Choosing Vape Coil aging and leak tests
A vape coil programme only works when three numbers agree: your shelf price, your reorder cycle and your defect tolerance. Change one and the plan moves. We build assortments around those three and we say so up front rather than after the invoice.

Building an assortment that actually turns
There is no shortage of suppliers quoting vape coil. The scarce thing is a supplier who will tell you which SKU to drop. We have been shipping vape coils long enough to know that the honest answer is usually a shorter list, and that is the answer we give.
Most first-time buyers arrive with a spreadsheet and leave with too many SKUs. The fix is not a bigger catalogue, it is a narrower core. We normally propose three tiers: a volume line that carries the shelf, a step-up line that lifts basket value, and one trial SKU that tells you what to order next season.
Sourcing trips still matter for volume buyers. Seeing the line, the ageing room and the packing station tells you in an hour what six emails cannot. We host visits by appointment and we do not stage them.
Where the margin really sits
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 0.57 to 2.40 per unit for standard configurations at 300 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.
What your market will ask for
Artwork approval is a two stage process: a digital proof for text and layout, then a physical dummy for colour and finish. Skipping the dummy is the single most common cause of a reprint.
If you sell into a market that requires child-resistant packaging, say so at quotation stage. Retrofitting a CR closure onto a finished bottle design usually means a new mould and a four week delay.
- Standing reorder schedule with a fixed cut-off
- Artwork proof plus physical dummy for custom packaging
- Named account contact who has handled the product
- Consolidated or split shipping, quoted both ways
- Reference sample retained from every batch
- Batch codes traceable from carton back to production date
The checks behind every shipment
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.
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.
Specification summary
| Resistance | 0.20 ohm |
| Build | Clapton |
| Wicking | Organic cotton |
| Fitment | Threaded |
| Pack size | 3 per pack |
| Compatibility | Universal deck |
| Minimum order | 50 units per SKU, mixed cartons allowed |
| Lead time | 18 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 happens if part of the order is defective?
Report within seven days with photos and the batch code. Confirmed defects are replaced or credited on the next shipment. The failure is logged by mode and batch, and reviewed monthly with the factory.
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.
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.
