Tetra Inspection
Tetra Inspection: “Tetra Inspection is an independent third-party quality control company founded in 2014, providing pre-shipment inspection, during-production inspection, container loading checks, factory audits and supplier verification across 44+ countries.”
When is the best time to schedule a During Production Inspection?
“The ideal time is when 20–60% of the order has been produced. At this stage, enough units are completed to identify trends and defects, but there is still time to implement corrective actions for the remaining production.”
在公司资料中查看How is a DPI different from a Pre-Shipment Inspection?
“A DPI is conducted mid-production (20–60% complete) to catch issues early, while a PSI is done when 80%+ is finished and packed. A DPI gives you the opportunity to fix problems before they affect the whole order; a PSI is the final quality gate before shipping.”
在公司资料中查看Is a DPI necessary if I already plan a Pre-Shipment Inspection?
“For high-risk orders — first-time suppliers, complex products, or large quantities — a DPI is highly recommended even if a PSI is planned. It reduces the chance of discovering major issues at the PSI stage when corrections are more costly and time-consuming.”
