To verify a trade company in Guyuan, a region in China’s Inner Mongolia Autonomous Region, you can follow these general steps:

1. **Check Official Sources**: The first and foremost step is to visit the official websites of China’s government agencies, particularly the State Administration for Market Regulation (SAMR) or the local branch.

2. **Search for Corporate Information**: Once on the SAMR website, use their search function to input the company name or registration number. Guyuan-specific information may also be found on the local administrative bureau’s website.

3. **Verify Documents and Licenses**: If the trade company is listed, the website should display any relevant licenses, permits, or business registration certificates. These documents are usually issued by local authorities and confirm the legal status of the company.

4. **Contact the Company Directly**: In case you cannot find all the information directly on the official websites, it’s advisable to reach out to the company via email or phone to verify their details.

Please note that the specific procedures and steps might vary depending on the exact nature of the trade company and local regulations.
