Vape Cartridge connection with COA guide
We work with adult smokers 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.

What happens when something goes wrong
Ordering vape cartridge is not difficult. Ordering vape cartridge that sell through without a return queue behind them is the part most buyers underestimate, and it is where we spend our time. We supply adult smokers in European and North American markets with core lines that turn over predictably, and we keep the specification list short enough for your team to actually manage.
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.
Returns are handled as data, not as complaints. Every reported failure is logged by mode and by batch, and the pattern is reviewed monthly with the factory.
Building an assortment that actually turns
Sourcing trips still matter for volume buyers. Seeing the line, the ageing room and the packing station tells you in an hour what six emails cannot. We host visits by appointment and we do not stage them.
We keep a short list of approved configurations for vape cartridges. Anything outside that list is possible, but it becomes a custom run with a custom lead time, and we quote it as such rather than pretending everything is standard.
Labels, closures and traceability
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.
Labels are where good orders go wrong. Nicotine warnings, child-resistant closures, batch coding and market-specific text all have to be correct before the pallet leaves. We prepare test reports, declaration of conformity and safety data sheets for each shipment and we ask for your destination list early so artwork matches the market.
- Batch codes traceable from carton back to production date
- Named account contact who has handled the product
- Document pack prepared per destination market
- Seven-day defect reporting with replace-or-credit
- Standing reorder schedule with a fixed cut-off
- Consolidated or split shipping, quoted both ways
Reading a quotation properly
Payment terms for new accounts are normally a deposit with the balance against the bill of lading. Established buyers on a repeat schedule can move to terms after three clean shipments.
We publish a realistic band of 1.95 to 5.78 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.
Specification summary
| Volume | 1.0 ml |
| Core | Mesh |
| Resistance | 1.8 ohm |
| Thread | Press-fit |
| Airflow | Bottom |
| Packaging | Tube |
| Minimum order | 50 units per SKU, mixed cartons allowed |
| Lead time | 30 working days after artwork approval |
We would rather lose an order at quotation stage than explain a mismatch after delivery, which is why the specification conversation comes before the price conversation.
Frequently asked
How long does production take?
Around 28 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.
How do you handle repeat orders?
The specification is held on file against your account, so a reorder is a reference rather than a new brief. We recommend a standing schedule with a fixed weekly cut-off so stock lands before the shelf empties.
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.
