How to source Vape Cartridge QC steps examples
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 first-time buyers.

Getting the documents right
This page is for first-time buyers who want a working answer on specification, price and lead time before they commit a purchase order. We have written the detail down so nobody has to sit through a sales call to extract it.
Advertising rules are stricter than product rules in most markets. Claims about cessation, health or comparative performance should stay off packaging and off your product pages unless your legal team has signed them off.
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.
Where the margin really sits
Unit price breaks usually land at 100, 300 and 600 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.
We publish a realistic band of 1.98 to 5.87 per unit for standard configurations at 100 units. Below that band you are buying a lighter specification; above it you are paying for finish, packaging or a smaller run.
Getting the carton there intact
Transit times move with the season. Book space early for Q4 and around Chinese New Year, when factory output pauses for two to three weeks and freight rates tighten at the same time.
Freight on vape cartridges is driven by volume more than weight. Cartons are designed to hit a clean pallet count, which is why a slightly denser pack can cut your landed cost by more than a discount on the unit price ever would.
- Seven-day defect reporting with replace-or-credit
- Specification locked in writing before production starts
- Mixed SKU cartons to spread first-order risk

- Standing reorder schedule with a fixed cut-off
- Document pack prepared per destination market
What happens when something goes wrong
For private label accounts we hold the artwork files and the approval record. Rebranding a line eighteen months later is then a file update instead of a redesign.
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.

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.
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.
How long does production take?
Around 15 working days after artwork approval for stock configurations, plus transit. Custom runs add roughly a week for tooling and a physical dummy. We confirm the date in writing on the order acknowledgement.
