VapeWholesaleHubMods Quality Control: Tests We Run Before Dispatch — Container-Scale Orders
Most first time importers of mods ask the same five questions. This page answers them in the order they usually arrive, with the numbers we quote internally rather than round marketing claims.
The Specification That Matters
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 | Open system |
|---|---|
| Resistance band | 0.8 - 1.0 ohm |

| Puff count method | Declared by capacity |
| Master carton | 120 units |
| Carton weight | 10.3 kg |
| Shelf life | 24 months |
| Storage | 15-25 C, dry, away from direct light |
Modelling a Healthy Margin
Compare mods quotes on the same incoterm. A price that looks better because it excludes a cost you assumed was included is not a saving at all.
Indicative reference points for planning purposes: entry tier from USD 2.35 per unit at 500 units, mid tier at USD 1.85, and volume tier at USD 1.35 for full container quantities. These figures move with specification, packaging and freight, so treat them as a shape rather than a quote.
How Mods Batches Are Checked
Keep a photo record of every mods approval sample. Written descriptions age badly; a dated photograph next to a delivered unit settles most arguments in seconds.
Train whoever receives mods 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.
- Model landed cost, not ex-works price, when comparing quotes.
- Plan the switch from air to sea freight before you need it.
- Write the complaint threshold into the order terms.
- Ask how the factory measures puff count, then compare like with like.
- Check carton dimensions against your freight quote before confirming.
Getting Mods to Your Warehouse
Consolidating mods 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.
Trends Worth Watching
The most durable mods lines over the last few years have been unglamorous and consistent. Novelty sells once; reliability sells every month.

Practical Checklist
- Agree the tolerance band in writing before approving artwork.
- Keep sealed retained samples from every production batch.
- Check carton dimensions against your freight quote before confirming.
- Confirm the current customs classification with your own broker.
- Plan the switch from air to sea freight before you need it.
- Rotate stock by batch code rather than by delivery date.
Frequently Asked Questions
What does a sample pack usually include?
A typical mods sample pack covers the strengths or variants you are most likely to list, packed so you can evaluate them side by side. Tell us which lines you are considering and we will match the pack to that rather than sending a generic selection.
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.
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 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.
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.
