Vape Juice sample testing protocol playbook
A vape juice 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.

Getting the documents right
Buyers come to us for vape juice after a bad quarter: dead stock on one side, empty shelves on the other. The cause is usually the same, an assortment built from a catalogue instead of from sell-through data. This page explains how we rebuild that balance for convenience store chains.
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.
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.
Simple habits that lift velocity
Counter space is finite. Three well-chosen SKUs outsell nine crowded ones, and the empty space signals a curated range rather than a clearance table.
Seasonality in vape juices is real but smaller than most buyers assume. The bigger swing comes from restocking discipline, not from calendar events.
What a sensible opening order looks like
Colour range is where assortments quietly die. Six finishes look impressive in a brochure and disastrous on a shelf with 40 cm of space. We recommend two finishes per core SKU and let the trial line carry the novelty.
When you compare suppliers for vape juice, 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.
- Specification locked in writing before production starts
- Named account contact who has handled the product
- Cartons drop-tested and pallet-counted for clean freight
- Mixed SKU cartons to spread first-order risk
- Reference sample retained from every batch
- Seven-day defect reporting with replace-or-credit
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.
12 separate checks run before a carton is sealed: electrical, mechanical, leak, finish and packaging. Anything outside tolerance is quarantined the same day and reported to you, rather than shipped with a hope and a discount.

Frequently asked
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 is the minimum order for vape juice?
Standard configurations start at 300 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 800 units because of setup time on the line.
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.
