Three years. The green food mark is a quality certification mark officially registered by the Green Food Development Center in the Trademark Office of the State Administration for Industry and Commerce, and its exclusive right to use a trademark is protected by the Trademark Law of People's Republic of China (PRC).
Products that have passed the green food certification can use the green food logo in a unified format, and the validity period is 3 years, counting from the date of obtaining the certificate through certification. After the expiration of the validity period, the production enterprise must re-apply for certification before continuing to use the mark and changing the number on the mark.
It will take half a year from re-application to certification, during which the production enterprises will be allowed to continue to use the green food logo. If the re-application fails to pass the certification, the enterprise must immediately stop using the mark. In addition, during the three-year validity period, China Green Food Development Center will inspect the products every year according to the environmental, production and quality standards of green food. If it does not meet the requirements, the center will cancel the use mark of the product.
