This is a step that typically gets ignored by many who source in China. 
Without an accurate and rigorous quality standard, it is all too tempting for factory to allow products to slip through the cracks.
In SAGAWIT, the goods quality standard usually comes from our client. If they don't, our experts in the related industries will help them establish and improve the necessary quality standard according to the ultimate requirement from the end users.

This standard needs to spell out every key detail that demands your attention, including:
1.What to be inspected
2.How it should be measured
3.The tolerance you allow
4.The illustrated defects description
once finalized, itll serve as the guidance of later production oversees as well as shipment inspections.
Below is an example of the quality standard formulated by SAGAWIT
