October Import Volume Trends 

  • Over the past six years, import volume consistently increased from September to October due to the latter being one day longer and having no major holidays. 
  • This trend persisted in October 2023, with a substantial increase in import volume over September (see Figure 2).

Port Market Share 

  • Volume shares of top East and Gulf Coast ports increased, primarily driven by a significant volume surge at the Port of New York/New Jersey and growth at other leading East Coast ports. 
  • Comparing the top five East and Gulf Coast ports to the top five West Coast ports in October 2023 versus September 2023 reveals that, of the total import container volume, top East and Gulf Coast ports increased to 45.1% (up 3.0%), while top West Coast ports decreased to 39.6% (down 3.7%). 
  • Compared to smaller ports, the top 10 ports share in October 2023 slightly decreased to 84.8%, down 0.6% versus September 2023 (see Figure 6).

Port Transit Delays 

  • In October 2023, overall port transit delays receded, with most top West Coast ports experiencing reduced transit times versus September (see Figure 7). 
  • The top East and Gulf Coast ports stabilized, with Norfolk and Houston experiencing transit delay decreases. The Port of Seattle saw the most significant reduction (1.6 days), while the Port of New York/New Jersey had only a slight increase (0.1 days) compared to September.

Note: Descartes’ definition of port transit delay is the difference as measured in days between the Estimated Arrival Date, which is initially declared on the bill of lading, and the date when Descartes receives the CBP-processed bill of lading. 

Panama Canal Impact 

  • Despite the ongoing drought in Panama affecting ship passages, there is no apparent impact on U.S. container import volumes (see Figure 8). 
  • Gulf Coast ports experienced the highest container import volume in October 2023, with transit times decreasing for the Ports of Houston (-1.1 days), Mobile (-1.0 days), Tampa (-2.0 days), and New Orleans (-1.1 days).

Strategic Recommendations to help overcome global shipping challenges. 


  • Monitor the growth of COVID variants, especially in critical supply chain regions, as they continue to disrupt the global supply chain. 
  • Keep a close eye on ocean shipments and carrier performance as ETAs continue to be inconsistent. 
  • Stay informed about the Panama Canal situation as it has a continued impact on shipping capacity and may cause the rerouting of supply chains. 
  • Assess the effects of inflation and geopolitical conflicts on logistics costs, and ensure your trading partners are not sanctioned. 
  • Prioritize retention of existing supply chain resources, paying special attention to the well being of your drivers. Above wage increases, ensure you are reducing their stress and improving their quality of life. 


  • Reassess trade redirected away from West Coast ports, particularly for companies importing from Asia. 


  • Evaluate supplier and factory location density to reduce reliance on overburdened trade lanes and conflict-prone regions. 

As Descartes continues to provide insights through data analysis, these key developments and recommendations offer a strategic guide for navigating current and future global shipping challenges.
