Every retailer asks this question and almost nobody can answer it with data, because strength-level sales are the one number the industry keeps to itself. Brands publish ranges, retailers publish assortments, and scanner data sits behind paywalls. What exists in the open is thinner and more interesting: wholesalers' stocking guides, retailer catalogues and what manufacturers admit on earnings calls. This page assembles those three sources, states what each can and cannot support, and draws the ranging conclusion they jointly point to. It is the hub of the Snus Watch trade cluster, alongside the category share tracker and the white label vs private label explainer.
One ground rule first. Pouches are adult products, sold to adults: 18 and over in Europe and the UK, 21 and over in the US. This page is trade analysis of published evidence, not a stocking instruction for any brand.
What evidence exists about which strengths sell?
Three kinds, each with a stated weakness. Wholesaler guides describe what moves through their warehouses and what they advise retailers to stock; they are commercially interested but operationally close to the shelf. Retailer catalogues show what is actually ranged, which is supply, not sales, though assortments that persist across seasons usually persist because they rotate. Earnings commentary is the only source with real numbers behind it, and it arrives as admissions: a manufacturer naming the segment it is losing is telling you where demand is growing.
Nothing public gives unit sales by strength band for a whole market. Any page that quotes one should be asked for its source. The strength guide decodes what the bands themselves mean on a can; this page is about which bands move.
What does the wholesaler evidence say?
UK Vaper Wholesale, a UK wholesaler, publishes a nicotine strength guide with its pouch range, and it is unusually explicit about velocity by tier:
| Tier (wholesaler's bands) | Mg per pouch | Wholesaler's note |
|---|---|---|
| Low | 3 to 6 | Lower-strength buyers; performs well online rather than at the counter |
| Medium | 8 to 12 | The bestseller band; "this and high strength dominate retail sales across all formats" |
| High | 15 to 20 | Fast-moving in retail alongside medium |
| Extra strong | 20 and up | High-tolerance niche; small, extremely loyal customer base |
Their retailer insight, in their words, is that medium and high strengths sell the fastest in most retail environments, and low-strength options tend to perform better online. Read it as a European-style shelf speaking: in markets where the full ladder is legal and ranged, the middle and upper-middle do the volume, the bottom of the ladder migrates to e-commerce, and the top is a loyalty niche rather than a volume line.
Why does the US shelf look different?
Because the US shelf was built by authorization, not by ranging. The FDA-authorized ZYN line is ten flavours at 3 and 6 mg, and ZYN holds roughly 57 percent of US retail value in the category, so the centre of the American shelf sits at strengths the European guide calls low. US retailer catalogues show the pattern: the leading brands cluster at 3 and 6 mg, with a challenger tier at 9 to 15 mg building around them.
The direction of travel, though, matches Europe's. On PMI's Q2 2026 earnings call, management attributed recent category share softness partly to "competitive gaps in the growing higher strength segment", and answered it in June 2026 with ZYN Ultra, moist pouches at 9 and 11 mg, with 1.5 mg and 8 mg dry variants announced for the third quarter. When the dominant brand in a 3-and-6 market launches upward and downward at once, it is mapping the two ends it believes are growing: headroom above its core, and an entry rung below it.
How do format and channel change the answer?
Channel first. Online retail carries depth cheaply: a web shop can list every rung of every brand and let the tail sell at its own pace, which is why low strengths, bought deliberately by people managing their intake, perform there. A physical shelf pays rent per facing, so in-store ranging compresses onto the rungs that rotate weekly, and the tail gets cut. The same market therefore has two correct answers, one per channel, and ranging them identically is the common error.
Format second. Moist and dry pouches at the same printed strength are different products in the hand, and the US higher-strength build-out has arrived in moist formats first, Ultra included. Retailers reading strength data across formats should remember that the printed figure is per pouch and comparable, while rotation is a property of the specific product, a point the mg per pouch vs mg per gram conversion makes in label terms.
What does a defensible strength mix look like?
From the evidence above, and no further:
- European-style shelves: core facings in the 8 to 12 mg band, a real presence at 15 to 20 mg, low strengths held mainly for the online channel, and a small, deliberate extra-strong facing for the loyal niche rather than a whole shelf of it.
- US shelves: the 3 and 6 mg core that the authorized leaders built, with the 9 to 12 mg challenger tier ranged as the growth bet the manufacturers themselves are making, and entry rungs watched as new variants land.
- Everywhere: judge the mix on your own sell-through by rung each quarter, and cross-check it against the category numbers in the share tracker. Wholesaler guidance is a prior, not a result.
FAQ
Which single strength sells the most?
No public source answers at that resolution, and the honest sources answer in bands. The wholesaler evidence names 8 to 12 mg as the bestselling band in-store in its market; the US market's volume concentrates at 3 and 6 mg because its authorized leaders sell there. Anyone quoting one magic milligram for all markets is extrapolating past the evidence.
Do low strengths sell at all in physical stores?
Yes, but the wholesaler guidance is that they rotate better online. In the US they are the core, which shows the rule is about market structure, not about the strengths themselves: where the big brands sell low, low is what the shelf sells.
Why do online and in-store strength sales differ?
Shelf economics. Online listings cost almost nothing to keep, so deliberate, low-frequency purchases survive there. In-store, each facing must earn its space weekly, so ranging compresses onto the fastest rungs and the tail is delisted, whatever its merits.
How often should a retailer review the strength mix?
Quarterly fits the available evidence cycle: wholesaler guidance shifts slowly, while the category data that can confirm or contradict it arrives with earnings season. The tracker in this cluster updates on the same rhythm.
