Nicotine 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.
Reading a Nicotine Spec Sheet
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 | 0.6 - 0.8 ohm |
| Capacity tolerance | +/- 3% |
| Puff count method | Declared by capacity |
| Master carton | 200 units |
| Carton weight | 4.9 kg |
| Shelf life | 24 months |
| Storage | 15-25 C, dry, away from direct light |
Logistics That Protect Margin
Customs classification for nicotine varies by market and changes from time to time. We ship with full documentation, but your broker should confirm the current code before your first order rather than after it lands.
Merchandising and Listing Tips
Online, shoot nicotine at a consistent scale across the range. Customers compare by eye, and inconsistent product photography creates returns that have nothing to do with the product.

How Nicotine Batches Are Checked
AQL sampling gets a lot of attention, but for nicotine the more useful habit is simply measuring the same three things on every single batch. Trend lines catch problems that pass/fail checks miss.
Random checks are fine, but weight the sample towards the start and end of a nicotine production run. Those are where a line is most likely to drift.
- Write the complaint threshold into the order terms.
- Check carton dimensions against your freight quote before confirming.
- Agree the tolerance band in writing before approving artwork.
- Model landed cost, not ex-works price, when comparing quotes.
- Start with a mixed carton and let your own sell-through decide.
Trends Worth Watching
Retailers report that nicotine customers are asking more specific questions than they did two years ago. That favours ranges with clear, simple information over ranges with clever marketing.
Pricing and Margin
When you model nicotine pricing, build in a realistic shrink figure. Even a well run line loses a small percentage to damage, expiry and sampling. Pretending that number is zero is how a healthy looking margin turns negative.
Indicative reference points for planning purposes: entry tier from USD 2.39 per unit at 1000 units, mid tier at USD 0.92, and volume tier at USD 1.32 for full container quantities. These figures move with specification, packaging and freight, so treat them as a shape rather than a quote.
Practical Checklist
- Model landed cost, not ex-works price, when comparing quotes.
- Keep sealed retained samples from every production batch.
- Check carton dimensions against your freight quote before confirming.
- Write the complaint threshold into the order terms.
- Agree the tolerance band in writing before approving artwork.
- Start with a mixed carton and let your own sell-through decide.
Frequently Asked Questions
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 I only need a small first order?
That is normal and sensible. A mixed carton lets you test nicotine in your own market before committing to a production run, and the specification you approve at that stage carries through to larger orders unchanged.
Can you match an existing product I already sell?
Often yes, provided we can measure it properly. Send a physical sample and we will report back on what can be matched, what will differ slightly, and why. An honest gap is more useful than a vague promise.
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.
Can I visit the production facility?
Yes, and we encourage it for larger programmes. Visits are most useful when you already have a draft specification, because you can then check the specific processes behind the numbers you care about.
Next Step
Send us your current nicotine specification even if you are not planning to move suppliers. A second read of a document you use every month is usually worth the ten minutes.
