Hayati & Lost Mary Tax Guide

Hayati & Lost Mary Prices 2026: UK Vape Tax Guide

Hayati and Lost Mary are two of the most popular vape brands on Ninja Vapes, and both are directly affected by the UK's new Vaping Products Duty (VPD), which takes effect on 1 October 2026. This guide walks through exactly how the duty is calculated, what it means for specific Hayati and Lost Mary devices based on their actual e-liquid capacity, and where current pricing stands for both ranges.

We won't promise you fixed post-tax prices anywhere in this article - retailers set their own pricing, and how much of the duty gets passed on is a decision each seller makes individually. What we can show you is the maths behind the duty itself, applied to real Hayati and Lost Mary product specifications, so you understand why some devices in each range are more exposed to the new tax than others.

The Vaping Products Duty: A Quick Recap

This last point matters a lot for comparing Hayati and Lost Mary specifically, because puff count alone doesn't tell you how exposed a device is to the new duty - a device's actual e-liquid volume does. A 25,000-puff device and a 6,000-puff device from the same brand can carry very different amounts of liquid depending on how the pod or tank system is engineered, which is exactly where this guide can help.

How Much E-Liquid Is Actually in Your Device?

Puff count is a marketing figure based on the device's coil efficiency and battery life, not a direct measure of liquid volume. Here's what we can confirm for specific Hayati and Lost Mary products based on published specifications:

Devices not listed here (including the Hayati Rubik 7000, Hayati Shisha 30K, and Lost Mary BM6000 and Nera 30K kits) don't have a confirmed total e-liquid volume published in the specifications we could verify - check the individual product page for exact capacity before relying on a duty estimate for these specific devices.

Hayati: Duty Impact by Device

Using the confirmed e-liquid volumes above, here's the actual duty that will apply to each Hayati device from 1 October 2026, calculated directly from the £2.20-per-10ml rate:

The pattern here is clear: the Pro Ultra Plus 25K's dual-tank system, while offering the highest puff count, also carries by far the most duty of the Hayati devices we could confirm volumes for - more than ten times the duty of the compact S1 1K. If keeping duty exposure low matters more to you than puff count, the smaller-volume devices in the range are structurally better positioned, even though they're rated for far fewer puffs.

Lost Mary: Duty Impact by Device

The same calculation applied to confirmed Lost Mary products:

Lost Mary's Nera 15K pod carries exactly the same duty as Hayati's Pro Max Plus 6K kit - both use a 2ml pod plus 10ml refill container, so both add £2.64 in duty despite being different brands and different puff ratings. This is the clearest illustration of why puff count is the wrong number to compare when thinking about the new tax: e-liquid volume is what actually determines the duty, and two devices with very different puff counts can carry an identical tax impact if their liquid capacity matches.

Which Format Minimises Duty Exposure?

What Happens to These Prices After 1 October?

We can't tell you exactly what Hayati and Lost Mary products will cost after the duty takes effect - that's a decision Ninja Vapes and every other UK retailer makes independently, based on how much of the new duty is absorbed versus passed on to customers. What we can say with confidence is the underlying maths: a device with 22ml of e-liquid will always carry roughly five times the duty of a device with 4ml, regardless of which retailer sells it or what final price they settle on. If you're trying to predict which products are likely to see the biggest price movement, liquid volume - not brand or puff count - is the number to watch.

It's also worth remembering that retailers can continue selling existing unstamped stock until 31 March 2027, so pre-duty pricing on some Hayati and Lost Mary stock may still be available for months after the October deadline, depending on how quickly existing inventory sells through.
