Tetra Inspection operates across 45+ countries with a network of certified local inspectors. Our primary coverage includes China, India, Vietnam, Turkey, Bangladesh, Thailand, Indonesia, Morocco, Pakistan, and many more manufacturing regions worldwide.
We deliver detailed, photo-documented inspection reports within 24 hours of the inspection. Reports include defect classification (critical, major, minor) following AQL standards, measurement data, functional test results, and a clear pass/fail verdict to help you make informed shipping decisions.
AQL (Acceptable Quality Limit) is the internationally recognized sampling standard defined in ISO 2859-1. It determines how many units to inspect from a production lot and the maximum number of defects acceptable for the shipment to pass. Tetra Inspection uses AQL-based sampling for all product inspections to ensure statistically reliable results.
A product inspection evaluates the quality of finished or in-progress goods against your specifications. A factory audit assesses the supplier's manufacturing capabilities, quality management systems, working conditions, and compliance with industry standards. Factory audits help you qualify new suppliers, while product inspections verify each shipment meets your quality requirements.
