Korea Post and Your Shipping Options
When you've bought more than you can fly home with — too much skincare, a hanbok, a set of ceramics, a load of Jeju citrus — Korea Post (우체국) is the default option, and for most travelers it's the only one you need to think about. Korea Post runs international mail through EMS (Express Mail Service), which it describes as the fastest and most secure way to send parcels and documents abroad, alongside slower registered air parcel and sea parcel options for anything you're not in a hurry to receive.
EMS isn't one flat product. Korea Post distinguishes EMS Standard (regular expedited service, covering roughly 101 countries), EMS Time Certain (a next-business-day guaranteed delivery window of 09:00–17:00, offered only to a handful of nearby destinations such as Hong Kong and Japan), and EMS Premium (an extended-coverage tier beyond standard EMS). For documents mailed from Seoul before noon, Korea Post states delivery to nearby cities like Tokyo, Hong Kong, or Singapore typically takes 2–3 days, with other destinations running 3–5 days; parcels will generally run somewhat longer than that document benchmark, and actual transit time depends on the destination and whether the shipment is pulled for customs inspection there. Booking an EMS shipment online in advance rather than walking up to the counter earns a 5% rate discount according to Korea Post's own site.
I was not able to confirm exact EMS pricing, weight brackets, or the dimensions of the international parcel boxes sold at post office counters from the pages checked for this guide. Korea Post's own fee calculator computes the rate live from destination, actual weight, volumetric (dimensional) weight, and any insurance added, and states that maximum package dimensions differ by destination country — ask at the counter, or use the online calculator, before assuming a price.
Sea parcel is the slow, cheap option for heavy, non-urgent items (boxed ceramics, books) where timing doesn't matter; air parcel sits between plain air-mail documents and full EMS in both speed and cost. I could not verify specific transit times or price tiers for sea versus air parcel, so treat "sea is slow and cheap, EMS is fast and pricier" as the reliable shape of it and confirm current numbers at the counter.
Filling In the Customs Declaration
Every international parcel needs a customs declaration attached, listing the contents and their value. Separately from that, Korea Post's EMS system charges a customs clearance procedure fee when a shipment is selected for inspection or becomes subject to duty at the destination, under Article 32 of the International Postal Regulations; that fee, plus any duty assessed, must be paid before the parcel completes delivery, and once a customs clearance fee is paid it cannot be cancelled — so double-check the tracking number before paying anything against it.
Undervaluing the declared contents to try to dodge duty at the other end is a bad idea for the obvious reason: destination customs authorities compare the declared value against what's actually inside, and a parcel flagged for a mismatch can be held, re-assessed, or penalized rather than simply waved through more cheaply. Declare what's actually in the box, at what you actually paid for it.
Private Couriers: Faster, Pricier
DHL, FedEx, and UPS all operate in Korea and are the faster, pricier alternative to Korea Post for door-to-door tracking and speed. Reasonable for something valuable or time-sensitive; for a suitcase of souvenirs, EMS is usually the more economical route. I did not verify current private-courier pricing for this guide — get a quote directly from whichever courier you're considering.
What You Cannot Ship
Korea Post's EMS prohibited/restricted items list is specific about the categories that trip up travelers most:
- Lithium batteries and power banks: any electronic device containing a lithium-ion or lithium-metal battery — power banks, e-cigarettes, and devices with non-removable batteries included — is prohibited from EMS shipment. Ordinary non-rechargeable AA/AAA batteries are allowed; button-cell batteries are restricted to being built into a single-use product, at most two per item.
- Aerosols: products in metal aerosol containers — hairspray, deodorant, air freshener, insecticide, cleaning sprays — are prohibited. The same product in a plastic or glass container may be permitted.
- Cosmetics: restricted rather than flatly banned — items without a hazard classification marking are generally fine, samples need a Material Safety Data Sheet, and any cosmetic in a metal spray container falls under the same prohibition as other aerosols.
- Food, including kimchi (김치): commercially sold, unopened, sealed products are generally shippable; kimchi specifically is restricted to certain destination countries only, so check before you buy a jar to send. Homemade food or unlabeled samples need food-manufacturing documentation and are much harder to send.
- Alcohol: anything over 60% alcohol content is prohibited outright; lower-proof alcohol must be a commercially packaged, unopened product — no refilled bottles or homemade infusions.
- Agricultural products and seeds: seeds require a quarantine certificate, agricultural chemicals are flatly prohibited, and even organic fertilizer needs organic-material certification paperwork.
This is Korea's export-side restriction list; your destination country layers its own import restrictions on top of it (many countries separately ban incoming meat, dairy, plant material, or soil regardless of what Korea allows out), so check both ends for anything in these categories.
Your Country's Import Duty Is Your Problem
Korea's side of this transaction is the export declaration and the prohibited list above. What happens when the parcel lands in your home country — whether you owe import duty or VAT, and at what value threshold (the de minimis level) that kicks in — is set entirely by your own country's customs agency, not Korea's. That threshold varies enormously: some countries wave through low-value personal parcels duty-free, others assess duty starting close to zero. Look up your own country's de minimis and personal-import rules before you ship, so a bill doesn't surprise you at the door.
Packing and Buying Boxes
International parcel boxes are sold at Korea Post counters in a range of sizes, and staff will help you box and weigh an item on the spot, with packing tape available at the counter. I could not verify exact box dimensions or prices from the sources checked for this guide, so bring your own tape and padding if you're shipping something fragile like ceramics, and ask the counter which box size fits your item rather than guessing.
Shipping and Your VAT Refund
This is the part that catches people out. Korea's Tax Free / VAT refund system for eligible purchases requires customs to confirm, at your point of departure, that the goods are physically leaving the country with you. Korea Customs Service's own guidance describes that confirmation happening at the departure terminal — via a kiosk or an in-person check — before immigration, with your passport, sales certificate, and the unused, unopened goods presented together, and a claim window of three months from purchase. That process assumes you're carrying the goods out yourself. I could not find anything on the official Korea Customs Service pages checked describing an alternative confirmation process for goods shipped or couriered out instead of carried, so assume a shipped item may not be able to complete that refund confirmation. Confirm directly with the retailer and with Korea Customs Service before shipping something you're counting on a VAT refund for.
Bikes and Sports Gear
Shipping a bicycle or bulky sports gear home instead of flying with it and paying an oversized-baggage fee is something EMS and the private couriers can both handle in principle, within the size and weight limits discussed above, but I did not verify a bike-specific service, box, or price. Ask at a post office counter or get a courier quote using the actual boxed dimensions and weight — a disassembled, boxed bike usually needs packaging you'll have to source yourself, since post offices don't stock bike boxes.
Tracking and English-Language Service
EMS shipments to more than 59 countries can be tracked through an integrated system shared between Korea Post and the destination country's postal service; for other destinations, Korea Post says it can provide updates by fax or email instead. Korea Post's international mail site is usable in English for calculating fees and checking delivery estimates by destination.
