I have written extensively about pre-shipment inspections (before, during, or after production), always from the perspective of the buyer checking what a supplier is doing; but I noticed that I haven't covered receiving inspections (also called incoming quality inspections). However, that's a really important topic, so let's get into how to set one up here... … [Read more...]
21 Assumptions About Buying From Chinese Suppliers To Avoid
Many buyers who are seeking to manufacture products in China tend to make assumptions about buying from Chinese suppliers that are seldom valid here, and it can be quite dangerous. When I started spending a lot of time in Chinese factories, what I saw blew my mind. A foreign buyer simply can’t imagine what is sometimes going on behind the scenes. I'll say that China is the land where everything is possible... from the worst to the best. I wrote 21 common assumptions below, in categories, … [Read more...]
Are Calibration Reports Always A Must? Why Auditors Should Think Before Raising Suppliers’ Costs
By Annie Chan Did you get a visit from an auditor who seemed obsessed with calibration reports? Was he/she happy to see that all tools had been calibrated based on internal reports, or (even better) on third-party lab certificates? There is no doubt auditors love asking for all kinds of reports to confirm the supplier complies with requirements. However, their requests are not always reasonable. … [Read more...]
How Much Does a Quality Inspection in China cost?
Understanding the cost of quality inspections in China I am always surprised by the expectations of some importers regarding the cost of quality inspections in a Chinese factory. Some importers get to talk about their project for some time, see where we would help them, and finally (almost as an afterthought) ask: "How much does a quality inspection in China cost?" The 2 categories of buyers when it comes to quality inspection costs I say "299 USD per day of work", and I can nearly hear … [Read more...]
When To Do a Random AQL Inspection vs. Check 100% of the Goods
First, let me get one thing out of the way: not all batches need to be checked. If a manufacturer has great systems and processes, and if they have a history of complying with your quality standard, there is usually no reason to send quality inspectors to their facility. Similarly, if you can easily return the whole batch and it can be reworked quickly, you probably don't want to spend resources on checking whether they did as promised. Now, let's assume you do want confirmation of … [Read more...]
3 Common Ways Factories Try to Cheat Inspectors/Auditors
Every day in China, in Vietnam, in Bangladesh, and in India, thousands of inspectors and auditors take a bus or a car to a factory. And, in some of those factories, managers are plotting how to cheat those unwelcome visitors. Let's look at 3 very common ways this is done, so you are warned and ready to avoid unscrupulous suppliers like this... … [Read more...]
Chinese Factories Designing, Branding, and Selling on Amazon: Q&A
I wrote before about the challenges of Chinese factories to sell on Amazon. And yet, it seems to be an emerging trend. I asked Fredrik Gronkvist (from China Importal), who has also been observing the latest trends, for his opinion on this. Q: Ten years ago, Chinese factories ‘made to order’, and seeing one of them ‘make to stock’ was a rare occurrence. Have you seen more and more manufacturers 'make to stock’? What do they do with it? First, Chinese manufacturers still ‘make to order’ and I … [Read more...]
Solving a Quality Problem Seldom Necessitates High-Tech Engineering
In many companies, and in particular in many Chinese companies, the response to problems is often "let's invest in technology". Unfortunately, spending a lot of resources on engineering is seldom the best solution. I just read a great story that illustrates this. A toothpaste manufacturer had a regular quality issue that was generating bad publicity: some boxes didn't contain a tube of toothpaste. It was due to the way the production lines were set up. They spent 8 million dollars on a … [Read more...]
Defect List vs. Checkpoint List
I noticed many people confuse two things: the list of potential defects, and the list of checkpoints to follow during an inspection. What I see very often is a list of potential defects, but no list of checkpoints. There are 2 main problems with this: The inspector has no structure to follow. When random sampling is used, the inspector should NOT count every problem he finds as a defect. If he checks a point on the full sample size (for example on 200 pcs), that's fine. But this is … [Read more...]
Why the AQL tables are not in favor of the buyer
This is the third and last video about the ANSI tables (also known as “AQL tables”). As I explained in the last video, these sampling schemes were designed for very stable relationships, where the manufacturer keeps making the same products and keeps shipping them regularly (e.g. twice a month) to the same customer. As a consequence, the assumption is that quality is under control. And an inspection is used to catch the big accidents. What it means is that the statistics are way, way … [Read more...]
