Mod Specification Change Control — a Factory Floor View
Mod has moved from a niche listing to a category that most vape retailers simply have to carry. That popularity brought a flood of near identical offers. This guide explains how to separate a repeatable supply chain from a lucky sample.
Pricing and Margin
Build mod price tiers around order sizes your customers actually place. Tiers that only make sense on a spreadsheet get ignored, and you end up discounting ad hoc instead.
Tiered pricing works best when the tiers match real customer behaviour. Most mod buyers will take the second tier if the step is modest and the third tier only if they can see a genuine reason to hold more stock.
Indicative reference points for planning purposes: entry tier from USD 0.92 per unit at 2000 units, mid tier at USD 0.99, and volume tier at USD 0.51 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
Most defects in mod are not dramatic. They are loose tolerances, a slightly thin seal, a mouthpiece that clicks. Left alone they turn into leak complaints, which are the single most common reason a retailer drops a line.
- Start with a mixed carton and let your own sell-through decide.
- Keep sealed retained samples from every production batch.
- Ask how the factory measures puff count, then compare like with like.
- Rotate stock by batch code rather than by delivery date.
- Agree the tolerance band in writing before approving artwork.
Reading a Mod Spec Sheet
A written mod 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.
Revisit the mod specification after every third order. Small improvements compound, and factories take a buyer more seriously when the document has clearly been used.
| Product category | Closed pod |
|---|---|
| Resistance band | 1.0 - 1.2 ohm |
| Capacity tolerance | +/- 2% |
| Puff count method | Machine cycle 3s on / 27s off |
| Master carton | 240 units |
| Carton weight | 9.1 kg |
| Shelf life | 24 months |
| Storage | 15-25 C, dry, away from direct light |
Where Mod Sits in the Range
Mod rewards retailers who can explain it in one sentence. If your team needs a paragraph, the range is too complicated for the space it occupies.
Freight, Customs and Timing
Consolidating mod with other lines is often the biggest single saving available to a mid size importer. The unit cost does not change but the landed cost does, sometimes materially.

Trends Worth Watching
One shift worth planning for: shorter mod reorder cycles with smaller average drops. It favours suppliers with flexible production slots over those who only want large annual commitments.
Practical Checklist
- Keep sealed retained samples from every production batch.
- Write the complaint threshold into the order terms.
- Ask how the factory measures puff count, then compare like with like.
- Confirm the current customs classification with your own broker.
- Check carton dimensions against your freight quote before confirming.
- Model landed cost, not ex-works price, when comparing quotes.
Frequently Asked Questions
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.
Is there a warranty on mod?
Manufacturing defects are covered against the retained sample standard. Normal wear, misuse and damage after opening are not. We publish the threshold in the order terms so both sides know exactly what the claim process looks like.
How should mod 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.
Can you match an existing product I already sell?
Often yes, provided we can measure it properly. Send a physical sample and we will report back on what can be matched, what will differ slightly, and why. An honest gap is more useful than a vague promise.
What if I only need a small first order?
That is normal and sensible. A mixed carton lets you test mod in your own market before committing to a production run, and the specification you approve at that stage carries through to larger orders unchanged.
Next Step
If you take one thing from this page, take the retained sample habit. It costs a few units per batch and it is the difference between a disagreement and a decision.
