Transit times from China to the U.S. West Coast and China to the U.S. East Coast both experienced modest increases, while the route from China to North Europe saw a notable reduction in transit time.

Welcome to the new Ocean Timeliness Indicator! Due to ongoing global shipping events in the Panama and Suez Canal, we have refined our previous report by splitting the Transpacific Eastbound (TPEB) trade lane into two subtradelanes: TPEB to the U.S. West Coast, and TPEB to the U.S. East Coast.

Week to September 8, 2025

Transit time from China to the U.S. West Coast increased by 0.5 days, rising from 32.4 to 32.9 days. The China to U.S. East Coast route saw a 0.8-day increase, moving from 64.3 to 65.1 days. Lastly, transit time from China to North Europe decreased by 3 days, falling from 62.5 to 59.5 days.

The Methodology: The Flexport Ocean Timeliness Indicator (OTI) utilizes data from Flexport’s ocean shipping operations for an expansive view of the cargo’s journey. Updated on a weekly basis, the Flexport OTI shows the transit time from the cargo ready date at the exporters’ factory or warehouse to the containers’ departure from the destination ocean port. The ocean shipping world tends to run along “trade lanes.” The three biggest east-west trade lanes carry goods from Asia to the U.S. West Coast, Asia to the U.S. East Coast, and from Asia to Northern Europe. The OTI captures the timeliness of each. As there are many transit time nuances from port to port and service to service, to show accurate trends, the OTI uses the following logic:

• Excludes premium services.
• Displayed transit times are based on a trailing two-week median.
• Major origin and destination ports are used as a proxy for the overall trade lane to create clear trends. Other origin or destination ports will have additional transit time considerations based on ocean carrier services.
• Asia to U.S. West Coast trade lane uses the China ports of Shanghai and Ningbo and the U.S. West Coast ports of Los Angeles/Long Beach.
• Asia to U.S. East Coast trade lane uses the China ports of Shanghai and Ningbo and the U.S. East Coast ports of New York/New Jersey and Norfolk.
• Asia to North Europe trade lane uses the China ports of Shanghai and Ningbo and the North Europe port of Rotterdam.
