Sourcing THC Vape: sample testing protocol guide
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.

Compliance without the last-minute scramble
We ship THC vape products to distributors, chain buyers and independent shops. What follows is the material we normally cover in a first conversation: what we hold in stock, how we test it, how it ships, and what happens when a carton arrives damaged.
Age verification is not only a website problem. Retail packaging, shelf placement and staff scripting all carry compliance weight, and auditors increasingly ask for evidence of all three.
Regulation for THC vape products differs by country and sometimes by state. We do not pretend to be your lawyer, but we do keep the document pack current and we will tell you when a configuration cannot legally enter a market you have named.
Building an assortment that actually turns
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.
A practical starting order for brand owners is 300 units across two or three SKUs, not 300 units of one. That spreads the risk, gives your staff something to compare, and still hits the first price break.
Where defects actually come from
Leak complaints almost always trace back to one of three things: an over-torqued centre post, a seal that sat in a hot container, or a fill volume pushed past the design limit. We cap fill volume slightly below maximum for exactly that reason.
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.
- Batch codes traceable from carton back to production date
- Mixed SKU cartons to spread first-order risk
- Standing reorder schedule with a fixed cut-off
- Document pack prepared per destination market
- Consolidated or split shipping, quoted both ways
- Seven-day defect reporting with replace-or-credit
Reading a quotation properly
Currency moves more than most buyers expect over a twelve month supply plan. We quote in USD and hold the price for 30 days from confirmation so your margin calculation is not guesswork.
We publish a realistic band of 3.57 to 10.28 per unit for standard configurations at 300 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.
Specification summary
| Volume | 1.0 ml |
| Hardware | Cotton core |
| Thread | 510 thread |
| Airflow | Adjustable |
| Window | Full glass |
| Packaging | Child-resistant box |
| Minimum order | 200 units per SKU, mixed cartons allowed |
| Lead time | 30 working days after artwork approval |
None of this is complicated. It is just written down, which is more than most buyers get before they wire a deposit.
Frequently asked
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.
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.
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.
