Advisories

The United States Supreme Court issued three new rulings today, but did not rule on the legality of President Donald Trump’s tariffs, which were used as part of the International Emergency Economic Powers Act (IEEPA).

• If the U.S. Supreme Court decides that Trump’s IEEPA tariffs are illegal, companies may be eligible for refund payments, which would likely total tens of billions of dollars.

Starting Feb. 6, 2026, U.S. Customs and Border Protection (CBP) will issue all refunds electronically via Automated Clearing House (ACH), as announced in the Electronic Refunds Interim Final Rule published in the Federal Register. Refunds will only be issued electronically; checks will no longer be mailed, and importers without a proper ACH Refund Account will not be able to receive their refunds. 

The ACE Portal is a centralized platform that connects the trade community with CBP and partner government agencies, providing real-time access to trade transactions and data. The enhanced ACE portal enables secure electronic refunds, faster payments, fewer errors, and creates a simplified process for importers, brokers, and refund recipients.

Yemen’s Houthi rebels signaled a halt to their attacks on commercial ships in the Red Sea following the tenuous ceasefire between Gaza and Israel. Officials at major shipping lines are actively discussing a return to the shipping lane, with some regional carriers already acting, but the future is still very uncertain.

“We are closely monitoring developments and declare that if the enemy resumes its aggression against Gaza, we will return to our military operations deep inside the Zionist entity [Israel], and we will reinstate the ban on Israeli navigation in the Red and Arabian Seas.” – Yusuf Hassan al-Madani, Houthi Armed Forces’ Chief of Staff

• The Houthis did observe a ceasefire at the start of 2025, but when hostilities resumed in Gaza, the Houthis also resumed their activities.
• CMA CGM and Maersk are both preparing for a return next month. “Given the significant progress on both fronts, Maersk will take steps to resume navigation and, over time normalize the transits on this route,” the company stated.

Ship movements that once relied on Automatic Identification System (AIS) broadcasts and port reports can now be observed visually, continuously, and without a vessel’s cooperation via satellites—a quiet technological revolution that could greatly impact maritime operations. Enhanced Electro-Optical (EO) satellite imagery, long associated with military intelligence and environmental monitoring, has rapidly matured into a commercially accessible, high-resolution tool.
