Freight Pulse & Law Update: Panama Capacity Tightens as CBP Maps the Next Import Rulebook
September 3, 2026 | 13:00 ET
Importers face a four-part squeeze: tighter Panama Canal capacity, German port strikes, Typhoon Saudel disruptions in China, and a new CBP proposal that could significantly expand supply-chain data expectations.
What is CBP proposing?
On September 2, CBP published an advance notice of proposed rulemaking (ANPRM) titled “Heightened Import Disclosures for Supply Chain Visibility”, Docket USCBP-2026-1058.
CBP is considering:
Foreign export documentation submitted to overseas customs authorities
More detailed identification of manufacturers, shippers, exporters, sellers, and other parties
Global business identifiers, including D-U-N-S, GLN, LEI, or Altana ID
Technology-supported supply-chain tracing and stronger data integrity
This is not a final rule. No new mandate from this ANPRM is effective today. CBP is accepting comments through December 1, 2026, and responses may inform a future notice of proposed rulemaking.
Why is freight risk rising now?
The Panama Canal reduced daily transits to 34 on September 3 and plans to cut capacity to 32 from September 15. Reservations matter more as available passage tightens.
In Europe, a 48-hour warning strike is affecting Hamburg, Bremerhaven, Wilhelmshaven, Bremen, Brake, and Emden. Trans.info reports that Eurogate rail slots are blocked for September 4, extending disruption beyond the terminals.
Meanwhile, Linerlytica reporting cited by Safety4Sea places 3.92 million TEU, or 11.4% of the global container fleet, at anchorages amid Typhoon Saudel disruptions.
What should importers do now?
Audit foreign export documents, party records, and identifier accuracy.
Ask third party logistics providers and customs brokers which data they can retrieve and retain.
Connect your warehouse management system and logistics software to shipment and inventory records.
Review inventory management for ecommerce, reorder points, and safety stock.
Reserve Panama capacity early and price alternate routings.
Keep domestic carriers ready for normal DOT/FMCSA brake-check and safety-blitz expectations.
