As Vibrelli says, I use an extra step where the freight forwarder quality check every item before sending them to Amazon.

How does that work? Do they open 1 in 10, 1 in 100, etc.? Are products sealed at the factory? Or does the freight forwarder seal them for you?

They open and repack everything. Amazon requires a specific Amazon barcode, you can either pay them to do it for you for 20c an item or pay someone else to do it. I found I could get the item quality checked and barcoded for the same price as Amazon would do it.

Great answer, thanks! So quality check is 100%? And what is the defect rate? What happens when a defective product is found?
