VapeWholesaleHubSpotting Defects in Mod Before Shipment — Replenishment Cycles
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.
What to Fix Before Approving Mod
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.
| Product category | Refillable kit |
|---|---|
| Resistance band | 1.2 - 1.4 ohm |
| Capacity tolerance | +/- 2% |
| Puff count method | Machine cycle 2s on / 18s off |
| Master carton | 120 units |
| Carton weight | 4.7 kg |
| Shelf life | 18 months |
| Storage | 15-25 C, dry, away from direct light |
Pricing and Margin
When mod input costs move, ask which component moved. A generic price increase hides whether you are paying for cells, packaging or simply a busy production calendar.

Indicative reference points for planning purposes: entry tier from USD 2.30 per unit at 500 units, mid tier at USD 0.73, and volume tier at USD 1.04 for full container quantities. These figures move with specification, packaging and freight, so treat them as a shape rather than a quote.
Turning Mod Into Repeats
Put mod where the decision is made, not where the margin is highest. In most stores that means near the counter or at eye level in the category, rather than wherever there is spare space.
Positioning Mod on Your Shelf
One useful exercise: list every mod line you stock and mark the last date each one sold at full price. Anything without a recent full price sale is taking space from something that would use it better.
How Mod Batches Are Checked
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.
- Ask how the factory measures puff count, then compare like with like.
- Confirm the current customs classification with your own broker.
- Model landed cost, not ex-works price, when comparing quotes.
- Check carton dimensions against your freight quote before confirming.
- Rotate stock by batch code rather than by delivery date.
Practical Checklist
- Start with a mixed carton and let your own sell-through decide.
- Ask how the factory measures puff count, then compare like with like.
- Rotate stock by batch code rather than by delivery date.
- Write the complaint threshold into the order terms.
- Agree the tolerance band in writing before approving artwork.
- Model landed cost, not ex-works price, when comparing quotes.
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.
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.
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.
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.
How do you handle a short shipment?
Cartons are counted and weighed before dispatch and the figures are shared with you. If something is short on arrival, the packing record and the carrier documentation are both available, which keeps the claim straightforward.
Next Step
If you are comparing options right now, send us the specification you have been quoted elsewhere. A side by side reading usually shows where the price difference actually comes from, and that is the most useful first conversation to have.
