How to Avoid the Biggest Detention & Demurrage Pitfalls: Today's 15:00 Law Update

The Federal Maritime Commission (FMC) isn't just watching anymore: they are swinging the gavel. As of July 2026, the 30-day "drop dead" rule for invoicing is the industry’s biggest profit-killer if you aren't paying attention.

The 30-Day Hard Wall

The core of today’s 15:00 law update is the FMC’s aggressive stance on 46 CFR 541.7(a). Carriers and MTOs must issue detention and demurrage (D&D) invoices within 30 days of the charges being incurred. If they miss that window by even 24 hours, the invoice is effectively void. We saw this play out in March 2026 when the FMC targeted Hapag-Lloyd for $1.19 million in re-issued, non-compliant invoices. For shippers, this is your primary shield: if the clock runs out, the bill is dead.

The 2025 Court Pivot

While the 30-day rule is a "bright-line" compliance issue, the "who gets billed" debate is currently in a state of flux. Following the September 2025 D.C. Circuit Court decision, parts of the rule restricting who carriers can bill: specifically motor carriers: were vacated. This means your 3PL Maryland partner must be more vigilant than ever about contract language and liability shifts. You need a partner that understands how to challenge inaccurate free-time calculations before they hit your bottom line.
