General Rate Increase (GRI)

Definition

A General Rate Increase is a carrier-announced increase to ocean freight rates across a trade lane, effective on a specific date. GRIs are filed publicly and typically announced two to four weeks before implementation. Multiple carriers often announce GRIs on the same effective date.

Why it matters

A GRI changes the cost basis for every shipment booked after the effective date. If your team quoted a customer before the GRI and books after it, the margin on that shipment shrinks or disappears. Rate validation against current carrier tariffs is a recurring ops task.

How GRIs are announced and why they often fail

Carriers file GRIs publicly on their tariff portals and announce them via carrier advisories. The announced GRI increase is rarely the amount that sticks in the market. When market conditions are weak and shippers have options, the actual booked rate after the GRI effective date may be little changed from before it, because NVOCCs and large shippers simply reject the increase and book with carriers who offer contract rates. GRIs are more likely to stick during peak season when capacity is tight and alternatives are limited. Treating a GRI announcement as a confirmed rate increase before booking is a mistake.

GRIs and forwarder quoting exposure

A freight forwarder who quotes a customer an all-in rate valid for 30 days and then a GRI takes effect on day 15 faces a margin problem on any booking made after the effective date. The forwarder either absorbs the increase, re-quotes the customer, or books the cargo at the pre-GRI rate if the carrier honors it. Rate quote validity windows should be structured around known GRI effective dates. On trade lanes with heavy GRI activity (Asia-North America in particular), quoting with a validity of 7 to 14 days rather than 30 is the standard risk-management approach.

Peak Season Surcharges vs. General Rate Increases

A Peak Season Surcharge (PSS) is similar to a GRI but is framed as a temporary add-on for a specific period rather than a permanent base rate change. PSS announcements typically appear in June through August for the pre-holiday shipping surge, and again in the first quarter of the calendar year as Chinese New Year disruptions clear. The practical difference from a forwarder's perspective is that a PSS has a stated end date (which may or may not be honored), while a GRI is presented as a permanent adjustment. Both require the same quoting response: validate the current carrier rate before booking, not at the time of the customer quote.
