Analyzed Economic Effects
4 provisions identified: 0 benefits, 4 costs, 0 mixed.
Alleged Improper Demurrage/Dwell Fees
Complainants say Zim and the Port of Houston charged demurrage and “dwell” fees while the complainants could not move their containers due to circumstances beyond their control. This complaint is filed with the Federal Maritime Commission and the case is scheduled for an initial decision by May 26, 2027 and a final Commission decision by December 10, 2027.
Alleged Fees Charged Without Proper Invoices
Complainants allege Respondents charged fees without issuing proper invoices as required. If true, that practice could affect businesses that receive and dispute shipping charges at the Port of Houston.
Alleged Failure To Publish Separate Rates
Complainants allege Respondents failed to publish separate demurrage rates for unique container types. That practice is raised in the complaint filed with the Federal Maritime Commission and could affect shippers seeking clear published rates.
Alleged Retaliatory Lawsuits Filed
The complaint alleges that Respondents filed two retaliatory lawsuits in United States District Court against the complainants. The complaint asserts this conduct as part of the dispute before the Federal Maritime Commission.
