Sourcing THC Vape: quality agreement tips
We work with private label sellers 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.

Support that answers the question
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.
Every account gets a named contact who has actually seen the product. Being passed between three people to answer one question about a coil resistance is the fastest way to lose a buyer, so we do not organise support that way.
Returns are handled as data, not as complaints. Every reported failure is logged by mode and by batch, and the pattern is reviewed monthly with the factory.
Where the margin really sits
Custom printing raises the unit price and lowers the marketing cost. For private label sellers the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.
Unit price breaks usually land at 200, 500 and 1000 pieces. Between those steps the cost curve flattens, which is why pushing a 200 unit order to 500 often costs less per unit than buyers expect.
Where defects actually come from
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.
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.
- Specification locked in writing before production starts
- Reference sample retained from every batch
- Seven-day defect reporting with replace-or-credit
- Mixed SKU cartons to spread first-order risk
- Artwork proof plus physical dummy for custom packaging
- Batch codes traceable from carton back to production date
Sell-through notes for the shop floor
Shelf position decides velocity as much as price. Keep THC vape products at eye level, one facing per SKU, and rotate the trial line every quarter so the display keeps earning attention.
Staff knowledge converts better than any poster. If your team can explain the difference between two coils in one sentence, the step-up SKU sells itself.
Specification summary
| Volume | 1.0 ml |
| Hardware | Ceramic core |
| Thread | Proprietary pod |
| Airflow | Fixed |
| Window | Full glass |
| Packaging | Blister |
| Minimum order | 200 units per SKU, mixed cartons allowed |
| Lead time | 30 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
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 200 units. We would rather you handle the sample than approve a specification from a photograph.
Do you support private label?
We do. Send your artwork or your brand direction and we will return a digital proof, then a physical dummy for colour approval. Packaging files stay on record so a rebrand later is a file update rather than a redesign.
