What happens when a Chinese manufacturer replaces an approved component or material without telling the buyer? The product might look identical and pass basic inspections, but hidden substitutions can lead to premature failures, compliance problems, and even safety risks.
In this episode of China Manufacturing Decoded (Ep. 352), Sofeast’s Adrian Leighton and Renaud Anjoran discuss why factories make unauthorized component substitutions, how importers can detect them, and what to do when products have already been manufactured using unapproved materials or components.
Not every unauthorized change is deliberate dishonesty. Misunderstandings about specifications, pressure to reduce costs, and poor communication can all contribute. However, some suppliers deliberately downgrade materials to improve their margins, a practice known as quality fade. Understanding the difference and putting appropriate controls in place is essential for protecting product quality and reliability.
