Key Takeaways
- Record Golden Week capacity: Double sailings lifted Asia-US West Coast weekly capacity to 393,000 TEU. The normal holiday level is below 300,000 TEU.
- Bunching erased blank sailings: Typhoon congestion in Asia pushed Q3 sailings into October and November, which swamped carriers’ blank sailing programs.
- Clustered US arrivals: Expect bunched discharges at LA/Long Beach and East Coast gateways. That creates dwell, demurrage, and detention risk.
- Softer spot leverage: Surplus capacity lets you negotiate rates in the short term, but schedule reliability is still poor.
Immediate Shipper Alert: Double Sailings Offset Golden Week Blanks
Typhoon-driven vessel bunching in Asia produced record Golden Week capacity instead of the usual seasonal dip. Plan for clustered arrivals at US gateways and rising demurrage exposure through November.
Blanks erased by bunching. A run of typhoons congested Asian loading ports and bunched vessels into “double sailings.” These canceled out carriers’ Golden Week blank sailing programs. Sea-Intelligence found that deployed capacity on the transpacific and Asia-Europe trades hit record-high Golden Week levels [1].
How a double sailing forms. Liner services run one departure a week from origin. When a vessel slips from week 1 to week 2, it sails alongside the original week 2 ship. Q3 departures cascaded into the October and November loading windows, and double sailings hit historically high levels on all four major trades Sea-Intelligence tracks [1].
West Coast sets a record. Sea-Intelligence measured Golden Week across weeks 40 to 42 to capture the inland lag while drivers are on holiday [1]. Asia-US West Coast weekly deployed capacity reached 393,000 TEU, above the normal Golden Week level of below 300,000 TEU [1]. That’s 4% above the rest of Q3, where the 2012 to 2019 average was an 8% holiday cut.
East Coast takes more. Asia-US East Coast capacity ran 15% above the rest of Q3, compared with a 2012 to 2019 Golden Week average reduction of 6% [1]. Asia-Mediterranean rose 18%, and Asia-North Europe rose 4%, so this isn’t a transpacific quirk [1].
Not a strategy change. Sea-Intelligence says carriers haven’t necessarily abandoned seasonal capacity management. In its view, bunched vessels inflate active weekly sailings and mathematically suppress the blanked-capacity percentage [1]. Don’t treat this surplus as a new baseline.
Reliability stays poor. UK forwarder Metro Shipping said around 95% of scheduled sailings were expected to operate after China’s Golden Week, which points to modest capacity withdrawals [1]. It added that schedule adjustments, congestion, and disrupted rotations still hurt reliability even where capacity looks sufficient.
Bunched arrivals at US gateways. Ships that leave Asia together tend to arrive together. Plan for clustered discharges at Los Angeles/Long Beach and East Coast terminals rather than a steady weekly cadence. Clustering squeezes yard space, gate appointments, and drayage, which is where dwell turns into demurrage and detention for apparel, electronics, and consumer goods importers.
Softer spot, firmer risk. Extra deployed capacity weakens carriers’ hand on spot pricing for October and November loadings. It does nothing for terminal fluidity, so price landed cost on dwell exposure as well as ocean freight.
Your billing rights. The FMC’s demurrage and detention billing rule, 46 CFR Part 541, requires carriers to invoice within 30 days of the last charge and to give you at least 30 days to dispute, so log availability dates and challenge late or incomplete bills [2].
Carrier Surcharge & Landed Cost Impact Matrix
| Trade Corridor | Carrier Surcharge Type | Capacity vs Rest of Q3 | Impact per FEU | Effective Date |
|---|---|---|---|---|
| Asia to US West Coast | None announced; demurrage and detention per carrier tariff | +4% (393,000 TEU weekly) vs 2012-2019 avg of -8% | No published figure; softer spot leverage, higher dwell risk | Weeks 40 to 42; double sailings scheduled into November |
| Asia to US East Coast | None announced; demurrage and detention per carrier tariff | +15% vs 2012-2019 avg of -6% | No published figure; clustered discharge raises dwell risk | Weeks 40 to 42; double sailings scheduled into November |
3-Step Shipper Mitigation Action Plan
Recommended Next Steps:
- Track availability and audit every bill. Log terminal availability dates daily for October and November arrivals, and dispute any demurrage or detention invoice that’s late, inaccurate, or missing required details.
- Book drayage before vessels cluster. Secure appointments and chassis with your motor carriers ahead of bunched discharges, and pull high-priority apparel, electronics, and auto parts containers first.
- Trade spot leverage for free time. Use softer spot conditions to ask carriers for extended destination free time on current bookings, and split allocations across services so one bunched loop doesn’t stall your network.
