VapeWholesaleHubMod Tamper Evidence and Seal Integrity — 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.
Inspection Before Dispatch
Most defects in mod are not dramatic. They are loose tolerances, a slightly thin seal, a mouthpiece that clicks. Left alone they turn into leak complaints, which are the single most common reason a retailer drops a line.
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.
- Ask how the factory measures puff count, then compare like with like.
- Write the complaint threshold into the order terms.
- Rotate stock by batch code rather than by delivery date.
- Confirm the current customs classification with your own broker.
- Plan the switch from air to sea freight before you need it.
Positioning Mod on Your Shelf
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.
Logistics That Protect Margin
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.
Model mod freight both ways before choosing a method: cost per unit and cost per week of delay. The second figure is the one that decides whether a cheap option was actually cheap.
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.
| Product category | Open system |
|---|---|
| Resistance band | 1.2 - 1.4 ohm |
| Capacity tolerance | +/- 3% |
| Puff count method | Machine cycle 2s on / 18s off |
| Master carton | 400 units |
| Carton weight | 8.8 kg |
| Shelf life | 12 months |
| Storage | 15-25 C, dry, away from direct light |
Pricing and Margin
Build mod price tiers around order sizes your customers actually place. Tiers that only make sense on a spreadsheet get ignored, and you end up discounting ad hoc instead.
Indicative reference points for planning purposes: entry tier from USD 2.36 per unit at 2000 units, mid tier at USD 1.04, and volume tier at USD 1.40 for full container quantities. These figures move with specification, packaging and freight, so treat them as a shape rather than a quote.
Practical Checklist
- Check carton dimensions against your freight quote before confirming.
- Start with a mixed carton and let your own sell-through decide.
- Write the complaint threshold into the order terms.
- Agree the tolerance band in writing before approving artwork.
- Ask how the factory measures puff count, then compare like with like.
- Plan the switch from air to sea freight before you need it.
Frequently Asked Questions
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 information do you need to quote?
Target specification, approximate quantity, destination and any packaging requirement. With those four we can usually come back with a costed option the same working day rather than a request for more information.
How are price changes handled on repeat orders?
{K} pricing is reviewed against input costs and volume rather than adjusted casually. Any change is confirmed in writing before the next order is scheduled, with the reason stated so you can judge it yourself.
How long does a mod order take to arrive?
Production typically takes ten to eighteen working days after artwork approval, and transit depends on the method you choose. Air express is fastest, sea freight is cheapest at volume. We confirm both at quotation so there is no surprise later.
Next Step
Start smaller than feels comfortable, measure honestly, then scale what worked. That sequence has saved more of our customers money than any negotiation tactic we could suggest.
