Pre-shipment inspection (PSI) is one of the many quality control tests conducted by Nanchang Ganjiang Bush Factory. This inspection is based on standard QC testing or on customer request. Based on these criteria and procedures, samples are randomly selected and defects are checked. For us, pre-shipment inspection is an important step in the quality control process and a way to check the quality of the bronze bushing before shipment.
