Sea freight is a primary mode of global trade, with its costs and timeliness influenced by multiple factors. Below is an analysis of key influencing factors and a comparative table:

1. Cargo Attributes

  1. Weight and Volume

    • Shipping costs are typically calculated based on "weight tons" or "measurement tons" (1 cubic meter = 1 ton), taking the larger value. Heavy goods (e.g., machinery) are charged by weight, while light bulky goods (e.g., textiles) are charged by volume.


  2. Cargo Type and Hazard Level

    • General goods (e.g., furniture, electronics) have lower costs; hazardous materials (e.g., chemicals, lithium batteries) require special handling, incurring additional fees (e.g., dangerous goods surcharges) and stricter transportation restrictions.


  3. Packaging and Dimensions

    • Oversized items (e.g., machinery) or irregularly shaped cargo may require special containers (e.g., open-top or flat-rack containers), increasing costs.


2. Shipping Route and Ports

  1. Origin and Destination Ports

    • Popular routes (e.g., China to Europe) have stable freight rates due to frequent sailings; niche routes (e.g., minor ports in Africa) may require transshipment, leading to higher costs and longer transit times.


  2. Port Congestion and Efficiency

    • Congested ports (e.g., Los Angeles or Shanghai during peak seasons) cause vessel delays and higher demurrage fees, driving up overall costs.


  3. Bunker Adjustment Factor (BAF) and Currency Adjustment Factor (CAF)

    • Fuel price fluctuations directly affect BAF; exchange rate changes are reflected in CAF.


3. Container Type and Sailing Schedule

  1. Container Type

    • Standard containers (20GP/40GP) are used for general cargo; reefer containers (for fresh produce, pharmaceuticals) cost 30%-50% more; special containers (e.g., tank containers) are even more expensive.


  2. Sailing Speed and Schedule

    • Express services (e.g., Matson 快船) are faster but costlier; regular sailings are cheaper but slower.


  3. Booking Time and Space Availability

    • During peak seasons (e.g., before major shopping festivals), space is tight, requiring early booking and potentially increasing rates by 20%-50%.


4. Market Supply and Demand, and Additional Services

  1. Seasonal Demand

    • Freight rates rise by 20%-50% during peak seasons (e.g., before Christmas or Black Friday) and decline in off-seasons (e.g., summer).


  2. Additional Service Fees

    • Includes terminal handling charges (THC), documentation fees, customs clearance fees, and insurance, with significant variations across ports.


  3. Trade Terms (e.g., FOB, CIF)

    • Under FOB, the buyer pays freight; under CIF, the seller covers freight and insurance, impacting pricing strategies.


5. Policies and External Environment

  1. International Trade Policies

    • Tariffs, anti-dumping duties, or trade barriers may increase costs (e.g., higher freight rates for some goods during the U.S.-China trade war).


  2. Weather and Natural Disasters

    • Extreme weather (e.g., typhoons, tsunamis) can delay sailings or force route adjustments, incurring extra costs.


  3. Environmental Regulations (e.g., IMO 2020 Sulfur Regulations)

    • Compliant vessels must use low-sulfur fuel, increasing operational costs by 5%-10%, partially reflected in freight rates.
