Canton Fair Invitation Letter Not Downloading? 2026 Troubleshooting Guide

1. Why Is My Canton Fair Invitation Letter Not Downloading?

If you have completed your Canton Fair buyer registration but your invitation letter is not generating, not appearing in your account, or the download is failing, you are not alone. Many Indian buyers encounter this issue, especially during peak registration periods for the Canton Fair 2026 Spring and Autumn sessions.

The official Canton Fair Invitation Letter is generated through the Buyer Service System (BEST) at cantonfair.org.cn. When the process works correctly, the letter appears as a downloadable PDF in your account dashboard. When it does not, the issue usually falls into one of these categories:

• Account or registration status issue: Your buyer account may not yet be fully verified or approved.
• Invitation not yet applied for: Registration alone may not automatically generate the invitation letter — you may need to apply for it separately within the BEST portal.
• Data entry or document mismatch: Incorrect passport details, company name discrepancies, or incomplete uploads can prevent generation.
• Browser or technical issue: The download may fail due to pop-up blockers, incompatible browsers, or connectivity problems.
• System processing time: The invitation letter may not appear immediately after application. Check the current status shown in the official Buyer Service System for updates.

This guide will help you identify the specific problem and attempt to resolve it. If you are looking for the standard step-by-step process to obtain the invitation letter, see our complete Canton Fair invitation letter guide.

2. First Check Your Buyer Service System Account

Before troubleshooting the invitation letter itself, confirm that your Buyer Service System (BEST) account is in good standing:

1. Log in successfully: Visit the official Canton Fair portal (cantonfair.org.cn) and confirm you can access your buyer dashboard. If you cannot log in, reset your password or verify your registered email address.
2. Check account verification status: Look for a verification or approval indicator on your dashboard. If your account still shows as "Pending Review" or "Under Verification," your buyer credentials have not yet been confirmed by the organizing committee.
3. Confirm your registration session: Ensure you have selected the correct Canton Fair session — the 139th Spring Session (April 2026) or the 140th Autumn Session (October 2026). Invitations are session-specific.

3. New Buyer vs Returning Buyer: Which Process Applies?

The invitation letter process differs depending on whether you are registering for the first time or returning as a previous attendee:

New Buyers (First Registration)

If you are registering on the Buyer Service System for the first time, you must complete the full registration process before the invitation letter becomes available. This includes uploading your Indian passport scan, business proof (GST certificate or Certificate of Incorporation), and a compliant digital photograph. Follow our Canton Fair buyer registration process guide to ensure every step is completed correctly.

Returning Buyers (Previous Attendees)

If you attended a previous Canton Fair session, your BEST account may already exist. However, you may need to:

• Update your passport details if your Indian passport was renewed since your last visit.
• Confirm your company information is current and matches your latest Indian business documents.
• Re-apply for the invitation letter for the new 2026 session — previous session invitations do not carry over.

4. What to Check When "My Invitation Letters" Is Empty

If you navigate to the invitation letter section in the BEST portal and find it empty, check these items:

1. Registration approval: Your buyer account must be fully verified and approved before the invitation letter can be generated. Check your account status on the BEST dashboard for the current approval progress.
2. Invitation application: On the BEST portal, completing your buyer registration and applying for the invitation letter may be separate steps. After your account is verified, navigate to the invitation letter section and check whether you need to explicitly apply or request the letter.
3. Session and phase selection: Confirm you have selected which Canton Fair session and phase(s) you plan to attend. The invitation letter is generated for a specific session.
4. Processing time: If you have just applied, the invitation letter may not appear immediately. Check your buyer registration and application status and follow the current instructions shown in the official Buyer Service System before assuming there is an error.

5. What to Check When the Download Button Does Not Work

If your invitation letter appears in the BEST portal but the download button does not respond, fails to produce a file, or produces an error, try these steps:

1. Try a current browser: Try a current browser such as Chrome, Edge, or Safari. Also check whether pop-up blocking, PDF download settings, or browser extensions are interfering with the download.
2. Disable pop-up blockers: The invitation letter PDF may open in a new browser tab or pop-up window. If your browser blocks pop-ups, the download will silently fail. Temporarily allow pop-ups for cantonfair.org.cn.
3. Check your internet connection: A slow or unstable internet connection can cause the PDF generation request to time out. Switch to a stable Wi-Fi connection and retry.
4. Try a different device: If the download fails on your phone, try using a laptop or desktop computer. If it fails on one computer, try another browser or device.
5. Clear browser cache: Cached data from a previous session can sometimes interfere with portal functionality. Clear your browser cache and cookies for the Canton Fair website, then log in again.
6. Check for PDF viewer: Ensure your device has a working PDF viewer installed. On some systems, the browser may download the PDF but not open it automatically.

6. Check Your Buyer Registration Information

Incorrect or inconsistent registration data is one of the most common reasons the invitation letter fails to generate or contains errors. Before contacting anyone, verify these details in your BEST account:

• Full name spelling: Your name on the BEST portal must exactly match the machine-readable zone of your Indian passport. Even minor differences (e.g., a missing middle name or reversed first/last name) can block generation.
• Passport number: Confirm the passport number entered is your current, valid Indian passport. If your passport was recently renewed, you must update the new passport number in the system.
• Company name: Your registered company name should match your official Indian business documents (GST certificate or Certificate of Incorporation). Trade aliases or abbreviated names may cause a mismatch.
• Document uploads: Ensure all uploaded scans (passport page, business proof, photograph) are clear, legible, and in the accepted file format.
