What's the actual official digital tool for the fair?
Why BEST is the platform that matters, and what this guide could and couldn't confirm about a dedicated mobile app.
The tool that actually matters is BEST — the Buyer E-Service Tool, also called the Buyer Service System — the organiser’s own platform for buyer registration and invitation letter applications, covered in detail on the registration page and the invitation-letter page.
What’s confirmed
The organiser runs registration and invitation applications through its own web platform, with a mobile-friendly registration link available alongside the main site. This is the official channel, run directly by the China Foreign Trade Centre rather than any third party.
What isn’t confirmed
Whether a separate, dedicated mobile app exists beyond the mobile-friendly web registration link is something this guide couldn’t verify with confidence.
If a dedicated app matters to you specifically, check the organiser’s own site directly rather than relying on an app-store search, which can surface unofficial or outdated results for an event this size.
A caution worth stating plainly
Registration and the invitation letter are both free and go through the organiser directly. A third-party app or website charging a fee to “help” with either isn’t providing something the official system doesn’t already offer for free — treat a paid version of either process as a convenience purchase at best, not a necessary step.
What’s next
Go through the actual registration process, or check how the invitation letter application works if that’s what you need next.
