8543.40.00.30 - With substances containing nicotine

This HTS category, 8543.40.00.30, specifically covers electronic cigarettes and similar personal electric vaporizing devices that are designed to function with substances containing nicotine. These devices typically consist of a battery-powered heating element that vaporizes a liquid or solid substance, which is then inhaled by the user. The defining characteristic for inclusion in this sub-heading is the presence of nicotine within the substance being vaporized.

This category is distinguished from its sibling, 8543.40.00.40 "Other," by the explicit mention of nicotine. While both categories fall under electronic cigarettes and similar personal electric vaporizing devices, the "Other" sub-heading would encompass devices that vaporize substances *without* nicotine, such as those used for aromatherapy or the vaporization of other non-nicotine liquids. Therefore, the presence or absence of nicotine in the vaporizable material is the key differentiator.

As this is a leaf node in the HTS classification, there are no further subcategories. Classification is determined solely by the nature of the device and its intended use with nicotine-containing substances. Examples of goods that would fall under this category include electronic nicotine delivery systems (ENDS) and other personal vaporizers where the consumable substance is specifically formulated to contain nicotine.
