Design cross-border logistics strategies including direct mail, overseas warehousing, and bonded warehouse models for international e-commerce. Use this skill when the user needs to ship products internationally, choose a logistics model for cross-border sales, optimize shipping costs, or set up fulfillment in a foreign market — even if they say 'ship to Southeast Asia', 'overseas warehouse vs direct shipping', 'customs clearance', or 'reduce international shipping time'.
IRON LAW: Return Logistics Costs 3-5× More Than Outbound — Budget for It or Die
Agents plan outbound shipping costs but systematically ignore returns.
Cross-border return rates run 15-30% for apparel, and each return costs
3-5× the outbound shipment (reverse customs, restocking, re-export duties,
currency loss). If your margin can't absorb a 20% return rate at 4× cost,
the overseas warehouse model is a cash trap regardless of forward volume.
Calculate the break-even return rate BEFORE committing to a fulfillment model.
| Model | How It Works | Delivery Time | Cost per Order | Min. Volume | Best For |
|---|---|---|---|---|---|
| Direct Mail (直郵) | Ship each order from Taiwan to customer | 7-21 days | High ($8-25) | 1 order | Testing market, low volume, high-value items |
| Pre-stock inventory in destination country, ship locally |
| 1-5 days |
| Low ($2-5 local) + warehousing |
| 100+ units/month |
| Proven demand, competitive delivery needed |
| Bonded Warehouse (保稅倉) | Store in bonded zone, clear customs per-order | 3-7 days | Medium ($5-10) | 50+ units/month | Duty deferral, uncertain demand |
Monthly orders to one country < 50 → Direct Mail
Monthly orders 50-500 → Consider Bonded Warehouse
Monthly orders > 500 → Overseas Warehouse justified
| Factor | What to Know |
|---|---|
| De minimis threshold | Below this value, no import duty (varies: $75 in most SEA, $400 in US) |
| HS Code | Product classification code determines duty rate. Get this RIGHT — wrong HS code = penalties |
| Landed cost | Product cost + shipping + insurance + duties + taxes = what customer actually pays |
| Documentation | Commercial invoice, packing list, certificate of origin, product-specific certificates |
| Restricted items | Food, cosmetics, electronics, medical devices often need import permits |
| Type | Service | Cost | Control |
|---|---|---|---|
| 3PL (e.g., ShipBob, Boxme) | Full service: storage, pick-pack, ship | $$-$$$ | Low (outsourced) |
| Marketplace fulfillment (Shopee/Lazada warehouse) | Platform handles logistics | Commission-included | Very low |
| Self-operated warehouse | Your own warehouse + staff | $$$$ upfront | Full |
| Drop-shipping | Supplier ships directly | Lowest | None |
Phase 1: Direct Mail (Market Testing)
Phase 2: Transition to Overseas Warehouse (Scaling) 5. Select 3PL or marketplace fulfillment in target market 6. Ship initial inventory batch 7. Integrate order management: your system → warehouse WMS 8. Monitor: fill rate, delivery time, return rate
Phase 3: Optimize 9. Analyze SKU-level demand to optimize pre-stocking 10. Negotiate volume rates with logistics partners 11. Evaluate bonded warehouse for duty optimization
