VapeWholesaleHubHow to Brief a Factory on Cartridge — First-Time Importers
This page is written for the person who has to sign the purchase order, not for the person who designed the packaging. If you are weighing up cartridge right now, the sections below follow the order in which the real decisions tend to arrive.
What to Fix Before Approving Cartridge
When we write a cartridge specification with a distributor, we fix four things first: the resistance band, the liquid capacity tolerance, the puff count methodology and the packaging master carton. Everything else can flex without changing the customer experience.
A written cartridge specification should be short enough to read in a minute and precise enough to argue about. If a factory cannot confirm a number in writing, assume the number is whatever is cheapest that week.
| Product category | Open system |
|---|---|
| Resistance band | 0.6 - 0.8 ohm |
| Capacity tolerance | +/- 3% |
| Puff count method | Machine cycle 2s on / 18s off |
| Master carton | 240 units |
| Carton weight | 10.9 kg |
| Shelf life | 24 months |
| Storage | 15-25 C, dry, away from direct light |
Turning Cartridge Into Repeats
Online, the listing for cartridge should answer three questions without scrolling: what it is, how strong it is, and what it tastes like. Everything else belongs further down the page.
Getting Cartridge to Your Warehouse
Air freight makes sense for a first cartridge order when you need to test demand quickly, but almost every steady programme moves to sea freight once volumes stabilise. Planning that switch early avoids a painful margin squeeze later.
Where Demand Is Heading
Retailers report that cartridge customers are asking more specific questions than they did two years ago. That favours ranges with clear, simple information over ranges with clever marketing.
Modelling a Healthy Margin
Compare cartridge quotes on the same incoterm. A price that looks better because it excludes a cost you assumed was included is not a saving at all.
Indicative reference points for planning purposes: entry tier from USD 1.75 per unit at 500 units, mid tier at USD 0.98, and volume tier at USD 1.33 for full container quantities. These figures move with specification, packaging and freight, so treat them as a shape rather than a quote.
Inspection Before Dispatch
Incoming inspection for cartridge is not about opening boxes at random. We weigh a sample of cartons, check batch codes against the production record, run a draw resistance measurement, and log the results so that a complaint three months later can be traced to a specific run.
Set the cartridge complaint threshold in the contract before you need it. Deciding what counts as an acceptable defect rate during a dispute is the worst possible time to negotiate it.
- Model landed cost, not ex-works price, when comparing quotes.
- Rotate stock by batch code rather than by delivery date.
- Keep sealed retained samples from every production batch.
- Check carton dimensions against your freight quote before confirming.
- Start with a mixed carton and let your own sell-through decide.
Practical Checklist
- Write the complaint threshold into the order terms.
- Confirm the current customs classification with your own broker.
- Check carton dimensions against your freight quote before confirming.
- Agree the tolerance band in writing before approving artwork.
- Keep sealed retained samples from every production batch.
- Model landed cost, not ex-works price, when comparing quotes.
Frequently Asked Questions
Can I visit the production facility?
Yes, and we encourage it for larger programmes. Visits are most useful when you already have a draft specification, because you can then check the specific processes behind the numbers you care about.
Can I mix strengths in one order?
In most cases yes, as long as each strength meets the minimum run length. Mixed strength cartons are popular with retailers building their first display because they show the full ladder without over committing.
What if a batch does not match the sample?
Keep the retained samples from the approval stage. If a delivered batch measurably differs, we compare against the retained set and resolve it against the production record. This is why we insist on sealed retained units from every run.
Can the packaging be customised?
Yes. Most cartridge programmes use private label packaging once volumes justify the printing plate. We supply dielines, check your artwork for print issues and hold approved files so reorders need no new setup.
Do you hold stock for regular customers?
For established programmes we can reserve production slots and, in some cases, hold finished cartridge stock against a forecast. It removes most of the lead time risk from a reorder and is worth discussing once volumes are stable.
Next Step
The best cartridge programmes we see are run by buyers who write things down. Specifications, batch records, complaint thresholds - the paperwork is the advantage.
