Whether the production and sale of fruit-flavored Vape necessarily constitute counterfeit products depends on the substantive criteria for determining "counterfeit products"—namely, quality and performance. In practice, these criteria are evaluated through physicochemical indicators such as active substance content, mechanical strength, or safety performance standards.
1. Nicotine Concentration and Total Nicotine Content
Nicotine (or tobacco alkaloids) is a crucial component of fruit-flavored Vape. While nicotine in controlled amounts does not necessarily harm health and is even used in medical applications, excessive levels can lead to addiction and health risks. According to national e-cigarette standards, nicotine concentration should not exceed 20 mg/g, and the total nicotine content should not surpass 200 mg/g. If testing reveals nicotine levels exceeding these limits, the product may be classified as counterfeit.
However, some e-cigarette products may not contain nicotine at all. In practice, certain jurisdictions argue that the presence or absence of nicotine does not determine whether a product is counterfeit, and thus do not test for it. I contend that while nicotine content may affect whether a product qualifies as an e-cigarette or tobacco product, it is not a mandatory criterion for counterfeit classification. Nevertheless, if nicotine is present, its concentration is a key factor in determining product quality. Therefore, if a product contains nicotine but no component testing is conducted, the basis for deeming it counterfeit is insufficient.
2. Detection of Additives: WS-23 and Diacetyl
In cases involving fruit-flavored Vape, the most frequently tested substances are N,2,3-trimethyl-2-isopropylbutyramide (WS-23) and 2,3-butanedione (diacetyl). These additives play a significant role in Vape:
WS-23 is a cooling agent commonly used to provide a minty or icy sensation.
Diacetyl is a flavoring agent used to enhance creamy or buttery notes.
Both substances are essential in e-cigarette formulations. However, excessive amounts can pose respiratory risks. National standards stipulate:
WS-23 should not exceed 10 mg/g.
Diacetyl should not surpass 22 mg/kg.
For example, in a case I handled, WS-23 levels were specifically tested to determine compliance.

3. Detection of Heavy Metals and Arsenic Contaminants
Beyond nicotine and flavoring agents, e-cigarette liquids may contain impurities such as heavy metals (e.g., lead, cadmium, mercury) and arsenic. However, in practice, provincial tobacco quality inspection stations often focus only on nicotine, WS-23, and diacetyl, rarely testing for contaminants.
This is because, under current standards, any single violation (e.g., incorrect labeling, missing warnings, or prohibited additives) can classify an e-cigarette as counterfeit—even without full component analysis. Consequently, some inspections skip chemical testing altogether, relying instead on packaging non-compliance to declare products counterfeit.
Conclusion
To determine whether fruit-flavored Vape are counterfeit, component testing is essential. In practice, the primary substances analyzed include:
Nicotine (if present),
WS-23 and diacetyl (common flavoring agents),
Heavy metals and arsenic (though rarely tested).
If no chemical analysis is performed, there is insufficient evidence to prove that the product is inherently defective in quality or performance.
