- Basic comparison of transportation methods
Comparison dimensions Air freight Sea freight
Transportation time 1-7 days 15-45 days
Transportation cost High (charged by weight/volume) Low (charged by container)
Carrying capacity Limited (usually <100 tons) Large (up to tens of thousands of tons)
Applicable distance Medium and long distance is the best Ultra-long distance has the most advantages
Flexibility High (more flights) Low (fixed shipping schedule) - Choose solutions based on the characteristics of goods
- Give priority to goods shipped by air
High-value goods: jewelry, luxury goods, precision instruments (reduce capital occupation and risk)
Time-sensitive goods: fresh food, emergency medicines, fashion apparel (strong seasonality)
Light and small goods: electronic products, samples, documents (air freight costs are relatively acceptable)
Fragile goods: glass products, high-precision equipment (reduce the number of handling times)
- Commodities shipped by sea are preferred
Large low-value commodities: ore, grain, building materials (cost-sensitive)
Heavy and large items: machinery and equipment, vehicles, industrial raw materials (too large volume/weight)
Non-time-sensitive commodities: furniture, daily necessities, general chemicals
Liquid/bulk cargo: oil, chemicals (special container transportation)
III. Considerations for mixed strategies
Sea-air transport: high-value + medium-time-sensitive commodities (such as auto parts)
Seasonal adjustment: sea transport stocking before peak season + air transport replenishment during peak season
Inventory strategy: basic sea transport inventory + air transport emergency replenishment
IV. Decision-making flow chart
text
Start
↓
Is the commodity perishable/time-sensitive? → Yes → Choose air transport
↓No
Is the value/weight ratio of the commodity high? → Yes → Consider air transport
↓No
Is the volume of the cargo >2m³ or the weight >500kg? → Yes → Choose sea transport
↓No
Is the transportation cost a key factor? → Yes → Choose sea transport
↓No
Evaluate other special needs → Customize solutions
V. Special considerations
Prohibited items: lithium batteries (air transport restrictions), dangerous goods (special requirements for sea transport)
Customs clearance efficiency: air ports usually handle faster
Insurance costs: air transport premiums for high-value goods may be lower (short risk period)
Environmental considerations: The carbon footprint of sea transport is only 1/50 of that of air transport
Enterprises should conduct a comprehensive assessment based on product characteristics, market demand and cost structure, and adopt a logistics combination strategy to maximize benefits when necessary.
