Vape Cartridge factory audit checklist — a explained
If you are comparing three quotes for vape cartridge, compare the paperwork first. Test reports, artwork files, batch coding and the replacement clause tell you more about a supplier than the unit price on page one.

Where defects actually come from
We work with B2B 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.
Flavour drift between batches is the quiet killer of repeat orders. We retain a sealed reference sample from every run so a complaint six weeks later can be compared against what actually left the building.
Leak complaints almost always trace back to one of three things: an over-torqued centre post, a seal that sat in a hot container, or a fill volume pushed past the design limit. We cap fill volume slightly below maximum for exactly that reason.
Building an assortment that actually turns
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.
Colour range is where assortments quietly die. Six finishes look impressive in a brochure and disastrous on a shelf with 40 cm of space. We recommend two finishes per core SKU and let the trial line carry the novelty.
The reorder is the real test
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.
We keep the specification sheet for every order on file. Two years later, when a customer asks whether a pod is compatible, the answer is a lookup rather than a guess.
- Artwork proof plus physical dummy for custom packaging
- Consolidated or split shipping, quoted both ways
- Specification locked in writing before production starts
- Reference sample retained from every batch
- Private label files archived for future rebrands
- Seven-day defect reporting with replace-or-credit
Reading a quotation properly
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.
We publish a realistic band of 1.82 to 5.74 per unit for standard configurations at 500 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.
Specification summary
| Volume | 0.5 ml |
| Core | Cotton |
| Resistance | 1.8 ohm |
| Thread | Press-fit |
| Airflow | Side |
| Packaging | Blister |
| Minimum order | 300 units per SKU, mixed cartons allowed |
| Lead time | 30 working days after artwork approval |
We would rather lose an order at quotation stage than explain a mismatch after delivery, which is why the specification conversation comes before the price conversation.
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.
How long does production take?
Around 28 working days after artwork approval for stock configurations, plus transit. Custom runs add roughly a week for tooling and a physical dummy. We confirm the date in writing on the order acknowledgement.
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.
