I've watched importers vet factories for 15 years. Here's what most of them do:

They scroll through Alibaba listings. They message three suppliers. They compare prices, ask for a sample, and pick the one with the best price-to-sample ratio.

That's not vetting. That's online shopping with extra anxiety.

Over the years, I've developed a simple framework — seven questions that separate real factories from trading companies, reliable partners from time bombs. Every question can be asked over a 30-minute video call. None of them requires leaving your desk.

The Seven Questions

1. Can you show me your mold workshop right now?

This is the single most revealing question you can ask a luggage supplier.

Real factory response: They pick up their phone, walk to the mold workshop, and show you CNC machines, EDM equipment, and molds in progress. Takes 2 minutes.

Trading company response: [object Object] or [object Object] or [object Object].

A luggage factory that doesn't own its mold workshop has zero control over its single most critical timeline variable. Every mold modification goes through a third party. Every delay has a built-in excuse. Every cost has an added margin.

2. What are you producing right now on your main line?

Not 'what can you produce.' Not 'what have you produced.' What's physically on the line today.

If they're running 20-inch carry-ons in ABS and you're ordering 28-inch checked bags in PC, that's not necessarily a dealbreaker — but it tells you exactly what their current expertise is calibrated for.

The best answer: [object Object] And they pan the camera.

If they can't or won't show you live production, there are only two possibilities: they're not a factory, or their production floor doesn't look the way they want you to see it. Neither is good.

3. What's the batch number on your raw material inventory?

This sounds pedantic. It's not.

Go to any factory, walk to their raw material storage, and look at the PC granulate bags. Each bag has a batch number, material grade, and manufacturer marking.

What you're checking: Is it Bayer Makrolon, SABIC Lexan, or a no-name domestic supplier? Is the melt flow index printed on the bag? Does the batch number match what's in the current production run?

A factory that tracks material batch numbers has a traceability system. A factory that doesn't know what batch they're running has no way to correlate material quality with finished product quality. When defects appear, they'll never know why.

4. Who are three of your current clients, and can I speak to one?

Some factories will decline for confidentiality reasons — that's legitimate. But most will give you at least one reference if you're serious.

When you get the reference, don't ask vague questions. Ask these three specifically:

• 'What was the single biggest problem you had with this factory — and how did they handle it?'
• 'If you were starting over, would you choose them again? Why or why not?'
• 'What's one thing about working with them that surprised you — good or bad?'

The answers to these three questions will tell you more than any factory tour.

5. What's your defect rate on the last three orders for [your product type]?

Every factory tracks this internally. Whether they share it with you is a different question.

What you're looking for is not the number itself, but the reaction. A factory that immediately says '1.2% on our last PC carry-on run' has a real QC system. A factory that says 'we don't track that exactly' or 'very low, almost zero' is either lying or not measuring.

Good factories know their defect rates to one decimal place. Great factories can tell you which specific defect type was most common and what they changed to fix it.

6. What happens if my order is delayed?

This is a scenario question, and it's designed to test one thing: does this factory have a contingency plan, or are they making promises they can't keep?

Bad answer: "That never happens. We always deliver on time."

Good answer: "If a delay is caused by a material shortage, we have backup suppliers. If it's a production bottleneck, here's how we re-prioritize. If it's force majeure, here's our communication protocol. In our worst delay in the last 3 years, we were 8 days late on a 2,000-unit order and we absorbed the air freight cost to get 200 units to the client on time."

The difference is the difference between a partner and a vendor.

7. What's one thing you wish more buyers understood about luggage manufacturing?

I love this question. It's disarming, it's open-ended, and it reveals everything about how the factory thinks about the buyer relationship.

Some factories will talk about cost pressures. Others about unrealistic lead time expectations. The best ones will give you a specific, thoughtful answer about the craft — material behavior, design-for-manufacturing, the tension between aesthetics and durability.

You're not just listening to the answer. You're measuring: does this person think like a manufacturer, or like a salesman?

The Red Flag Scorecard

Any one of these isn't fatal. Multiple red flags in combination are.

The bottom line: good factories are easy to vet because they have nothing to hide. The ones that make you work for information are telling you exactly who they are — you just have to listen.
