Build QC Into the RFQ
Quality control should be part of the RFQ and purchase order, not a last-minute request. The buyer should define which characteristics matter most: dimensions, weight, material grade, color tolerance, logo placement, printing durability, function, accessories, labels, packaging, and carton marks.
A supplier cannot manage quality well if the buyer only says the product should be good quality. Good quality must be translated into observable checks.
Use the Approved Sample Correctly
The approved sample should be stored and referenced during production. If the sample is only a design idea and not made with production material or production process, the buyer should clearly mark which parts are for reference only.
For custom products, many disputes happen because the buyer thinks the sample represents one thing while the supplier thinks it represents another.
Plan In-Process and Final Checks
In-process checks are useful when the order has new material, color matching, printing, assembly, or packaging risk. They catch problems before all units are finished.
Final inspection checks the finished goods against the approved sample, order specification, packaging rules, and carton marks. It should happen before balance payment and before shipment release whenever possible.
Check Packaging as Part of Quality
Packaging is not only a shipping detail. For retail or private label orders, packaging errors can make otherwise good products unsellable.
Buyers should check barcode, label position, language, warning statements, insert cards, carton marks, master carton quantity, and export packing strength.
Define Defect Levels Before Inspection
Buyers should define which issues are critical, major, and minor before inspection. Critical defects may affect safety, legal sale, function, or customer use. Major defects may affect brand presentation, product value, or sellability. Minor defects may be cosmetic issues that do not block shipment if they stay within tolerance.
This prevents inspection disputes. If the buyer and supplier do not agree on defect levels in advance, the same issue may be treated as acceptable by the factory and unacceptable by the buyer.
Create a Shipment Decision Rule
A final inspection should lead to a clear decision: ship, sort, rework, replace, discount, or hold. Buyers should decide in advance what happens when defects exceed tolerance or when packaging is wrong.
For custom products, time pressure can push buyers to accept weak goods before a launch or event. A written shipment decision rule helps the buyer protect the brand and gives the supplier a clear correction path.
