When you’re developing a plan for shipping goods from Asia to the USA, it’s critical to understand international transit times to support your supply chain strategy. Ocean and air freight transit times can vary widely depending on the point of origin and destination. With this knowledge, you can also develop contingency plans to address disruptions and delays and ensure timely deliveries.
Dimerco has developed this guide to international freight transit times for ocean and air freight from Asia to the USA, including China, Southeast Asia, India, Korea, Taiwan, and Vietnam.
Keep in mind the typical transit times vary by lane and are usually expressed as port‑to‑port (ocean) or airport‑to‑airport (air), not including origin/destination handling or customs.
For planning purposes, many shippers use a baseline estimate of 20–45 days for ocean and 1–10 days for air on long‑haul international lanes, then refine by origin, destination, and carrier schedule.
Here’s a more granular view of the ocean and air freight transit times broken down by origin and destination.
Ocean Freight Transit Times (Asia to USA)
These are typical port‑to‑port ranges for full container loads in normal conditions. Actual schedules vary by carrier, season, and congestion situations.
As a rough rule of thumb, Asia–North America West Coast services cluster around 20–30 days, and Asia–North America East/Gulf services around 30–45 days port‑to‑port.
| Origin region/country | To U.S. West Coast (LA/LB, Seattle, Oakland) | To U.S. East & Gulf Coasts (NY/NJ, Savannah, Houston) |
| China (major ports: Shanghai, Shenzhen, Ningbo, Qingdao) | 15–25 days (e.g., Shanghai–LA around 15–20 days, Shenzhen–LA 18–22 days). | 30–45 days via Panama Canal or around South America; Ningbo–New York often 30–35 days. |
| South Korea (Busan) | 12–20 days to West Coast, depending on direct vs transshipment services. | 28–40 days, typically via Panama Canal; similar to North Asia–East Coast averages. |
| Taiwan (Kaohsiung, Taipei) | 14–22 days to West Coast on mainline services. | 30–42 days to East/Gulf Coasts with canal transit. |
| Vietnam (Ho Chi Minh City, Haiphong) | 20–30 days to West Coast; extra time often added for feeder legs. | 32–45 days to East/Gulf Coasts via transshipment hubs. |
| Southeast Asia (Singapore, Malaysia, Thailand, Indonesia) | 20–30 days to West Coast; Singapore–US West sits near the lower end when on direct strings. | 30–45 days to East/Gulf Coasts, depending on hub routing. |
| India (Nhava Sheva/Mumbai, Chennai) | 25–35 days to West Coast via transshipment (often through the Middle East or Singapore). | 30–45 days to East/Gulf Coasts, with some services closer to 30–35 days via Suez and Mediterranean/Europe hubs. |
Dimerco’s network typically moves freight in 15–22 days for major South/East China ports to the US West Coast and 30–40+ days for East/Gulf Coast destinations.
Air Freight Transit Times (Asia to USA)
Air freight times are airport‑to‑airport for standard services; door‑to‑door is usually 1–3 days longer for pickup, export clearance, and final delivery.
| Origin region/country | Typical air freight time to major U.S. gateways (LAX, SFO, ORD, JFK) |
| China | 1–5 days for standard airport‑to‑airport; Shanghai–LA flight time 12–14 hours, with total transit usually 3–5 days, including clearance and ground handling. |
| South Korea (Seoul) | 1–4 days on frequent direct services to West Coast and Chicago. |
| Taiwan (Taipei) | 1–4 days to West Coast and 2–5 days to East Coast, depending on routing and space. |
| Vietnam (Ho Chi Minh City, Hanoi) | 2–5 days; often 1–2 days longer than North Asia because of fewer direct wide‑body flights. |
| Southeast Asia (Singapore, Malaysia, Thailand, Indonesia) | 2–6 days, depending on whether freight moves on direct or connecting flights into U.S. hubs. |
| India (Delhi, Mumbai, Bangalore, Chennai) | 3–7 days, reflecting longer distances and reliance on one‑stop routings via Europe or the Middle East for many services. |
Dimerco’s network typically moves China‑to‑US air cargo in 1–3 days on direct flights and 3–5 days on indirect routes, with door‑to‑door delivery of 5–8 days.

Select the Best Mode for Transit Time and Rates
One of the primary uses for this guide to Asia-USA freight transit times is selecting air, ocean or hybrid service as the optimal mode to provide the level of service you need at rates that make sense for your bottom line.
Air Freight: The default option for high-value, time-sensitive products like semiconductors and pharmaceuticals that need to reach their destination within a few days. The cost of transport is only a small factor in the overall profit margin for these products. To optimize your air freight strategy and reduce spend, get our eBook on how to Reduce International Air Freight Costs.
Ocean Freight: In this mode, the tradeoff is speed vs. costs. Shipping times are measured in days and weeks, not hours. The total duration depends greatly on the origin and destination, as well as whether the shipment is full container load (FCL) or less than container load (LCL).
Combined Ocean and Air: Fine-tune transit time and costs with a hybrid of ocean and air freight. Typically, goods move by water from a location without convenient air service to an airport for the final leg. Costs are lower than full air freight, and lead times are shorter than full ocean moves. This is a cost-effective option when the product value or timeline doesn’t support premium air freight services.
Why Shipping Times May Vary
If your shipment is not on time, it may be due to factors other than the actual transit time. Other considerations may arise between pickup and delivery that cause delays when shipping from Asia to the USA.
Customs Clearance: Customs delays can add days to the total timeline, so ensure that documentation is complete and accurate. Work with an experienced freight forwarder to minimize potential delays and additional costs.
Congestion: Ports and airports can be backed up due to weather events, seasonal demand, or external factors such as strikes or work stoppages. Connect with your logistics provider to stay up to date on conditions and anticipate potential delivery delays.
Seasonality: Look ahead on the calendar to anticipate potential delays from increased demand, such as holiday inventory stocking or slowdowns as workers take time off.
Dimerco can help plan for the inevitable external issues that could extend your total transit time.
