Buyers often ask us to explain why two cartridge samples that look identical behave differently after a month. The answer is almost always tolerance control, and it is more interesting than it sounds.
Where Demand Is Heading
Traceability is moving from a nice-to-have to a requirement in several cartridge markets. Building the habit now is cheaper than retrofitting record keeping under pressure later.
Freight, Customs and Timing
Track cartridge landed cost per unit as a running number, including duty and local delivery. It is the only figure that tells you whether a supplier change actually improved anything.

The Specification That Matters
Specification sheets are where a cartridge deal is won or quietly lost. Two samples can look and taste the same while using different coil wire, different wicking density and different tolerances on the mouthpiece. Those details decide how the unit behaves in week three rather than minute three.
| Product category | Open system |
|---|---|
| Resistance band | 1.2 - 1.4 ohm |
| Capacity tolerance | +/- 2% |
| Puff count method | Declared by capacity |
| Master carton | 400 units |
| Carton weight | 5.4 kg |
| Shelf life | 24 months |
| Storage | 15-25 C, dry, away from direct light |
How Cartridge Fits the Assortment
Category data for cartridge is noisier than it looks. Promotions, weather and local competition all move weekly numbers, so read three months at a time rather than reacting to a single week.
Cartridge sits at an interesting point in the assortment. It is familiar enough to be an impulse purchase and specific enough to build a repeat pattern around. Treating it as either pure commodity or pure specialty both lead to poor results.
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.
- Agree the tolerance band in writing before approving artwork.
- Ask how the factory measures puff count, then compare like with like.
- Keep sealed retained samples from every production batch.
- Start with a mixed carton and let your own sell-through decide.
- Write the complaint threshold into the order terms.
Practical Checklist
- Agree the tolerance band in writing before approving artwork.
- Rotate stock by batch code rather than by delivery date.
- Ask how the factory measures puff count, then compare like with like.
- Plan the switch from air to sea freight before you need it.
- Write the complaint threshold into the order terms.
- Model landed cost, not ex-works price, when comparing quotes.
Frequently Asked Questions
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.
What does a sample pack usually include?
A typical cartridge sample pack covers the strengths or variants you are most likely to list, packed so you can evaluate them side by side. Tell us which lines you are considering and we will match the pack to that rather than sending a generic selection.
How should cartridge be stored?
Cool, dry and out of direct sunlight. Heat and light are the two things that shorten shelf life fastest. Rotate stock by batch code rather than by arrival date, and keep cartons off concrete floors in humid warehouses.
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.
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.
