Vape Cartridge quality agreement — basics
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.

Quality control, in plain terms
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 convenience store chains.
A 0.5 percent defect rate sounds excellent until it lands on a 600 unit order and you are handling three returns in a week. We quote realistic rates per category and we credit in advance for the known failure modes.
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.
After-sales, replacements and reorders
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.
Every account gets a named contact who has actually seen the product. Being passed between three people to answer one question about a coil resistance is the fastest way to lose a buyer, so we do not organise support that way.
Simple habits that lift velocity
Seasonality in vape cartridges 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 cartridges at eye level, one facing per SKU, and rotate the trial line every quarter so the display keeps earning attention.
- Private label files archived for future rebrands
- Document pack prepared per destination market
- Reference sample retained from every batch
- Cartons drop-tested and pallet-counted for clean freight
- Specification locked in writing before production starts
- Artwork proof plus physical dummy for custom packaging
Reading a quotation properly
The cheapest way to lower your cost per unit is usually to remove a SKU, not to negotiate a discount. Fewer lines means larger runs, fewer changeovers and a better price at the same quality.
Custom printing raises the unit price and lowers the marketing cost. For convenience store chains the break-even is usually reached on the second or third repeat order, not the first, so we quote both branded and neutral options.

Frequently asked
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 we order samples before committing?
Yes. Sample orders are shipped by air express and the cost is credited against your first production order above 60 units. We would rather you handle the sample than approve a specification from a photograph.
What is the minimum order for vape cartridge?
Standard configurations start at 60 units per SKU, with mixed SKUs allowed inside the same carton. Custom colours, custom packaging or a private label run usually start at 240 units because of setup time on the line.
