Sometimes, factories may be dishonest, and the samples sent out may have been carefully selected or even specially made to showcase the best product condition. The customer is concerned that these samples may not represent the actual product quality in mass production. In order to understand the true quality level of the product, check whether the supplier has manufactured and produced it themselves, and whether it meets the order requirements and the quality level of mass production, the customer will send a third-party randomly selected sample to the customer for verification. In this way, the customer can understand the true quality level of the product and avoid any hidden dangers from the supplier.
