FMC detention demurrage rule 2026: what the 541.4 vacatur means for NVOCCs

The FMC detention demurrage rule 2026 landscape is half what the agency wrote in 2024 and half what the D.C. Circuit took back in 2025. Per the FMC's own statement on the September 23, 2025 ruling in World Shipping Council v. FMC, the court vacated 46 C.F.R. 541.4—the section that restricted who could be invoiced—while leaving the rest of Part 541 intact, including the 30-day invoice deadline and content requirements.

What the 541.4 vacatur removed

Section 541.4 had limited D&D invoices to two categories: the party that contracted with the billing party for ocean transportation or storage, and the consignee. Jones Walker's analysis walks through how the court found the FMC's reasoning—particularly its handling of motor carriers in the May 2024 correction—"internally contradictory and thus arbitrary and capricious." The vacatur removes the bright-line restriction. Carriers can again pursue motor carriers, freight forwarders, and other parties they would have been blocked from invoicing under the rule as written.

OSRA 2022 invoice 30-day window survived

The 30-day invoice deadline is still binding. Per the FMC's final rule notice, VOCCs and MTOs must issue D&D invoices within 30 calendar days of when charges were last incurred. NVOCCs have a separate 30-day window measured from the issuance date of the invoice they received. Miss either window and the obligation to pay the charge is eliminated. The dispute mechanism also survived: billed parties have 30 days to request mitigation, refunds, or waivers, and billing parties have 30 days to resolve.

NVOCC billing reshuffle and D&D dispute timeline

The combination is uncomfortable for NVOCCs. They lost the protection that limited who could be billed upstream, but the 30-day clock to invoice their customers downstream still runs from the moment they receive a VOCC invoice. If a VOCC turns around and bills a motor carrier, freight forwarder, or BCO directly under the post-vacatur framework, the NVOCC may find itself outside the dispute loop on charges its customers ultimately owe. The defensive posture: tighten contracts to require pass-through invoicing through the NVOCC, document chain-of-custody on every container, and timestamp every invoice receipt to preserve the 30-day window.

How freight teams should position

Three plays. One: audit your D&D invoice intake process. Anything older than 30 days from charge incurrence is presumptively unpayable; build the rejection workflow into AP. Two: revisit master service agreements. Post-541.4, contractual billing-party language carries more weight because the regulatory floor is gone. Three: track dispute outcomes with bill of lading search tied back to terminal-event timestamps. With both sides on 30-day clocks, a documented dispute log is the cheapest way to recover charges that should have been waived but were processed on autopilot.

Freight forwarders and NVOCCs running tight D&D defense programs need a clean line of sight into container movements, terminal events, and invoice timing. Logistic Intel's freight forwarders solution surfaces shipment-level history and counterparty patterns that make 30-day invoice and dispute timelines defensible against carrier counter-claims.
