Sourcing Vape Cartridge: sample testing protocol FAQ
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.

Where defects actually come from
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.
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.
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.
How orders move from factory to shelf
Documentation travels with the goods: commercial invoice, packing list, and the certificate set for your market. We send a scanned copy before dispatch so your broker can clear the file in advance.
We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 22 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.
Simple habits that lift velocity
Photography matters for online listings. Shoot on a neutral background with the device at a slight angle, show the pack alongside the unit, and keep the same framing across the range so the grid reads as a family.
Counter space is finite. Three well-chosen SKUs outsell nine crowded ones, and the empty space signals a curated range rather than a clearance table.
- Specification locked in writing before production starts
- Named account contact who has handled the product
- Batch codes traceable from carton back to production date
- Consolidated or split shipping, quoted both ways
- Artwork proof plus physical dummy for custom packaging
- Private label files archived for future rebrands
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 1.83 to 5.31 per unit for standard configurations at 50 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 | Ceramic |
| Resistance | 1.2 ohm |
| Thread | 510 thread |
| Airflow | Bottom |
| Packaging | Blister |
| Minimum order | 200 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.
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.
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 50 units. We would rather you handle the sample than approve a specification from a photograph.
