Korean cross-border customs — the headline
When you buy from a foreign retailer and import into Korea for personal use, you get a duty-free allowance. As of 2026:
- US-origin: ≤ $200 (Korea–US FTA)
- Other origins: ≤ $150
- For personal use, one person only
- Bundling: shipments arriving same day, same carrier, same recipient are evaluated together
Those four lines are the core of Korea Customs Service rules (customs.go.kr). Everything below is application detail. This article walks through the threshold, the bundling pitfall, customs-code registration, and the return-refund process, drawn from real operator experience. For your specific case, Korea Customs (call 125) or a licensed customs broker is the most accurate authority.
Tax above the threshold
When you exceed the threshold, tax applies to the whole amount, not just the excess. This is the most commonly misunderstood rule.
| Tax | Rate (most items) | Note |
|---|---|---|
| Customs duty | 6.5% (0–3% with FTA) | 0–30% by HS code |
| Value-added tax (VAT) | 10% | On duty-inclusive total |
| Excise tax | 5–30% | Luxury (watches, bags, perfume) |
| Education surtax | 30% of excise | Only when excise applies |
Worked example — a $250 item from the US (over $200):
```
Duty: $250 × 6.5% = $16.25
VAT: ($250 + $16.25) × 10% = $26.63
Total tax: $42.88 (~₩58,000)
```
Items eligible for the Korea–US FTA see duty drop to 0–3%. Sellers like Amazon, iHerb, and Walmart issue a Certificate of Origin (CO) automatically, so the benefit applies without action. Smaller sellers may not — verify before checkout.
The bundling pitfall — most common mistake
Same day + same carrier + same recipient = bundled. Customs assesses the combined value, not each shipment individually.
Real cases
- Case A: Amazon $130 + Walmart $80 arriving same day → bundled $210 → exceeds even the US $200 threshold → taxed
- Case B: Amazon $130 on Apr 10 + Walmart $80 on Apr 11 → separate → both duty-free
- Case C: Same-day US Amazon $150 + Japan Rakuten $50 → US $200 vs Japan $150 thresholds → different origins applied separately → both duty-free
You can also avoid bundling by using different carriers. Amazon via UPS and eBay via DHL on the same day are treated separately. The trade-off: you can't always control which carrier a seller chooses.
If you have several orders queued, one calendar day of separation is enough to split them. But the relevant date is Korea entry, not seller ship-out, so the split only firms up after tracking confirms arrival.
Personal Customs Code — issuance and use
Since 2025, every cross-border personal import must include a Personal Customs Code. Without it, the package can't clear.
How to register (5 minutes)
- Visit Korea Customs UNIPASS (unipass.customs.go.kr)
- Identity-verify (Joint Certificate or mobile carrier auth)
- Menu → "Personal Customs Code" → Apply
- Receive a 13-character code starting with "P" instantly
- Available on the Korea Customs mobile app
It's free, takes about 5 minutes, and is essentially permanent once issued.
Usage rules
- Enter the code in the seller's address form (e.g., Amazon's "Personal Customs Code" field)
- Code holder name and recipient name must match
- Borrowing another person's code is illegal — both parties face penalty
- Lost? Look it up again on UNIPASS instantly
In a multi-person household, register a code for each member. The duty-free allowance applies per person. A family of four can clear four separate $150 packages on the same day.
Auto-FTA sellers vs non-FTA sellers
Even US-origin items only get the FTA preferential duty if the seller issues a Certificate of Origin (CO).
| Seller | Auto-FTA | Note |
|---|---|---|
| Amazon.com | Yes | Auto at checkout |
| iHerb | Yes | Strong on supplements |
| Walmart | Yes | |
| eBay | Mixed | Per-seller — verify |
| Costco.com | Yes | |
| Apple.com | Yes | |
| Best Buy | Yes | |
| Small independent sellers | Usually no | 6.5% duty applies in full |
FTA savings example:
- $300 item → duty drops from 6.5% to 0–3% → saves ~$10–20
- VAT (10%) is unaffected
The Cross-Border Customs Calculator has an FTA toggle for instant comparison.
Item-specific limits — even FTA can't waive these
Beyond the threshold, certain items carry independent restrictions.
| Item | Limit / rule |
|---|---|
| Food, supplements | 6 bottles or 6kg |
| Cosmetics | 5 units per SKU |
| Medication | Prescription required, 6-bottle cap |
| Electronics (Bluetooth/WiFi) | 1 unit RF-cert exempt |
| Luxury (bags, watches) | $150 ceiling even from US (no FTA) |
| Alcohol | 1 bottle ≤ 1L (duty-free) |
| Tobacco | 200 sticks (1 carton) |
| Plants / seeds | Quarantine required |
| Quasi-drugs | 6-bottle cap |
| Health functional food | 6-bottle cap |
Luxury goods (bags, watches) do not get the FTA waiver even from US sellers. A $180 watch from the US is taxable. For cosmetics, medication, and food, exceeding the count limit can result in seizure or return — order in compliant batches.
Refund process when returning
You can request a duty/VAT refund within 30 days of import.
Steps
- Initiate return with seller; receive return label
- Issue an Export Declaration (broker or self-filed)
- Confirm the package exits Korea
- File refund on UNIPASS
- Refund deposits in 4–8 weeks
Refund odds by seller
| Seller | Refund odds |
|---|---|
| Amazon | High (auto return labels) |
| iHerb | Low (returns are hard) |
| Sephora | Low |
| Apparel (ASOS, Nordstrom) | Medium |
You can file the refund yourself, but if the seller doesn't accept the return, you can't ship it back. Verify return policy before large purchases.
Cost simulation — real numbers
Plug into Cross-Border Customs Calculator:
```
Item price: $250
Shipping: $30
Insurance: $5
Origin: US (FTA applies)
```
Output:
- Taxable base: $285 (item + shipping + insurance)
- Duty: $0 (FTA)
- VAT: $28.5
- Total tax: ~₩38,000
Same item, FTA not applied (small seller)
- Duty: $18.5 (6.5%)
- VAT: $30.4
- Total tax: ~₩65,000
FTA alone saves about ₩27,000 on this transaction. All else equal, prefer FTA-auto sellers.
FAQ
Q. $190 item + $20 shipping = $210 from the US — is it duty-free?
No. The $200 threshold includes item + shipping + insurance. At $210 the whole amount is taxable.
Q. Can I borrow a family member's customs code?
No — it's illegal under the Customs Act. Both you and the lender face penalties. Register a code per person.
Q. Are EMS and FedEx limits different?
No — the duty-free threshold is identical. But express carriers (FedEx, DHL, UPS) add their own brokerage fee, typically $8–25. EMS via Korea Post has a lower fee structure.
Q. What about laptops?
Most will exceed $150–200. Also, RF certification exemption is one device only. Laptops, tablets, and smartphones are usually taxable — pre-simulate with the Cross-Border Customs Calculator.
Q. Two orders from the same seller — bundled?
If they arrive in Korea the same day via the same carrier, yes. One day's gap, separate. The relevant date is Korean entry date, not order date.
Q. One family member's name, $400, used by two people?
Allowance is per person. $400 in one person's name → over threshold → taxed. If both have customs codes, two $200 orders to each person can both clear duty-free.
Q. Got a counterfeit or defective item — what now?
If you paid by credit card, file a chargeback through your issuer. Otherwise, use the seller's dispute process (Amazon A-to-z, eBay Money Back Guarantee, etc.).
Five common beginner pitfalls — what we see in support questions
The most-repeated questions we get on the customs tool, organized.
Pitfall 1 — Confusing Amazon's "Estimated Import Fees Deposit" with Korean tax
Amazon shows an "Import Fees Deposit $XX" line at checkout. That's Amazon's prepaid amount, not Korean tax. Sometimes Amazon settles the Korean fee on your behalf and you see no further charge; sometimes Korean customs bills you separately. Keep the receipt either way.
Pitfall 2 — Splitting orders without splitting arrival days
Buying twice "each under $150" doesn't help if the seller bundles both into the same outbound shipment. Bundling is by arrival in Korea, not payment date. Space the orders out by a few days so they don't land together.
Pitfall 3 — Thinking a US-IP checkout changes the threshold
Allowances are by origin + destination, not where you check out. Using a US VPN doesn't unlock the US-resident threshold — Korean rules still apply to your import.
Pitfall 4 — Paying with a family member's card but receiving under your code
If the recipient name on the customs code is yours, the shipment is yours for tax purposes — regardless of whose card paid. Mismatches between payer and recipient names can also trigger extra inspection.
Pitfall 5 — Foreign sellers that look like Korean retailers
Korean-language site with KRW pricing doesn't mean it's a Korean seller. If the actual fulfillment is from abroad, cross-border rules apply. Check the seller address and payment currency at checkout.

Bottom line — threshold + bundling + FTA seller
Three things drive 90% of cross-border tax optimization:
- Know the threshold ($200 US / $150 others)
- Avoid bundling (same day, same carrier)
- Prefer FTA-auto sellers (Amazon, iHerb, Walmart, etc.)
Register your customs code first — it takes 5 minutes — then run any large purchase through the calculator before checkout. For unusual cases, call Korea Customs (125) or consult a licensed customs broker.
