what are you going to do if you do not inspect production, and you get a shipment of unsaleable products?
No 1
Double check if all goods are unsellable. If not, it might be worth the cost to sort the defective pieces out.
No 2
Double check if some of the defective products can be reworked, or have to be thrown away.
If they can be reworked, you have some options:
- Sending the defects to China for repair(quite hard, since Chinese Customers do not allow for defective goods to be imported into China).
- Decide that the value of the goods do not make it worthwhile to rework, or throw them away.
- Do the repair in your location.
- Hire others to help.

The pre-shipment inspection is the last chance for the buyer to detect defects and identify unacceptable quality before the shipping of the goods. What to do after a failed inspection? Buyers can reject lots before they are shipped but there are other alternatives to take into consideration.
- Refuse the goods (seldom a choice)
- Ask the vendor for a discount and ship the goods
- Ship the goods anyway
- Ask the vendor to rework products
- Ask the vendor to sort out defects
Most buyers ask their vendor to rework or replace faulty goods even though it delays the shipment. The vendor usually agrees on it. Afterwards the buyer has two choices:
- Believe the vendor did improve things, pay and ship the goods (risky)
- Re-inspect the goods to verify whether or not they have been reworked properly, and no new defects appear during the reworking process (most reliable)
For the re-inspection (usually paid by the supplier), the standard pre-shipment inspection protocol is used to give another general overview of the quality of the goods. Most third party inspection companies send another inspector, different from the previous inspection. This method identifies all kinds of defects and confirms whether or not the rejected defect(s) have disappeared.
As a matter of fact, by reworking the goods, there is always the risk that new defects appear, only the pre-shipment inspection will allow those to be identified.
It is possible to request a third party inspection company to sort the defects when only 1, 2 or 3 defect types caused the inspection to fail. As it focuses on few defects only, a much higher quantity of goods can be inspected within the same amount of time, ensuring a higher representativeness of the sample. It gives a better idea of the importance of those defects within the overall order. Moreover, the buyer has two choices:
- Request the rework of the sorted goods and follow the choices of replacing/reworking the goods as above
- Ship only the acceptable goods
