VapeWholesaleHubMod Specification Change Control — Updated for 2026
We ship mod to distributors in very different markets, and the same five questions come up almost every week. Rather than answer them in email each time, we have written them out properly here.
Where Demand Is Heading
Retailers report that mod customers are asking more specific questions than they did two years ago. That favours ranges with clear, simple information over ranges with clever marketing.
Quality Control in Practice
Set the mod 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.

- Agree the tolerance band in writing before approving artwork.
- Keep sealed retained samples from every production batch.
- Rotate stock by batch code rather than by delivery date.
- Ask how the factory measures puff count, then compare like with like.
- Confirm the current customs classification with your own broker.
Pricing and Margin
When you model mod pricing, build in a realistic shrink figure. Even a well run line loses a small percentage to damage, expiry and sampling. Pretending that number is zero is how a healthy looking margin turns negative.
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 1.72 per unit at 1000 units, mid tier at USD 1.23, and volume tier at USD 0.79 for full container quantities. These figures move with specification, packaging and freight, so treat them as a shape rather than a quote.
The Specification That Matters
Ask any factory for the same mod sample twice, three months apart. If the second sample drifts, the production line is running without statistical control and your reviews will drift with it. Consistency over time is a more useful signal than a single good sample.

Freight, Customs and Timing
Track mod 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.
Air freight makes sense for a first mod 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.
Practical Checklist
- Rotate stock by batch code rather than by delivery date.
- Confirm the current customs classification with your own broker.
- Model landed cost, not ex-works price, when comparing quotes.
- Plan the switch from air to sea freight before you need it.
- Agree the tolerance band in writing before approving artwork.
- Start with a mixed carton and let your own sell-through decide.
Frequently Asked Questions
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.
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.
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.
Do you hold stock for regular customers?
For established programmes we can reserve production slots and, in some cases, hold finished mod stock against a forecast. It removes most of the lead time risk from a reorder and is worth discussing once volumes are stable.
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.
Next Step
Send us your current mod specification even if you are not planning to move suppliers. A second read of a document you use every month is usually worth the ten minutes.
