Vape Juice quality control steps — a walkthrough
If you are comparing three quotes for vape juice, 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.

Where defects actually come from
We work with B2B buyers 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.
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.
Flavour drift between batches is the quiet killer of repeat orders. We retain a sealed reference sample from every run so a complaint six weeks later can be compared against what actually left the building.
Reading a quotation properly
Unit price breaks usually land at 200, 500 and 1000 pieces. Between those steps the cost curve flattens, which is why pushing a 200 unit order to 500 often costs less per unit than buyers expect.
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.
Choosing the core line
We source vape juices from a small group of factories we have worked with for years. That means a specification can be held across repeat orders instead of being re-qualified from scratch every quarter. Consistency is a boring selling point and it is also the entire game.
The first question we ask is not what you want to spend. It is what your customer already buys. Answer that and the vape juice list writes itself; skip it and you end up with a pallet of stock that photographs well and sells badly.
- Named account contact who has handled the product
- Batch codes traceable from carton back to production date
- Seven-day defect reporting with replace-or-credit
- Document pack prepared per destination market
- Reference sample retained from every batch
- Mixed SKU cartons to spread first-order risk
Shipping without surprises
We can consolidate mixed orders of vape juices into one shipment. Consolidation saves freight but adds handling days, so we quote both a consolidated and a split option and let you choose.
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.

Frequently asked
What is the minimum order for vape juice?
Standard configurations start at 200 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 500 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.
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.
