Declare when the exact item, quantity, value, purpose, or rule is uncertain. Korea customs is not only about expensive shopping. Food, medicine, cash, gifts, commercial samples, animals or plants, and goods sent separately can require a declaration or another authority’s review even when their price is low.
This guide separates the decisions. It does not grant entry permission, medicine approval, quarantine clearance, duty exemption, or release of a shipment. Use the current official form or ask an officer before leaving the controlled arrival area.
Use the authority responsible for each question
| Question | First authority | What this decision does not settle |
|---|---|---|
| May I enter Korea? | Immigration and the entry system | Customs, quarantine, or duty |
| Must I declare this good or value? | Korea Customs Service passenger guide | Food, plant, animal, or medicine permit |
| Is this controlled medicine approved? | MFDS controlled-medicine permit guidance | Airline acceptance or a customs decision on other goods |
| Can it travel in my cabin or checked bag? | Departure airport security and the operating airline | Whether Korea admits or taxes it |
An e-Arrival card, immigration permission, customs declaration, quarantine inspection, and airline check are separate. Completing one is not evidence that the others are complete.
Make one honest inventory before opening any form
- Passport, flight, arrival date, and Korean address.
- Every purchase, gift, sample, repair item, and item carried for someone else.
- Food, meat or animal product, fruit, vegetable, seed, plant, medicine, supplement, alcohol, tobacco, and perfume.
- Cash, KRW notes, checks, and other covered means of payment in all currencies.
- Receipt or reasonable value evidence, quantity, condition, ingredients, and purpose.
Descriptions such as ‘snacks,’ ‘medicine,’ or ‘personal items’ may be too vague. Keep the original label and describe the actual product, quantity, value, and use. Never split a purchase between travelers or change the description to create an artificial allowance.
Know the current passenger duty-free figures—but do not stop there
Korea Customs Service currently lists a basic passenger allowance of US$800 or less of total taxable value. It separately lists liquor up to 2 liters in total and US$400, 200 cigarettes, qualifying e-cigarette liquid up to 20 ml, and perfume up to 100 ml. The page says people under 19, based on year of birth, do not receive the liquor and cigarette allowance.
| Category | Current KCS figure | Important limit |
|---|---|---|
| General goods | US$800 or less total taxable value | This is not permission for restricted goods |
| Agricultural, livestock, fishery goods | Within the KCS passenger conditions | The page lists 5 kg per item, 40 kg total, and KRW 100,000 total overseas purchase value |
| Liquor | Up to 2 L total and US$400 | Separate allowance; no allowance under 19 |
| Cigarettes | 200 sticks | Separate allowance; no allowance under 19 |
| Perfume | 100 ml | Separate from the basic allowance |
A duty-free threshold is not a safe-item list. KCS states that restricted goods must meet their clearance requirements regardless of the tax-exemption threshold. Food, medicine, animal or plant products, and commercial goods may require review even below US$800.
Declare goods over an allowance and goods in controlled categories
KCS lists goods over allowances, commercial goods, samples, repair goods, certain weapons or toxic materials, medicines that may be misused or abused, animals and plants and their products, agricultural and food products, CITES-related items, counterfeit goods, and other specified categories as goods to be declared.
The passenger guide states that a voluntary declaration for goods over the allowance receives a 30% reduction from the standard customs duty. It also warns of additional tax for non-declaration: 40%, or 60% if exposed at least twice within two years. Do not use those percentages as a tax quote for an exact item; ask Customs for the calculation.
Food needs both customs and quarantine thinking
KCS includes animals, meat, skin or hair, plants, fruit, vegetables, live fish, agricultural, forestry, livestock and fishery products, processed goods, and other foods in its declarable list. A sealed package or a low price does not prove admission. Keep the ingredient label and country of origin visible and declare rather than guessing.
Do not discard, hide, or consume an uncertain item to avoid a question. Ask Customs or quarantine staff while you are still in the controlled area. The officer may refer the product to the responsible inspection authority.
Medicine: product name is not enough
Record the active ingredient, strength, dosage form, quantity, prescriber, and intended treatment. Keep the medicine in its labeled packaging with supporting prescription or medical documentation when available.
MFDS guidance says anyone entering Korea with medicine containing controlled substances must obtain an MFDS permit regardless of nationality. The page notes that online applications have been available since December 27, 2024. Do not assume legality in another country, a prescription, or a small amount replaces the Korean approval route.
Cash and checks are aggregated across covered means of payment
KCS foreign-currency guidance states that arrival with foreign currency, KRW notes, or covered checks above US$10,000 or the equivalent in total must be reported to Customs. It instructs the traveler to mark the relevant declaration item, state the amount, submit it, and receive a certificate.
This is a declaration threshold, not a prohibition on carrying money. Currency conversion, ownership, and the type of payment instrument can matter, so ask Customs when the total is close or the instrument is unusual.
Choose the current declaration channel
- Review the official traveler declaration form before the trip.
- Use the current KCS mobile traveler-declaration service only if it fits your arrival and the service is available.
- If the form or service does not fit your facts, use the declaration route and ask an officer.
- Keep labels, receipts, prescriptions, values, and quantities accessible until clearance is complete.
A green lane, automated gate, or lack of a question is not a personal legal opinion. When a fact is unclear, a declaration creates a path for the responsible authority to decide it.
Goods sent separately use an additional route
A delayed airline bag, cargo shipment, courier parcel, and household move do not share one procedure. Keep the transport document and use the separate unaccompanied luggage guide. Declare the goods honestly on arrival when the traveler process asks about separate shipments, then follow the carrier or broker’s written clearance instructions.
What to do when the answer is still unclear
- Do not conceal the item or invent a category.
- Keep the exact item, packaging, receipt, and documents available.
- Use the official declaration lane or channel before leaving the controlled area.
- Ask which authority owns the unresolved question and obtain the next step.
- Keep any declaration certificate, receipt, or written instruction.
Frequently asked questions
Is every item below US$800 duty-free and allowed?
No. The figure is a tax allowance, while restricted, declarable, quarantine, medicine, and commercial-goods rules are separate.
Do I declare prescription medicine?
Check its active ingredient and Korean classification. Controlled-substance medicine requires an MFDS permit regardless of nationality; use the official route when classification is unclear.
What if I carry more than US$10,000?
KCS describes a declaration process for covered currency, KRW notes, and checks above the equivalent threshold. Report the total and keep the certificate.
