Shipping to South Korea from the USA runs on both USPS and UPS with no service suspension in 2026: USPS Priority Mail International (up to 44 pounds to Korea) usually takes 6 to 10 business days, Priority Mail Express International about 3 to 5, and UPS Worldwide Express or Worldwide Saver delivers fastest door to door. The detail that stops most parcels is customs, not the carrier: personal imports generally need the recipient’s Personal Customs Clearance Code (PCCC), and Korea Post asks for the recipient’s mobile number on the customs form.
This guide covers the services on the lane, realistic transit times, Korea’s customs rules, items USPS lists as prohibited, and how to address a parcel so it clears. To price your parcel, compare live USPS and UPS rates to South Korea in the ParcelPath rate calculator.
Before you print a label, double-check the delivery address itself: our Korean address format guide walks through the road-name address order and postal code the local post expects.
Which carriers ship from the US to South Korea?
USPS hands Korea-bound mail to Korea Post, and UPS delivers on its own network with customs brokerage included. USPS’s International Service Alerts page lists no suspension for South Korea. Mail service covers the Republic of Korea only: USPS notes that items addressed north of the 38th parallel are treated as undeliverable.
| Service | Expected delivery | Max weight to South Korea | Best for |
|---|---|---|---|
| UPS Worldwide Express / Worldwide Saver | Typically 1 to 3 business days to major cities | Per UPS package limits | E-commerce orders, B2B and time-sensitive parcels |
| UPS Worldwide Expedited | Typically 2 to 5 business days | Per UPS package limits | Heavier parcels that still need door-to-door tracking |
| USPS Priority Mail Express International | 3 to 5 business days to many major markets | 66 lb; Flat Rate Envelope 4 lb | Urgent documents and small parcels; money-back guarantee available |
| USPS Priority Mail International | 6 to 10 business days | 44 lb; Medium and Large Flat Rate Boxes 20 lb | Gifts and personal parcels |
| USPS First-Class Package International Service | Varies | 4 lb | Light, low-value items |
Unlike many destinations, South Korea accepts merchandise insurance on both Priority Mail Express International and Priority Mail International, and USPS lists the Priority Mail Express International money-back guarantee as available. Restricted Delivery and USPS Delivered Duty Paid are not available to Korea, so the recipient pays any duty and VAT.
Through ParcelPath you can buy USPS labels at up to 89% off retail and UPS labels at up to 85% off, with no subscription, per-label fee or contract. ParcelPath issues USPS and UPS labels only. DHL Express and FedEx also serve South Korea if you book with them directly.
How long does shipping to South Korea take?
USPS states 3 to 5 business days for Priority Mail Express International to many major markets and 6 to 10 business days for Priority Mail International. UPS Worldwide Express and Worldwide Saver generally reach Seoul and other major cities in 1 to 3 business days, and Worldwide Expedited in 2 to 5.
Once a parcel clears customs at Incheon, Korea’s domestic delivery network is fast, with next-day delivery routine in the metro areas. Most delays happen before that point: a missing PCCC, a vague goods description or a supplement that needs food-safety inspection can hold a parcel for days. Peak season from mid-November through early January and the Chuseok and Lunar New Year holidays also slow handling.
What customs rules apply when shipping to South Korea?
The Korea Customs Service (KCS) clears every inbound parcel, and three rules shape most US-to-Korea shipments:
- The Personal Customs Clearance Code (PCCC). Personal imports generally require the recipient’s PCCC, a unique number issued by KCS that replaces the resident registration number on customs paperwork. Recipients get one online from the KCS UNIPASS portal, and carriers ask for it on the invoice. Without it, a personal parcel can sit at customs.
- The duty-free threshold. Low-value personal shipments are generally exempt from duty and VAT. Carriers and KCS guidance put the general limit at US$150, raised to US$200 for goods shipped from the US under the Korea-US Free Trade Agreement (KORUS). Above the limit, duty by product plus 10% VAT applies.
- Accurate origin and value. The KORUS limit depends on the declared US origin, so state the country of manufacture for each item. Commercial shipments also need the six-digit HS code that USPS has required for commercial items since September 1, 2025.
Health functional foods and dietary supplements go through Ministry of Food and Drug Safety screening, and KCS caps how much a person can import for personal use. Multiple small parcels to one recipient arriving together can be combined and assessed as one import, so splitting a large order rarely avoids duty.
What can’t you ship to South Korea?
The USPS International Mail Manual lists these items, among others, as prohibited in mail to South Korea:
- fresh fruits and fresh vegetables, fruit trees, seeds of weeds, and soil or plants with soil attached
- live animals and live insects
- firearms, military swords and loaded cartridges
- salt, pathogens, and machines and paper for making cigarettes
- counterfeit postage stamps and printed matter contrary to public security
Restricted items need US export certificates: agricultural products, herbs and grains (USDA APHIS), dairy (FDA), meat and egg products (USDA FSIS), pet food, and plants or wood packing (phytosanitary certificate). Tobacco and ginseng may be imported only by the Korean government. Coins, currency and jewelry are admitted only by registered First-Class Package International Service, and Priority Mail Express International excludes jewelry and watches entirely.
How do you prepare and address a parcel for South Korea?
- Get the recipient’s PCCC first. Ask for the code before you buy the label and add it to the customs form or commercial invoice.
- Use the full road-name address. Include the building number, road name, district, city or province and the five-digit postal code, and add the address in Korean characters if you have it.
- Add a mobile number and email. Korea Post asks for both on the customs form, and parcels without a mobile number may be delayed.
- Describe items precisely. List each item with quantity, value and country of origin. “Gift” or “clothes” alone invites inspection.
- Check food and supplements. If you’re sending vitamins, snacks or cosmetics, confirm they’re allowed in personal quantities before you ship.
