Sourcing THC Vape: sample testing protocol deep dive
If you are comparing three quotes for THC vape, compare the paperwork first. Test reports, artwork files, batch coding and the replacement clause tell you more about a supplier than the unit price on page one.

Building an assortment that actually turns
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.
We keep a short list of approved configurations for THC vape products. Anything outside that list is possible, but it becomes a custom run with a custom lead time, and we quote it as such rather than pretending everything is standard.
A practical starting order for online vape stores is 500 units across two or three SKUs, not 500 units of one. That spreads the risk, gives your staff something to compare, and still hits the first price break.
The reorder is the real test
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.
Technical questions usually arrive at the worst possible moment, which is why we answer them on WhatsApp as well as email. A photo and a two line message resolves most issues faster than a ticket.
Price breaks and payment terms
The cheapest way to lower your cost per unit is usually to remove a SKU, not to negotiate a discount. Fewer lines means larger runs, fewer changeovers and a better price at the same quality.
We publish a realistic band of 3.44 to 9.62 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.
- Seven-day defect reporting with replace-or-credit
- Document pack prepared per destination market
- Specification locked in writing before production starts
- Reference sample retained from every batch
- Artwork proof plus physical dummy for custom packaging
- Standing reorder schedule with a fixed cut-off
Batch consistency and why it matters
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.
Every batch is pulled from running production, not from a display shelf. We check draw resistance, airflow balance, charge behaviour, leak performance after a temperature shift, finish quality and carton integrity, and we keep the pull records against the order number.
Specification summary
| Volume | 1.0 ml |
| Hardware | Cotton core |
| Thread | 510 thread |
| Airflow | Fixed |
| Window | Full glass |
| Packaging | Tube |
| Minimum order | 50 units per SKU, mixed cartons allowed |

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
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.
What is the minimum order for THC vape?
Standard configurations start at 500 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 1000 units because of setup time on the line.
