The During Production Inspection (DUPRO or DPI), or In-line Product Inspection (IPI), checks semi-finished or finished goods part-way through the production process. Generally, this takes place when between 40% of your order has been produced and 20% export-packed.
Doing so improves your control over production and allows for timely correction of defects and improvements to quality.
