In October 2020, the Federal Maritime Commission gave CMA CGM breathing room on tariff and contract filing after a ransomware attack knocked out its systems.
This post is a look back at a narrow but telling regulatory moment from October 2020. It won't affect a shipment you're booking today, but it's a useful reminder of how much of international ocean freight runs on paperwork filed with a federal agency most shippers never think about — and what happens when a carrier suddenly can't file it.
A Ransomware Attack Knocked CMA CGM Offline
In late September 2020, CMA CGM — one of the world's largest ocean carriers — was hit by a ransomware attack (later attributed to the Ragnar Locker group) that forced the company to shut down external access to its IT systems to contain the damage. Booking platforms, websites, and internal applications across CMA CGM's network went dark for days while the company worked to isolate the malware.
Among the systems affected were the ones CMA CGM used to meet its obligations under the U.S. Shipping Act: publishing its tariffs (the published rates and rules that govern how it charges for cargo) and filing service contracts with the Federal Maritime Commission (FMC). Ocean common carriers serving U.S. trade are legally required to keep these on file and up to date — it's part of how the FMC keeps freight pricing and contract terms transparent and enforceable.
What the FMC Actually Granted
On October 7, 2020, CMA CGM and its corporate affiliates petitioned the FMC for temporary exemption from those filing requirements, explaining that the cyberattack had made timely compliance impossible. The Commission granted the request on October 20, 2020, giving CMA CGM relief from certain tariff publication and service contract filing deadlines while it rebuilt its systems.
The relief had real limits, which is worth noting because it shows how narrowly the FMC exercises this kind of authority:
- The exemption from tariff publishing rules applied only prospectively — to cargo received on or after the date of the order — not retroactively to cargo already moving.
- The FMC does not have authority to grant retroactive relief, so CMA CGM had to rely on separate Shipping Act procedures to address freight charges tied to cargo it moved before the order was issued.
- The temporary exemption was time-limited and expired in late November 2020, once CMA CGM's filing systems were back online.
Why This Kind of Ruling Matters to Shippers
Most importers and exporters never read an FMC order and don't need to. But rulings like this one are a reminder that ocean freight pricing isn't just a quoted number — it sits on top of a regulatory structure of published tariffs, filed service contracts, and carrier compliance obligations. When that structure gets disrupted, even briefly, it can ripple into booking availability, rate transparency, and how disputes over charges get resolved.
Five years on, the specific 2020 exemption is long expired, but the underlying dynamic hasn't changed: carrier-side disruptions — whether a cyberattack, a port congestion event, or a rate filing dispute — can affect cost and timing on an international shipping move in ways that have nothing to do with your own freight. That's exactly the kind of complexity a good logistics partner is built to absorb.
How LVC Handles That Complexity
For crates leaving Las Vegas on an international routing, we build in ISPM-15 compliant wood packaging, coordinate the customs documentation and carrier-side paperwork the move requires, and work with freight forwarders to keep a shipment moving even when something upstream — a filing hiccup, a schedule change, a regulatory update — gets in the way. If you're weighing whether to route a shipment through a freight forwarder or a customs broker, or just want a straight answer on what an international crate-and-ship job will actually cost, get a quote and we'll walk you through it.
