Ocean Freight GRI Calendar: When Rates Rise From China

Last updated: November 2026

Quick answer: A general rate increase (GRI) is a carrier-announced rise in the base ocean freight rate on a specific trade lane, effective from a fixed date — in current practice usually the 1st or 15th of a month — and applied per container (the GRIs filed for December 1, 2026 on the East Asia–USA lane run USD 2,000–3,000 per 40-ft container). On trades bound for the United States, carriers must publish the increase in their tariffs at least 30 days before it takes effect; on other lanes, notice is whatever each carrier's advisory says. Cargo that is booked and gated in at the origin terminal before the effective date usually ships at the pre-GRI rate — confirm the exact trigger (gate-in, booking or loading date) in writing with your forwarder.

If you buy from China and ship by ocean, GRIs are the single most predictable kind of rate shock in an otherwise noisy market. This guide explains how the GRI calendar works, when increases cluster, how much warning you get on each major trade, and what to do in the weeks before an effective date.

What a GRI is — and what it is not

A GRI raises the base ocean freight component of a carrier's tariff, typically quoted as a flat amount per TEU or per FEU (20-ft or 40-ft container), with other container sizes adjusted "as per formula" in the tariff. It is announced in advance, takes effect on a stated date, and stays in the tariff until the carrier changes it again.

A GRI is not the same thing as the other increases that appear on an ocean quote, and mixing them up is the most common reason buyers misjudge their real exposure:

The practical difference: a GRI moves the floor, and surcharges then stack on top of it. When carriers announce a GRI and a PSS in the same month, the two add up on your quote even though only the GRI makes headlines.

The GRI calendar: what it is and where it comes from

There is no law that fixes a global GRI calendar. The "calendar" is market practice: on the big eastbound trades out of Asia, carriers file increases in waves, usually timed for the 1st or 15th of a month, and those waves cluster around two commercial seasons:

• Pre-peak (roughly May–August): building rates into the transpacific and Asia–Europe summer peak.

• Pre-Chinese New Year (roughly December–January): the strongest window of the year, when exporters rush cargo out of China before factories close. GRIs filed in this window ride on genuine capacity shortage, so they tend to stick more often than off-season attempts.

The current season is a textbook case. On the East Asia–USA lane alone, carriers filed GRIs effective November 15, 2026 (the 22nd GRI of 2026 on that lane) and December 1, 2026 (the 23rd), at USD 2,000–3,000 per 40-ft container across CMA CGM, COSCO, Evergreen, Hapag-Lloyd, HMM, Yang Ming and ZIM (DPI Signals, retrieved 2026-11-11). That is roughly one announced increase every two weeks for a year — which is exactly why importers need a planning calendar rather than a reaction habit.

What's live on major lanes from China right now

Checked against carrier advisories and tariff reporting on November 11, 2026. Amounts are as announced by the carriers; whether an increase holds at those levels is a separate question (see below).

The evergreen pattern to plan against

Year to year, the dates move but the rhythm repeats. A planning grid importers can reuse every year:

This pattern is a planning reference, not a promise — route mix, transshipment, capacity and customs all change outcomes on specific sailings.

The notice clock: how much warning you actually get

To the United States — 30 days, by regulation. Under 46 CFR § 520.8(a), no change in a carrier's tariff that increases cost to a shipper may become effective earlier than 30 calendar days after publication (rate decreases can be immediate). The rule covers both ocean common carriers and NVOCCs filing their own tariffs — which is why your freight forwarder's NVO tariff also shows 30-day GRI notices (see C.H. Robinson's advisory, for example). Practically, this means a December 1 GRI on a US-bound lane was public by roughly November 1.

To Europe — individual announcements, no joint calendar. The EU's Consortia Block Exemption Regulation (CBER) expired on 25 April 2024, after the European Commission decided not to extend it. Carriers on EU trades now set prices individually under general EU competition law — "each carrier maintains its own tariffs and controls its own pricing," as DPI's tariff reporting puts it. You still get advance advisories (MSC's two-week FAK windows are published in advance), but there is no unified filing calendar, so forwarders track carrier bulletins lane by lane.

Everywhere else — carrier practice only. Intra-Asia, Asia–Australia, Asia–Latin America and Africa trades have no statutory notice period; increases arrive as carrier advisories, often with shorter warning. Treat anything less than two weeks as normal on these lanes.

Why GRIs cluster before Chinese New Year

The pre-CNY window compresses a quarter of export volume into six weeks. Factories push orders out ahead of the shutdown, every container vies for the same sailings, and carriers respond with GRIs because full ships let increases hold. Booking windows shrink at the same time — ocean space from China typically needs booking 4–6 weeks ahead in late December and January, versus 2–3 weeks in ordinary months, as covered in our Chinese New Year shipping timeline.

This season the mechanism is visible: with Shanghai–Los Angeles spot near USD 7,539 per 40-ft container on November 5 (Drewry WCI, versus roughly USD 2,089 a year earlier), analysts expected rates to hold between USD 7,000–8,500 through end-November and identified the December 1 GRI wave as the next real test of carrier pricing power — with at least one more FAK round on Asia–Europe timed to tender season (Forwarder News, 2026-10-20, retrieved 2026-11-11).

Do announced GRIs actually stick?

Not automatically — and this is where a calendar saves real money. An announced GRI is a filed intention, not a settled market price:

• Sea-Intelligence's long-running GRI analyses measure how much of an announced increase is actually realized at implementation, and find success varies with capacity and demand rather than following the announcement (Sunday Spotlight issue 399, retrieved 2026-11-11).

• Right now, the two directions are both on display: Drewry judged mid-November Asia–Europe FAK increases uncertain to hold because ample capacity is returning (blank sailings on the lane fell from six to two as Suez routings resumed), while transpacific GRIs headed into a demand-heavy December from an already elevated base (Forwarder News tracker and reporting, retrieved 2026-11-11).

• The failure mode is quiet: when an increase doesn't hold, carriers don't announce a cancellation — the market rate simply settles below the filed level, and only shippers who quote around discover it.

The planning rule: never pre-pay an announced GRI on the assumption it is final, and never assume it will fail either. Get a fresh quote dated within days of your booking, and ask your forwarder specifically whether the GRI applies to your sailing.

How to plan bookings around the GRI calendar

A six-step routine for any importer with recurring China volumes:

1. Know your lane's effective dates. Ask your forwarder for the current GRI/PSS calendar on your specific lane pair (e.g. Shanghai → Los Angeles or Ningbo → Rotterdam), not "Asia in general". Dates differ by carrier and lane.

2. Fix quotes with validity that outruns the effective date. A spot quote should state its validity window in writing. A quote that expires the day before a GRI is a quote you cannot use for the cargo you actually have.

3. Gate in before the trigger date. Carriers key the applicable rate to a defined moment — most commonly when the container is gated in at origin (Hapag-Lloyd's December 1 GRI from the Indian Subcontinent and Middle East applies to "containers gated in from December 1"), sometimes the booking or loading date. Get the trigger in writing for your specific booking.

4. Check whether the increase touches contract cargo. The December transpacific filings illustrate the range: COSCO's GRI applies only to service-contract cargo, while others target tariff/spot cargo. If you ship on annual contracts or named-account rates, your exposure to a spot GRI may be limited — or a service-contract GRI may be the one that matters. Verify against your own contract terms before assuming either way.

5. If you miss the window, price the alternatives. Paying the GRI, rolling to a later sailing, topping up urgent units by air, or splitting the shipment each cost different amounts; the air-versus-ocean trade-off has a real break-even and we break it down in when an air top-up beats pulling ocean freight forward.

6. Budget with a GRI buffer in peak windows. In December–January and pre-peak months, carry a contingency on the ocean line of your landed-cost model rather than a single point estimate.

What a GRI does to your landed cost

The GRI lands on the ocean freight line only — but it moves your all-in number. When you compare quotes, make sure increases are compared on the same all-in basis (base + BAF + PSS + origin and destination charges), which is exactly what our guide to what "all-in" means on a freight quote covers. For a quick read of where container spot rates stand on major corridors, use our container price index tool before you accept "the GRI is coming" as a reason to overpay.

Lane context matters when you plan: door-to-door transit on sea freight from China to the US runs much longer than to Europe or Australia, so a missed December booking doesn't just cost the GRI — it lands your cargo weeks later. The same math applies on the China to Netherlands corridor and China to Australia freight — both saw their own November increases.

Questions to ask your forwarder before the next effective date

Copy this list into your next email:

• Which GRI, PSS or FAK filings are currently in effect or pending on my exact lane pair, with effective dates?

• What trigger decides which rate applies to my cargo — gate-in date, booking date or loading date? Can you confirm it in writing?

• Is my quote valid through my intended gate-in date, including any pending increase?

• Does the pending increase apply to my cargo at all (spot vs. service contract vs. named-account rate)?

• If my container misses the pre-GRI sailing, what exactly does the next option cost — GRI amount, roll risk, and earliest arrival?

• What is the current booking-to-sailing lead time on this lane, and how does it change in the pre-CNY window?

FAQ

What does GRI mean in shipping? GRI stands for general rate increase: a carrier-announced rise in the base ocean freight rate on a trade lane, applied per container from a fixed effective date. It affects the base rate only — surcharges such as peak-season surcharges (PSS) and fuel (BAF) are separate line items on a quote.

How much notice do carriers give before a GRI? On trades to and from the United States, at least 30 calendar days: under 46 CFR § 520.8(a), a tariff change that increases a shipper's cost cannot take effect earlier than 30 days after publication. On European trades each carrier announces individually (the EU consortia block exemption expired in April 2024), and on intra-Asia, Oceania, Africa and Latin America trades there is no statutory notice period — two weeks or less is common.

When are GRIs usually effective? In current practice on major Asia export lanes, effective dates cluster on the 1st or 15th of a month — the filings live in November 2026 (Nov 1, Nov 15, Dec 1) all follow that pattern. Waves concentrate ahead of the summer peak and ahead of Chinese New Year.

Can I avoid a GRI by booking earlier? Usually, if the cargo is ready in time. What matters is the tariff's trigger — commonly the container's gate-in date at origin, sometimes the booking or loading date. Book, confirm quote validity in writing, and gate in before the effective date.

Does a GRI apply to contract rates or only spot rates? It depends on the filing and your contract. Some GRIs target tariff/spot cargo only; others apply to service-contract cargo — COSCO's December 2026 transpacific GRI, for example, applies to service contracts. Check the filing scope and your own contract terms rather than assuming either way.

Do GRIs affect air freight or rail freight from China? "GRI" is an ocean-tariff term with its notice rules tied to ocean tariff regulation. Air freight and China–Europe rail see their own seasonal peaks and surcharges, but they are priced and announced differently — ask for the seasonal surcharge calendar rather than a GRI calendar for those modes.

Do announced GRIs always take effect? No. Whether an announced increase is realized depends on capacity and demand; on loose markets the settled rate can end up well below the filed level, while in tight windows GRIs hold and even exceed target. Independent analysts such as Sea-Intelligence track exactly this realization rate, and trade press reports which rounds are expected to hold.

How do I track GRI dates for my lane? Ask your forwarder for the pending filings on your specific lane pair, watch carrier customer advisories, and for US-bound cargo remember the 30-day publication rule means filings are visible about a month ahead. Aggregators (tariff publishers and trade-press trackers) compile the calendar lane by lane.
