Top Takeaways:
- South Korea has closed its synthetic-nicotine loophole by classifying synthetic liquid e-cigarettes as “tobacco” under the Tobacco Business Act.
- The change relocates 95% of the liquid-vape market under taxation and unified public-health controls, with officials estimating ₩930.1 billion in new annual revenue.
- The reform passed with bipartisan support after years of stalled attempts dating back to 2016, marking a significant shift in Korea’s regulatory approach to modern nicotine products.
It’s been nearly 10 years. South Korea’s National Assembly approved a significant amendment to the Tobacco Business Act on Tuesday, officially classifying liquid e-cigarettes with synthetic nicotine as “tobacco’—a move that closes one of the country’s most controversial regulatory gaps and brings the rapidly growing synthetic segment under full taxation and health regulations.
The reform, passed on December 2 as part of a broader package of 79 livelihood-related bills and 16 budget items, effectively closes a long-standing gap that allowed synthetic-nicotine products to be sold and consumed outside the country’s tobacco regulations. Government officials noted that synthetic nicotine now accounts for an estimated 95% of the domestic liquid-vape market, yet until now, it faced none of the excise taxes, licensing requirements, or unified public health rules that apply to conventional tobacco or nicotine-extracted products.
By including synthetic liquids under the Tobacco Business Act, lawmakers aim to generate approximately 930.1 billion won (US$632 million) in new tax revenue once the system is fully implemented. Health authorities and economic committees have argued for years that synthetic-nicotine products should be treated the same as traditional nicotine sources, calling the regulatory gap outdated and damaging to both fiscal and public health objectives.
Attempts to pass the measure date back to 2016, but repeated efforts were blocked in committee or stalled before floor votes, with officials citing strong opposition from parts of the vaping industry. This week’s plenary approval marks the first time the reform has passed both the Political Affairs Committee and the broader Assembly with bipartisan support, reflecting growing concern over youth uptake, tax leakage, and uneven safety controls in South Korea’s rapidly changing nicotine market.
The recently passed amendment authorizes the government to impose excise taxes, require market authorization and compliance filings, mandate ingredient disclosures, and enforce advertising and packaging restrictions on synthetic-nicotine liquids in the same way as other tobacco products. It also enables the Ministry of Economy and Finance and the Ministry of Health and Welfare to close the enforcement gap that regulators claim has distorted competition between legal tobacco manufacturers and companies operating in the synthetic-nicotine sector.
Officials highlighted that the regulatory change is part of a larger government effort to standardize nicotine-product regulation and stop manufacturers from avoiding taxes by switching to chemically synthesized ingredients. With synthetic products now clearly included in the definition of “tobacco,” South Korea joins a small group of countries updating definitions to keep up with technological advances in the nicotine industry.
The government has not yet announced the exact implementation schedule, but tax authorities are expected to start preparatory steps immediately to incorporate synthetic liquids into the existing excise system. Industry groups are waiting for detailed guidance on transitional periods, reporting requirements, and compliance deadlines.
