Choosing THC Vape coil supply with COA
We work with wholesale buyers 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.

Where defects actually come from
There is no shortage of suppliers quoting THC vape. The scarce thing is a supplier who will tell you which SKU to drop. We have been shipping THC vape products long enough to know that the honest answer is usually a shorter list, and that is the answer we give.
A 0.5 percent defect rate sounds excellent until it lands on a 600 unit order and you are handling three returns in a week. We quote realistic rates per category and we credit in advance for the known failure modes.
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.
Getting the carton there intact
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.
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.
The reorder is the real test
For private label accounts we hold the artwork files and the approval record. Rebranding a line eighteen months later is then a file update instead of a redesign.
We keep the specification sheet for every order on file. Two years later, when a customer asks whether a pod is compatible, the answer is a lookup rather than a guess.
- Reference sample retained from every batch
- Standing reorder schedule with a fixed cut-off
- Named account contact who has handled the product
- Batch codes traceable from carton back to production date
- Cartons drop-tested and pallet-counted for clean freight
- Specification locked in writing before production starts
Building an assortment that actually turns
A practical starting order for wholesale buyers is 200 units across two or three SKUs, not 200 units of one. That spreads the risk, gives your staff something to compare, and still hits the first price break.
Sourcing trips still matter for volume buyers. Seeing the line, the ageing room and the packing station tells you in an hour what six emails cannot. We host visits by appointment and we do not stage them.
Specification summary
| Volume | 0.5 ml |
| Hardware | Ceramic core |
| Thread | 510 thread |
| Airflow | Fixed |
| Window | Side window |
| Packaging | Tube |
| Minimum order | 50 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
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.
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.
What happens if part of the order is defective?
Report within seven days with photos and the batch code. Confirmed defects are replaced or credited on the next shipment. The failure is logged by mode and batch, and reviewed monthly with the factory.
