A GRI's path through the market
The carrier publishes the increase, the lanes it covers and the effective date. In U.S. trades, a tariff change that raises a shipper's cost generally cannot take effect until 30 calendar days after it is published, which is why GRIs are usually announced weeks ahead. What happens next depends on demand. When space is tight, carriers tend to apply the GRI in full. When ships sail with room to spare, they may apply part of it, postpone it or drop it.
Tariff rates, contracts and spot quotes react differently
A GRI applies directly to tariff rates. Service contracts usually fix rates for their term, so a GRI reaches contract cargo only when the contract allows it or a shipment falls outside its scope. Spot and short-term quotes, including NVOCC quotes, tend to reflect announced GRIs quickly, sometimes before the effective date. Ask which pricing basis each booking uses and which date sets its rate.
Booking strategy when a GRI is announced
Effective dates reward planning. Moving cargo earlier can sometimes avoid a GRI, but rushing can mean missing documentation cut-offs or being rolled to a later sailing anyway. Compare the GRI with other moving parts such as BAF and peak season surcharges, since a quote's total can change even when the base rate does not. File the carrier's notice with the booking so the rate difference is easy to explain later.
Example
A carrier announces a GRI on its Asia to U.S. West Coast service effective the first of next month, so the forwarder checks which open bookings, including ONEU9051279, will be rated at the new level.

Questions
What does General Rate Increase (GRI) mean?
A general rate increase (GRI) is an increase a carrier applies to its base ocean freight rates across a trade lane from a stated effective date. Carriers announce GRIs in advance, and market demand decides how much of each one holds.
Does a GRI apply to cargo that is already booked?
It can. What matters is the date the tariff or contract uses to set the rate, such as when the cargo is received or when it sails, not only when it was booked. Check that rule before assuming a booking is protected.
Is a GRI the same as a surcharge?
No. A GRI raises the base freight rate itself. Surcharges such as BAF or PSS are separate line items that change on their own schedules.
