15. What happens if non-confirming goods are found when the shipment arrives?

It is extremely rare that non-conforming goods make it out of the factory if TOPWIN is hired. In the vast majority of cases, the root cause turns out to be damage during shipping or shipments were approved after a failed inspection and the buyer trusts the factory (who was likely supposed to rework the goods) enough to ship without having performed a re-inspection or a defect sorting service. Therefore, we highly recommend you to book re-inspection or defect sorting service after a failed inspection and to work with your shipping partners to insure the product against damage in transit. TOPWIN guarantees that we will inspect the product to the standard and methods approved by the client (including chosen sampling size). In the event our inspectors do not follow the agreed standards, TOPWIN will make a refund of up to 5 times the price of the inspection.


16. Why doesn't TOPWIN provide a warranty on behalf of the supplier?

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 the sake of example, say there are 100 master cartons in an order and 50 units per master carton 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 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, TOPWIN does 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 the interests of the client. Negotiating such terms with the supplier is outside of the scope of our business at TOPWIN, but our endorsed Partners can help with the negotiations and contract review.


17. Where do I send my approved samples of my product?

In order to save time and money, we advise you to send it directly to your factory, in a sealed package to our attention. In case you do not trust enough your factory or vendor for this, you can send it to our closest office. To know to which office to send it, check our offices address on your dashboard or contact your account manager.
How to decide sample plan and inspection level against your


AQL Table




How to select suitable level by:

Level I: For low price, big lots with same production line or same artwork, same order with well record, low risk products to save time, cost;
Level Ⅱ: most products and product with same production line or same artwork, reasonable time and cost with more than 97.5% accurate for the whole lots;
More than 95% client choose this level and we suggested to use it;
Level Ⅲ: For high price, small lots with different production line or artwork, first order, high risk products to be safety;


How to select acceptable quality levels (AQL)

  • Critical for not allowed of safety and major defects from code numbering of 0.01 to 4.0 according to price, quantity, products, risk high to low, eg:
  • 0.65 for high risk product and 1.5/2.5 for normal products.
  • Minor defects from code numbering of 1.0 to 10 according to price, quantity, products, risk high to low, eg:
  • 1.5 for high risk product and 4.0/ 6.5 for normal products.
