You are probably talking about products that have no certificates or standards met, right?+t,V-U5{.B6e9o
It's really painful to be asked for such question. I agree with upstairs, send them a sample to proof directly. If sample is not convenient, you can list some reference customers for him.

that is easy. If your products have some certificats or approval just as CE ,CCC etc.no matter what kind of and which authortiy ,just tell them  seriously .Then tell them that your products must pass strict inspection before they are sold out ,if they need ,ask them to your factory for a spot study ,probably they will not really come ,if they come ,that is a good news ,because your products worth their attention like this .and at last ,just tell them that your products has beenenjoyed a long good reputation of superior quality ,all the customers offer positive feedback.
