Vape Cartridge QC steps: notes
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.

Assortment planning without the guesswork
Vape Cartridge sits in a crowded price band, and the cheapest quote on the sheet is rarely the cheapest unit on your shelf. Everything below is built around reorder rate, defect rate and cash conversion rather than headline unit price.
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.
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.
Where defects actually come from
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.
We photograph the packing station during production for volume orders. It is a small thing, but it settles most arguments about what was actually in the carton before it was sealed.
Shipping without surprises
Damage in transit is nearly always a packing decision, not bad luck. Double-walled cartons, internal dividers and a drop-tested configuration cost a little more and save the argument at the other end.
Freight on vape cartridges is driven by volume more than weight. Cartons are designed to hit a clean pallet count, which is why a slightly denser pack can cut your landed cost by more than a discount on the unit price ever would.
- Named account contact who has handled the product
- Reference sample retained from every batch
- Seven-day defect reporting with replace-or-credit
- Standing reorder schedule with a fixed cut-off
- Artwork proof plus physical dummy for custom packaging
- Batch codes traceable from carton back to production date
Unit price versus landed cost
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.
We publish a realistic band of 1.82 to 5.58 per unit for standard configurations at 240 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.

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 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.
What is the minimum order for vape cartridge?
Standard configurations start at 240 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 600 units because of setup time on the line.
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 240 units. We would rather you handle the sample than approve a specification from a photograph.
