Site Visit Guide: What to Look for When Visiting a Chinese Factory

Customs data platforms reveal a supplier's real export history. You can see what products they've shipped, to which countries, at what volumes, and how frequently. A supplier claiming years of experience but showing only a few shipments is a red flag. Conversely, a supplier with consistent shipments to reputable buyers in your market is a strong positive signal. Use this data to prioritize which suppliers to visit.

Phone calls reveal more than emails. A legitimate factory manager can answer technical questions about production processes without checking. A trading company representative will often need to 'confirm with the factory' for basic technical details. Schedule a voice or video call early in your evaluation. Listen to how questions are answered — hesitation, vagueness, and over-promising are all warning signs.

A legitimate Chinese factory should be able to provide: business license, export license, third-party audit report, client testimonials with contact information, product certifications, and a physical factory address verifiable on Google Maps. If any of these is missing, ask why. A trading company can be a good partner but should be transparent about their role. Never work with a supplier who misrepresents their identity.

Google Maps Street View is a powerful but underused verification tool. Search the factory address and check: does the location match the description? Is the building size consistent with claimed production capacity? Does Street View show the factory sign in the photos? I've caught suppliers claiming factory status when Street View showed a residential apartment building. This one check takes 2 minutes and costs nothing.
