VapeWholesaleHubHow to Read a Mods Certificate of Analysis — a Printable Checklist
Mods 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.
Inspection Before Dispatch
AQL sampling gets a lot of attention, but for mods the more useful habit is simply measuring the same three things on every single batch. Trend lines catch problems that pass/fail checks miss.
- Start with a mixed carton and let your own sell-through decide.
- Rotate stock by batch code rather than by delivery date.
- Ask how the factory measures puff count, then compare like with like.
- Plan the switch from air to sea freight before you need it.
- Agree the tolerance band in writing before approving artwork.
The Specification That Matters
Ask for the mods 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.
A written mods 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.
| Product category | Accessory |
|---|---|
| Resistance band | 0.6 - 0.8 ohm |
| Capacity tolerance | +/- 5% |
| Puff count method | Machine cycle 3s on / 27s off |
| Master carton | 300 units |
| Carton weight | 7.8 kg |
| Shelf life | 24 months |
| Storage | 15-25 C, dry, away from direct light |
How Mods Fits the Assortment
Mods rewards retailers who can explain it in one sentence. If your team needs a paragraph, the range is too complicated for the space it occupies.
Pricing and Margin
Discounting mods to win shelf space tends to reset customer expectations permanently. Volume support in kind, such as display material, usually costs less in the long run.

Indicative reference points for planning purposes: entry tier from USD 0.88 per unit at 500 units, mid tier at USD 0.78, and volume tier at USD 0.60 for full container quantities. These figures move with specification, packaging and freight, so treat them as a shape rather than a quote.
Freight, Customs and Timing
Track mods 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.
Practical Checklist
- Keep sealed retained samples from every production batch.
- Agree the tolerance band in writing before approving artwork.
- Plan the switch from air to sea freight before you need it.
- Check carton dimensions against your freight quote before confirming.
- Model landed cost, not ex-works price, when comparing quotes.
- Start with a mixed carton and let your own sell-through decide.
Frequently Asked Questions
How should mods 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.
Do you provide compliance documents?
Every shipment leaves with the documentation set relevant to your market, including batch records and test reports where required. Your local rules still determine what you must file, so confirm those with your broker before import.
What is the usual minimum order for mods?
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.
Can I mix strengths in one order?
In most cases yes, as long as each strength meets the minimum run length. Mixed strength cartons are popular with retailers building their first display because they show the full ladder without over committing.
Next Step
Whatever you decide, decide it against numbers you can check on arrival. That single discipline removes most of the risk from importing mods.
