First of all, you need to find out whether you are applying for SGS factory inspection, which customer you represent and which country the customer is from.
If you don't apply yourself, you should ask the foreign trade company. Generally, the factory inspection date can be agreed, and the foreign trade company or SGS will give you the factory inspection form before the scheduled date.
If it is a human rights factory inspection, it is nothing more than routine items such as wages and working hours, environmental health and safety. If anti-terrorism is added, there will be more security requirements.
