Sourcing THC Vape: quality control steps guide
THC Vape 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.

Getting the carton there intact
We work with online vape stores 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.
Transit times move with the season. Book space early for Q4 and around Chinese New Year, when factory output pauses for two to three weeks and freight rates tighten at the same time.
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.
Sell-through notes for the shop floor
Seasonality in THC vape products is real but smaller than most buyers assume. The bigger swing comes from restocking discipline, not from calendar events.
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.
The checks behind every shipment
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.
11 separate checks run before a carton is sealed: electrical, mechanical, leak, finish and packaging. Anything outside tolerance is quarantined the same day and reported to you, rather than shipped with a hope and a discount.
- Cartons drop-tested and pallet-counted for clean freight
- Specification locked in writing before production starts
- Batch codes traceable from carton back to production date
- Standing reorder schedule with a fixed cut-off
- Consolidated or split shipping, quoted both ways
- Reference sample retained from every batch
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 3.47 to 9.56 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 | 1.0 ml |
| Hardware | Ceramic core |
| Thread | 510 thread |
| Airflow | Fixed |
| Window | Side window |
| Packaging | Child-resistant box |
| Minimum order | 50 units per SKU, mixed cartons allowed |
| Lead time | 12 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
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.
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.
Can you ship to multiple locations?
Yes. Split shipments are quoted separately because consolidation and splitting price differently. Tell us the destination list at quotation stage and we will show both options.
