Validity period of product certificate:
The product quality inspection certificate is a qualified mark added to the product or its packaging by the production enterprise, which indicates that the quality of the ex-factory product meets the specified technical requirements and has passed the inspection by its quality inspection institutions and inspectors.
The product quality inspection certificate is not approved by any competent department or superior unit, but produced by the production enterprise itself. There are three main forms of product quality inspection certificate: certificate of conformity, inspection seal and inspection process number seal.
The product quality inspection certificate is an express guarantee made by the production enterprise for the quality of the products it produces and sells to ensure that the quality of the products it produces and sells meets the specified technical requirements. Therefore, it can only be used on products that pass the inspection, and products that fail the inspection or fail the inspection cannot be used.
If the certified products are unqualified, the production enterprises shall bear corresponding legal responsibilities. If a producer or seller deceives users and consumers and intentionally attaches a certificate of conformity to unqualified products, it constitutes an illegal fact that unqualified products pass off as qualified products. According to the regulations, producers and sellers should be investigated for administrative responsibility and criminal responsibility.
