Although some QC Inspection companies will use slightly different terminology, the above covers the general inspections available. Some companies will also offer a Full Quality Control Inspection.

Before placing any orders with a supplier, I would strongly advise a Supplier Evaluation/Audit report, to check & verify their legal & owner details, factory status, product experience, product certification and ability to manufacture your product.

What Does Each Quality Control Inspection Cover & Which Inspection Should I Choose for My Shipment?

Choosing the Quality Control Inspection that best serves your purpose will depend on your product and what specific points you want checked to ensure they’re correct before paying the final balance and shipping your product. The following is a brief guide of what to expect from each QC inspection and this will vary slightly for different inspection companies.

PPI: Pre-Production Inspection

DPI: During Production Inspection
This will include assembly line checks, product specifications, manufacturing quality and random product tests including features and functions. This will also include packaging and packing details.

PSI: Pre-Shipment Inspection
As the name suggests, this is done when all the production is finished and approximately 80% – 100% of the products are finished. This inspection will include opening of random cartons and checking a few samples from each for quality of materials, workmanship and product specifications as well as function and feature testing. This inspection will also include carton packing, shipping marks, total quantities and shipping documents.

This will include a carton count being loaded, safely loading of the container, document check and evidence of the container seal. If you have multiple products, you can request the loading procedure for each model.

What happens If The QC Inspector Finds Product Faults During The Inspection?

Generally, faulty products will be noted, photographed and documented in the report with the level of importance to the product, typically, a minor or major fault. The faults will also be pointed out to the factory and their solution comments noted. It is up to the customer to agree with the supplier whether to accept the solution.

What am I Going To Do with The Quality Control Report?

The Quality Control report will identify the problems found with the products tested. Generally, there will be an agreed quantity between you and the QC inspection company as to how many products are tested, and this is typically 5% – 8% of the total products. There should also be an agreement between you and your supplier for an ‘acceptable’ level of defect rate and this is typically 1%.

After receiving the report, you’ll be in a better position to know how to proceed and possibly negotiate with your supplier.

What if My Supplier Does Not Accept a 3rd Party Quality Control Inspection?

If your supplier does not accept a 3rd party QC inspection, I would advise not working with that supplier.

Yes and it’s important to get the date of the inspection correct so the stage of production is optimal to carry out the inspection you choose. It’s also advisable to request a member of staff to accompany you to all the locations your order is being prepared and stored and a reasonable testing area.
