Quick summary
South Korea’s customs declaration QR code is a goods-only tool, not an entry document. It applies when taxable imports exceed the US$800 duty-free allowance, or when alcohol, cigarettes, perfume or cash cross their own limits. File through the Korea Customs Declaration for Travelers app before landing and the code is scanned at the Goods to Declare gate.
Declaring voluntarily cuts duty by 30%, capped at ₩200,000; undeclared goods caught in the green channel trigger a 40–60% surcharge. The customs QR is not immigration paperwork, and the arrival card is a separate system.
On 13 October 2026, the Korea Customs Service released mobile-first traveler baggage processing for Incheon International Airport, adding app-based declaration and in-app duty payment to a system that had already gone nationwide. For anyone landing with over-limit purchases, the declaration, tax calculation and payment can now all happen on a phone before the aircraft doors open.
For travelers from North America, Europe including the UK, and Australia and New Zealand, the key figure is US$800 in total taxable value per arriving passenger. That is Korea’s duty-free allowance. But it does not cover everything in the suitcase. Alcohol, cigarettes, perfume and cash have separate limits, and crossing any of them also makes a declaration necessary.
What matters is not just what you carry, but whether you declare it.
What the US$800 allowance actually covers
The allowance applies to the combined taxable value of what each arriving passenger carries. Alcohol, cigarettes, perfume and monetary instruments have independent limits. A traveler below the value threshold can still have something to declare: a carton of cigarettes or a stack of cash above its reporting line.
The published limits, as of October 2026, allow alcohol up to 2 liters with a value up to US$400. The cigarette limit is 200. For perfume, it is 100 milliliters. Travelers under 19 have no alcohol or tobacco allowance at all.
Cash and monetary instruments must be declared when the total exceeds US$10,000 per person. Meat is generally banned, with narrow exceptions for store-bought, shelf-stable products up to 5 kilograms that are declared.
Duty applies only to the amount over the limit, not the whole purchase. A US$1,000 laptop does not mean duty on US$1,000.
The flat 20% simplified customs rate was abolished on 28 February 2023, so per-category rates now apply. Most goods are taxed at 15%. Leather and textiles carry an 18% rate, fur 19%, and deer antler 21%.
Superdeals cover departures from North America, Europe and Australia.

When you need the customs QR code
Since 1 May 2023, travelers with nothing to declare use the Nothing to Declare lane and skip the paper form entirely. Those with goods to declare can file on paper or through the Korea Customs Declaration for Travelers app, which produces a QR code.
The app route has been available since 29 August 2022. The mobile system expanded to airports and seaports nationwide on 1 May 2023, so it is not limited to Incheon. The app works anywhere with internet access, including on board if your aircraft has connectivity.
One declaration can cover a family traveling together. A family of four flying home with US$3,000 in combined purchases sits under the US$3,200 covered by their four per-person allowances, yet the group files only once.
A unified QR covering both customs and immigration has been discussed.
The 30% carrot and the 40–60% stick
Declaring voluntarily reduces the bill. Under Article 96(2) of Korea’s Customs Act, it cuts the duty owed by 30%, capped at ₩200,000 off, according to Korea Customs Service guidance current as of October 2026.
Undeclared goods caught in the green channel attract a penalty of 40% of the tax due. That rises to 60% for a second offence within two years.
The livestock penalties are steeper. Undeclared livestock products carry fines of ₩1,000,000 for a first offence, ₩3,000,000 for a second and ₩5,000,000 for a third, according to Korea Customs Service guidance current as of October 2026.
Undeclared pork from African swine fever countries is treated more harshly still: ₩5 million for a first offence, ₩7.5 million for a second and ₩10 million for a third. Plant products carry a separate cap of ₩3,000,000.
For a single purchase, the gap is clear. A US$1,200 handbag declared voluntarily, with duty at the 18% leather rate, comes to US$216. The voluntary reduction brings that to about US$151.
The same bag found undeclared in the green channel attracts a surcharge on the tax due, pushing the bill to roughly US$302. Declaring saves about US$151 on one purchase, and the gap widens with the value of the goods.
Customs QR is not immigration
Three separate systems get confused with customs. The customs QR covers goods. The e-Arrival Card covers immigration paperwork, while K-ETA is a separate travel authorization. Q-Code is a health declaration that has been optional since COVID-19 entry restrictions were lifted on 15 July 2023.
The e-Arrival Card is free at e-arrivalcard.go.kr. It can be submitted starting three days before arrival and is valid for 72 hours from submission. A verification-code step was added in May 2026.
Each traveler, including children and infants, submits an individual card. A 2025 notice suggested ending paper arrival cards after December 2025, but as of October 2026 both paper and electronic options were still available.
K-ETA costs KRW 10,000 and is valid for up to three years. Processing typically takes 24 to 72 hours. Temporary exemptions for many nationalities, including the United States, Canada, the United Kingdom, Australia and New Zealand, run until 31 December 2026, after which the requirement returns for those passport holders.
Third-party services charging KRW 30,000 to 80,000 for the same application are discouraged. The official portal is the only one that matters.
At the airport: gate, app, and mobile duty payment
At Incheon, the physical process is short. The QR code is scanned at the Goods to Declare gate past baggage claim. Everyone else, personal effects and all, exits through the standard doors.
The official mobile app can calculate estimated import tax for items exceeding the duty-free allowance and take payment directly in-app, covering VAT and other assessed taxes. The web portal handles quick filing but not duty payment, so settling the bill before reaching an officer requires the app rather than the browser.
The estimate is not the final bill. High-value items or inaccuracies in a mobile declaration can lead to penalties or additional surcharges. Spot checks verify the filing against physical luggage, and the final payable amount is confirmed after on-site inspection. The exchange rate is the one in force on the declaration date.
One part of the 2026 picture remains unconfirmed. A Korean press report from that year, carrying no source attribution, describes some foreign arrivals at Incheon still facing three parallel inbound requirements: a health questionnaire, an arrival card, and the goods declaration. Treat it as unverified.
Before the aircraft doors open
The filing window closes the moment you walk up to the Goods to Declare gate.
- Total before you pack the taxable value of everything you are bringing in, per person, and check alcohol, cigarettes, perfume and cash against their separate limits.
- File on the official channel — the Korea Customs Declaration for Travelers app or the Korea Customs Service website — before landing so the QR exists at the gate.
- Keep the QR on your phone rather than printed; it is scanned at the gate, and the app is also where in-app duty payment happens.
- Watch: whether the arrival card and customs declaration merge into one QR, and whether the K-ETA exemption for US, UK, Australian and New Zealand passport holders is extended past 31 December 2026.
That two-minute task is the difference between a gate scan and an assessment. For a family filing together, total the whole group’s purchases before deciding.

Questions? Answers.
What to declare at customs in Korea?
Anything whose taxable value pushes you over the US$800 per-person allowance, plus alcohol over 2 liters or US$400, cigarettes over 200, perfume over 100 milliliters, and cash or monetary instruments over US$10,000. Meat is generally banned, with narrow exceptions for declared, shelf-stable products up to 5 kilograms.
Do I need a QR code to enter South Korea?
Only if you are declaring goods. The customs QR is generated when you file a goods declaration online and is scanned at the Goods to Declare gate. It plays no role in immigration and is not the arrival card, so a traveler with nothing to declare enters without one.
When should I fill out the customs declaration?
Before you reach the Goods to Declare gate, which makes the flight itself the practical window. The QR has to exist on your phone when you arrive, and the app works anywhere with internet access, including on board if your aircraft has connectivity.
Do I have to print the customs declaration?
No. Filing online produces a QR code scanned on arrival instead of a paper form, and the app is also where in-app duty payment happens. The web portal handles filing but not payment, so the app is the more complete option.
How much is the duty reduction for declaring voluntarily?
Thirty percent off the duty owed, capped at ₩200,000, under Article 96(2) of Korea’s Customs Act. Undeclared goods caught in the green channel instead attract a 40% surcharge on the tax due, rising to 60% for a second offence within two years.
Does one declaration cover a family?
Yes. One declaration form can cover a family traveling together, which matters because the US$800 allowance is measured per arriving passenger. Total the whole group’s purchases before deciding whether to file, and match the submission to what is physically in the bags, since spot checks verify against luggage.
