VapeWholesaleHubMod Tamper Evidence and Seal Integrity — Landed Cost Worked Through
Mod has moved from a niche listing to a category that most vape retailers simply have to carry. That popularity brought a flood of near identical offers. This guide explains how to separate a repeatable supply chain from a lucky sample.
The Specification That Matters
A written mod specification should be short enough to read in a minute and precise enough to argue about. If a factory cannot confirm a number in writing, assume the number is whatever is cheapest that week.
Two specifications that matter more than buyers expect: the seal integrity after a drop test and the consistency of the draw from first use to last. Both are measurable before you commit to volume.

| Capacity tolerance | +/- 3% |
| Puff count method | Machine cycle 3s on / 27s off |
| Master carton | 300 units |
| Carton weight | 6.9 kg |
| Shelf life | 18 months |
| Storage | 15-25 C, dry, away from direct light |
Turning Mod Into Repeats
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.
Pricing and Margin
Margin on mod is rarely lost at the till. It is lost through dead stock, returns and emergency air freight. A slightly higher landed cost with predictable lead time usually beats the cheapest quote on the spreadsheet.
Indicative reference points for planning purposes: entry tier from USD 1.76 per unit at 500 units, mid tier at USD 1.33, and volume tier at USD 0.71 for full container quantities. These figures move with specification, packaging and freight, so treat them as a shape rather than a quote.
Positioning Mod on Your Shelf
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.
Freight, Customs and Timing
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.

Where Demand Is Heading
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.
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.
Practical Checklist
- Start with a mixed carton and let your own sell-through decide.
- Confirm the current customs classification with your own broker.
- Agree the tolerance band in writing before approving artwork.
- Model landed cost, not ex-works price, when comparing quotes.
- Rotate stock by batch code rather than by delivery date.
- Plan the switch from air to sea freight before you need it.
Frequently Asked Questions
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 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.
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.
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.
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.
Next Step
If you take one thing from this page, take the retained sample habit. It costs a few units per batch and it is the difference between a disagreement and a decision.
