Nicotine Strengths Explained: From 0mg to 20mg and What They Mean
Nicotine strength is the most misunderstood spec line in the category. Two numbers — mg/mL and total mg — tell different stories, and the form (salt or freebase) changes everything about how the strength feels. A trade buyer who understands the vocabulary can explain any device to any customer — and the TGA’s 20mg/mL cap is the regulatory ceiling that frames the whole conversation.
mg/mL versus total mg: two numbers, two stories
The spec sheet states two numbers: mg/mL (concentration: milligrams of nicotine per millilitre of e-liquid) and total mg (the absolute amount in the whole tank). An 18ml tank at 20mg/mL contains 360mg total; an 18ml tank at 0mg/mL contains zero. The concentration sets the per-draw feel; the total sets the tank’s overall delivery — and a customer who reads only one number misunderstands the device.
The trade translation: mg/mL is the spec a customer feels; total mg is the spec a regulator cares about. The HERC’s spec sheet states both clearly — and the TGA’s 20mg/mL cap is the ceiling the concentration cannot exceed.
Salt versus freebase: why the form matters
Nicotine comes in two forms. Freebase nicotine is the alkaloid base: it hits sharper, absorbs more slowly and irritates the throat at higher concentrations. Nicotine salt is the freebase bound to a mild acid (usually benzoic or salicylic): it hits smoother, absorbs faster and tolerates higher concentrations without irritation. The form changes the feel of the same mg/mL — 20mg/mL salt feels smoother than 20mg/mL freebase.
The HERC’s e-liquid uses salt nicotine for the Australian trade: the smoother delivery suits the TGA’s 20mg/mL cap, and the faster absorption suits the disposable format’s draw pattern. Our salt nicotine explainer covers the chemistry in detail.
The TGA cap: 20mg/mL and what it means
Australia’s TGA framework caps nicotine concentration in vaping products at 20mg/mL for adult access through pharmacy channels. The cap is a regulatory ceiling, not a recommendation — and it frames every conversation about strength in the Australian market. A device sold above 20mg/mL is not lawful for general supply, and a trade buyer operating in Australia should verify that every device they stock is within the cap.
The HERC’s strength is tuned for the Australian market: at or below the 20mg/mL cap, using salt nicotine for smooth delivery and fast absorption. The spec sheet states the strength clearly — and the compliance documentation is available for trade buyers who need it.
Zero-nicotine: the 0mg option
Zero-nicotine devices (0mg/mL) are a growing segment: they deliver the draw, the flavour and the ritual without the nicotine. For a trade buyer, the 0mg option is a positioning tool: it serves customers who want the experience without the compound, and it is not subject to the TGA’s nicotine pharmacy-channel requirements in the same way. Our zero-nicotine guide covers the state-by-state rules.
The honest positioning: 0mg is not a “healthier” option — it is a different option. A shelf that stocks both nicotine and zero-nicotine devices serves the full market honestly; a shelf that stocks only nicotine devices serves only part of it.
Nicotine Strength Decoder
| Strength (mg/mL) | Form | Feel | TGA status (AU) | Best customer |
|---|---|---|---|---|
| 0 mg/mL | N/A (no nicotine) | Flavour and vapour only | Not subject to nicotine rules | Ritual seekers, non-users |
| 5 mg/mL | Salt | Mild, smooth | Within 20mg/mL cap | Light users, social |
| 10-15 mg/mL | Salt | Moderate, smooth | Within 20mg/mL cap | Moderate daily users |
| 20 mg/mL | Salt | Full, smooth (cap ceiling) | At regulatory cap | Heavier users (cap-limited) |
| 20+ mg/mL | Freebase or salt | Stronger, harsher | Not lawful for general supply (AU) | Not for Australian shelves |
Frequently Asked Questions
What does 20mg/mL mean on a vape spec sheet?
20 milligrams of nicotine per millilitre of e-liquid — the concentration. In an 18ml tank, that is 360mg total. The concentration sets the per-draw feel; the total sets the tank’s overall delivery. In Australia, 20mg/mL is the TGA’s regulatory cap for nicotine vaping products supplied through pharmacy channels.
What is the difference between salt and freebase nicotine?
Salt nicotine is freebase bound to a mild acid: it hits smoother, absorbs faster and tolerates higher concentrations. Freebase is the alkaloid base: it hits sharper, absorbs more slowly and irritates at higher concentrations. The same mg/mL feels different in each form — and the HERC uses salt for smooth delivery within the TGA cap.
Is 20mg/mL the maximum strength allowed in Australia?
Yes, for nicotine vaping products supplied through pharmacy channels under the TGA framework. Devices above 20mg/mL are not lawful for general supply in Australia. Trade buyers should verify that every device they stock is within the cap and carries the appropriate compliance documentation.
Are zero-nicotine vapes regulated the same way?
Zero-nicotine devices (0mg/mL) are not subject to the TGA’s nicotine pharmacy-channel requirements in the same way — but state and territory rules vary. They serve customers who want the experience without the compound, and a shelf that stocks both serves the full market honestly. Verify current state rules before stocking.
