--We can clearly judge that the picture above is a factory, the company name and factory buildings are all taken in the photos.
--As in the picture above, if you only see the production office or workshop without the company name, is probably a trading company.
With the three points above, in most cases, you can judge whether a company is a factory or a trading company. However, there will be exceptions. For example, some factories and sales departments do not work in the same place and register online using the address of the sales department office, or some intermediaries do not have Trading or Imp & Exp in their names, and then enter an address that not real on the internet.
If you want to accurately judge whether a company is trustworthy, you can take our supplier verification service. We can verify the company registration information on the official government website or we can go to the factory for a verification in person. For more information, see the following website:
