Transpacific rates remain near July highs, the Panama Canal is cutting slots in September, global port congestion has climbed to 4.3 million TEU above the 2022 peak, carriers are cautiously returning to the Red Sea, new 50% tariffs on about $20 billion of Canadian exports took effect August 19 with retaliation planned for September 8, the Jones Act waiver now runs through November 15, FMC invoice liability rules are in force, and DOT/CVSA brake-check blitzes are raising roadside risk. For shippers, that means tighter booking discipline, stronger compliance, and better visibility across logistics, fulfillment, and inventory management for ecommerce.
Why are rates and routing still under pressure?
Asia–U.S. spot rates are still elevated at roughly:
$7,600/FEU to the U.S. West Coast
$9,000–$10,000/FEU to the U.S. East Coast
Extra surcharges on Panama-dependent services
The Panama Canal’s July operations summary supports the backdrop: transit capacity falls to 34 slots on September 3 and 32 on September 15. Congestion around Shanghai and Ningbo, plus selective Red Sea re-entry by carriers, is keeping schedules fragile and effective capacity tight.

What legal and cost changes matter most now?
The White House fact sheet confirms the new Canada tariffs; Canada plans retaliation on September 8. The Jones Act waiver guidance confirms the extension to November 15, but the HTS list is narrowed to 237 codes and each move now requires a pre-voyage Vessel Availability Request.
The FMC’s final-rule summary makes invoice liability specific: if required billing details are missing, the payment obligation can be eliminated. At the same time, the CVSA Operation Airbrake guidance and 2026 International Roadcheck reinforce brake-system enforcement during August safety blitzes.
What should shippers do next?
Third party logistics providers, supply chain management companies, and importers should audit tariff exposure, verify Jones Act eligibility, challenge weak demurrage and detention invoices, and confirm carrier routing assumptions. A modern warehouse management system, logistics software, and disciplined 3PL fulfillment services matter more when cargo arrives unevenly.
Lanta Logistics supports Mid-Atlantic fulfillment, 3PL Maryland operations, food-grade warehouse needs, Hazmat certified 3PL requirements, and Glen Burnie warehouse execution, with FlowOps by Lanta adding real-time visibility; contact Lanta Logistics to reduce avoidable supply chain cost.
