Supplier Risk
Quality Fade in China: Why Your Third Order Has More Defects Than Your First
The first order from a new supplier is often excellent. The second is fine. By the third or fourth, small things start to change: the metal is a little thinner, the coating a little lighter, the carton a little weaker. None of it is announced. This pattern is often called quality fade. It is rarely fraud. It is a factory reducing cost one small step at a time, assuming each step is too small to matter. This guide explains how it happens and how buyers can stop it.

- Where suppliers usually cut first
- How a reference sample and a written specification freeze quality
- Why repeat inspections stop the drift
Why It Happens
A factory prices the first order to win the business. Then costs move: raw material prices rise, wages rise, the currency shifts. The price agreed with the buyer stays the same. The factory looks for savings, and the easiest savings are in places the buyer is unlikely to check. Each change seems small. Together they add up to a different product.
Buyers often make it easier without meaning to. After two good orders, trust grows and checks are dropped. The specification may never have been written down in detail, so the factory can tell itself it is still meeting it. The term "quality fade" was popularised by Paul Midler in his book on manufacturing in China, and buyers in many industries will recognise the pattern.
Where Suppliers Cut First
- Materials. Thinner sheet or wall thickness, a lower steel grade, recycled material mixed into virgin plastic, a cheaper fabric. Our case study on a steel grade substitution describes one real example.
- Invisible process steps. A shorter heat treatment, one coat of paint instead of two, less plating, a skipped polishing step.
- Components. A different motor, switch, bearing or capacitor that looks the same but is not the approved part.
- Packaging. Double-wall cartons replaced with single-wall, thinner inner protection, fewer dividers.
- Internal quality control. Units that would have been reworked or scrapped are packed with the good ones.
Freeze the Standard
Quality fade works when the standard is vague. The fix starts with making it precise.
- Seal a reference sample. Keep an approved sample yourself, and keep a matching sealed sample with your inspector or at the factory, signed and dated. A sample kept only at the factory can age, get lost or be replaced. More on sample approval is in our guide to inspection checklists and sample approval.
- Write the measurable things down. Material grade and standard, thicknesses, weights, coating thickness, component makes and models, carton grade. "Same as sample" is not enough on its own, because many of these cannot be seen.
- Require approval for changes. State in the purchase order that any change of material, component, process or sub-supplier needs the buyer's written approval first.
Keep Checking, and Keep the Records
The most effective deterrent is a supplier knowing that every order will be checked against the same standard. Keep the measurement checks in every pre-shipment inspection, not just on the first order: weights, thicknesses, coating readings, component checks, carton grade. Then compare the readings from order to order. A slow trend, such as average weight falling a little each order, is quality fade showing in the data before customers notice it.
For new suppliers or after a price negotiation, an initial production check confirms the materials and components at the start of the run, when a change is still cheap to reverse. Ask your inspector to record the same measured points each order, so trends show up in the reports. See our inspection services.

SSTI checks every order against the same reference sample and measured points, so changes show up before customers notice.
