PSI FAQs
Learn more
Are packing items photographed?
Yes. Cartons, tags, polybags.
How do I decide if the goods are accepted?
Read our detailed report. We show you the defect percentage, and the final decision (Pass/Fail for the manufacturer) is always yours.
Does it help if I did DPI or PPI before?
Definitely. Products have far fewer defects, and the chance of a Fail status at PSI is minimal if problems were fixed early.
