How to Import from South Korea to USA: Complete Guide (2026)

## Why Import from South Korea? South Korea is a manufacturing powerhouse that punches far above its weight. With a $1.7 trillion GDP and world-class industries in electronics, automotive, chemicals, cosmetics, and machinery, Korea offers US importers a combination of high quality, competitive pricing, and preferential trade access that few countries can match. ### Key Advantages | Factor | Details | |--------|---------| | KORUS FTA | 95%+ of goods enter duty-free or at reduced rates | | Quality standards | Korean manufacturing rivals Japan/Germany in precision | | Logistics | Busan is world's 7th-busiest port; excellent infrastructure | | IP protection | Strong intellectual property enforcement | | English proficiency | High among business professionals | | Payment reliability | Low commercial risk; strong banking system | | Section 232 quota | Negotiated exemption for steel within limits | ### Top Korean Exports to the US 1. **Vehicles and auto parts** — Hyundai, Kia, and tier-1/tier-2 suppliers 2. **Semiconductors and electronics** — Samsung, SK Hynix, LG 3. **Machinery and equipment** — Industrial robots, machine tools 4. **Petrochemicals and plastics** — Large chemical industry 5. **Cosmetics and skincare** — K-beauty boom continues 6. **Steel and metals** — POSCO, Hyundai Steel 7. **Lithium-ion batteries** — LG Energy Solution, Samsung SDI, SK On 8. **Ships and marine equipment** — World-leading shipbuilders ## KORUS Free Trade Agreement: Your Duty-Saving Tool ### What KORUS Covers The agreement eliminated tariffs on the vast majority of goods traded between the US and Korea. As of 2026, the phase-out schedule is nearly complete: | Category | % Now Duty-Free | Remaining Tariffs | |----------|----------------|-------------------| | Industrial goods | 98%+ | Few remaining items fully phasing out by 2026 | | Consumer goods | 95%+ | Some textiles have longer phase-outs | | Agricultural goods | 85%+ | Some sensitive items (beef, pork) still phasing down | | Automotive | 100% | All tariffs eliminated as of 2021 | ### How to Claim KORUS Preferences **Step 1: Verify your product qualifies** Check two things: - Is your HS code eligible for KORUS preferential rates? (Check the KORUS tariff schedule) - Does your product meet the Rules of Origin? (See below) **Step 2: Obtain or create a Certificate of Origin** KORUS uses self-certification — no government stamp needed. The exporter, producer, or importer can certify origin. The certification must include: - Name and address of the certifier - Exporter's name and address (if different) - Producer's name and address (if different) - Product description and HS tariff classification - Origin criterion met (A through D — see below) - Blanket period (if covering multiple shipments, up to 12 months) - Signature and date **Step 3: Claim preference at entry** Your customs broker marks the entry as claiming KORUS preferential treatment. The certificate isn't submitted with the entry but must be available if CBP requests it (keep for 5 years). **Step 4: Maintain records** Both importer and exporter must keep supporting documentation for 5 years. CBP can verify origin claims at any time. ### Rules of Origin — The Critical Requirement Not everything shipped FROM Korea qualifies for KORUS rates. The product must ORIGINATE in Korea under specific rules: **Origin Criteria:** | Criterion | Meaning | Example | |-----------|---------|---------| | A | Wholly obtained/produced in Korea | Korean-grown agricultural products, Korean-mined minerals | | B | Produced entirely in Korea from originating materials | Korean-made steel from Korean iron ore | | C | Meets product-specific rule (tariff shift and/or RVC) | Most manufactured goods — uses components from various countries but meets transformation rules | | D | Produced in Korea exclusively from originating materials of Korea and/or the US | Korean product using US-origin components | **Most common: Criterion C — Product-Specific Rules** For each HS code, KORUS specifies what transformation must occur in Korea for the product to qualify. Common rules: 1. **Tariff shift** — The finished product must have a different HS heading (4-digit) or subheading (6-digit) than its non-originating inputs 2. **Regional Value Content (RVC)** — A minimum percentage of the product's value must originate in Korea/US 3. **Combination** — Both a tariff shift AND minimum RVC **RVC Calculation Methods:** Build-down method: RVC = (Adjusted value - Non-originating materials) / Adjusted value × 100 Build-up method: RVC = Originating materials / Adjusted value × 100 Most product-specific rules require 35-55% RVC depending on the product. ### KORUS Origin Example: K-Beauty Skincare A Korean skincare product (HS 3304.99) uses: - Korean-produced packaging: $2.00 - Korean water and processing: $3.00 - Japanese botanical extracts: $4.00 - French fragrance compounds: $1.50 - Korean labor and overhead: $5.00 - Total adjusted value: $15.50 Product-specific rule requires: Change to heading 3304 from any other heading Japanese extracts (HS 1302) → Korean skincare (HS 3304) = tariff shift achieved ✓ Result: Product qualifies for KORUS. Enters US duty-free instead of 0-4.9% MFN rate. ## Shipping from South Korea to the US ### Ocean Freight Korea's logistics infrastructure is excellent. Busan (the primary export port) offers: - Direct sailings to all US coasts multiple times per week - Competitive rates due to high vessel traffic - Efficient customs processing (Korea Customs Service is highly digitized) **Route Options:** | Route | Transit Time | Carriers | |-------|-------------|----------| | Busan → LA/Long Beach | 12-15 days | Maersk, MSC, HMM, ONE, Evergreen | | Busan → Oakland | 13-16 days | Same carriers | | Busan → Seattle/Tacoma | 11-13 days | Same carriers | | Busan → New York (Panama) | 25-30 days | Most major carriers | | Busan → Savannah | 27-32 days | Select carriers | **Current Rate Estimates (2026):** | Container | West Coast | East Coast | |-----------|-----------|------------| | 20ft FCL | $1,800-$3,500 | $3,000-$5,500 | | 40ft FCL | $2,500-$5,000 | $4,500-$8,000 | | 40ft HC | $2,700-$5,200 | $4,800-$8,500 | | LCL (per CBM) | $80-$150 | $120-$200 | Rates vary significantly by season, carrier, and contract terms. Q3-Q4 (peak season) typically 30-50% higher. ### Air Freight Incheon International Airport (ICN) is one of Asia's premier cargo hubs: | Route | Flight Time | Transit Time (total) | |-------|-------------|---------------------| | ICN → LAX | 11h | 3-5 days | | ICN → JFK | 14h | 4-6 days | | ICN → ORD (Chicago) | 13h | 4-6 days | | ICN → ATL | 14h | 4-6 days | **Air freight rates:** $3.50-$8.00 per kg depending on volume, commodity, and season. **When to use air vs. ocean:** - Air: High-value, low-weight goods (semiconductors, cosmetics, electronics components) - Ocean: Heavy, bulky goods (machinery, auto parts, steel, chemicals) - Express: Samples, urgent parts, documents ### Korean Logistics Partners Major Korean freight forwarders and logistics companies: - Pantos Logistics (LG subsidiary) - CJ Logistics - Hyundai Glovis - Samsung SDS - Hanjin Logistics ## Customs and Documentation ### Required Documents | Document | Who Provides | Purpose | |----------|-------------|---------| | Commercial invoice | Korean exporter | Declares value and terms of sale | | Packing list | Korean exporter | Physical description of shipment | | Bill of lading / AWB | Carrier | Proof of shipment | | ISF (10+2) | You or your broker | Ocean security requirement — file 24h before departure | | KORUS Certificate of Origin | Exporter/producer/importer | Claim preferential duty rate | | Entry summary (CBP 7501) | Your customs broker | Formal customs declaration | ### Product-Specific Requirements **Electronics (Samsung, LG, etc.):** - FCC certification required for RF-emitting devices - UL or equivalent safety listing - Energy Star compliance if applicable - DOE energy efficiency standards for appliances **Vehicles and auto parts:** - FMVSS (Federal Motor Vehicle Safety Standards) compliance - EPA emissions certification - DOT compliance for tires, glass, lighting - NHTSA registration **Cosmetics and skincare (K-beauty):** - FDA cosmetic registration (facility and product) - Ingredient labeling per FDA regulations - No FDA pre-market approval needed (cosmetics are post-market regulated) - Color additives must be FDA-approved **Food products (Korean snacks, noodles, beverages):** - FDA prior notice (submit before arrival) - FSMA compliance for your facility - Nutrition Facts labeling - Ingredient panel in English - Some items require USDA inspection (meat, poultry, eggs) **Lithium-ion batteries:** - UN38.3 testing certification - DOT/IATA hazmat shipping requirements - CPSC compliance for consumer products containing batteries ## Section 232: Steel and Aluminum Quota In 2018, the US imposed Section 232 tariffs (25% on steel, 10% on aluminum) on most countries. Korea negotiated a quota arrangement instead of paying the tariff: ### How the Korean Steel Quota Works - Korea receives an annual quota for steel exports to the US (approximately 2.63 million metric tons) - Steel within the quota enters WITHOUT paying the 25% Section 232 tariff - Steel exceeding the quota pays the full 25% - The quota is managed by categories — certain steel products have sub-quotas - Korean exporters must obtain quota allocation from the Korean government **What this means for importers:** - If your Korean steel supplier has quota allocation → you save 25% - If quota is exhausted → you pay 25% Section 232 on top of any other duties - Quota availability typically tightens toward year-end (October-December) - Verify quota status with your supplier before ordering ### Aluminum Korea's aluminum quota arrangement is similar but less restrictive since Korean aluminum exports to the US are smaller in volume. ## Finding and Vetting Korean Suppliers ### Where to Find Korean Suppliers 1. **Korea Trade-Investment Promotion Agency (KOTRA)** — Government export promotion agency with offices in major US cities. Free matchmaking service. 2. **EC21.com** — Korea's largest B2B marketplace 3. **Tradekorea.com** — KITA (Korea International Trade Association) platform 4. **Korea Export Buying Offices** — Many Korean manufacturers maintain US sales offices 5. **Industry trade shows** — CES (electronics), Cosmoprof (beauty), IMTS (machinery) 6. **Alibaba/Global Sources** — Some Korean suppliers list here, though these platforms are China-dominant ### Vetting Checklist | Check | How | Why | |-------|-----|-----| | Company registration | Request Korean business registration certificate | Verify legal entity | | Export license | Ask for export business license number | Confirms export authority | | Factory audit | Use KOTRA verification or third-party (SGS, BV) | Verify production capability | | Financial stability | Korean credit rating (NICE, KIS) | Ensure stability | | References | Request US customer references | Verify track record | | Certifications | ISO, IATF, KS marks | Quality system verification | | Samples | Order and test before bulk order | Verify quality firsthand | ### Korean Business Culture Tips - **Formal communication** — Use titles and family names initially - **Relationship-driven** — In-person meetings matter for large orders - **Hierarchy** — Decisions come from senior management - **Payment terms** — Korean companies typically accept T/T (wire transfer) and L/C; some accept 30-60 day terms for established relationships. For KRW or USD wire transfers, use Wise Business instead of your bank to save 1-3% on exchange rate markups - **Contracts** — Korean companies generally honor contracts well; legal enforcement is reliable - **Language** — Large exporters have English-speaking staff; smaller firms may need an agent ## Cost Analysis: Korea vs. China vs. Other Sources ### When Korea Wins | Scenario | Korea Advantage | |----------|----------------| | KORUS-eligible goods | 0% duty vs. 0-25% MFN from non-FTA countries | | Section 301 avoidance | Korean goods don't face China-specific 301 tariffs (7.5-100%) | | Quality-sensitive products | Korean manufacturing quality often higher than SE Asian alternatives | | IP-sensitive products | Strong Korean IP protection vs. risk in some countries | | Auto parts | KORUS + proximity to Korean OEMs in the US | | Electronics components | Samsung/SK ecosystem; cutting-edge technology | ### When China or Others Win | Scenario | Alternative Advantage | |----------|----------------------| | Pure cost play (low-value goods) | China/Vietnam still cheaper on labor-intensive goods | | Commodities | China's scale brings lower unit costs on basic goods | | Textiles/garments | Vietnam, Bangladesh offer lower costs | | Tropical agricultural products | Southeast Asia, Latin America | ### Total Landed Cost Comparison Example Importing $100,000 of industrial valves (HS 8481): | Source | Unit Cost | Freight | Duty | Section 301 | Total | |--------|----------|---------|------|-------------|-------| | Korea (KORUS) | $100,000 | $3,000 | $0 | $0 | $103,000 | | China | $85,000 | $2,500 | $4,250 (5%) | $21,250 (25%) | $113,000 | | India | $90,000 | $3,500 | $4,500 (5%) | $0 | $98,000 | | Germany | $130,000 | $4,000 | $0 (duty-free under HTS) | $0 | $134,000 | In this example, Korea offers the second-lowest landed cost despite higher unit price than China — because KORUS eliminates the duty and there are no Section 301 tariffs. ## Common Mistakes to Avoid ### 1. Not Claiming KORUS Preferences Many importers don't realize their Korean goods qualify for duty-free treatment and pay full MFN rates unnecessarily. If your goods are from Korea, always check KORUS eligibility. ### 2. Assuming All Korean Goods Qualify Just because goods are shipped from Korea doesn't mean they qualify for KORUS. Products assembled in Korea using primarily Chinese components may not meet Rules of Origin. Verify with your supplier. ### 3. Ignoring the Certificate of Origin Without proper origin documentation, CBP can deny your KORUS claim. Even though it's self-certified, the certification must contain all required data elements and be available upon request. ### 4. Missing the ISF Deadline For ocean shipments, [ISF must be filed 24+ hours before vessel departure](/blog/isf-filing-guide). Miss this and you face $5,000-$10,000 penalties. Korean shipping is fast — don't wait until the last minute. ### 5. Forgetting Section 232 Steel Quotas If importing Korean steel, verify your supplier has quota allocation. Running into an exhausted quota after shipping means an unexpected 25% tariff. ### 6. Not Factoring Korean Won Fluctuations The KRW/USD exchange rate can swing 10-15% annually. Build currency risk into your pricing or use hedging strategies. ## Step-by-Step: Your First Korean Import 1. **Identify your product and HS code** — Use our [HS Code Lookup guide](/blog/how-to-find-hs-code) 2. **Check KORUS eligibility** — Verify preferential rate and Rules of Origin requirements 3. **Find Korean suppliers** — Use KOTRA, trade platforms, or industry contacts 4. **Request samples and quotations** — Specify Incoterms (FOB Busan is common) 5. **Negotiate terms** — Price, payment, delivery schedule, quality standards 6. **Arrange logistics** — Choose ocean or air; engage freight forwarder 7. **Secure Certificate of Origin** — Have exporter prepare KORUS self-certification 8. **File ISF** — At least 24 hours before vessel departure (ocean only) 9. **Clear customs** — Your broker files entry claiming KORUS preferences 10. **Receive goods** — Inspect, warehouse, distribute ## Related Resources - [Certificate of Origin Guide](/blog/certificate-of-origin-guide) — detailed KORUS certification requirements - [ISF Filing Guide](/blog/isf-filing-guide) — mandatory for ocean shipments from Korea - [Ocean Freight vs Air Freight](/blog/ocean-freight-vs-air-freight) — choosing the right mode - [FOB vs CIF](/blog/fob-vs-cif-comparison) — negotiating Incoterms with Korean suppliers - [Customs Clearance Process](/blog/customs-clearance-process) — what happens when your Korean goods arrive
