What are the procedures pre-shipment inspection needs to be performed?

The following are the steps involved in the pre-shipment inspection process.

1. Place an order

Customers who want to maintain the quality of their goods can request a pre-shipment inspection. For most goods, this is not mandatory. However, medical equipment must always be inspected.

2. On-site inspector

Product inspection is usually performed at the manufacturing site or factory. If any discrepancies are found, the item will be taken to an off-site laboratory for further testing.

3. Off-site shipping inspection

This applies to items containing prohibited or toxic chemicals controlled by the destination market.

4. Quantity Inspection

The inspector counts the shipping boxes and ensures that the correct number of items and cartons are shipped to the correct address. Packaging is also checked to see if proper materials are used and if the items have the correct shipping labels. Afterwards, the buyer and seller agree on payment and the bank initiates payment.

5. Random Sampling

The inspector takes random samples of the product for evaluation. All accredited pre-shipment inspection services use the internationally recognized statistical sampling method ANSI/ASQC Z1.4 (ISO 2859-1). The number of items they select (Acceptance Quality Limit or AQL) is also the maximum number of defects allowed in the lot before it is rejected.

6. Appearance Inspection

This involves checking the overall appearance of the product for any visible defects or flaws in production. Any visible defects are identified and assigned to one of three categories: minor, major or critical, depending on the tolerance level agreed between the manufacturer and supplier.

7. Volume Verification

The agent then checks all dimensions and sizes (height, width, length, weight) and ensures that the production meets the customer's specifications.

8. Functional Verification

Items are tested to check that they are working properly. This is usually used for apparel and footwear.

9. Safety Testing

Safety testing is divided into mechanical safety testing and electrical safety testing. For mechanical testing, items with moving parts (such as bicycles) are checked for sharp edges or faults that could cause accidents or injury to users. Safety accessories such as hinges and screws are also verified.

Similarly, for electrical testing, electrical or electronic products are tested in a laboratory before they are certified and ready for use. Tests such as high voltage, grounding continuity and current testing are performed prior to clearing the item.

10、Inspection report

Finally, the information collected after the inspection process will be compiled into a comprehensive inspection report. This report includes a list of all failed and passed tests, major findings and inspector comments.
