How to source Vape Cartridge production with COA
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.

Reading a quotation properly
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.
We publish a realistic band of 1.85 to 5.36 per unit for standard configurations at 200 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.
A landed cost sheet for vape cartridge has five lines: unit price, packaging, freight, duty and the cost of defects. Quoting only the first line is how buyers end up surprised at the fourth.
The reorder is the real test
Technical questions usually arrive at the worst possible moment, which is why we answer them on WhatsApp as well as email. A photo and a two line message resolves most issues faster than a ticket.
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.
What we test before a carton is sealed
Battery safety is not a marketing line. Cells are matched by capacity and internal resistance before assembly, charging boards are checked for cut-off voltage, and any unit that fails the cut-off test never reaches packing.
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.
- Mixed SKU cartons to spread first-order risk
- Artwork proof plus physical dummy for custom packaging
- Private label files archived for future rebrands
- Reference sample retained from every batch
- Consolidated or split shipping, quoted both ways
- Document pack prepared per destination market
What a sensible opening order looks like
We keep a short list of approved configurations for vape cartridges. Anything outside that list is possible, but it becomes a custom run with a custom lead time, and we quote it as such rather than pretending everything is standard.
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.
Specification summary
| Volume | 2.0 ml |
| Core | Mesh |
| Resistance | 1.5 ohm |
| Thread | Press-fit |
| Airflow | Bottom |
| Packaging | Tube |
| Minimum order | 100 units per SKU, mixed cartons allowed |
| Lead time | 18 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
How do you handle repeat orders?
The specification is held on file against your account, so a reorder is a reference rather than a new brief. We recommend a standing schedule with a fixed weekly cut-off so stock lands before the shelf empties.
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.
How long does production take?
Around 25 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.
