How to source THC Vape certification with COA
We work with dropshippers 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.

Simple habits that lift velocity
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.
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.
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.
Unit price versus landed cost
Custom printing raises the unit price and lowers the marketing cost. For dropshippers the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.
We publish a realistic band of 3.49 to 9.35 per unit for standard configurations at 500 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.
Labels, closures and traceability
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.
We keep batch codes traceable from carton to production date. When a market authority asks for traceability, a supplier who cannot produce it in an hour becomes a liability very quickly.
- Seven-day defect reporting with replace-or-credit
- Cartons drop-tested and pallet-counted for clean freight
- Standing reorder schedule with a fixed cut-off
- Specification locked in writing before production starts
- Reference sample retained from every batch
- Consolidated or split shipping, quoted both ways
Choosing the core line
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.
The first question we ask is not what you want to spend. It is what your customer already buys. Answer that and the THC vape list writes itself; skip it and you end up with a pallet of stock that photographs well and sells badly.
Specification summary

| Thread | Proprietary pod |
| Airflow | Adjustable |
| Window | Full glass |
| Packaging | Tube |
| Minimum order | 300 units per SKU, mixed cartons allowed |

None of this is complicated. It is just written down, which is more than most buyers get before they wire a deposit.
Frequently asked
How long does production take?
Around 18 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.
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.
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 500 units. We would rather you handle the sample than approve a specification from a photograph.
