GRI and PSS Surcharges: What They Mean for Your Ocean Freight Rate

By ANKPOST Operations Team · 2026-06-12

What are GRI and PSS surcharges?

A General Rate Increase (GRI) is a carrier-announced across-the-board rate hike applied to a trade lane, typically announced 2-4 weeks in advance and implemented on the 1st or 15th of a month, while a Peak Season Surcharge (PSS) is an additional per-container fee layered on top of base rates during periods of seasonally high demand (typically late summer through early fall, ahead of the holiday retail season). Independent dispatch data indicates that GRI announcements for the transpacific eastbound lane to West Coast ports often see only 30-70% of the announced amount actually realized in the market by the effective date, depending on prevailing spot conditions, while PSS amounts in the $200-600/FEU range tend to track the severity of the capacity crunch more directly.

Cost structure / standard tiers

GRI and PSS amounts vary widely by year and market conditions, but follow a recognizable seasonal and announcement pattern.

Surcharge Type Typical Timing Typical Amount Range
GRI (transpacific eastbound) Announced 1st/15th of month, multiple times/year $200-1,000+ per FEU announced; 30-70% typically realized
PSS Late summer-early fall (pre-peak season) $200-600 per FEU additional
Contract rate insulation Annual service contracts GRI/PSS often capped or excluded under contract terms
Spot/overage cargo exposure Volume outside contracted allocation Full GRI + PSS stacking possible

Shippers with negotiated service contracts may have protections against GRI and PSS for contracted volume, but cargo shipped outside that allocation ("spot" or "overage" cargo) is typically subject to prevailing surcharges in full.

Risk mitigation / operational guidance

If shipping under spot rates, monitor GRI announcements for the relevant trade lane at least monthly during peak season planning, and consider booking ahead of announced effective dates when cargo timing allows flexibility — booking ahead locks in pre-increase rates for already-confirmed shipments. For recurring volume, negotiate annual service contracts that explicitly address GRI and PSS treatment, including caps or exclusions, rather than assuming a quoted spot price includes all applicable surcharges. Build budget contingency of 10-20% above base freight rates during the peak season window, since PSS stacking with GRI announcements is common. Compare quotes from multiple carriers/NVOCCs when a GRI is announced — implementation rates vary by carrier, and not every announced increase is fully realized.
