VapeWholesaleHubMod Quality Control: Tests We Run Before Dispatch — Before Your Next Order
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.
The Specification That Matters
Specification sheets are where a mod 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 | Accessory |
|---|---|
| Resistance band | 0.8 - 1.0 ohm |
| Capacity tolerance | +/- 3% |
| Puff count method | Machine cycle 3s on / 27s off |
| Master carton | 200 units |
| Carton weight | 6.0 kg |
| Shelf life | 18 months |
| Storage | 15-25 C, dry, away from direct light |
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.
How Mod Fits the Assortment
Range decisions for mod should start from shelf space, not from a supplier catalogue. Count the facings you actually have, then decide how many of them this line deserves against what it currently earns.
A tight mod range with deep availability usually outsells a wide range with thin stock. Customers who find their line in stock come back; customers who are told to wait do not.
Quality Control in Practice
Random checks are fine, but weight the sample towards the start and end of a mod production run. Those are where a line is most likely to drift.
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.
- Check carton dimensions against your freight quote before confirming.
- Ask how the factory measures puff count, then compare like with like.
- Keep sealed retained samples from every production batch.
- Write the complaint threshold into the order terms.
- Agree the tolerance band in writing before approving artwork.
Trends Worth Watching
Traceability is moving from a nice-to-have to a requirement in several mod markets. Building the habit now is cheaper than retrofitting record keeping under pressure later.
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.
Selling Mod at Store Level
On shelf, mod sells on clarity. A plain shelf talker that states strength and flavour in two words outperforms a beautifully designed but vague display, because most purchase decisions here take under ten seconds.
Practical Checklist
- Plan the switch from air to sea freight before you need it.
- Model landed cost, not ex-works price, when comparing quotes.
- 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.
- Write the complaint threshold into the order terms.
Frequently Asked Questions
Can the packaging be customised?
Yes. Most mod programmes use private label packaging once volumes justify the printing plate. We supply dielines, check your artwork for print issues and hold approved files so reorders need no new setup.
What is the usual minimum order for mod?
For a standard production run the minimum is normally one master carton per flavour, though mixed cartons can be arranged for a first order. If you are testing the line, ask about a sample pack first and treat the freight as part of your research budget.
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.
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.
What if a batch does not match the sample?
Keep the retained samples from the approval stage. If a delivered batch measurably differs, we compare against the retained set and resolve it against the production record. This is why we insist on sealed retained units from every run.
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.
