VapeWholesaleHubMod Quality Control: Tests We Run Before Dispatch — First-Time Importers
Most first time importers of mod 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.
Getting Mod to Your Warehouse
Freight is the hidden half of mod unit economics. A denser master carton can save more per unit than a hard negotiation on factory price, because the saving repeats on every reorder rather than once.
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.
How Mod Batches Are Checked
The cheapest quality control step is a retained sample. Keeping three sealed units from every mod batch costs almost nothing and turns any dispute into a simple comparison instead of an argument over photographs.
AQL sampling gets a lot of attention, but for mod the more useful habit is simply measuring the same three things on every single batch. Trend lines catch problems that pass/fail checks miss.
- Check carton dimensions against your freight quote before confirming.
- Ask how the factory measures puff count, then compare like with like.
- Agree the tolerance band in writing before approving artwork.
- Rotate stock by batch code rather than by delivery date.
- Model landed cost, not ex-works price, when comparing quotes.
Reading a Mod Spec Sheet
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.
Ask for the mod specification in the same units you intend to measure in. A metric quoted in a form you cannot verify on arrival is not a specification, it is a claim.
| Product category | Open system |
|---|---|
| Resistance band | 0.8 - 1.0 ohm |
| Capacity tolerance | +/- 5% |
| Puff count method | Machine cycle 3s on / 27s off |
| Master carton | 240 units |
| Carton weight | 5.3 kg |
| Shelf life | 18 months |
| Storage | 15-25 C, dry, away from direct light |
Merchandising and Listing Tips
Rotate mod facing rather than price for the first month. Visibility changes sell-through more reliably than a small discount, and it does not train customers to wait for offers.
How Mod Fits the Assortment
Before anything else, decide which customer you are buying mod for. A convenience counter with limited shelf depth needs a tight range that turns quickly, while a specialist shop can carry a deeper ladder of options and educate buyers into higher ticket lines.
Practical Checklist
- Ask how the factory measures puff count, then compare like with like.
- Confirm the current customs classification with your own broker.
- Start with a mixed carton and let your own sell-through decide.
- Plan the switch from air to sea freight before you need it.
- Model landed cost, not ex-works price, when comparing quotes.
- Keep sealed retained samples from every production batch.
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.
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.
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.
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.
Next Step
Nobody wins when a first order is too large to learn from. Start with a mixed carton, check how it moves in your own market, then scale the lines that earned the shelf space.
