VapeWholesaleHubMod Quality Control: Tests We Run Before Dispatch — Busy Buyers
Everything below applies whether you are ordering one mixed carton or a full container. The numbers scale, but the logic does not change, which is the point of writing it down once.
Trends Worth Watching
Flavour cycles in mod are shortening, which argues for smaller test orders and faster feedback loops rather than large speculative buys on a predicted winner.
The most durable mod lines over the last few years have been unglamorous and consistent. Novelty sells once; reliability sells every month.
Inspection Before Dispatch
Keep a photo record of every mod approval sample. Written descriptions age badly; a dated photograph next to a delivered unit settles most arguments in seconds.
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.
- Plan the switch from air to sea freight before you need it.
- Agree the tolerance band in writing before approving artwork.
- 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.
Reading a Mod Spec Sheet
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.
When we write a mod specification with a distributor, we fix four things first: the resistance band, the liquid capacity tolerance, the puff count methodology and the packaging master carton. Everything else can flex without changing the customer experience.
| Product category | Refillable kit |
|---|---|
| Resistance band | 1.0 - 1.2 ohm |
| Capacity tolerance | +/- 3% |
| Puff count method | Machine cycle 3s on / 27s off |
| Master carton | 200 units |
| Carton weight | 8.8 kg |
| Shelf life | 18 months |
| Storage | 15-25 C, dry, away from direct light |
Positioning Mod on Your Shelf
Think about where mod sits in your customer's week. If it is a weekly restock, breadth matters less than availability. If it is an occasional treat, flavour range and display story carry more weight.
Selling Mod at Store Level
A mod display that answers strength and flavour without staff involvement outsells a prettier one that does not. Most customers will not ask, so the fixture has to do the work.
Online, the listing for mod should answer three questions without scrolling: what it is, how strong it is, and what it tastes like. Everything else belongs further down the page.
Freight, Customs and Timing
Customs classification for mod varies by market and changes from time to time. We ship with full documentation, but your broker should confirm the current code before your first order rather than after it lands.
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.
Practical Checklist
- Plan the switch from air to sea freight before you need it.
- Check carton dimensions against your freight quote before confirming.
- Ask how the factory measures puff count, then compare like with like.
- Model landed cost, not ex-works price, when comparing quotes.
- Confirm the current customs classification with your own broker.
- Write the complaint threshold into the order terms.
Frequently Asked Questions
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.
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.
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 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.
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
Whether you order from us or elsewhere, keep a retained sample from every batch. It costs almost nothing and it is the single most effective protection available to a mod buyer.
