Sourcing THC Vape: quality control steps walkthrough
A THC vape 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.

Lead times, freight and landed cost
We work with importers 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.
We can consolidate mixed orders of THC vape products into one shipment. Consolidation saves freight but adds handling days, so we quote both a consolidated and a split option and let you choose.
Choosing the core line
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.
When you compare suppliers for THC vape, ask for the last three production dates on the same SKU. If the answers are vague, the specification is not being held and the next batch will not match the sample you approved.
Reading a quotation properly
A landed cost sheet for THC vape 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.
We publish a realistic band of 3.22 to 9.53 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.
- Standing reorder schedule with a fixed cut-off
- Consolidated or split shipping, quoted both ways
- Document pack prepared per destination market
- Mixed SKU cartons to spread first-order risk
- Named account contact who has handled the product
- Cartons drop-tested and pallet-counted for clean freight
Batch consistency and why it matters
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.
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.
Specification summary
| Volume | 1.0 ml |
| Hardware | Cotton core |
| Thread | Proprietary pod |
| Airflow | Adjustable |
| Window | Full glass |
| Packaging | Tube |
| Minimum order | 200 units per SKU, mixed cartons allowed |
| Lead time | 25 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
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.
How long does production take?
Around 22 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.
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.
