In the current UK regulatory environment, product structure and compliance are key considerations for products entering the market. The newly launched Hayati® Pro Max+ 4K has joined Hayati®’s compliant product range, introducing a new 4K option to the Hayati® Pro Max+ series.
The product features a 1.5 mL pod and 5.5 mL refill container, while the device itself is rechargeable. It is defined by three key features: replaceability, refillability and rechargeability, referred to here as the “3R” principle. Together, these create a reusable product structure that differs from traditional single-use devices.
Replaceable and Refillable Pod
Hayati® Pro Max+ 4K features a 1.5mL pod that can be both replaced and refilled. Once the pod reaches the end of its usable life, users can replace it with a new one without replacing the entire device. During use, the 5.5mL refill container refills the 1.5mL pod and supports continued use.

Rechargeable Device
Hayati® Pro Max+ 4K features a rechargeable device that can be recharged when the battery runs low and then used again. Together with its replaceable pod and refill container, this completes the product’s replaceable, refillable and rechargeable "3R" structure.
A Product Solution for the Vape Tax
The launch of Hayati® Pro Max+ 4K also responds to changing needs in the UK Tax environment. Compared with Hayati® Pro Max+ 6K, the 4K uses a smaller 1.5mL pod + 5.5mL refill container. While retaining the familiar Hayati® Pro Max+ experience, it provides a more duty-friendly option for users who are increasingly mindful of vape-related costs.

Hayati® Pro Max+ 4K brings the familiar 4K format back with an entirely new product structure, becoming the latest compliant addition to the Hayati® product range.
