Vaping in South Korea: is it legal, and what can you bring? (2026)

The English-language Korea Customs Service pages put the e-cigarette liquid in the same allowance line as cigarettes: 200 cigarette sticks, and e-cigarette liquid nicotine of 20 ml with a nicotine percentage of less than 1 percent. Both sit alongside the general US$800 exemption for other goods. Cigarette numbers and the rest of the tobacco rules are on the South Korea rules page.

Two details matter for a vape. The allowance is for liquid, not devices, and the pages do not give a device limit. And the nicotine strength is capped by the wording "less than 1 percent", which a bottle of stronger liquid would exceed. We have not seen a published translation of that wording into milligrams per millilitre, so check the label before you pack.

A revision of the Tobacco Business Act took effect on 24 April 2026. According to Busan City it widens the definition of tobacco to products containing tobacco or nicotine in any form, which pulls in synthetic-nicotine liquid that sat outside the rules before. An industry report on the amendments says they also affect the sale of e-cigarettes and nicotine pouches and refer to a new Tobacco Harm Management Act; the details are not confirmed.

For a visitor the practical effect is on where you vape. Busan said a two-month guidance period would end and that from 24 June 2026 people using these liquids in designated no-smoking areas may be fined up to KRW 100,000 under the National Health Promotion Act. We only found Busan's announcement, not one from other cities.

Treat a vape as a cigarette. The Busan announcement applies the National Health Promotion Act to synthetic-nicotine liquid in designated no-smoking areas, with a fine ceiling of KRW 100,000. Seoul is also planning to make the whole 8.12 km Cheonggyecheon stream walkway a no-smoking and no-drinking zone, with district officers able to fine on the spot; no start date had been set and the report does not say whether vapes are included.

At airports, our data marks vaping as limited at Incheon, Gimhae and Cheongju and unknown at Gimpo and Jeju, without further detail, so ask or look for a signed smoking room rather than assuming. Connecting passengers who stay airside are not entering the country; for the cabin rules on the next flight, see flying with a vape.

Heated tobacco is a legal tobacco product in Korea and is sold widely. What the English customs pages do not give is a stick allowance: cigars, loose tobacco and heated tobacco sticks are not listed there. Some legal-text sites and consumer sites quote 200 sticks, but we found no Korea Customs Service page that states it, so we do not state it as the rule. If you carry sticks, ask Korea Customs Service before you travel.

Nicotine liquid and devices are sold in Korea, and with the April 2026 revision synthetic-nicotine liquid is meant to be regulated like other tobacco. We found no source on what that means for a visitor's purchase. The industry report says the amendments affect nicotine pouches; we could not confirm how.
