According to my experience, the format of inspection power of attorney varies from place to place. As we requested in Nanjing, it is in triplicate, with the name "Power of Attorney for Inspection" and the word IQ written in the upper left corner. We use it in other places such as Jiangsu and Zhejiang. A4 paper can be printed and stamped, which is called "inspection power of attorney", and IQ is also written in the upper left corner. What Shanghai requires is also a couplet, but it is called "entry-exit inspection and quarantine declaration power of attorney". The format is completely different from the previous two, and there is no IQ. The purpose of various inspection forms is the same, but the requirements of commodity inspection bureaus vary from place to place. Just ask the commodity inspection bureau where the factory is located what kind of cooperation it needs.
