Sourcing Vape Juice: sample testing protocol tips
We work with convenience store chains 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.

Paperwork, labelling and market rules
Vape Juice is a specification decision before it is a price decision. Get the resistance, the capacity and the packaging right and the price conversation becomes short. Get them wrong and no discount will rescue the order.
Regulation for vape juices 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.
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.
Support that answers the question
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.
The replacement policy is deliberately simple: report within seven days of delivery with photos and the batch code, and we replace or credit at the next shipment. We do not argue about a defect we can see in a photograph.
Unit price versus landed cost
A landed cost sheet for vape juice has five lines: unit price, packaging, freight, duty and the cost of defects. Quoting only the first line is how buyers end up surprised at the fourth.
We publish a realistic band of 1.03 to 3.99 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.
- Batch codes traceable from carton back to production date
- Seven-day defect reporting with replace-or-credit
- Mixed SKU cartons to spread first-order risk
- Cartons drop-tested and pallet-counted for clean freight
- Standing reorder schedule with a fixed cut-off
- Reference sample retained from every batch
Batch consistency and why it matters
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.
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.
Specification summary
| Volume | 100 ml |
| Strength | 3 mg |

| Closure | Child resistant |
| Bottle | PET |
| Minimum order | 100 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 we order samples before committing?
Yes. Sample orders are shipped by air express and the cost is credited against your first production order above 300 units. We would rather you handle the sample than approve a specification from a photograph.
How long does production take?
Around 28 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.
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.
