VapeWholesaleHubMod Emissions and Leak Testing Methods — Private Label Programmes
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.
Market Signals
One visible change in mod 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.
Where Mod Sits in the Range
Category data for mod 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.
Logistics That Protect Margin
Carton dimensions for mod are a design decision, not a packing afterthought. A few centimetres on the master carton can change how many units fit a pallet, and that repeats on every order.
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.
The Specification That Matters
Where possible, tie part of the mod payment to inspection against the written spec. It focuses attention on the numbers rather than on the relationship.
| Product category | Open system |
|---|---|
| Resistance band | 1.0 - 1.2 ohm |
| Capacity tolerance | +/- 5% |
| Puff count method | Declared by capacity |
| Master carton | 100 units |
| Carton weight | 3.5 kg |
| Shelf life | 18 months |
| Storage | 15-25 C, dry, away from direct light |
How Mod Batches Are Checked
Train whoever receives mod cartons to note anything unusual at the point of unloading. Damage discovered at the dock is a freight claim; damage discovered a week later is your problem.
- Keep sealed retained samples from every production batch.
- Write the complaint threshold into the order terms.
- Check carton dimensions against your freight quote before confirming.
- Ask how the factory measures puff count, then compare like with like.
- Start with a mixed carton and let your own sell-through decide.
Practical Checklist
- Plan the switch from air to sea freight before you need it.
- Confirm the current customs classification with your own broker.
- Rotate stock by batch code rather than by delivery date.
- 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.
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.
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.
Is there support for in-store material?
Yes. Shelf talkers, counter cards and simple planogram suggestions are available for mod ranges that reach a sensible volume. Most retailers find the plain strength and flavour cards do the most work.
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.
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.
