions. The products delivered in batches shall also include: batch number, batch number and part number of the sampled parts. (3) Inspection date, factory date, inspector's signature or seal of the product (can be expressed by inspector code). The Product Quality Law clearly stipulates that products or their packaging should have product quality inspection certificates. On the one hand, it requires producers to ensure product quality, on the other hand, it allows users and consumers to identify product quality. Provide manufacturer, product model, specification and related parameters, signature of quality inspector, product or product inspection lot, product or product batch number. Sometimes inspection items are attached, indicating that the modified products or products of this batch have been inspected according to the ex-factory inspection regulations and are qualified. A product certificate is a certificate, label or seal attached to a product or product package by a manufacturing enterprise to show that the ex-factory product has passed the quality inspection, and it is an express guarantee made by the enterprise for the quality of its products. Unqualified products are not allowed to leave the factory, which is the minimum requirement of the enterprise quality assurance system. In general, products with complex performance and structure, large-scale durable consumer goods and high-end high-value products all adopt certificates of conformity. Such as refrigerators, color TVs, washing machines, jewelry, computers, automobiles and other products. Use qualified labels for consumer goods, such as clothing, shoes, food, etc. In order to facilitate the labeling of producers, some products can be printed with the word "qualified" on the labels, instructions and packaging. Such as cosmetics, health products and medicines. In short, marking on the product quality inspection certificate should be conducive to ensuring product quality, protecting the legitimate rights and interests of users and consumers, and also beneficial to producers and facilitating production. It should be noted that the following two issues should be paid attention to when marking the product quality inspection certificate: 1, which is only applicable to qualified products after inspection, not to unqualified products; 2. This regulation is only valid for products produced in China and sold in China.
