The Way to Deal with Unqualified Finished Products Found by QC Staff
If a few unqualified finished products are found by QC staff, the staff will fill the “Bad Product Processing Form" to inform the workshop to repair it. After repairing, the QC staff will check it again and qualified products will be put into the warehouse with other goods; If a whole batch is unqualified, the QC staff will fill the “Bad Product Processing Form" to inform the workshop to reproduce it.

The Way to Deal with Unqualified Products Found in Customer Inspection
If the unqualified product found by the customer inspection, the sales department will send “Unqualified Inspection Report Form “ to the technical department with the unqualified sample (customer provided). Technical department staff will analyze, prepare the analysis report, and put forward corrective and preventive measures. 

The workshop performs corrective actions and arranges rework.
After the implementation of rework, the quality will be inspected by QC staff and by the customer inspection. If it does not pass customer ‘s inspection, it will be qualified for disposal. The Way to Deal with Unqualified Products Returned by Customers The technical quality department analyzes according to the unqualified samples and provides the corresponding corrective and preventive measures in the " Unqualified inspection report form " issued by the sales department. The returned goods can be reworked by the workshop which will organize full inspection, sorting and statistics, and then send statistical reports and unqualified samples together to the technical department. After reworking, the goods without inspection will not be sent into the warehouse. For those goods not able to rework, the factory will re-produce replenishment.

The warehouse should be kept ventilated and dry, and there should be rain, moisture, fire resistant measures. Warehouse materials should be placed neatly, clean and tidy (no dust, no garbage, no debris). Warehouse material’s label content should be complete, clear and correct to facilitate the inventory check and easy to be found. Warehouse materials found in failure, deterioration or damage should be scrapped in time and cleared from the warehouse.

delivery process. Sales staff checks the products in accordance with the requirements of the contract before delivery. At the same time the staff needs to estimate the problems on the way of delivery and takes protective measures. In the transport process, we must always check the quality of the products. As long as there is an issue that may have impact on quality, we need to deal with it immediately, so as not to damage the product. In the course of transport, if due to accident that causes the quality of the goods affected, the staff should immediately report to the management team, to ensure the goods that are delivered to customers meeting the requirements. When the product reaches the destination, it must be signed by the receiver. If the customer requests to provide product quality certificate or quality system certification, we should try to meet customer requirements.
