How to source Vape Cartridge sample testing protocol
Buyers come to us for vape cartridge 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 B2B buyers.

Quality control, in plain terms
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.
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.
Every batch is pulled from running production, not from a display shelf. We check draw resistance, airflow balance, charge behaviour, leak performance after a temperature shift, finish quality and carton integrity, and we keep the pull records against the order number.
Support that answers the question
Reorders are the real test of a supplier. If the second shipment does not match the first, the relationship is over regardless of price, so we treat the reorder as the actual deliverable.
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.
What a sensible opening order looks like
The first question we ask is not what you want to spend. It is what your customer already buys. Answer that and the vape cartridge list writes itself; skip it and you end up with a pallet of stock that photographs well and sells badly.
A practical starting order for B2B buyers is 240 units across two or three SKUs, not 240 units of one. That spreads the risk, gives your staff something to compare, and still hits the first price break.
- Batch codes traceable from carton back to production date
- Document pack prepared per destination market
- Seven-day defect reporting with replace-or-credit
- Specification locked in writing before production starts
- Cartons drop-tested and pallet-counted for clean freight
- Consolidated or split shipping, quoted both ways
Where the margin really sits
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.
We publish a realistic band of 1.84 to 5.37 per unit for standard configurations at 240 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.

Frequently asked
What is the minimum order for vape cartridge?
Standard configurations start at 240 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 600 units because of setup time on the line.
Do you support private label?
We do. Send your artwork or your brand direction and we will return a digital proof, then a physical dummy for colour approval. Packaging files stay on record so a rebrand later is a file update rather than a redesign.
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 240 units. We would rather you handle the sample than approve a specification from a photograph.
