Looking for a diesel generator supplier in China? Here's what separates the pros from the amateurs.
Red flag #1: No factory. Trading companies can't control quality. Always ask for a live factory tour.
Red flag #2: Missing certifications. A real manufacturer has ISO 9001, CE, and at least 5 years of export history.
Red flag #3: No load testing. Every unit should be 100% load-tested before shipping. If they can't show you a video, walk away.
Red flag #4: Short warranty. Reliable suppliers stand behind their products with 12 to 24 months coverage.
Red flag #5: No real references. Ask for client contacts and verify past projects. Real suppliers have nothing to hide.
