HS Code Classification
What it is: the Harmonized System Code, the international product classification standard used by 200+ countries. It determines your customs duty rate, FTA eligibility, trade statistics, and which regulations apply.
3304.99.00.00 (Example: Cosmetics) 33 = Chapter (Cosmetics) 3304 = Heading (Beauty/makeup products) 3304.99 = Subheading (Other) 3304.99.00 = 8-digit (Korea level) 3304.99.00.00 = 10-digit (Korea detailed)
How to Find HS Code
Method 1: Korea Customs
Visit: UNI-PASS HS Search
Search in Korean or English to confirm the official 10-digit Korea export HS code
Method 2: Ask Supplier

Always verify it independently - a wrong code means delays and penalties
Why HS Code Accuracy Matters

Common Export Issues & Solutions
Issue 1: Document Discrepancies
Problem: Invoice shows 1,000 units, packing list shows 1,050 units
Solution: Triple-check all documents match. Same descriptions, quantities, weights, values across all documents.
Issue 2: Wrong HS Code
Problem: Incorrect classification leads to rejection
Solution: Verify HS code accuracy before production. Check both Korea export code and destination import code.
Issue 3: Under-Valuation
Temptation: Declare lower value to help buyer save duties
Reality: 40% penalty + criminal charges. Insurance void. NEVER under-declare.
Issue 4: Missing Certificates
Problem: Health certificate not obtained for food products
Solution: Identify certificate requirements early. Apply 2-3 weeks before shipment.
