Korea Customs Duty + VAT Guide 2026 — $150/$200 De Minimis, KORUS FTA, KFDA Limits

📅 Published 2026.05 · By kr-utils · ~10 min read

Buying from Amazon US, iHerb, AliExpress, or Rakuten while living in Korea? Most personal-use orders under $200 USD from the US (KORUS FTA) or $150 USD-equivalent elsewhere clear customs duty- and VAT-free under Korea's 목록통관 (list clearance) procedure — automatically, no action required. But cross the de minimis even by $1 and the entire shipment gets taxed. Some categories (supplements, cosmetics, medications) also need KFDA approval regardless of value. This guide walks through Korea's customs framework: the de minimis thresholds, the personal customs clearance code (개인통관고유부호) required for online imports, what gets held and why, and how to claim refunds when customs gets it wrong.

1. Korea's customs framework — duty + VAT on imports

Korea Customs Service (관세청, customs.go.kr) imposes two taxes on imported goods exceeding the de minimis threshold:

• Customs duty (관세) — varies by HS code (Harmonized System). Typical rates for personal goods: clothing 13%, electronics 0–8%, supplements 5%, cosmetics 6.5%, food 8–30% (varies). Search the official tariff at customs.go.kr → 관세율 검색.
• VAT (부가가치세) — 10% on (CIF + customs duty). VAT compounds on top of duty. Books, magazines, and some printed materials are VAT-exempt.

Total tax for most personal goods ends up around 18–22% of CIF once both apply. The base for duty is CIF (Cost + Insurance + Freight), not just the goods price — so a $180 order with $30 shipping has a CIF of $210, putting it over the $200 KORUS threshold.

2. De minimis thresholds — $200 (US) / $150 (elsewhere)

Korea exempts duty and VAT on small personal-use shipments below these thresholds:

Critical traps:

• Per shipment, not per month. You can receive multiple sub-threshold packages in the same month, each independently assessed. But repeated same-supplier patterns trigger commercial scrutiny.
• Cross the line = entire value taxed. A $205 US shipment is taxed on the full $205 (not just the $5 excess). Stay just under the threshold, or accept that the whole order is dutiable.
• Shipping counts. "Free shipping" sites bundle shipping into the goods price (no effect on CIF). Sites that charge shipping separately ($180 goods + $30 ship = $210 CIF) push you over.
• US origin vs US shipper. The $200 KORUS threshold applies to goods of US origin (Made in USA). A package shipped from a US warehouse but containing Chinese-made goods may be treated under the $150 rate depending on customs interpretation.

3. Personal Customs Clearance Code (개인통관고유부호)

Every Korean resident (Korean nationals and ARC-holding foreigners) needs a free, one-time-issued personal customs clearance code to import online purchases. Without it, packages get held.

3.1 How to register

1. Go to unipass.customs.go.kr
2. Click 개인통관고유부호 발급 (Issue Personal Customs Clearance Code)
3. Authenticate with ARN/RRN + Korean phone number + email
4. Receive your code instantly: format P-XXXXX-XXXXX-X (12 digits)

The code is permanent — register once, use forever. Foreigners must have an ARN (Alien Registration Number, your ARC number) to register; D-2 students, E-series workers, F-series long-term residents all qualify.

3.2 How to use it

At checkout on overseas shopping sites:

• Amazon US — enter under "Customs ID" or "Tax ID" during shipping address setup. Save once in your profile.
• iHerb — Korean Customs Clearance ID field at checkout.
• AliExpress / Taobao — Personal customs clearance code field (Chinese sites usually require it).
• Rakuten / Yahoo Japan — same field, sometimes labeled in Japanese.

For packages already in transit without the code, you can usually contact the carrier (DHL, FedEx, EMS, Korean Post) and provide the code to clear customs.

4. KFDA restrictions — items that trigger inspection

Some categories require KFDA (식품의약품안전처, Korea Food and Drug Administration) approval regardless of customs value. These are the items most often held or returned:

• Supplements / vitamins — high-dose vitamin A (>10,000 IU/serving), melatonin (some forms), ephedra, restricted herbal compounds (e.g., comfrey, kava in some forms). iHerb pre-filters Korea-restricted items at checkout.
• Food — meat products (banned without specific permits), processed foods with prohibited additives, raw dairy. Personal use 5 kg / $150 limit per shipment for most foods.
• Cosmetics — most personal-use cosmetics OK; products with claims like "anti-aging," "medicinal" need KFDA registration. Personal use limit: typically 6 items per type.
• Medications — prescription drugs require a Korean doctor's prescription. Over-the-counter generally allowed in small personal quantities (typically 6-month supply max).
• Contact lenses — require Korean optometrist prescription. Cosmetic colored lenses often blocked entirely.
• Medical devices — blood pressure monitors, thermometers, etc. need KFDA approval. Most US-brand consumer devices have local distributors.

For up-to-date restrictions, check mfds.go.kr or call MFDS at ☎ 1577-1255. The free Korea Consumer Agency helpline ☎ 1372 also has English-speaking staff who can advise.

5. 목록통관 (list clearance) vs 정식통관 (formal declaration)

Korea handles imports under two procedures depending on value and complexity:

5.1 목록통관 (List Clearance) — the default for personal purchases

• Eligibility: personal-use, under $200 US / $150 elsewhere, no restricted items
• Process: customs reviews carrier's manifest list only — no invoice required, no declaration form
• Speed: 1–3 business days typical clearance time
• What you do: nothing — package arrives at your door
• Covers: ~95% of Amazon, iHerb, AliExpress, Rakuten personal orders

5.2 정식통관 (Formal Declaration) — for over-threshold or flagged items

• Triggered when: value exceeds de minimis, restricted item suspected, missing customs code, or commercial pattern flagged
• Process: customs sends notice (English available) requesting invoice, ARN, 자가사용 (personal use) declaration, possibly KFDA-related certificates
• Speed: 1–4 weeks typical, longer if KFDA review needed
• What you do: log into unipass.customs.go.kr, upload invoice + select "Personal use 자가사용," pay duty + VAT via online banking or card. Korean Customs Service issues a payment slip with exact amounts.
• Penalty for missing deadline: package returned to sender (you may forfeit shipping fees and the original purchase price) or destroyed if return is impractical

For very high-value shipments (over ₩3M) or repeated commercial-pattern flags, customs may require a licensed customs broker (관세사) at additional cost ($30–100 typical fee per shipment).

6. Realistic worked examples

Concrete scenarios to calibrate expectations:

* Approximate. Use the Korean Customs Calculator with your specific HS code and CIF for an accurate estimate.

7. Refunds, disputes, and broker services

If customs overcharges or misclassifies your shipment, you have legal recourse.

7.1 Refund grounds (Customs Act §46)

• Wrong HS code — higher-duty category applied than correct (e.g., a hobby item classified as commercial)
• Overvaluation — customs valued the goods higher than the actual invoice price
• Missed FTA rate — KORUS / EU / ASEAN preferential rate not applied when eligible
• Duplicate charge — same shipment charged twice (rare but happens)

7.2 Refund process

1. Time limit: within 5 years of duty payment
2. Where to file: unipass.customs.go.kr → 관세환급 신청, or in person at any Korean Customs office
3. Required documents: original invoice, payment receipt (자동납부 영수증), shipping documents, supporting evidence (e.g., HS code reclassification justification)
4. Processing time: 2–8 weeks typical
5. Outcome: refund to your registered Korean bank account, or credit against future duty payments

7.3 When to hire a customs broker (관세사)

For straightforward personal-use shipments, self-service via unipass.customs.go.kr is enough. Consider hiring a broker (~$30–100/case) when:

• Disputed amount exceeds ₩1,000,000
• Multiple HS codes / complex classification
• FTA origin verification requires technical analysis
• You don't read Korean and the dispute requires written submissions

Find licensed brokers at Korea Customs Brokers Association (kcba.or.kr).
