Why third party inspection (TPI) is required?

Most companies consider third-party inspections a well-justified expense. They are performed by companies with a strong expertise, working on the ground every day. They provide a neutral opinion on the goods quality and allow to keep a close eye on quality consistency on site without having to be there. This way, the buyers are fully aware even at distance, of the manufacturing process, and can build a confident relationship with the supplier. Moreover, despite coming at a cost, TPIs end up saving you money by helping avoid expensive errors or employing an in-house QC team.
