For e-commerce sellers, balancing inventory costs with delivery speed is a constant challenge. Relying solely on overseas warehouses ties up capital, while depending only on direct express shipping from China leads to unpredictable delivery times. The synergy between overseas warehouses and express lines creates a robust logistics model that combines the stability of local inventory with the flexibility of direct shipping.

Core Strategy: Base Stock + Emergency Replenishment

The Concept:
Maintain optimal inventory levels in overseas warehouses for regular sales, while using express lines for urgent replenishment and peak demand.

Implementation Framework:

Phase 1: Strategic Warehouse Placement & Base Inventory

• Warehouse Location Strategy:

  • USA Market: Los Angeles (West Coast), Memphis (Central), New Jersey (East Coast)

  • Europe Market: Rotterdam (Western EU), Warsaw (Eastern EU), Milan (Southern EU)

• Base Stock Calculation:

  • Maintain 4-6 weeks of inventory for steady-selling products

  • Keep 2-3 weeks of bestseller inventory as safety stock

• Shipping Method for Base Stock:

  • Route Example: Shenzhen → Los Angeles (Sea FCL)

  • Products: Home goods, furniture, seasonal items

  • Transit Time: 30-35 days

  • Cost Advantage: 60-70% cheaper than air freight

Phase 2: Express Line Integration for Demand Fluctuation

• Emergency Replenishment Scenarios:

  • Sudden sales spikes on online platforms

  • Stockouts of best-selling variants

  • New product launches requiring fast market testing

• Express Line Selection:

  • Route Example: Guangzhou → Frankfurt (Consolidated Express)

  • Transit Time: 7-10 days

  • Optimal Volume: 50-200 kg shipments

  • Cost Efficiency: 30-40% cheaper than commercial express

Operational Models for Different Business Scenarios

Model 1: Bestseller Support Model

• Application: Products with stable daily sales plus occasional spikes

• Warehouse Role: Handle routine orders and standard deliveries

• Express Role: Emergency replenishment during promotions

• Example:

  • Product: Smart home devices

  • Base Stock: 500 units in New Jersey warehouse

  • Express Trigger: Sales exceed 50 units/day during promotion

  • Response: Ship 200 units via express within 24 hours

Model 2: New Product Launch Model

• Application: Testing new products without committing to large inventory

• Warehouse Role: Minimal display stock for immediate shipping

• Express Role: Main replenishment channel during trial period

• Example:

  • Product: New electronic accessory

  • Warehouse Stock: 50 units in Rotterdam

  • Express Support: Weekly 100-unit top-ups from Shenzhen

  • Advantage: Quick adaptation to market response

Model 3: Multi-Warehouse Balancing Model

• Application: Sellers operating in multiple regional markets

• Warehouse Role: Regional inventory optimization

• Express Role: Cross-warehouse transfer and urgent fulfillment

• Example:

  • Scenario: East Coast warehouse stockout, West Coast has surplus

  • Solution: Express transfer between warehouses (2-3 days)

  • Alternative: Direct express from China to customer (7-10 days)
