VapeWholesaleHubSpotting Defects in Cartridge Before Shipment — Updated for 2026
Most first time importers of cartridge ask the same five questions. This page answers them in the order they usually arrive, with the numbers we quote internally rather than round marketing claims.
Where Cartridge Sits in the Range
Think about where cartridge sits in your customer's week. If it is a weekly restock, breadth matters less than availability. If it is an occasional treat, flavour range and display story carry more weight.
Turning Cartridge Into Repeats
A cartridge display that answers strength and flavour without staff involvement outsells a prettier one that does not. Most customers will not ask, so the fixture has to do the work.

Where Demand Is Heading
One visible change in cartridge is the move towards clearer labelling and traceability. Retailers who adopted batch coding early are finding it much easier to work with larger distributors now.
How Cartridge Batches Are Checked
Keep a photo record of every cartridge approval sample. Written descriptions age badly; a dated photograph next to a delivered unit settles most arguments in seconds.
The cheapest quality control step is a retained sample. Keeping three sealed units from every cartridge batch costs almost nothing and turns any dispute into a simple comparison instead of an argument over photographs.
- Keep sealed retained samples from every production batch.
- Model landed cost, not ex-works price, when comparing quotes.
- Rotate stock by batch code rather than by delivery date.
- Write the complaint threshold into the order terms.
- Agree the tolerance band in writing before approving artwork.
The Specification That Matters
Where possible, tie part of the cartridge payment to inspection against the written spec. It focuses attention on the numbers rather than on the relationship.
Revisit the cartridge specification after every third order. Small improvements compound, and factories take a buyer more seriously when the document has clearly been used.
| Product category | Refillable kit |
|---|---|
| Resistance band | 0.6 - 0.8 ohm |
| Capacity tolerance | +/- 2% |
| Puff count method | Machine cycle 3s on / 27s off |
| Master carton | 300 units |
| Carton weight | 3.4 kg |
| Shelf life | 12 months |
| Storage | 15-25 C, dry, away from direct light |
Practical Checklist
- Agree the tolerance band in writing before approving artwork.
- Ask how the factory measures puff count, then compare like with like.
- Start with a mixed carton and let your own sell-through decide.
- Plan the switch from air to sea freight before you need it.
- Rotate stock by batch code rather than by delivery date.
- Confirm the current customs classification with your own broker.
Frequently Asked Questions
What if I only need a small first order?
That is normal and sensible. A mixed carton lets you test cartridge in your own market before committing to a production run, and the specification you approve at that stage carries through to larger orders unchanged.
Do you provide compliance documents?
Every shipment leaves with the documentation set relevant to your market, including batch records and test reports where required. Your local rules still determine what you must file, so confirm those with your broker before import.
What happens if my market changes its rules?
Regulations move, and packaging or documentation sometimes has to follow. We keep approved artwork files on hand so that a required change is a reprint rather than a redesign, which keeps the cost and delay down.
How are price changes handled on repeat orders?
{K} pricing is reviewed against input costs and volume rather than adjusted casually. Any change is confirmed in writing before the next order is scheduled, with the reason stated so you can judge it yourself.

Questions that are not answered here are usually the interesting ones. Reach out with the specifics of your market and we will answer with numbers rather than adjectives.
