    WHY inspections?

    First of all, every batch of products has some defects, just like there is no 100% pure GOLD, and like the purer the gold, the harder and costlier to achieve. All manufacturers have, or should have their QC department to minimize the defect rates to an acceptable level. But all inspectors are subjective, or they too, might just check periodically instead of every pieces. The extra pair of eyes will help ensure the quality. But very commonly, lots of factories don't even have in-house QC.


    Secondly, you have a commitment, and should have make a promise to your clients or consumers that you will deliver quality products to their hands. With our service, at a small cost, you can monitor, analyse, and keep track of your quality performance.


    And after all, when you are buying from a supplier, and you want to make sure things like the quality, quantity, packing etc. are as expected before shipments, so that there won't be SUPPRISES upon arrival.

    WHAT is pre-shipment quality inspection?

    We can send an inspector down to the factory to do the inspection on-site during the production and before the shipment.

    Pre-shipment product quality check points:

    • Product specs and customers' requirements
    • Measurements check
    • Quantity verifying
    • Packaging and drop tests
    • Labels & markings, Logos check
    • Aesthetic, surface and function check
    • On-site function check and testing

    How does it work?

    • We will evaluate/validate your bookings; Will send you invoices for payment after bookings confirmed;
    • We will contact the factory to confirm the inspection date and location;
    • 24 hours after the inspections, we will send you the inspection reports with findings, pictures, and comments etc., so that you can decide if the suppliers can go ahead with shipments, or they should rework them first.

    AQL standard?

    It stands for Acceptable Quality Limit (Level): The maximam percentage or proportion of nonconformities in a lot or batch that can be considered as a process average.

    It will also guide you how to determine the sampling size. For general products, the commonly adopt sample size is Level II.
