Canton Fair Invitations: Factory Letter vs. Official Letter
# Canton Fair Invitations: Which One Works?
To apply for a Chinese Business Visa (M-Visa), you must prove to the embassy that you have a legitimate business reason to enter the country. This requires an Invitation Letter.
Many first-time buyers simply ask a factory they met on Alibaba to send them a letter. Depending on your passport, this can lead to an immediate visa rejection.
> **💡 Withyou Trip Expert Verdict:**
> "A standard PDF letter with a factory's red stamp is the weakest form of invitation. If you hold a passport from a country with high visa rejection rates, the embassy will ignore a factory letter because they are easily forged. You MUST use the **Official Canton Fair E-Invitation**. It contains a secure barcode that the embassy can instantly verify in the Chinese government database."
## 1. The Visa Invitation Power Matrix
| Type of Letter | Issuing Authority | Visa Approval Strength |
| :--- | :--- | :--- |
| **Canton Fair E-Invitation**| Chinese Ministry of Commerce | ⭐⭐⭐⭐⭐ (Guaranteed legitimacy) |
| **Government PU Letter** | Local Provincial Government | ⭐⭐⭐⭐⭐ (Hard to get, for VIPs) |
| **Canton Fair Paper Letter**| Chinese Ministry of Commerce | ⭐⭐⭐⭐ (Used for strict embassies) |
| **Private Factory Letter** | Any registered Chinese company | ⭐⭐ (High scrutiny by consular staff) |
## 2. The "Red Chop" Requirement
If you do use a letter from a private factory (for a sourcing trip outside of Canton Fair dates), it must be legally flawless.
* A Western signature at the bottom means nothing in China.
* The letter must be stamped with the company's **Official Red Chop (Seal)**. This seal is registered with the Chinese police and acts as the company's legal signature. Without the red stamp, the embassy will immediately reject the letter as fraudulent.
## 3. How to Generate the Official E-Invitation
The process is entirely free and digital.
1. Go to the Canton Fair **BEST (Buyer E-Service Tool)** website.
2. Register your company details and upload your passport MRZ page.
3. Once approved, click "Pre-application for E-Invitation Card."
4. Download the generated PDF. The consular officer at your local Chinese embassy will scan the barcode on this PDF to approve your M-Visa.
## ❓ Frequently Asked Questions (FAQ)
**Q: Can I use the Canton Fair Invitation Letter if I am also visiting factories in other cities?**
A: Yes. The Canton Fair letter is accepted as a blanket "Business Reason" for your trip. Once you enter China on your M-Visa, you are free to travel domestically to Shenzhen, Ningbo, or Shanghai to visit other suppliers.
