As it is not economically viable for most clients to inspect every unit in the order, AQL tables determine the number of units to be inspected which will yield a statistically reliable sample size. In other words, if the inspection on the randomly selected lot goes well, then it is statistically unlikely that defects will be found in the rest of the order. For example, if there are 100 master cartons in order and 50 units per master carhttps://www.tc-inspection.com/what-is-your-service-guarantee_n18ton for 5000 units total. Our inspectors would open at random a select set of master cartons (the square root of the total number of cartons) and further select at random a set of individual units inside that master carton as per the sampling size chosen by the client. However, if the supplier knew they had a few dozen defects and packaged the defects all together in one section of one master carton, then it would be statistically unlikely that our inspector would find this pocket of defects. For this reason, we do not provide a warranty on behalf of the supplier. But we stress to our clients that they should have robust POs, warranty terms, and payment terms with their suppliers that protect their interests. Negotiating such terms with the supplier is outside of the scope of our business. TEACHER INSPECTION company is neither an insurer nor a guarantor and disclaims all liability in such capacity. Client seeking a guarantee against loss or damage should obtain appropriate insurance.

Sometimes, the quality of overseas production is not as good as expected, which may lead to customer rejection or product recalls. Thus it is essential to have someone oversee the production to avoid defective goods being shipped. You may travel on your own, but it is costly and time-consuming, you may consider asking the supplier to do the job, but usually, the job is not professionally done or the supplier is too close to the factory to disclose the true and complete findings to you. In summary, third-party quality control could be the best solution for overseas production, in addition to establishing your QC team.
