Canton Fair Invitation Letter Guide

You cannot just book a flight to China and show up. To enter mainland China for business, you must apply for an M-Visa (Business/Trade Visa) at the Chinese Embassy or Consulate in your home country.

The Embassy will ask you for one critical piece of paper: Proof that a legitimate Chinese entity is expecting you. This is the Invitation Letter.

💡 Withyou Trip Expert Verdict: "The smartest and easiest way to secure your M-Visa is to use the Official Canton Fair BEST System Invitation Letter. Do not bother asking random factories to draft letters for you, as Embassies heavily scrutinize factory letters for fraud. The official letter generated by the Canton Fair website is pre-vetted, universally respected by Chinese Embassies globally, and guarantees the smoothest visa approval process."

  2. Register a new account using your passport details.
  3. Click on "Pre-application for Buyers Badge."
  4. Once your badge is pre-approved, you can click "Apply for Invitation."
  5. The system will instantly generate a personalized PDF.
• The Execution: You print this PDF and include it in your massive stack of paperwork when you apply for your visa at the Chinese Visa Application Service Center (CVASC).

3. The "Factory Letter" Backup Strategy

Sometimes, you are arriving in China a week before the Canton Fair starts, to visit a factory in Shenzhen.

• The Reality: The Embassy might question why you are arriving on April 5th if the Fair doesn't start until April 15th.
• The Fix: In this scenario, you need BOTH the Canton Fair Letter and a supplemental Factory Invitation Letter.
• The Strict Rules for Factory Letters: The Embassy will reject the factory letter if it is just a typed Word document. It MUST be printed on the factory's official letterhead, state your exact dates of travel and passport number, and most importantly, it MUST be stamped with the factory's Official Red Circular Company Chop (公章) and signed by the legal representative.

❓ Frequently Asked Questions (FAQ)

Q: Do I need the original physical letter mailed to me from China? A: No. In the past, Embassies demanded the physical paper. Today, for 95% of Western nationalities, the Embassy will accept a high-quality color printout of the scanned PDF (whether it's the Canton Fair letter or the Factory letter). Just make sure the red stamp on the factory letter looks crisp and legible in the printout.
