Do Shipping GRIs Stack? Lessons From Hapag-Lloyd's 2026 Rate Increases

Hapag-Lloyd has announced two general rate increases (GRIs) affecting the same three services from South America East Coast, with effective dates 14 days apart. From 1 November 2026, the announced increase is US$400 per standard container on the CON service to South America West Coast and US$300 on the GS1 and SEC services. From 15 November, Hapag-Lloyd has announced a further US$1,000 per standard container on all three services.

For November cargo, the key questions are which rate applies to your booking, whether the announced increase has been incorporated into that rate, and which shipment event determines its applicability. Hapag-Lloyd’s September GRI on CON explicitly covered dry containers gated in full from its effective date. The November notices give effective dates but do not specify the equivalent event in their published text. A terminal gate-in date, a legal cargo-receipt date and a vessel-loading date should not be treated as interchangeable without checking the governing tariff or rate agreement.

The 15 November notice provides a useful example of how to read a GRI announcement, distinguish it from a surcharge and check its potential effect on an actual shipment.

What is a general rate increase (GRI) in shipping?

A general rate increase (GRI) is an announced increase in ocean freight rates for a defined trade, service or set of cargo conditions. A notice typically identifies an effective date, amount and eligible equipment. Whether that increase changes what a particular shipper pays depends on the applicable tariff, contract or quote, and on subsequent rate changes. Separately applicable surcharges, such as bunker or peak season charges, may also affect the total.

Hapag-Lloyd’s 15 November notice describes the announced increase in terms of its Ocean Tariff rates and identifies additional charges that may apply. Here is how to read its main fields.

Field	What the notice says	What to check on your bookings
Amount	US$1,000 per standard container	Confirm which of your container types and commodity categories are covered; the notice does not provide a full equipment-code list
Services	CON: South America East Coast to South America West Coast GS1: South America East Coast to North America, Central America and the Caribbean SEC: South America East Coast to North America East Coast	Match the service, origin, destination and booking to the stated scope
Start	Effective 15 November 2026	Confirm the governing date or event under the applicable rate terms; the announcement does not define a gate-in or loading trigger
Validity	Until further notice	No scheduled expiry is stated; monitor later tariff amendments and rate updates
Rate type	Ocean Tariff rates	Check whether your shipment is priced under that tariff or a separate contract or quote
Other charges	Bunker, security, terminal handling and peak season charges (where applicable); local and contingency charges may also apply	Identify which charges actually apply and compare the agreed breakdown with the invoice

The effective date and the applicable rate terms deserve particular attention. The notice provides a date but does not say whether an individual shipment is assessed by full gate-in, carrier receipt or loading. “Until further notice” gives no automatic expiry date, but a later tariff amendment can change the applicable rate.

Is a GRI the same as a surcharge?

Generally, a GRI increases the underlying ocean freight rate, while a surcharge is assessed under a separately defined charging rule. A peak season surcharge, for example, may have its own amount and effective window. The difference is useful for understanding a quote, although invoice presentation varies: a GRI-related adjustment may be incorporated into the freight figure or separately itemized by a provider.

For invoice reconciliation, do not rely on finding—or not finding—a line labeled “GRI.” Compare the agreed freight basis and any applicable tariff amendments with the invoiced ocean freight, then check each surcharge against its own terms.

A windowed surcharge illustrates the distinction. In the CMA CGM Durban PSS case, the applicable charge depends on the stated loading window, and each window has an end date. Hapag-Lloyd’s November GRI announcements instead say “until further notice,” without an announced closing date.

When does a GRI take effect on my container?

Start with the applicable rate terms rather than assuming every carrier uses the same shipment event. Hapag-Lloyd’s 4 September CON increase explicitly applied to dry containers gated in full from that date. By comparison, CMA CGM’s rate announcement for Asia-to-Latin America cargo effective 15 October 2026 expressly used the date of loading. Hapag-Lloyd’s November 1 and November 15 notices give effective dates but do not specify either of those triggers in the announcement text.

For shipments in U.S. foreign ocean commerce moving under an applicable published carrier tariff, 46 CFR 520.7(c) ties the applicable tariff rate to the date the carrier or its agent receives the cargo, including receipt by an originating carrier in through transportation. That date is not necessarily the terminal gate-in date. Under 46 CFR 520.8, tariff increases generally require at least 30 calendar days between publication and effectiveness, subject to exceptions and a special-permission procedure. A carrier news announcement alone does not verify the publication details of every applicable tariff entry.

Those U.S. rules cannot be applied automatically to every GS1 or SEC shipment merely because the services include North American destinations. For non-U.S. routes, and for cargo moving under service contracts, negotiated rates or forwarder quotes, establish the governing terms with the carrier or contracting party. In all cases, distinguish terminal gate-in, carrier receipt and vessel loading when documenting what happened.

Worked example: two containers, one booking

Suppose two standard containers are associated with one US-bound GS1 booking. One is gated in full at the origin terminal on Friday, 13 November, and the other on Monday, 16 November. Assume, for this example only, that full gate-in is the relevant carrier-receipt event for both containers, the governing rate terms assess each container separately, and the tariff rate applicable from 15 November actually rises by the full announced US$1,000.

Under those assumptions, the later container would be charged US$1,000 more in ocean freight than the earlier one. But none of those assumptions is established for a particular booking by the GRI news notice. The containers might be rated together, the carrier might have received the cargo at a different point, or the applicable contract or tariff might produce a different price. A shared booking number alone does not settle the result.

Record each container’s actual events, then ask Hapag-Lloyd or your forwarder which rate, governing date and rating arrangement apply. Do this before changing delivery plans in an attempt to avoid an announced GRI.

If your team needs to compare gate-in and loading dates across containers, walk through how operations teams monitor available container-level tracking events across carriers.

Do GRIs stack? Hapag-Lloyd’s 2026 increases on the CON service

A sequence of announcements does not establish the cumulative change in the rate a shipper actually pays. Hapag-Lloyd has issued at least four 2026 GRI notices covering CON, each with a different effective date or equipment scope. All describe their validity as lasting until further notice, but the notices alone do not establish whether each increase was implemented in full, remained in place or was superseded by a later tariff change.

Effective	Announced increase on CON	Equipment named	Event stated
1 May 2026	US$200 per container	Dry, reefer and special	Effective from May 1; specific event not given
4 September 2026	US$600 per dry container	Dry	Gated in full
1 November 2026	US$400 per standard container	Standard	Effective from November 1; specific event not given
15 November 2026	US$1,000 per standard container	Standard	Effective from November 15; specific event not given

Selected Hapag-Lloyd CON-service GRI announcements in 2026, based on the carrier’s March, July, September and October notices. Amounts are announced increases, not verified resulting tariff rates. This is not an exhaustive history.

Adding the four amounts produces US$2,200, but that arithmetic is not a verified cumulative freight-rate increase. The May notice covered dry, reefer and special containers; September specified dry containers; and both November notices use the term “standard containers.” The carrier should confirm whether a particular equipment type is included in each notice.

MundoMaritimo’s October review of Latin American freight-rate announcements noted that implementation depends on market conditions. For an actual shipment, obtain the applicable tariff or agreed quote for its governing date and compare it with the invoice rather than summing earlier GRI announcements.

Does a GRI apply to my contract rate?

It depends on the pricing arrangement. Hapag-Lloyd describes the November increases as changes to its Ocean Tariff rates. Cargo moving under a service contract, negotiated rate arrangement or forwarder quote follows the applicable agreement, including its rate-validity and adjustment provisions. A carrier’s published GRI does not, by itself, establish what a shipper must pay under a separate agreement.

If you book through a forwarder, ask whether your rate is fixed, subject to GRI adjustments or linked to a published tariff, and which dates determine its validity. In 2026, contract structure matters as much as the rate covers how to separate fixed and floating components before the next tender.

What to check before 15 November

Service and route: Confirm whether the booking falls within CON, GS1 or SEC and the origin-to-destination scope of the notice.
Equipment and commodity: Ask whether your exact container type and cargo category are covered by the “standard container” wording.
Rate basis: Establish whether the shipment uses a published carrier tariff, service contract, negotiated rate or forwarder quote, and obtain the current rate in writing.
Applicable date: Confirm which event determines the rate and whether it is defined by the tariff or agreement. Do not assume full gate-in applies merely because September’s CON notice used it.
Container events: Record gate-in, carrier receipt where documented, and loading dates for the relevant containers, separate from the booking’s estimated departure date.
U.S.-bound shipments: If an FMC-governed tariff applies, verify the carrier-receipt date and the tariff rate effective on that date; check for through-carriage arrangements that may affect when receipt occurred.
Final charges: Check whether the GRI has actually been incorporated into the applicable rate and which bunker, security, terminal, peak season, local or contingency charges apply in addition.

The container events behind these checks, and where each one comes from, are mapped in container tracking milestones.

Frequently asked questions

What does GRI stand for in shipping?

GRI stands for general rate increase. It is an announced rise in ocean freight rates for a defined trade or service. The price charged to a particular shipment depends on its applicable tariff, contract or quote and any later rate changes.

How much notice does a carrier give before a GRI?

For increases to published tariffs in U.S. foreign ocean commerce, FMC rules generally require at least 30 calendar days between publication and effectiveness, with exceptions and a special-permission process. Other trades and negotiated pricing arrangements may follow different rules. Hapag-Lloyd’s October 14 news notice announced a November 15 effective date, but the news date alone does not verify every underlying tariff publication.

Does a GRI apply to reefer containers?

That depends on the notice and equipment coverage. Hapag-Lloyd’s May 2026 CON GRI expressly included reefer containers, while its November notices refer to “standard containers” without providing a complete equipment-code list. Confirm reefer eligibility rather than assuming it is included or excluded.

Is a GRI the same as a peak season surcharge?

Generally, no. A GRI is intended to raise the underlying freight rate, while a peak season surcharge is assessed under a separate charging rule. How a provider itemizes the amounts can vary. Hapag-Lloyd’s November 15 notice says peak season charges may apply in addition where relevant.
