How to Import From South Korea to USA in 2026: Complete Guide

Updated June 27, 2026 — by the TariffWise editorial team · 13 min read

South Korea is the sixth-largest US trading partner, sending about $130 billion in goods to American buyers each year. Semiconductors, EV batteries, automobiles, K-beauty, and home appliances dominate the trade. For 2026, the rules are a moving target: the long-standing KORUS Free Trade Agreement still zeroes out most base MFN duties, but the Trump reciprocal baseline tariff announced in April 2025 stacks on top — and Section 232 actions on semis, steel and autos add more layers. This guide walks you through everything you need to file a Korean import correctly and pay the lowest legal duty.

Why Korea matters in 2026

Korea is the only Asian country in the US top 10 trading partners that combines three rare features: an active US free-trade agreement (KORUS), a tech-heavy export mix that's hard to source elsewhere, and a politically aligned government that has avoided the worst of Trump's tariff escalations. Vietnam, Mexico and India have caught some of the China overflow, but Korea retains structural advantages for specific product categories.

The trade flow in 2025-2026:

• Semiconductors: Samsung and SK hynix supply roughly 60% of global DRAM and 40% of NAND. There is no substitute at scale.
• EV batteries: LG Energy Solution, Samsung SDI and SK On together command ~25% of the global EV battery market and dominate US assembly partnerships.
• Vehicles: Hyundai and Kia ship ~700,000 vehicles to the US annually. Most go through KORUS preferential treatment, partially offsetting reciprocal duty.
• K-beauty: $1.5+ billion in cosmetics exports to the US, growing 25-30% year over year. Independent buyers and importers can win in this space.
• Appliances: LG and Samsung dominate US refrigerator, washer and dryer imports.

KORUS FTA — what it actually does for your bill

The US-Korea Free Trade Agreement entered into force in March 2012 and was renegotiated in 2018 under Trump's first term. KORUS eliminates the base Most-Favored-Nation (MFN) duty on roughly 95% of tariff lines between the two countries.

What KORUS still does in 2026:

• Eliminates base MFN duty on qualifying goods (most consumer and industrial products).
• Provides specific rules of origin so goods must be sufficiently Korean to qualify.
• Allows duty drawback and tariff preference programs not available to non-FTA partners.

What KORUS does NOT do in 2026:

• It does not exempt Korea from the Trump reciprocal baseline tariff (15% as of mid-2026). Reciprocal duties were imposed unilaterally under IEEPA and override FTA preferences for that tariff line.
• It does not exempt Korea from Section 232 actions on steel, aluminum and (phased-in) semiconductors. Korean steel has historically had a quota arrangement instead of the full 232 tariff, but the situation is being renegotiated.
• It does not exempt Korean autos from the Section 232 auto tariff. KORUS provides a partial offset but does not zero out the duty.

Bottom line: KORUS still saves you the base MFN duty (often 2-25 percentage points depending on the product), but the headline "duty-free" of 2014 is long gone.

Current US tariffs on Korean goods (mid-2026)

Tariff rates change frequently. The table below reflects the situation as of mid-2026 — always cross-check with the latest CBP CSMS messages and the Federal Register before filing.

For a typical non-sectoral Korean import in 2026, expect a landed duty of about 15-16% (reciprocal + MPF + HMF). For autos, semis or steel, the actual rate can be materially higher and product-specific.

Top product categories US importers buy from Korea

These are the categories where Korean suppliers consistently win on quality, cost or both:

1. Semiconductors and memory chips — Samsung and SK hynix DRAM/NAND for the data center, mobile and automotive supply chains.
2. EV batteries and battery components — LG, Samsung SDI, SK On cells and packs for US auto assembly.
3. K-beauty and skincare — sheet masks, serums, sunscreens, cushion compacts. Margins are strong and barrier to entry is moderate.
4. Home appliances — refrigerators, washers, dryers (LG, Samsung). Many now assembled in US plants but components and high-end SKUs still imported.
5. Vehicles and auto parts — Hyundai, Kia, Genesis vehicles; tier-1 supplier parts.
6. Steel and steel products — within the quota system, Korean steel is competitive on quality.
7. Consumer electronics — TVs, monitors, audio equipment.
8. Industrial equipment — robotics, machine tools, power equipment.
9. Petrochemicals and plastics — engineered plastics, specialty chemicals.
10. Processed food — instant noodles, kimchi, snacks, alcoholic beverages (soju).

Finding and verifying Korean suppliers

Korean B2B sourcing has matured significantly. Unlike China, the main risk in Korea is not counterfeiting or quality fraud but capacity allocation — top suppliers heavily prioritize their largest customers.

Where to start

• KOTRA (Korea Trade-Investment Promotion Agency) — government-run, free supplier matching service. kotra.or.kr
• EC21, GoBizKOREA, TradeKorea — Korean equivalents of Alibaba, more curated.
• Direct outreach to chaebol divisions — Samsung, LG, Hyundai have global B2B portals.
• Korea trade shows — K-BEAUTY EXPO (cosmetics), KIMES (medical devices), KES (electronics).

Verification checklist

1. Request a copy of the supplier's Business Registration Certificate (사업자등록증) issued by the Korean National Tax Service. Verify it through KOTRA's free service.
2. Confirm export license for your product category (some require MOTIE certification).
3. Request KOLAS test certificates for any product subject to US FDA, FCC or CPSC oversight.
4. For KORUS preference: get written confirmation the supplier will issue a KORUS Certification of Origin. Without it you cannot claim preferential treatment.
5. Visit in person for orders above $50,000 — flight to Seoul is shorter than to most Chinese supplier cities and Korean factories are far more transparent.

Shipping and logistics

Main routes

Busan handles roughly 75% of Korean container exports. Incheon is the main air freight gateway and is essential for high-value, time-sensitive shipments such as semiconductors and pharmaceuticals.

Incoterm recommendations

For most Korean imports, FOB Busan is the cleanest term. You take title once goods are loaded and control your freight forwarder of choice. CIF can work for smaller importers but adds cost and removes your ability to negotiate ocean rates. DDP sounds attractive but became risky after Trump tariff changes — most Korean exporters refuse to absorb the reciprocal duty fluctuation.

See our full guides on FOB vs CIF and DDP vs DAP for the trade-offs.

Customs clearance specifics for Korean imports

The CBP entry process for Korean goods is mechanically the same as any other origin, but a few specifics matter:

• HTS classification — same Harmonized Tariff Schedule as all imports. Use hts.usitc.gov and our HTS code guide if unsure.
• Country of origin marking — "Made in South Korea" or "Made in Korea" on the product itself (not just packaging) for most consumer goods.
• KORUS Special Program Indicator — file with code KR on the CBP Form 7501. Without it, you pay full reciprocal tariff and lose the base MFN saving.
• FDA prior notice for cosmetics, food, drugs, medical devices.
• FCC declaration for any electronic device that emits radio frequency.
• ISF (Importer Security Filing) required 24 hours before lading at Busan. See our ISF guide.

Real cost example — Korean cosmetics shipment

Let's price out a realistic K-beauty import: a 20-foot container of sheet masks and serums, FOB Busan value $35,000.

Of that 27.6% markup, roughly 16.2 percentage points are duty & fees (15% reciprocal plus MPF, HMF and broker). Without KORUS you would also be paying the base MFN duty of ~3.8% on top — KORUS still saves you about $1,440 on this shipment.

7 common mistakes importers make with Korean shipments

1. Forgetting the KORUS Certification of Origin. Without it, you pay full reciprocal + base MFN. The certification is free but the supplier has to issue it.
2. Filing entry without the KR Special Program Indicator. Even with the certificate in hand, you must claim it on Form 7501.
3. Assuming KORUS still means 0% total duty. Reciprocal stacks on top. Most goods land at ~15%, not free.
4. Wrong HTS classification. Cosmetics, electronics and dietary supplements have multiple plausible codes with materially different duty.
5. Missing FDA prior notice for cosmetics/food/supplements. Results in CBP hold and storage charges.
6. Choosing DDP with Korean exporters. Many refuse to absorb the reciprocal duty risk; the deal can collapse mid-shipment.
7. Ignoring the section-specific tariffs. Steel, aluminum, autos, semiconductors all have their own additive layers beyond the reciprocal baseline.

How to claim KORUS preferential tariff treatment

Three things must be in place at the time of entry:

1. The good qualifies under KORUS rules of origin. Either wholly obtained in Korea, made entirely from KORUS materials, or transformed enough under the product-specific rules in the agreement annex.
2. You have a KORUS Certification of Origin on file. No fixed format — can be a formal certificate or a declaration on a commercial invoice. Must include nine data elements: importer, exporter, producer, HTS classification, description, origin criterion, period (if blanket), signature and date.
3. You file the entry with Special Program Indicator KR. On Form 7501 in column 27, the country of origin appears as "KR" and the duty rate code references the preferential rate.

CBP can ask to see the certificate for up to 5 years after the entry date. Store it with your records. If CBP audits and you cannot produce it, the preferential treatment is denied retroactively and you owe back duty plus interest.
