Vape Cartridge audit and factory check — a quick reference
There is no shortage of suppliers quoting vape cartridge. The scarce thing is a supplier who will tell you which SKU to drop. We have been shipping vape cartridges long enough to know that the honest answer is usually a shorter list, and that is the answer we give.

Reading a quotation properly
We work with first-time buyers who order between a few hundred and a few thousand units at a time, and we treat both ends the same way: a written specification, a sample you approve, and a production run that matches the sample.
Freight is quoted separately and honestly. Bundling it into the unit price looks tidy and hides the one line that changes most often between shipments.
The cheapest way to lower your cost per unit is usually to remove a SKU, not to negotiate a discount. Fewer lines means larger runs, fewer changeovers and a better price at the same quality.
What a sensible opening order looks like
We source vape cartridges from a small group of factories we have worked with for years. That means a specification can be held across repeat orders instead of being re-qualified from scratch every quarter. Consistency is a boring selling point and it is also the entire game.
Factory capacity matters more than factory size. A line that can hold a tolerance across 5,000 units is worth more than a showroom that can produce 50,000 on paper. We qualify capacity by running a repeat order and measuring the drift.
Quality control, in plain terms
Every batch is pulled from running production, not from a display shelf. We check draw resistance, airflow balance, charge behaviour, leak performance after a temperature shift, finish quality and carton integrity, and we keep the pull records against the order number.
Cosmetic grading is written down, not argued about. Minor scuffs inside the tolerance band are accepted; anything that would make a customer put the unit back on the shelf is rejected. Your staff should never have to explain a finish defect to a paying customer.
- Specification locked in writing before production starts
- Seven-day defect reporting with replace-or-credit
- Reference sample retained from every batch
- Mixed SKU cartons to spread first-order risk
- Batch codes traceable from carton back to production date
- Standing reorder schedule with a fixed cut-off
What happens when something goes wrong
For private label accounts we hold the artwork files and the approval record. Rebranding a line eighteen months later is then a file update instead of a redesign.
Every account gets a named contact who has actually seen the product. Being passed between three people to answer one question about a coil resistance is the fastest way to lose a buyer, so we do not organise support that way.
Specification summary
| Volume | 1.0 ml |
| Core | Mesh |
| Resistance | 1.5 ohm |
| Thread | 510 thread |
| Airflow | Side |
| Packaging | Blister |
| Minimum order | 50 units per SKU, mixed cartons allowed |
| Lead time | 25 working days after artwork approval |
None of this is complicated. It is just written down, which is more than most buyers get before they wire a deposit.
Frequently asked
What documents come with a shipment?
Commercial invoice, packing list, and the certificate pack for your market: test reports, declaration of conformity and safety data sheets. We send scans before dispatch so your broker can pre-clear the file.
Can we order samples before committing?
Yes. Sample orders are shipped by air express and the cost is credited against your first production order above 500 units. We would rather you handle the sample than approve a specification from a photograph.
Do you support private label?
We do. Send your artwork or your brand direction and we will return a digital proof, then a physical dummy for colour approval. Packaging files stay on record so a rebrand later is a file update rather than a redesign.
