Sourcing Vape Juice: sample testing protocol guide
Vape Juice sits in a crowded price band, and the cheapest quote on the sheet is rarely the cheapest unit on your shelf. Everything below is built around reorder rate, defect rate and cash conversion rather than headline unit price.

Transit, consolidation and timing
We ship vape juices 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.
For repeat buyers we hold a shipping schedule rather than shipping on request. A fixed weekly cut-off means your reorder lands before the shelf empties instead of after.
Documentation travels with the goods: commercial invoice, packing list, and the certificate set for your market. We send a scanned copy before dispatch so your broker can clear the file in advance.
Reading a quotation properly
Freight is quoted separately and honestly. Bundling it into the unit price looks tidy and hides the one line that changes most often between shipments.
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.
Sell-through notes for the shop floor
Seasonality in vape juices is real but smaller than most buyers assume. The bigger swing comes from restocking discipline, not from calendar events.
Shelf position decides velocity as much as price. Keep vape juices at eye level, one facing per SKU, and rotate the trial line every quarter so the display keeps earning attention.
- Batch codes traceable from carton back to production date
- Artwork proof plus physical dummy for custom packaging
- Specification locked in writing before production starts
- Seven-day defect reporting with replace-or-credit
- Reference sample retained from every batch
- Mixed SKU cartons to spread first-order risk
Labels, closures and traceability
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.
If you sell into a market that requires child-resistant packaging, say so at quotation stage. Retrofitting a CR closure onto a finished bottle design usually means a new mould and a four week delay.

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 is the minimum order for vape juice?
Standard configurations start at 100 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 300 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.
