South Korea to Bring Nicotine Vapes Under Tobacco Rules From April 24

New Rules Close the Synthetic Nicotine Gap

South Korea will bring nicotine vaping liquids under its tobacco control framework on April 24, 2026, expanding the legal definition of tobacco for the first time in 37 years. The revision to the Tobacco Business Act will subject liquid electronic cigarettes to the licensing, packaging, advertising and public smoking restrictions applied to conventional cigarettes.

As of April 20, manufacturers, importers, retailers and users have four days before the change takes effect. The Ministry of Health and Welfare says compliance inspections will begin on April 24, covering businesses that produce, import or sell the products.

The central change concerns where nicotine comes from. The existing law defines tobacco products as items made from tobacco leaves and manufactured for smoking, sucking, inhaling vapor, chewing or sniffing. Nicotine produced in laboratories falls outside that definition because it does not come from tobacco leaves.

The revised definition covers products made from tobacco or nicotine, regardless of the nicotine's source. Synthetic nicotine liquids will consequently enter the regulatory framework that already governs conventional tobacco products. Nicotine vaping products will also become subject to the National Health Promotion Act.

Synthetic nicotine products have spread through online platforms and unmanned shops while escaping tobacco taxes, licensing requirements and advertising restrictions. Manufacturers and retailers have been able to sell flavored products with limited oversight because the law classified products by their ingredients' origin rather than simply by whether they contained nicotine.

The reform arrives as vaping becomes more common among adults and young people. It also comes amid concerns about age checks at automated shops and the use of vaping equipment to consume illegal drugs. The changes address nicotine liquids, while the electronic devices themselves and other liquids used with them remain a separate concern.

What Changes on April 24?

The Tobacco Business Act revision removes the legal difference between nicotine extracted from tobacco leaves and nicotine synthesized in a laboratory. Businesses selling the newly covered products will need tobacco retail licenses, and manufacturers and importers will face the warning and marketing requirements that accompany tobacco classification.

Online sales of nicotine vaping products will generally be prohibited. Purchases will instead be restricted to licensed physical retailers, including convenience stores and specialty vape shops. Manufacturers and retailers will also have to operate within the taxation and distribution controls applied to conventional cigarettes.

The schedule places several changes on the same date:

• April 20, 2026: The new tobacco definition has yet to take effect, with four days remaining before implementation.
• April 24, 2026: The expanded definition takes effect, bringing nicotine vaping liquids under tobacco controls regardless of the nicotine's source.
• April 24, 2026: The Ministry of Health and Welfare plans to begin compliance inspections of manufacturers, importers and retailers.

For users, the immediate practical change is that synthetic nicotine vapes will be covered by restrictions in designated nonsmoking areas. For businesses, the change reaches beyond where a product can be sold to how it is packaged, advertised and distributed.

Vaping in Nonsmoking Areas Will Carry a Fine

Users of nicotine vapes will face fines of 100,000 won for vaping in designated nonsmoking areas once the expanded definition takes effect. That amount is approximately $68 to $86, depending on the exchange rate.

South Korea has applied conventional cigarette bans to indoor settings such as restaurants, cafes, workplaces and public transportation systems since 2015. From April 24, the newly covered nicotine liquids will fall under the same restrictions.

Authorities have frequently canceled fines after discovering that a person was using a vape rather than a conventional cigarette, because the earlier legal definition did not explicitly cover liquid electronic cigarettes. The amendment closes that enforcement gap for nicotine products covered by the revised law.

The Ministry of Health and Welfare will work with local governments to strengthen patrols and apply nonsmoking policies consistently across different jurisdictions. A vape containing synthetic nicotine will therefore carry the same public use consequences as other regulated tobacco products.

Warnings and Flavor Marketing Restrictions

Manufacturers and importers will have to display graphic health warnings and warning text on packaging and in permitted advertising. The requirements bring nicotine vaping liquids into the warning system used for conventional tobacco products.

Tobacco advertising is limited to specified channels: periodicals such as magazines, event sponsorships, the interiors of retail stores, and international aircraft and passenger ships. Businesses selling the newly regulated liquids will have to operate within those limits.

Flavor descriptions will face particular restrictions. When an e-liquid contains flavoring agents, words such as "mango," "mint" and "sweet" will be prohibited on bottles and packaging. Images suggesting fruit, candy or dessert flavors will also be banned.

Health officials say these marketing approaches have made vaping products attractive to teenagers. The rules target the way flavored liquids are presented to customers, requiring businesses to change labels and promotional materials as well as secure the necessary licenses.

Violations of the packaging and advertising rules can carry fines of up to 5 million won, approximately $3,472, or imprisonment of up to one year for severe infractions. The penalties make compliance a financial and legal issue for manufacturers, importers and sellers.

Youth Figures Put Vaping at the Center of Reform

Figures from the Korea Disease Control and Prevention Agency show that liquid electronic cigarettes became the most commonly used tobacco product among female students in grades six through eleven in 2025. Their vaping rate reached 1.54 percent, compared with 1.33 percent for conventional cigarettes and 0.32 percent for heated tobacco products.

The gap between vaping and conventional smoking among those female students was 0.21 percentage points. Heated tobacco products, which heat tobacco rather than burn it, had a substantially lower reported rate than either category.

Among young people more broadly, the vaping rate reached 2.9 percent in 2025, approaching the 3.3 percent rate for conventional cigarette use. The difference between the two rates was 0.4 percentage points.

Health officials also point to overlapping use: 61.4 percent of young smokers use both vaping products and conventional cigarettes. They say this pattern suggests that electronic cigarettes function as a gateway rather than a tool for quitting for many young users.

Adult vaping has risen as conventional smoking has declined. Vape use increased from 2 percent in 2016 to 3.8 percent in 2024, an increase of 1.8 percentage points. Conventional cigarette smoking fell from 23.2 percent in 2013 to 15.9 percent in 2024, a decrease of 7.3 percentage points.

The figures explain why the reform reaches beyond cigarettes made from tobacco leaves. Nicotine products that had fallen outside the tobacco definition were becoming more widely used during a period when conventional smoking was falling.

Unmanned Shops Face Tighter Age Controls

Unmanned stores and online platforms have made vaping products easier to obtain, adding to concerns about access among teenagers. Recent inspections found that 11 percent of electronic cigarette vending machines lacked functioning age verification devices.

Many shops operating without staff also lacked proper retailer designation or adult certification systems. Those gaps meant that access controls were missing or incomplete at some places selling vaping products.

The revised rules tighten controls on automated sales devices. Installation will be restricted to licensed retailers, with machines placed in locations where minors are prohibited, such as designated smoking rooms or areas reserved for adults.

All vending machines will need functioning technology to verify that buyers are adults. The requirements combine licensing, location restrictions and age checks, rather than relying on a machine's presence inside a shop as the only control.

For businesses that have operated without tobacco retailer designation, the revised definition changes the conditions under which nicotine liquids can be sold. For younger customers, restrictions on online sales and automated access are intended to reduce the ease of obtaining them.

Drug Seizures Reveal Another Concern

National Forensic Service figures show a sharp increase in seizures involving electronic cigarettes containing drugs and liquid narcotics. The number rose from 1,870 cases in 2022 to 3,713 in 2023 and 5,378 in 2024.

The 2024 figure was about 2.9 times the 2022 total, an increase of 3,508 cases across those two years. The figures cover electronic cigarettes containing drugs and liquid narcotics, both of which have become a concern alongside nicotine use.

Among teenage drug suspects in 2024, electronic cigarettes and liquid narcotics accounted for 146 of 506 drug seizure cases, or about 29 percent. That exceeded the 122 cases involving powdered drugs and the 38 involving syringes.

Traffickers reportedly exploit the accessibility of vaping equipment and the lower psychological barrier that electronic cigarettes can present to teenagers. Synthetic cannabis and similar substances can look like ordinary nicotine vaping liquids while lacking the distinctive smoke or odor associated with traditional marijuana. That makes them easier to conceal from parents and law enforcement.

In one documented case, a student aged 17 encountered synthetic cannabis after an adult offered her a "tasty liquid" to smoke through an electronic cigarette device. She later realized that she had been exposed to illegal drugs.

Critics say the Tobacco Business Act amendment leaves a gap because it regulates liquids containing nicotine without directly addressing electronic devices or other solvents that can be used to deliver drugs. Teenagers can still obtain vaping hardware relatively easily, and purchases of suspicious liquids could move into underground markets.

Public health experts have called for broader measures to raise barriers to electronic cigarette use among adolescents, including more education and stricter sales controls. The nicotine reform and the concerns about drug delivery involve the same equipment, but the amendment's direct focus is nicotine liquids.

What Travelers Need to Declare

Tourists and business visitors may bring personal vaping devices and e-liquids into South Korea, but the duty free allowance is limited to less than 20 milliliters of total liquid. All liquids must also contain less than 1 percent nicotine, equivalent to 10 milligrams per milliliter.

Travelers carrying 20 milliliters or more, or any liquid with a nicotine concentration of 1 percent or higher, must declare the items to customs on arrival. Failure to declare can lead to confiscation, payment of taxes and duties, and potentially substantial fines.

Authorities strongly discourage importing e-liquids containing 1 percent nicotine or more because they may be classified as chemical substances. That classification can require complex import procedures unsuitable for tourists. Liquids exceeding 2 percent nicotine face a particularly high risk of confiscation.

The volume and concentration limits are separate conditions. A traveler bringing a small bottle still needs to consider its nicotine strength, while a traveler carrying a weaker liquid needs to consider the combined volume of all bottles.

Flight Packing and Airport Checks

Vaping devices containing lithium-ion batteries must travel in hand luggage. They are strictly prohibited in checked baggage because of fire safety rules.

E-liquids are best packed in checked luggage to avoid problems with the liquid limits applied to hand luggage. Bottles should be sealed in plastic bags to prevent leakage.

Customs officials at major airports, including Incheon International, Gimhae and Gimpo, enforce import requirements through random X-ray scans and inspections. Travelers must consider customs restrictions separately from the rules governing where devices and liquids are packed for a flight.

Passing through the Green Channel, which is for passengers with nothing to declare, while carrying restricted items can bring additional consequences. Penalties increase by 40 to 60 percent for an untruthful declaration.

A personal device can therefore be permitted for travel while the liquid carried with it still requires declaration or faces import restrictions. The battery rules govern flight safety, while the liquid limits govern entry into South Korea.

A Regulatory Change for a $16 Billion Market

South Korea's tobacco market is valued at approximately $16 billion. Electronic cigarettes accounted for 13 percent of the market by sales as of the middle of 2019, and the country was the world's second largest market for heated tobacco products after Japan.

The expanded tobacco definition will change the operating conditions for manufacturers and retailers that have sold synthetic nicotine products outside conventional tobacco controls. Licensing, taxation and distribution requirements will now apply alongside restrictions on advertising and sales channels.

Taxation rates on nicotine e-liquids already equal or exceed 50 percent of those applied to conventional cigarettes, with historical trends showing that those rates have increased over time. Bringing synthetic nicotine into the tobacco definition closes the gap that allowed those products to escape tobacco taxation.

Product standards also form part of the regulatory framework. Manufacturers face requirements under the Consumer Product Safety Act for items without nicotine, or tobacco product standards for devices containing nicotine.

The government has presented the changes as consistent with the World Health Organization Framework Convention on Tobacco Control. Delegates at the 11th Conference of the Parties adopted resolutions in 2025 to regulate all types of tobacco products, specifically addressing challenges posed by new and emerging nicotine products.

A Ministry of Health and Welfare official described the revision as establishing a youth smoking prevention network that meets international standards. The official presented the legislation as a cornerstone for reducing tobacco exposure among future generations and moving toward a generation free of tobacco.

April 24 will bring the immediate legal change: nicotine liquids will be covered regardless of whether their nicotine came from tobacco leaves or a laboratory. Its practical reach will extend from retail licenses and labels to age checks, online sales and fines in designated nonsmoking areas.
