Packing for Korea: Plugs, Power Banks, Medicine and What You Cannot Bring In

Pre-departure checklist · Customs & quarantine rules · Checked 2026-08-23

Most packing mistakes for Korea are not about forgetting something. They are about bringing something that is not allowed: a power bank in the wrong bag, a cold medicine with a controlled ingredient, a bag of beef jerky, or fresh fruit from the last stop. This guide lists what Korean authorities actually say about each of those, with the official source behind every rule.

The rules below are from Korea Customs Service (KCS), the Ministry of Food and Drug Safety (MFDS), the Animal and Plant Quarantine Agency (APQA), the Ministry of Land, Infrastructure and Transport (MOLIT) and Incheon Airport, as checked on 2026-08-23. Rules change; when in doubt, check the official site before you fly.

Electricity: 220V, 60Hz, round two-pin sockets

Korea uses 220 volts at 60 Hz, and the wall outlet has two round holes (the European-style Type C / Type F shape). The Korea Tourism Organization notes that if you do not have a multi-voltage travel adapter, you can ask your hotel front desk to lend or sell one, or buy one at the airport, retail stores, duty-free shops and convenience stores.

A small multi-port USB charger plus one adapter is usually enough for a short trip. For seasonal clothing, see /guide/seasons-and-packing.

Power banks and phone charging on the plane

Korea tightened its in-flight rules for portable batteries in 2025, and tightened them again in 2026. The current MOLIT rules, as published on the government policy portal on 2026-04-08, are:

Your airline may apply its own version of these rules, so check your airline's notice too. Practical tip: check the Wh rating printed on your power bank before you pack. MOLIT's own conversion treats 160Wh as roughly 43,000mAh, so a typical 10,000–20,000mAh bank is well inside the limit.

Medicine: what to carry and what needs a permit

Ordinary prescription medicine for personal use is normally fine to bring in. The problem is medicine that contains a substance classed as a narcotic or psychotropic under Korea's Narcotics Control Act — including some common cold and cough medicines sold over the counter elsewhere.

Controlled ingredients named by Korea Customs

Korea Customs Service publishes a warning page listing ingredients that make a medicine a controlled drug in Korea. Ingredients on that page include:

The same KCS page gives examples of products that have been caught at customs, such as DayQuil, NyQuil, Robitussin, Sudafed, Panadeine and Concerta. Its instruction is simple: check the ingredients of any medicine you bring into Korea. Penalties under the Narcotics Control Act are severe (KCS cites prison terms and fines running to 100 million won), so this is not a place to guess.

How to get MFDS approval for self-treatment narcotics

If you must bring a controlled medicine for your own treatment, Korean law allows it only with prior approval from the Minister of Food and Drug Safety. MFDS accepts online applications through its Nedrug portal (the "Permit To Bring In Narcotics For Self-treatment" service, available since 2024-12-27). Korean embassy guidance summarising that process states:

For non-controlled prescription medicine, carry it in original packaging with a copy of the prescription or a doctor's letter in English; customs may ask what it is and why you need it. If you run out or get sick in Korea, see /guide/pharmacy-hospital-korea for how pharmacies and hospitals work.

E-cigarettes and e-liquid

Korea Customs allows travellers aged 19 or over a separate tobacco allowance: 200 cigarettes, or e-cigarette liquid nicotine up to 20ml with a nicotine concentration below 1%. Anything above that is taxable, and people under 19 get no alcohol or tobacco exemption at all. MOLIT's 2025 cabin-safety measures covered e-cigarettes alongside power banks, so check your airline's notice on where to keep the device during the flight.

Food, meat and fruit: the quarantine rules

This is where most well-meaning travellers get caught. APQA's guidance for overseas travellers is blunt: do not bring back meat, ham, sausage or other livestock products sold at your destination.

CategoryWhat the official pages say
Meat and processed meatBeef, pork, lamb, chicken; ham, sausage, beef jerky, marinated beef, canned meat — all must be declared to quarantine; products from restricted regions are banned outright, and the restricted list changes with livestock disease outbreaks (KTO / Incheon Airport).
DairyMilk, cheese, butter must be declared (KTO).
Fresh fruit and vegetablesIncheon Airport: "All fresh fruits and fruit-bearing vegetables" cannot be imported. KTO: "almost all fresh fruits and vegetables" are banned.
Plants, seeds, nuts, herbsMust be declared for inspection; seeds and seedlings need a phytosanitary certificate from the exporting country.
Rice, potatoes, walnutsRice plants, husks and straw are banned (polished rice is the exception); unshelled walnuts, unripe beans, unpeeled potatoes and sweet potatoes are banned (KTO).

If you are carrying any of these, tick the animal/plant box on the customs declaration and go to the quarantine counter. Incheon Airport states that fines are imposed for bringing animal products or plants in without quarantine; APQA's traveller page cites administrative fines for failing to declare. Declaring a banned item means it is confiscated; hiding it means a fine. Travellers who visited a livestock farm or market abroad must also declare that on the form.

Cash and the customs declaration

You may bring any amount of money into Korea, but means of payment exceeding US$10,000 in total — foreign currency, Korean won notes or cheques — must be declared on arrival and on departure under the Foreign Exchange Transaction Regulations. KCS lists penalties of up to one year's imprisonment or a fine of up to 100 million won for violations. Non-residents may take out foreign currency they declared on arrival without a new report if the amount is the same.

The general duty-free allowance (US$800 of goods, plus alcohol, tobacco and 100ml of perfume as separate allowances) is covered in /guide/korea-entry-requirements-2026, and how to get won once you land is in /guide/money-and-payments.

Filing the declaration electronically

Incheon Airport says travellers can complete the customs declaration through the "Traveler Customs Declaration" app or website during entry, which is faster than the paper form. Travellers with anything to declare use the "Goods to Declare" lane; everyone else uses the nothing-to-declare lane. If you have a working connection on arrival (see /guide/sim-esim-internet), the web version is the easiest route.

Quick pre-departure checklist

  1. Plug adapter for Type C/F sockets; check every device is rated to 240V.
  2. At most 2 power banks, each under 160Wh, labelled, in your carry-on — and do not plan to use them on the plane.
  3. Read the ingredients of every medicine; apply to MFDS at least 10 business days ahead if any contain a listed narcotic or psychotropic.
  4. Prescriptions or a doctor's letter in English for other medicine.
  5. E-liquid under 20ml and under 1% nicotine; no tobacco allowance under 19.
  6. No meat, sausage, jerky, fresh fruit or vegetables in your bag.
  7. Declare if you carry more than US$10,000 in cash or cheques.
  8. Fill in the customs declaration app or the paper form on arrival.

FAQ

Q. Do I need a voltage converter for Korea?
Only for devices that are not rated for 220V. Korea runs on 220V, 60Hz with round two-pin sockets. Most phone and laptop chargers are marked 100–240V and need just a plug adapter; check hair dryers and other appliances individually.

Q. Can I use my power bank on a flight to Korea?
No. Since 2026-04-20, Korea's Ministry of Land, Infrastructure and Transport prohibits charging a power bank or using one to charge devices in the cabin. You may carry up to 2 power banks of 160Wh or less, in the cabin only; the 2025 guidance also said not in the overhead bin.

Q. Is my cold medicine legal in Korea?
Check the ingredient list. Korea Customs names codeine, dextromethorphan, zolpidem, alprazolam and others as controlled, and cites DayQuil, NyQuil, Robitussin and Sudafed as products caught at customs. If a medicine contains a listed ingredient, you need prior MFDS approval or you should leave it at home.

Q. How do I get permission to bring prescription narcotics or psychotropics into Korea?
Apply online through the MFDS Nedrug portal for a self-treatment narcotics permit at least 10 business days before entry, with your passport copy, flight booking, doctor's certificate and prescription. The permitted amount is your stay's supply plus up to 5 extra days.

Q. Can I bring beef jerky or fruit into Korea?
Meat and processed meat must be declared to quarantine and products from restricted regions are banned; Incheon Airport states that all fresh fruits and fruit-bearing vegetables cannot be imported. Undeclared items attract fines, so declare or leave them behind.

Q. How much cash can I bring into Korea?
Any amount, but means of payment totalling more than US$10,000 — cash in any currency or cheques — must be declared to Korea Customs on arrival and on departure.
