If you purchase products from an overseas supplier that you don't know well, and you can't be there, you might want to contact an inspection agency to handle inspecting product quality on your behalf. But you need to give them direction on WHEN to go to the factory and WHAT to check. I tried to summarize it in this flow chart: Here are some suggestions for your inspection options for the scenarios that apply to many importers' situations when inspecting product quality that you can … [Read more...]
3 Examples of Quality Inspection Checklists
Over the years, we have provided feedback to many clients on their product specification sheets and their inspection checklists. Rather than a step-by-step guideline, the most useful is usually to provide them with a few real examples for different types of products. 3 examples of inspection checklists Last year, when personal protective equipment was severely lacking in many countries, we released some of our templates on our commercial website.

Understanding Product QC Inspections: What Is in a Man-Day?
A conversation earlier today made me realize that some buyers who haven’t spent much time in Chinese factories have some common misconceptions. For example, “Chinese production operators are forced to work 12 hours a day, in a case of modern slavery”, “all metal factories do all the steps from casting/forging to surface treatments and all the way to assembly and packing”, and so on. Another misconception is that a good inspector will spend 8-10 hours working at the factory. This is what I … [Read more...]
From Data Science To Machine Learning in Manufacturing, for Smarter Quality Control
I have long been put off by all the hype around artificial intelligence (AI). AI has become the modern 'magic wand': nobody knows how it works, but the results are assuredly amazing. AI has limitations for manufacturers, but both data science and machine learning in manufacturing can help businesses make better decisions and improve quality control results, and it's these that we'll explore in this article... … [Read more...]
Traceability in Manufacturing: Do your Chinese Suppliers Do it Right?
I see buyers who spend a lot of time pushing their suppliers to do QC inspections on incoming components, to keep the production area clean, to give clear instructions to operators, and other basics. But I seldom hear them push for traceability in manufacturing, despite how important it is. I thought I should write about it again. … [Read more...]
Managing QC Inspectors, Part 8: QC vs. QA

They should not take decisions, in order to reduce risks of bribery. Similarly, they should not try to solve the problem with the factory. The … [Read more...]
Managing QC Inspectors, Part 7: The Quality Manager in China
This is the seventh part in the series I am writing about the management of QC inspectors in China. Many companies in China have difficulties finding the right quality manager. In particular, it is difficult to find an individual who will simultaneously: Run the day-to-day operations of the quality department and repeat the same principles to his staff and to suppliers 10 times a day -- and keep doing this for years; Be a change agent and guide his/her team to work in a different way (from … [Read more...]
Managing QC Inspectors, Part 6: Planning the Inspections
This is the sixth part in the series about the management of QC inspectors in China. In my last article on this topic, I mentioned the need to have system to manage the planning. Some companies let factories and inspectors set the planning freely among themselves, and I think that's a big mistake. Here is the advice I usually give buying offices. 1. Manage the planning in the office An assistant manager should set the planning. Suppliers should send an application (for example every … [Read more...]
Managing QC Inspectors, Part 5: Avoiding Bribery
This is the fifth part in the series about the management of QC inspectors in China. I touched on the evaluation of quality inspectors, and it naturally brings up the topic of bribery. How big of a problem is corruption of inspectors in China? In many developing countries, people in a position of authority, and to a lesser degree those who report information for use by decision makers, are prone to corruption. It happens in Mexico, in China, in Bangladesh, in Egypt, and in many other … [Read more...]
