Many buyers worry: Are you working with a real CO2 cartridge factory—or just a trader hiding behind polished photos?
You can quickly verify if a supplier is a real factory by checking their production videos, process knowledge, customization capability, genuine certifications, and delivery reliability.

This checklist reflects what I’ve learned over years of vetting CO2 cartridge suppliers. It helps you avoid unreliable traders and partner with a factory that delivers quality, customization, and consistency.
Is there a real production video or factory tour available?
Pictures can be fake—only a factory video gives real proof.
A genuine factory can show you their production line in action—machinery, staff, testing—whereas a trader usually only shares showroom photos.
Why a video matters:
- It shows real machinery—cutting, welding, testing stations.
- You’ll see staff in uniforms, assembly lines in motion.
- If they only show showrooms or marketing photos, it’s a red flag.
How to spot authenticity:
- Look for continuous conveyor belts or automated production equipment.
- Watch for welding units, leak-test benches, spray booths in use.
- Observe if workers handle raw material to finished cartridge steps.
If the supplier hesitates or only sends staged images, they’re likely a trader.
Can they explain their full production process?
Ask for details—you’ll soon know if they’re familiar with their own operations.
A real manufacturer knows every step: cutting, welding, testing, painting, valve assembly. A trader struggles to explain these clearly.
Here’s a typical CO2 cartridge production table:
| Process Step | Description |
|---|---|
| Cutting Steel Tube | Precision cutting of raw tubes |
| Welding | Bottle body formed by welding |
| Leak Testing | 100% pressure leak test |
| Spray Painting | Surface finish (color, coating) |
| Valve Assembly | Attaching and sealing valve system |
Ask these:
- What welding machine models do you use?
- What is your daily output capacity?
- Do you test every cartridge automatically?
Fumbling or vague answers usually point to a trading company that outsources manufacturing.
Do they offer genuine customization or just standard SKUs?
“Customization” can just be a buzzword—only a factory can truly deliver it.
Real factories offer customization—in logos, packaging, thread specs, colors, even food-grade variants. Traders stick to standard stock models.
Compare capabilities:
| Customization Feature | Genuine Factory | Trader |
|---|---|---|
| Silk‑printed Logo | Yes | Maybe via outsourcing |
| Custom Packaging | Yes | Often outsourced |
| Thread Size Variation | Yes | No |
| Food‑grade Certification | Yes | Possibly no |
| Non‑standard Sizes | Yes | No |
Test them: “Can you produce an 18g CO2 cartridge with 5/8″ thread and yellow coating?” Their response will speak volumes.
Can they share certification documents with factory info?
Certs are your remote verification tool—demand them.
A genuine factory provides ISO, CE, UN, or food-grade docs with their name and address. Traders may share misleading or unrelated certificates.
Here’s what to check:
- ISO 9001 should list the manufacturer’s company name and address.
- CE or food‑grade certificates must match the factory’s details.
- Ask for SGS reports, burst‑pressure tests, or leak‑test records.
- Be cautious: some traders use “partner factory” documents to mislead.
Ask them to upload certs to a public registry, or verify their manufacturing status on Alibaba.

How consistent and fast are their delivery times?
Reliable factories ship on time. Traders lag when it matters.
Consistent delivery—sample in a few days, mass production within 1–2 weeks—is a hallmark of a real factory. Traders struggle to meet deadlines.
Typical lead times:
- Sample production: 3–5 days.
- Bulk order: 7–15 days.
- Export documents: 1–2 days.
Ask:
- Can you ship 100,000 cartridges monthly?
- How do you manage peak‑season demand?
- Do you hold safety stock?
If they answer clearly and specifically, they likely run their own production. Vague or evasive answers are suspect.
Conclusion
By verifying factory video, process knowledge, true customization, genuine certifications, and delivery speed, you can confidently avoid traders and partner with a real CO2 cartridge manufacturer.
