How to Ship from Korea to Amazon FBA: Sea Freight, Air, and Prep Center Guide

Overview: the Korea-to-FBA supply chain

Shipping from Korea to Amazon FBA involves more steps than domestic sourcing — but the process is well-established. Hundreds of Amazon sellers successfully run Korea-to-FBA supply chains for K-beauty, Korean food, electronics accessories, and other categories. This guide walks you through every step.

Step 1: Choose your shipping method

Method	Transit (Korea→US)	Cost estimate	Best for
Sea freight LCL (Less-than-Container Load)	18–25 days	$150–400/CBM	Regular restocks, 0.5–10 CBM
Sea freight FCL (Full Container Load)	18–25 days	$1,500–3,500/40ft	High volume, 15+ CBM
Air freight	5–7 days	$5–9/kg	High-value, time-sensitive, under 150kg
Express courier (DHL/FedEx/UPS)	3–5 days	$9–18/kg	Samples, urgent small restocks

Most FBA sellers use: Sea freight LCL for orders under 10 CBM (roughly 500–2,000 units of cosmetics), switching to FCL when monthly volumes exceed one 20ft container.

Step 2: Find a Korean freight forwarder

You need a freight forwarder based in Korea (or with a Korea office) to handle export customs, prepare shipping documents, and arrange the actual shipment. Key responsibilities:

• Export customs clearance (Korean customs)
• Bill of Lading or Airway Bill preparation
• Commercial Invoice and Packing List
• Certificate of Origin (for KORUS duty-free claim)
• Booking cargo space with shipping line or airline

What to ask a Korean forwarder:

1. Do you handle Korea-to-FBA shipments regularly?
2. Can you prepare FBA-compliant carton labels?
3. Do you have a US customs broker partner?
4. What is your handling fee for LCL?

Step 3: US import customs clearance

Your freight forwarder typically works with a US customs broker to clear your shipment. Key documents required:

• Commercial Invoice (with HS codes, declared value)
• Packing List
• Bill of Lading or Airway Bill
• Origin documentation when claiming a potentially available KORUS tariff preference
• FDA Prior Notice for covered food imports, subject to applicable exemptions (not generally for cosmetics)
• Any required certificates (HACCP, MFDS, etc.)

Import duty under KORUS FTA: KORUS FTA preference depends on tariff classification, rules of origin, documentation, and current additional duties. Confirm the entry-date rate with a licensed customs broker; do not assume that every shipment is duty-free.

Step 4: Ship direct to FBA or use a prep center?

Option A: Ship direct to Amazon FBA warehouse

Requires your Korean supplier to:

• Apply FNSKU barcodes to each unit
• Pack in FBA-compliant cartons (no overweight, correct dimensions)
• Apply Amazon's required carton labels
• Meet all FBA packaging requirements (poly bags, suffocation warnings, etc.)

Cost advantage: Saves $0.50–1.50/unit in prep center fees. Works well once you have an established relationship with a supplier who does FBA prep reliably.

Option B: Use a US prep center

Ship to a third-party prep center (3PL) in the US first. The prep center receives your goods, applies FNSKUs, re-packs if needed, and creates an FBA shipment.

Cost: $0.50–1.50 per unit for FNSKU labeling + $0.20–0.50 per unit for re-boxing if needed.

Best for: New suppliers (until you trust their FBA compliance), products that need English stickers or US-compliant labeling added, and first-time Korea-to-FBA shipments.

Step 5: FBA packaging compliance — Korean supplier checklist

Send this checklist to your Korean supplier before production:

• ✅ Unit dimensions and weight meet FBA limits (longest side ≤ 18", standard-size ≤ 20 lbs)
• ✅ FNSKU barcode applied to each unit (cover manufacturer barcode if present)
• ✅ Poly bag with suffocation warning for soft goods (warning text on bag if bag is 5" × 5" or larger)
• ✅ Set/bundle sold as single unit — outer packaging clearly marked "Sold as Set"
• ✅ Carton weight ≤ 50 lbs per box
• ✅ FBA shipment carton label applied (generated in Seller Central)
• ✅ No loose items or multiple SKUs in one shipping carton

Timeline: Korea-to-FBA typical total lead time

Stage	Duration
Production (ODM, existing formulation)	4–6 weeks
Quality inspection (optional but recommended)	3–5 days
Export packing + forwarder pickup	3–5 days
Sea freight transit (Korea→US West Coast)	18–22 days
US customs clearance	3–7 days
FBA check-in (after delivery to warehouse)	2–5 business days
Total (sea freight)	~10–12 weeks

Air freight alternative total: ~6–8 weeks (production + 1 week transit).

Common mistakes that cost FBA sellers money

• ❌ Assuming zero import duty without checking applicable tariffs and origin rules
• ❌ Skipping FDA Prior Notice for covered food imports when required — customs hold, potential recall
• ❌ Wrong carton dimensions or weight — FBA receives penalty or refuses shipment
• ❌ FNSKU applied over barcode incompletely — scanner reads wrong barcode, stranded inventory
• ❌ Not testing supplier's FBA packing quality on trial order — expensive to fix at scale
• ❌ Ignoring inventory lead time — 10–12 week Korea-to-FBA cycle requires ordering 2–3 months before stockout
