Panama Canal Draft Limits Trigger New Carrier Surcharges
Ocean carriers have begun adding hundreds of dollars per container to Asia–US East and Gulf Coast bookings, and the reason sits several thousand miles from either coast. Falling water levels in Gatun Lake have prompted the Panama Canal Authority (ACP) to tighten Panama Canal draft limits through the summer, and the cost of that decision is now arriving on shippers’ invoices.
What the Canal Has Actually Restricted
The ACP has moved in measured steps rather than one dramatic cut. Maximum authorized draft at the Neopanamax Locks was lowered to 49.5 feet in early July, reduced again to 49 feet on July 24, and is scheduled to drop to 48.5 feet on August 15. The authority has been explicit that these are precautionary water management measures, and that further adjustments depend on rainfall and lake projections in the weeks ahead.
The driver is meteorological. Forecasters have raised the probability of a significant El Niño event sharply since spring, and the ACP has signaled that if conditions worsen, restrictions could extend beyond draft to the number of daily booking slots — the mechanism that caused the most disruption during the last drought.
Why Half a Foot Costs Hundreds of Dollars
Draft is a proxy for weight. Every inch a vessel cannot sit lower in the water represents cargo that must come off, be transshipped, or be routed another way. A large container ship gives up meaningful capacity for each incremental reduction, and the fixed cost of the voyage does not fall with it. Carriers recover that gap through surcharges.
Those surcharges are now public. CMA CGM introduced a $320 per TEU charge on cargo moving to the US East and Gulf Coasts, effective July 25, with a lower charge applied to Central American and Caribbean destinations. Hapag-Lloyd has announced $130 per TEU on Far East–North America cargo transiting the canal from August 15. MSC has set $100 per TEU on Asia to US East and Gulf Coast shipments, applying to cargo gated in from August 19. Additional announcements are widely expected.
The spread between those figures is worth noting. Carriers are not working from a common formula, which means two shipments on comparable routings can carry materially different canal-related costs depending on the carrier contracted.
Context Matters: This Is Not 2023
During the last drought cycle, draft fell into the low 40s and daily transits were cut, producing queues, auction premiums, and schedule failures that rippled through peak season. The current restrictions are considerably milder, and the canal has reported strong transit volumes and revenue through the first nine months of its fiscal year.
That context should inform planning without inviting complacency. The risk is not today’s draft figure. It is the possibility of booking slot reductions later in the year, which would affect schedule reliability far more than cargo weight limits do.
Three practical steps apply to US and UK shippers alike.
Audit your exposure by carrier and lane. Surcharges vary widely, and the effective dates differ. Cargo gating in around mid-August may cross a threshold that cargo moving a week earlier does not.
Build the charge into landed cost, not just freight cost. For lower-value, high-volume goods, a few hundred dollars per container can change duty-inclusive margins and pricing decisions further downstream.
Review routing alternatives before you need them. US West Coast discharge with inland rail, Suez routings for certain origins, or adjusted sailing schedules all carry trade-offs in transit time and cost. Those comparisons are far more useful modeled in advance than negotiated under pressure.
Panama Canal draft limits are, for now, a cost issue rather than a capacity crisis. Whether that holds through the fall depends on rainfall the industry cannot control — which is precisely why the planning should happen now.
