We arrange samples from Chinese factories, compare them against the agreed requirements and document the finished goods before shipment.

Before paying for a production run, it is important to test more than appearance. We define the relevant material, dimensions, functions, colour, contents, packaging and acceptable tolerances.
For a finished order, we compare the available goods with the approved sample or specification. Findings are recorded through photos, video or an inspection report within the agreed scope and sampling method.

Materials, workmanship, function, contents and packaging quality.
Quantity, visible condition, sampled units, markings and cartons before dispatch.
Record non-conformities and discuss possible rework before the goods leave China.
A control point
Build a checklist from the specification, reference or approved sample.
Confirm the date, product readiness and inspection format with the factory.
Record findings, deviations and decision-critical details.
You decide whether to accept, request correction or inspect again.
YANGO GROUP
Quality control reduces risk but cannot make manufacturing completely variance-free. We define the scope and limits of the check before it takes place.
FAQ
Clear answers before the work begins.
Yes. We can receive samples from multiple suppliers, record and compare them, then consolidate them into one international shipment.
No. A sample-based inspection is not an absolute guarantee. It reduces risk and reports the state of the accessible goods against agreed criteria and sampling.
Check samples before mass production and inspect finished goods after production but before logistics handover. Complex projects may need in-process checks.
Check before shipment
Describe the product and the points that matter. We will suggest an appropriate control format and scope.
