As a tobacco alternative product directly targeting adult consumers, e-cigarettes are sold through various channels including offline specialty stores, convenience stores, mall counters, and online e-commerce platforms, constituting a segment of the fast-moving consumer goods (FMCG) market.

In some countries and regions (e.g., the UK), e-cigarettes are officially recommended by health authorities as smoking cessation aids to help smokers reduce or quit traditional cigarettes, forming part of tobacco harm reduction strategies.

This encompasses the entire manufacturing supply chain of e-cigarettes, including e-liquid formulation, battery production, atomizer and device assembly, and packaging. It is a manufacturing branch that integrates sectors like electronics, chemicals, and precision engineering.

E-cigarette products integrate microelectronics, electro-thermal conversion, aerodynamics, and software control (e.g., power adjustment). They belong to the innovative consumer electronics category, focusing on user experience and technological iteration.

Due to highly concentrated production (primarily in China) and a globally distributed consumer market, international trade of e-cigarettes is highly active, involving specialized services such as cross-border logistics, customs compliance, and warehousing & distribution.
