If the quality inspection fails and you need to reapply for shipment, you first need to conduct a detailed analysis and inspection of the unqualified products to find out the cause of the problem and make improvements.

Then, when reapplying for shipment, you need to provide a revised quality inspection report and related certification materials, and ensure that the product meets the standard requirements.

Before applying for shipment, you also need to communicate with the customer or relevant departments, explain the handling of the problem, and obtain their approval. Finally, after strict quality inspection and confirmation, you can reapply for shipment.
