International shipping time is not a fixed value. It is affected by multiple factors, including route distance, transportation method, and logistics efficiency. Approximate shipping times also vary significantly across regions.
In this article, Weefreight will provide a detailed explanation from the perspectives of “influencing factors” and “typical shipping times.” We hope this will be helpful.
- Core Factors Influencing International Shipping Time
Route Distance and Port Location
Route distance is the fundamental factor determining shipping time: transoceanic routes (such as China to Europe and the United States) naturally have longer sailing times due to their distance; whereas intra-regional routes (such as China to Southeast Asia) generally have shorter shipping times due to their shorter distances. Port location also affects overall transit time. If the port of departure/destination is a “basic port” (such as Shanghai and Shenzhen Yantian in China, or Los Angeles and Long Beach in the United States), shipping companies offer frequent sailings and frequent calls (typically one to two sailings per week), enabling fast transit times. If it is a “non-basic port” (such as Zhanjiang in China or Portland in the United States), the vessel must first call at a basic port before transshipping, adding an additional 3-7 days to transit time.
Ship Speed and Sailing Schedules
Ship speeds vary significantly between different types of ships: Standard container ships travel at approximately 18-22 knots (1 knot = 1.852 km/h), while fast container ships (mostly used for time-sensitive cargo) can reach speeds of over 25 knots, shortening transoceanic voyages by 1-3 days. Furthermore, shipping company schedules can also affect delivery time. If cargo can be shipped on a direct vessel (without stopping at other ports), delivery time will be significantly faster than on a transshipment vessel. However, if a vessel is delayed (e.g., due to ship maintenance or weather cancellations), delivery time will be extended.
Port Operation Efficiency
Loading, unloading, and customs clearance efficiency at both the port of departure and the port of destination directly impact delivery time:
Port of Departure: If cargo arrives at the port with adequate terminal loading and unloading equipment, efficient tallying, and complete customs declaration documentation (no document issues), loading can typically be completed within 1-2 days. However, if the port is congested (e.g., during peak season when containers are overstocked at Shanghai and Los Angeles ports), loading and unloading times may extend to 3-5 days, or even longer.
Destination Port: After cargo arrives at the port, it must undergo unloading, terminal storage, customs clearance, and pickup. If the customs clearance process at the destination port is complex (e.g., strict customs inspections in some South American and Middle Eastern countries) or the terminal is understaffed, pickup may be delayed by 3-10 days.
Cargo Types and Transportation Requirements
General Cargo: If cargo does not require special handling (e.g., refrigerated cargo or hazardous goods), it can be quickly assigned to regular shipping space, and delivery times are relatively stable.
Special Cargo: Refrigerated cargo (e.g., fresh produce, pharmaceuticals) requires refrigerated containers. If refrigerated space is limited on a vessel, a specific sailing date may be required. Dangerous goods (e.g., flammable liquids, corrosive cargo) must comply with the safety regulations of the shipping company and the port, resulting in more complex customs clearance and loading procedures, and delivery times may be 2-5 days longer than for general cargo.
Oversized/Overweight Cargo: Special lifting equipment (e.g., gantry cranes, floating cranes) is required. If the port of departure/destination lacks the necessary equipment, transit to a qualified port may be necessary, which will incur additional delivery costs.
Seasonal and Weather Factors
Peak Season Impact: During the annual “peak shipping season” (e.g., the two to three months before the Chinese New Year and the Christmas season in Europe and the United States), shipping space is tight and cargo is piling up at ports. This can extend vessel docking and loading and unloading times, resulting in overall shipping times that are 5-10 days slower than the off-season.
Weather Impact: Transoceanic routes (e.g., the North Atlantic and North Pacific) are prone to severe weather such as typhoons, blizzards, and high waves in winter. Vessels may need to detour or dock for shelter, increasing shipping times by 3-7 days. However, routes to Southeast Asia and Australia and New Zealand enjoy relatively stable weather year-round, so weather has a lesser impact on shipping times.
II. Approximate Time Flows for Different Routes (Based on Major Chinese Ports as the Port of Departure)
International ocean shipping times are typically calculated in calendar days, encompassing loading at the port of departure, sea voyage, unloading at the port of destination, and customs clearance (excluding inland transportation from the port of destination to the final warehouse). The following are reference times for common routes (assuming off-season and direct shipping):
China to Southeast Asia Routes
These routes cover ports such as Singapore, Malaysia (Port Klang), Thailand (Laem Chabang Port), and Vietnam (Ho Chi Minh Port). These routes are short (approximately 1,500-3,000 kilometers) and take only 3-7 days to sail. Including loading at the port of departure and customs clearance at the port of destination, the overall time is typically 7-12 days.
China → East Asia / Japan and South Korea Route
To South Korea (Pusan Port, Incheon Port): Sailing time 1-3 days, overall transit time 3-7 days; To Japan (Tokyo Port, Yokohama Port, Osaka Port): Sailing time 2-4 days, overall transit time 5-9 days (if arriving at a Japanese port such as Sapporo, transit time will increase by 2-3 days).
China → Australia and New Zealand Route
To Australia (Sydney Port, Melbourne Port): Sailing time 8-12 days, overall transit time 12-18 days; To New Zealand (Auckland Port): Sailing time 11-15 days, overall transit time 15-22 days (During the typhoon season during the Southern Hemisphere summer (December-February), transit time may increase by 2-3 days).
China → Europe Routes
To key European ports (such as Rotterdam in the Netherlands, Hamburg in Germany, and Felixstowe in the UK): Direct shipping takes approximately 28-35 days, with a total transit time of 35-45 days. Transit via Singapore or Dubai increases transit time by 7-10 days.
To Mediterranean ports (such as Genoa in Italy and Barcelona in Spain): Direct shipping takes 32-40 days, with a total transit time of 40-50 days.
China → US West Coast/East Coast Routes
US West Coast Routes (to the Ports of Los Angeles and Long Beach): Direct sailing time is 12-18 days, with an overall delivery time of 18-25 days. (Note: West Coast ports are prone to congestion during peak season (August-November), which may extend delivery times by 5-10 days.)
US East Coast Routes (to the Ports of New York and Savannah): There are two routes: full ocean shipping (via the Panama Canal), with a sailing time of 25-32 days and an overall delivery time of 32-40 days. The other is combined sea-rail transport (first shipping to a US West Coast port, then transferring to a rail route to the US East Coast). This approach offers similar delivery times to full ocean shipping, but may also offer lower costs.
China to South America Routes
To the east coast of South America (e.g., Santos Port, Brazil, Buenos Aires Port, Argentina): Direct sailing time is 35-45 days, with a total transit time of 42-55 days (customs clearance efficiency at some South American ports is lower, which may add an additional 5-8 days). To the west coast of South America (e.g., San Antonio Port, Chile): Sailing time is 28-35 days, with a total transit time of 35-45 days.
China → Middle East/Africa Routes
Middle East Routes (to Dubai, UAE, and Jeddah, Saudi Arabia): Direct sailing time is 15-22 days, with an overall transit time of 22-30 days.
Africa Routes: To North Africa (e.g., Alexandria, Egypt), sailing time is 25-32 days, with an overall transit time of 32-40 days; to South Africa (e.g., Durban), sailing time is 28-35 days, with an overall transit time of 35-45 days; to East Africa (e.g., Mombasa, Kenya), sailing time is 22-28 days, with an overall transit time of 28-38 days.
Note: The above transit times are “reference values” only. Actual transit times may vary depending on the specific port, shipping company, season, and cargo availability. We recommend confirming the latest sailing schedule and transit time estimates with your freight forwarder before shipment.
