Shipping from Korea to the US: Korea Post EMS Rates, Duty and Banned Items

Last updated: 19 October 2026 (rates read from Korea Post's live EMS, EMS Premium and international parcel tables, all in force since 1 July 2026; US duty rules from Korea Post's 24 July 2026 notice)

Shipping from Korea to the US got more expensive and more complicated in the last fourteen months, and most English guides still describe the old world. The short version: Korea Post (우체국, ucheguk) will take your box to America, but you now pay the American duty yourself, in Korea, at the counter, before the box leaves. On most parcels the duty is at least 12.5% of what is inside (documents and genuine gifts under $100 are the exceptions). And the souvenirs you bought this week almost never qualify as a duty-free "gift", because Korea Post's own rules say brand-new items in their packaging are not gifts.

This guide gives you Korea Post's October 2026 rates by weight, the US duty rules as Korea Post applies them, what the post office will refuse, how a foreign visitor actually sends a box, and when a second suitcase beats all of it.

Quick Guide: Korea to the US in October 2026

These are Korea Post's published prices to the United States, read from its rate tables on 19 October 2026. EMS prices have been all-in since 1 July 2026; the airmail parcel price below includes the separate ₩6,000-per-kg air surcharge. US duty is extra and is paid at the counter.

Three things jump out. Up to 6 kg, airmail parcel is the cheapest air option — 2 kg costs ₩49,000 against ₩68,500 by EMS. EMS Premium undercuts EMS from 3.5 kg and undercuts airmail from about 6.5 kg — at 10 kg it is ₩74,800 less than EMS. And sea mail costs a fifth of EMS at 10 kg, if you can wait. Korea Post does not publish a fixed transit time for sea mail; plan in months, not days. The sea parcel table jumps from 4 kg to 6 kg, so a 5 kg box pays the 6 kg price.

EMS and EMS Premium charge by the greater of real weight and volumetric weight (length × width × height in cm ÷ 6,000), so a light but bulky box of plush toys can bill as 4 kg. Ask at the counter whether your parcel is measured the same way.

US Duty: What You Pay at a Korean Post Office Now

You pay the US duty in Korea, before the box leaves, and nobody in America gets a bill. Korea Post runs US-bound parcels on a DDP (Delivered Duty Paid, 관세 선납) basis through a payment agent approved by US Customs and Border Protection. That has been the system since Korea Post restored US service in September 2025.

The rate has changed twice since then, and the service has stopped twice. Here is the timeline, from Korea Post's own notices:

The current rules, as Korea Post's 24 July 2026 notice and its earlier customer notices set them out:

• Minimum duty 12.5%. Korea Post's notice puts it as a US Section 301 tariff of 12.5%, with the item's normal US tariff applying instead if that is higher. Its own examples: cosmetics (HTSUS 3304.99) normally 0% → you pay 12.5%; a T-shirt (HTSUS 6109.10) normally 16.5% → you pay 16.5%.
• The sender pays for parcels worth up to $2,500. That limit rose from $800 for parcels arriving from 24 July 2026. Above it, the recipient deals with US customs.
• Gifts up to $100 between individuals stay duty-free, with only a small filing fee ($1.04 in the October 2025 fee table).
• There is a processing fee on top of the duty. When service resumed in October 2025, Korea Post's table for parcels between $100 and $800 was $1.04 plus 10% of the duty, VAT separate.
• You sign a consent form at the counter (미국행 우편물 접수 사전 동의서) accepting that US customs makes the final call, and that a parcel refused for vague or false contents is returned or destroyed without refund of postage or duty.

Why Your Souvenirs Are Not a "Gift"

This is the line that catches travellers. Korea Post's October 2025 notice lists what US customs will not treat as a gift, and the first two describe almost every souvenir haul:

• the contents are new goods — still in the box, in plastic, or with clothing tags attached
• the sender's name is a company, or the box carries a company logo
• one person sends the same item to several people
• free samples or bonus items that came with a purchase

So a box of Olive Young sheet masks for your sister, still sealed, is dutiable even though you are not selling anything. Declare it honestly; Korea Post warns that undervaluing (writing $90 on a $130 box) gets parcels returned or destroyed.

A Worked Example

You send 2 kg of Korean skincare worth $150 to a friend in the US by EMS:

The same 2 kg in a checked bag costs nothing extra if you are under your airline allowance. That is the comparison to make before you queue.

Korea Post Prices to the UK, Canada, Australia and Japan

If your box is going somewhere other than the US, the duty section above does not apply; your destination's own import rules do. EMS prices from Korea Post's 1 July 2026 non-document table:

Note how much the US costs by comparison: 10 kg to the US by EMS is ₩233,500, against ₩163,000 to the UK. Airmail parcels to the UK and Canada carry a ₩6,100-per-kg air surcharge on top of the parcel table, and to Australia ₩2,100 per kg.

What Changed on 1 July 2026

Before July, EMS had a published rate plus a separate fuel-style surcharge (추가운송수수료). On 1 July 2026 Korea Post folded the surcharge into the EMS non-document price and set the surcharge to zero for every country, so the EMS table is now the final price. Korean press put the published 0.5 kg EMS rate to the US at about ₩29,500 before the change; the all-in price is now ₩39,000, so part of that jump is the surcharge moving into the table. Airmail parcels and small packets still carry the separate surcharge — ₩6,000 per kg to the US since 11 December 2025 — and sea parcels to the US carry ₩100 per kg.

What Korea Post Will Not Take

Korea Post's "what you can and cannot send" page (보낼 수 있는 물품/보낼 수 없는 물품) is more specific than most English guides suggest. The items travellers most often try to post:

Extra Rules for the US

Since 24 July 2026 Korea Post refuses US-bound mail containing goods under US quota, anti-dumping or countervailing duties. The quota list on its 29 July notice reads like a Korean snack haul: sugar, tuna (including canned), citrus, peanut butter, peanuts, beef, infant formula, chocolate, cheese, milk and milk powder, condensed milk, ice cream, other dairy, and animal feed. A box of chocolate Pepero or a jar of powdered milk is not going by post. EMS Premium can take some of these goods, but not food.

Two older US-only rules still stand in Korea Post's notices: documents only for US letter mail (photocards, calendars and booklets posted as "documents" were sent back by US customs), and no cosmetics on US-bound EMS Premium, which UPS stopped accepting in October 2025 after stricter FDA checks. EMS Premium moved to FedEx on 1 April 2026 and Korea Post has not published a new cosmetics rule since, so ask at the counter, or simply send cosmetics by EMS or parcel.

If you are thinking about food, sealed shop-bought kimchi is a famous exception Korea Post has advertised for the US, but US food imports still need a prior notice to the FDA (Korea Post's EMS site has a 미국행식품사전신고 page for it). For snacks, read our Korean grocery store shopping guide before you buy in bulk.

How to Send a Box from a Korean Post Office as a Foreigner

You do not need a Korean phone number, residence card or bank account. You need the box, the address, and ten minutes of honest paperwork.

1. Pre-register online for 5% off. Korea Post's international smart registration (국제우편 스마트접수, at ems.epost.go.kr or the 우체국 app) lets you type the addresses and the customs declaration in English in advance. Its rate page says pre-registered EMS gets 5% off (not if you pay with stamps). At the counter, staff print the label from your registration.

2. Pick a branch and go before 17:30. Most branches run the postal counter 09:00–18:00 on weekdays. The Jangan-dong branch above posts a 09:00–17:30 cut-off for same-day dispatch. Branches are closed on weekends and public holidays, so do not plan this for your last Saturday.

3. Pack, or buy a box there. Branches sell Korea Post boxes in numbered sizes and tape. Bring your own bubble wrap.

4. Fill in the customs declaration line by line. CN22 for small items, CN23 for larger ones; on EMS it is part of the label. Write the contents the way Korea Post's own example does: not "clothes" but "men's cotton crew neck T-shirt", with quantity, value in US dollars, the HS code if you have it, and country of origin: South Korea. Korea Post warns that a missing origin can mean US customs applies another country's rate.

5. Sign the US consent form (for US-bound parcels only), in person.

6. Pay postage and duty together. For US parcels Korea Post takes cash, bank transfer, or a physical credit card since December 2025. Mobile wallets such as Samsung Pay are not accepted for postage or duty, and on a card the duty must be paid in the same transaction as the postage.

7. Photograph the receipt. The tracking number on it works on Korea Post's English tracking page and, for EMS, on USPS once it lands.

If you run out of time in the city, Incheon Airport Terminal 1 has its own Korea Post branch. Check its hours before relying on it, and arrive with time to spare before check-in.

Private Couriers and Forwarding Services

EMS Premium already is the private courier. Since 1 April 2026 Korea Post has carried EMS Premium through FedEx (it was UPS before, and Korea Post's English page still says UPS), up to 70 kg, so it is the cleanest way to price a courier without leaving the post office. From 3.5 kg it undercuts regular EMS to the US, and the sender-pays-duty option that used to cost ₩25,000 has been free since the switch.

DHL, FedEx and UPS Korea all take walk-in or pickup shipments, but they quote by account and by zone rather than through a single public table, so get a quote on their Korean sites with your real box size. Two things to check that the post office handles for you: who pays US duty (couriers usually bill the recipient, with brokerage fees; Korea Post's October 2025 notice listed a UPS brokerage charge of $14 or 2% of duty, whichever is higher), and whether the courier collects duty up front.

Forwarding and shopping-agent services make sense when you are buying online in Korea from abroad, not for a box you already hold. If you are already in Korea with the goods, the post office is simpler.

Tax Refund and Shipping

If you plan to claim a tourist VAT refund at the airport on the same goods, settle that before you ship. The refund system assumes the goods leave Korea with you, and once they are sealed in a box at a post office there is nothing to show at the airport. Instant refunds taken at the shop have their own rules; our Korea tax refund guide has the limits.

How to Pack Souvenirs for Korea Post

Pack as if the box will be stacked under heavier boxes and shaken for a week.

• Books, albums, stationery: heavy and tough. Protect corners and fill gaps so nothing slides.
• Clothes: compress, bag against moisture, remove extra packaging before weighing — but declare them as new if they are new.
• Cosmetics: seal caps, bag liquids separately, skip sprays and anything with a flammable mark.
• Ceramics and glass: real padding, or carry them. A shop bag is worthless once the box leaves your hands.

Do the gentle-shake test. If things move, add padding. If the box bulges, repack. Two moderate boxes are safer than one overloaded one, and the price table is roughly linear above 5 kg anyway.

Ship, Buy a Bag, or Carry Less?

The honest answer for most travellers is the bag. 10 kg to the US costs ₩233,500 by EMS plus duty; an extra checked bag often costs less (check your airline's fee), carries no US postal duty, and arrives when you do.

For multi-city trips, ship from Seoul before you leave for Busan or Jeju rather than on the morning of a train; see our KTX, SRT and express bus guide. If you are still shopping, our Korea coin laundry guide shows how to travel with fewer clothes, which leaves suitcase room for what you buy.

FAQ

Q: Is Korea Post EMS to the US running right now?

Yes. US-bound EMS, airmail and sea parcels and K-Packet have been accepted since 22 October 2025, on the prepaid-duty basis. Service stopped in late August 2025 when the US ended the $800 exemption and again after the data-centre fire in late September 2025, which is why some pages still say it is suspended. Check the notices on ems.epost.go.kr before you go, because it has changed more than once.

Q: How much does EMS from Korea to the US cost?

₩39,000 for 0.5 kg, ₩46,000 for 1 kg, ₩68,500 for 2 kg, ₩128,500 for 5 kg and ₩233,500 for 10 kg, from Korea Post's table in force since 1 July 2026. On dutiable contents, US duty of at least 12.5% of their value, plus a small fee, is added at the counter.

Q: What is the cheapest way to ship from Korea to the USA?

Sea parcel (선편소포): about ₩44,000 for 10 kg against ₩233,500 by EMS, but it takes weeks to months. For air, airmail parcel (항공소포) is cheapest up to about 6 kg, and EMS Premium from about 6.5 kg up.

Q: Do I pay duty on a gift to the US?

Only if it is not a "gift" in US customs' sense. Gifts up to $100 between individuals are duty-free, but Korea Post's notice says new items in packaging or with tags, items with a company logo, and the same item sent to several people do not count.

Q: Can I ship a phone or a power bank from Korea?

No. Korea Post refuses lithium batteries and any device containing one, of any capacity. If the battery can be removed, you may send the device without it.

Q: What customs form do I need?

CN22 for small items or CN23 for larger ones; with EMS it is built into the label. List each item specifically, its quantity, its value in US dollars, and country of origin. Pre-registering online fills it in for you and gives 5% off EMS.

Q: Can I ship Korean snacks to the US?

Some. Since 24 July 2026 Korea Post refuses US-bound goods on the quota list, including chocolate, sugar, peanuts, peanut butter, cheese, milk powder and other dairy. Check the ingredients before you pack, and remember US food imports need an FDA prior notice.

Bottom Line

Korea Post still gets your box to America, but the maths has changed. On most parcels you pay the duty, at least 12.5%, at the counter; your souvenirs are not gifts; and EMS to the US costs more than to the UK. Weigh first, ship heavy and durable things by sea or EMS Premium, small ones by airmail parcel, keep batteries and perfume in your luggage plan, and buy a second bag when the box would weigh more than about 5 kg.
