Vape Cartridge sample testing protocol — a primer
We work with first-time 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.

Transit, consolidation and timing
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.
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.
We ship from Shenzhen and Guangzhou: air express for samples and part loads, sea freight for volume. Typical production lead time is 12 working days after artwork approval, plus transit. We quote both routes so you can see the trade-off instead of guessing at it.
Presentation that earns the step-up
Counter space is finite. Three well-chosen SKUs outsell nine crowded ones, and the empty space signals a curated range rather than a clearance table.
Seasonality in vape cartridges is real but smaller than most buyers assume. The bigger swing comes from restocking discipline, not from calendar events.
Paperwork, labelling and market rules
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.
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.
- Mixed SKU cartons to spread first-order risk
- Batch codes traceable from carton back to production date
- Consolidated or split shipping, quoted both ways
- Specification locked in writing before production starts
- Private label files archived for future rebrands
- Named account contact who has handled the product
What happens when something goes wrong
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.
Technical questions usually arrive at the worst possible moment, which is why we answer them on WhatsApp as well as email. A photo and a two line message resolves most issues faster than a ticket.

If any of this is unclear, the fastest route is a message rather than a meeting. Send the market you sell into and the price band you work in, and you will get a specific answer instead of a brochure.
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.
What is the minimum order for vape cartridge?
Standard configurations start at 120 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.
How long does production take?
Around 12 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.
