Choosing how you pay a Korean supplier is as important as choosing the supplier. This 2026 guide compares T/T, L/C, D/P, escrow, and open account so you can protect every transaction and pick the safest, most cost-effective option for your order size and trust level.
Payment Methods Overview
| Method | Security (Buyer) | Cost | Speed | Best For |
|---|---|---|---|---|
| T/T (30/70) | Medium | Low ($20-50) | Fast (1-3 days) | Most common, established suppliers |
| T/T (100%) | Low | Low ($20-50) | Fast | Trusted suppliers only |
| L/C | Very High | High ($300-800) | Slow (7-14 days) | Large orders ($50K+), new suppliers |
| D/P | Medium-High | Medium ($100-300) | Medium (5-10 days) | Middle ground |
| Escrow | High | Medium (2-5%) | Medium | E-commerce, small orders |
| PayPal | High | High (3-5%) | Fast | Samples only (<$3,000) |
T/T (Telegraphic Transfer / Wire Transfer)
What is T/T?
Definition: A bank-to-bank electronic funds transfer sent over the SWIFT network. It is by far the most common payment method for Korea imports, used in roughly 85% of transactions thanks to its low cost and 1-3 day settlement.
T/T Payment Structures
30/70 T/T (Standard)
Structure:
- 30% deposit before production
- 70% balance before shipment
Pros:
- Balanced risk shared by both parties
- Withholding 70% keeps the supplier motivated to deliver quality
- Low cost ($20-50 per wire)
- Industry standard (easy to negotiate)
Best for:
- First 1-3 orders with new supplier
- Orders $5,000-$100,000
- Verified suppliers with good reputation
50/50 T/T (Higher Risk)
Structure:
- 50% deposit before production
- 50% balance before shipment
When suppliers request:
- Large orders requiring significant materials
- Custom products (non-standard)
- New/small suppliers with cash flow concerns
100% T/T in Advance
Structure:
- 100% payment before production/shipment
Only use if:
- Trusted supplier (5+ successful orders)
- Small amount you can afford to lose
- Supplier referred by trusted source
Progressive Payments
Structure:
- 30% deposit upon order
- 30% upon production midpoint
- 40% before shipment
When used:
- Very large orders ($100,000+)
- Long production time (3+ months)
- Complex products requiring multiple stages
Advantage: Tying each tranche to a milestone lets you run quality checks throughout production and hold back funds if work falls behind.
How to Send T/T
Step 1: Get Bank Details
Required information:
- Bank name (e.g., Shinhan Bank)
- Bank address (Seoul branch)
- Account holder name (MUST match company)
- Account number
- SWIFT/BIC code (e.g., SHBKKRSE)
Step 2: Initiate Wire Transfer
Online banking:
- Find "International wire transfer"
- Enter supplier's bank details
- Specify amount, currency (USD or KRW)
- Review fees
- Authorize and save confirmation
Important: Always keep the wire transfer confirmation (MT103) as your proof of payment.
Step 3: Notify Supplier
Send email with:
- Amount sent
- Date sent
- Order reference number
- Bank confirmation attached
Ask the supplier to confirm receipt within 2-3 business days.
Step 4: Confirmation
Typical timeline:
- 1-3 business days for USD → KRW conversion
- Supplier confirms: "Payment received"
- Production starts
- If >3 days, contact supplier and bank
T/T Costs & Fees
L/C (Letter of Credit)
What is L/C?
Definition: A bank guarantee that pays the supplier only if the presented documents exactly match the agreed terms. Payment hinges on the DOCUMENTS, not the goods themselves, so airtight terms matter more than trust.
How L/C Works
Apply for L/C at your bank with good credit or collateral (100-110% of L/C value). Approval: 1-5 days.
Your bank sends L/C via SWIFT to supplier's Korean bank. Supplier reviews terms and accepts or requests amendments.
Supplier manufactures goods and arranges shipment. Obtains required documents (B/L, invoice, packing list, certificates).
Supplier presents documents to their bank. Bank examines if documents match L/C terms exactly.
If compliant, bank pays supplier. Your bank debits your account. Documents sent to you.
Use Bill of Lading to claim goods from shipping line. Use documents for customs clearance.
L/C Costs
Example: $50,000 L/C
- Issuance fee: $400
- Handling fee (0.25%): $125
- Courier: $75
- Amendment fee (if needed): $100-200
Total: $600-800 = 1.4-1.8% of transaction
That makes an L/C roughly 15-30x more expensive than a T/T (about $50).
L/C Pros & Cons
Pros
- Secure for both parties (bank guarantee)
- Supplier confident they'll be paid
- You control payment (documents must match)
- Good for new suppliers, large orders
Cons
- Expensive ($700+ vs $50 for T/T)
- Slow (7-14 days vs 1-3 for T/T)
- Complex (requires expertise)
- Documents ≠ quality (still pay if compliant)
- 70% of L/Cs have initial discrepancies
When to use L/C: First-time supplier with large order (>$50K), high-risk countries, supplier insists.
When to skip L/C: Established supplier (3+ orders), Korea (low-risk country), small orders (<$10,000), speed matters.
Other Payment Methods
D/P (Documents against Payment)
A simpler, cheaper alternative to an L/C: the shipping documents are released to you only after you pay, but without a full bank guarantee.
Cost: $100-300 total
Best for:
- Medium trust level (between T/T and L/C)
- Orders $10,000-$50,000
- Want security without L/C complexity
Escrow Services
A neutral third party holds your payment until the transaction is complete, letting you inspect and approve the goods before funds are released.
Cost: 2-5% of transaction
Best for:
- E-commerce small orders ($1,000-$10,000)
- First-time supplier (low trust)
- High scam risk industries
PayPal
Fast, near-instant payment with built-in buyer protection and dispute resolution, ideal for low-value purchases.
Cost: 3-5% fees (supplier usually absorbs)
Best for:
- Samples ($50-500)
- Very small orders (<$3,000)
- E-commerce purchases
Note: Many Korean suppliers decline PayPal because of its fees and chargeback risk, preferring T/T instead.
O/A (Open Account)
The supplier ships first and you pay later (Net 30/60/90). It rests entirely on trust, with no documents held against payment.
When suppliers offer:
- Long-term relationship (2+ years)
- Proven payment history (15+ on-time payments)
- Large customer (supplier values relationship)
Benefit: Maximum cash flow flexibility, since you can receive and even sell the goods before the invoice falls due.
Payment Security Best Practices
Verify Supplier Before Payment
7-Point Verification
- ✅ Business registration number verified
- ✅ Export capability confirmed
- ✅ Factory video tour completed
- ✅ Certifications verified (ISO, CGMP, etc.)
- ✅ References checked (2-3 past customers)
- ✅ Financial stability assessed
- ✅ Samples tested
Red Flags (Walk Away)
- ❌ Requests 100% upfront (new relationship)
- ❌ Unusually low price (40%+ below market)
- ❌ Pressure tactics ("Pay today or lose stock!")
- ❌ Personal bank account (name ≠ company)
- ❌ Bank in different country
- ❌ Refuses inspection
- ❌ Changes bank account suddenly
- ❌ Generic email (Gmail instead of company domain)
Use Inspection Before Final Payment
Standard practice for T/T 30/70:
- Pay 30% deposit
- Production completes
- Hire inspection company ($300-600)
- Inspector checks goods at factory
- If passes: Pay 70% balance
- If fails: Request corrections before payment
ROI: A $300-600 inspection can prevent a $10,000-$50,000 loss from a defective shipment. Release the 70% balance only AFTER inspection passes.
Payment Terms Progression

Established relationship, proven history
Stage 4: Strategic
Payment: Net 30-60

Currency Considerations
Why Use USD
- International standard for trade
- Korean banks easily convert USD ↔ KRW
- Invoices, quotes typically in USD
- Stable currency (less volatility than KRW)
- No confusion (both parties understand USD)

Common Payment Mistakes
Mistake 1: Paying 100% Upfront
Problem: Send $10,000 (100% payment). Supplier disappears or ships defective goods. No leverage.
Solution: Never pay 100% to a new supplier (cap it at 50%, ideally 30%). Keep the 70% balance as leverage until the goods pass inspection.
Mistake 2: Paying Before Samples
Problem: Pay 30% deposit before testing samples. Bulk order quality terrible, not as pictured.
Solution: Always order samples first ($50-500). Test thoroughly. Only pay deposit after sample approval.
Mistake 3: No Inspection Before 70%
Problem: Pay 70% immediately when supplier pressures. Goods arrive defective. Already paid 100%, supplier ignores complaints.
Solution: Hire inspection company ($300-600). Only pay 70% after inspection passes.
Mistake 4: Paying to Wrong Account
Problem: A scammer intercepts your email thread and swaps in fraudulent bank details, so you wire the money straight to their account.
Solution: Always verify bank details by phone on a known number, confirm the account holder name matches the company, and treat any sudden account change as a red flag.
