Core Viewpoint - The article analyzes the differences between international air freight and sea freight, highlighting their unique advantages and applicable scenarios, which significantly impact supply chain efficiency and cost control in global trade [2][8]. Group 1: Transportation Speed - Air freight is characterized by its remarkable speed, typically taking 3-5 days for shipments from China to the U.S. West Coast, making it ideal for time-sensitive products like electronics and fashion items [2][8]. - In contrast, sea freight is slower, requiring approximately 13-18 days to the U.S. West Coast and 25-35 days to the East Coast, which is acceptable for less time-sensitive goods like daily necessities and construction materials [2][8]. Group 2: Transportation Cost - Air freight costs range from 30 to 80 RMB per kilogram, influenced by weight, volume, and flight schedules, making it expensive [2][8]. - Sea freight is more economical, with costs for a 20-foot standard container from China to the U.S. West Coast ranging from 1,500 to 3,000 USD, translating to as low as a few RMB per kilogram, suitable for heavy and bulky items [2][8]. Group 3: Transportation Capacity - Air freight has limited cargo capacity, typically accommodating tens of tons, making it suitable for smaller and lighter goods [3][4]. - Sea freight offers vast capacity, with large container ships able to carry thousands of standard containers, ideal for oversized machinery, vehicles, and bulk commodities [4][8]. Group 4: Transportation Risks - Air freight is less affected by weather and has lower risks of theft and damage, but delays can be complex and costly [4][8]. - Sea freight, while generally stable, faces risks from adverse weather and piracy, but advancements in maritime technology and insurance have mitigated these risks [4][8]. Group 5: Operational Processes - Air freight has a simpler and more efficient operational process, with customs clearance completed in 2-3 days if documentation is complete [6][8]. - Sea freight involves a more complex process with multiple steps, potentially taking 5-7 days or longer for customs clearance [6][8]. Group 6: Selection Strategy - For high-value goods, urgent items, or small and light shipments, air freight is recommended due to its speed despite higher costs [7][8]. - Sea freight is preferable for large, heavy shipments, non-urgent goods, and strict cost control, leveraging its capacity and lower costs [7][8].
