Buyers often ask what happens during a factory inspection. We walk through a typical during-production and pre-shipment inspection and explain how the findings protect both buyer and supplier.
An order has been placed, samples were approved months ago, and production is under way on the other side of the world. What arrives in the container is what the buyer will sell. Independent inspection is how that buyer finds out, before the goods ship, whether the order matches the agreement.
A production line inspection usually happens in two stages. The during-production inspection takes place when a portion of the order is complete. The inspector checks that the materials, components and processes match the approved specification, that the first finished units meet the agreed quality level, and that the schedule is realistic. Problems found here are still cheap to fix.
The pre-shipment inspection happens when the order is packed and ready. Cartons are selected at random according to a statistical sampling plan, opened, and the contents examined against the specification: appearance, dimensions, function, markings, labelling, packaging and any safety tests that can be performed on site. Defects are classified by severity, and the result is a clear accept, reject or hold decision supported by photographs.
The value of an inspection lies in its independence. The inspector works for neither the buyer's purchasing team nor the factory, and the report says what was found. A good supplier welcomes this, because an independent record protects it from disputes just as much as it protects the buyer.
Reports are only useful if they can be trusted. We issue every inspection report under controlled procedures, and any recipient can confirm through our verification service that a report was issued by us and has not been altered. In a market where reports are sometimes copied and edited, that check takes a minute and can save a great deal.
For buyers new to inspection, the most important preparation is a clear specification. Inspectors can only check against what has been agreed. A precise specification, an approved sample and a defined quality level turn a subjective argument about "good enough" into a measurable result.
