Peak Season Surcharges 2026: BAF, GRI, PSS, CAF Q4 Guide

In Q4 2026, ocean carriers typically stack four surcharge types on top of base rates: Bunker Adjustment Factor (BAF, fuel volatility pass through), General Rate Increase (GRI, standard mid quarter uplift), Peak Season Surcharge (PSS, capacity driven fee applied August through November), and Currency Adjustment Factor (CAF, USD volatility hedge). Air carriers layer their own per kilogram Peak Season Surcharge on Q4 cargo out of Asia, and parcel carriers (FedEx, UPS, DHL) add per package peak fees on the November to January holiday window. By the time the year closes, a shipper who did not budget the full stack can run 15 to 40 percent over plan on freight spend. This guide breaks each surcharge down with a plain English definition, the typical 2026 amount, when it hits, and how to cap it in your annual carrier RFP.

The Four Ocean Surcharges That Stack in Q4 2026

Ocean carriers do not raise the base rate the way a parcel carrier raises a published tariff. They keep the base rate line stable in the contract and layer four separately announced surcharges on top. Each surcharge answers a different question, each hits at a different point in the quarter, and each is negotiated on its own line in the annual RFP.

Amounts vary by lane. Trans-Pacific Eastbound and Asia to North Europe carry the highest surcharge stack in a Q4 peak year; intra-Asia and North-South trades typically sit at the low end of each range.

BAF (Bunker Adjustment Factor): Fuel Volatility Pass Through

What BAF Is

The Bunker Adjustment Factor is the surcharge ocean carriers use to pass through changes in fuel cost. Ocean vessels burn very low sulphur fuel oil (VLSFO) to comply with the IMO 2020 sulphur cap, and VLSFO prices move on the same commodity cycle as crude oil. Rather than repricing the base freight rate every time bunker fuel moves, carriers publish a BAF formula tied to a fuel index (Rotterdam, Singapore, or a blended benchmark) and reset the BAF line on a monthly or quarterly cadence.

Typical 2026 BAF Amounts

• Trans-Pacific Eastbound (Asia to US West Coast): $600 to $1,200 per TEU in a typical fuel environment; $1,200 to $1,800 per TEU in a high fuel quarter.
• Asia to North Europe: $500 to $1,100 per TEU.
• Intra-Asia: $150 to $400 per TEU.
• Formula transparency: Major alliance carriers (2M, Ocean Alliance, Premier Alliance) publish the BAF calculation formula on their tariff pages. Non-alliance and NVOCC BAF is often a fixed pass through that lags the index by 30 to 60 days.

How to Handle BAF in a Contract

Do not try to cap BAF in your RFP. Fuel is a genuine pass through and a hard BAF cap either loses you the bid or trips a force majeure clause when fuel spikes. Instead, negotiate the formula transparency (which index, what base fuel price, what recovery ratio) and the reset cadence (monthly gives you predictable line items; quarterly smooths volatility but creates lag). The Freight Rate RFP Playbook section on fuel clauses covers the standard formula language.

GRI (General Rate Increase): The Mid Quarter Base Rate Uplift

What a GRI Is

A General Rate Increase is a base rate uplift the carrier applies across a trade lane, usually mid quarter, when capacity tightens ahead of a demand event or contract renewal. Unlike BAF, a GRI is not tied to a formula. The carrier prices it against market conditions, files it under the applicable tariff, and gives 30 days notice.

Typical 2026 GRI Amounts

• Trans-Pacific Eastbound: $500 to $1,200 per TEU per event, with two to four GRI events in a typical calendar year.
• Asia to North Europe: $400 to $1,000 per TEU per event.
• North-South and intra-Asia: $200 to $600 per TEU per event.
• Realized rate vs announced GRI: In a soft market a carrier can announce a $1,000 GRI and realize only $200 to $400 of it as spot rates absorb the rest. In a peak year the full announced amount lands. Model both scenarios.

GRI vs PSS

Two questions that get conflated. A GRI is a base rate uplift the carrier keeps whether the market is at peak or not; it stays on the tariff after peak ends. A PSS is a peak season only fee tied to the August to November window and comes off the rate structure when peak ends. Both can hit in the same month.

PSS (Peak Season Surcharge): The August to November Capacity Fee

What a PSS Is

The Peak Season Surcharge is the capacity fee ocean and air carriers add during the highest demand window of the year. On ocean, that window is roughly August 1 through November 30 for trans-Pacific and Asia to Europe cargo (front loading of Q4 retail inventory). On air, the window opens in September and runs into January (holiday e-commerce plus Lunar New Year pre build).

Typical 2026 PSS Amounts

• Ocean trans-Pacific Eastbound: $500 to $800 per FEU (40 foot container) in a typical peak; $800 to $1,200 per FEU in a tight capacity year.
• Ocean Asia to Europe: $300 to $600 per FEU.
• Air ex-Asia: $0.30 to $1.20 per kilogram, sometimes higher on Hong Kong and Shanghai out lanes when belly capacity tightens.
• Announcement window: 30 to 60 days before effective date. Carriers can raise, extend, or cancel PSS in season based on real time load factor.

When Ocean PSS Hits

The typical ocean PSS calendar for a Q4:

• August 1: First PSS effective on trans-Pacific Eastbound as retail front loading kicks in.
• September 15: Second PSS wave on Asia to Europe as Christmas inventory ships.
• October 1 to November 30: PSS peak, layered with any additional GRI events.
• December 1 or 15: PSS typically comes off, but a strong Lunar New Year pre build can hold it through January.

Parcel PSS is Different

Parcel carriers (FedEx, UPS, DHL) publish per package peak surcharges each August for the November through January holiday window. These are NOT ocean or air PSS. Typical 2026 parcel PSS ranges:

Parcel peak fees are tiered by weekly package volume vs a shipper's baseline; the highest per package numbers hit shippers whose peak week volume runs 200 percent or more over baseline.

CAF (Currency Adjustment Factor): The USD Volatility Hedge

What CAF Is

The Currency Adjustment Factor is a percentage add-on ocean carriers apply on trades priced in a currency other than USD (or on trades where operating costs land in a currency other than the rating currency). CAF hedges the carrier against the difference between the rating currency and the currency the carrier actually spends. It shows up most often on Europe to Asia, intra-Europe, and intra-Asia trades priced in EUR, JPY, or GBP.

Typical 2026 CAF Amounts

• Range: 3 to 8 percent of the base rate on trades subject to CAF.
• Reset: Monthly on some lanes, quarterly on others. The carrier tariff page names the reset cadence.
• Not applied on all lanes: Most trans-Pacific Eastbound and Asia to US East Coast contracts are priced fully in USD and do not carry a CAF line. Check the tariff before assuming CAF applies.

CAF vs BAF

Both are pass throughs. BAF passes through fuel cost changes; CAF passes through currency exchange rate changes. On a Euro denominated Asia to North Europe contract you can see both lines on the same invoice.

Q4 2026 Ocean Surcharge Landscape

The current Q4 2026 announcement window on trans-Pacific and Asia to Europe follows the typical pattern: BAF resets on the monthly cadence, GRI events land at the start of September, October, and November, and PSS runs from early August through November 30 on trans-Pacific Eastbound.

Carrier announcement timing (CMA CGM, MSC, Maersk, Hapag-Lloyd, ONE, Evergreen, COSCO). In prior peak years the alliance carriers have moved within a few days of each other; the exact 2026 Q4 announcement dates for each carrier should be pulled from the tariff pages of your contracted lines and cross referenced against your Rate Management system before this line goes live.

The variables that will shape the final 2026 Q4 landscape:

• VLSFO fuel index trajectory. A quiet fuel quarter keeps BAF flat; a fuel spike drives a mid quarter BAF reset that carriers pass through in real time.
• US retail import pull. Front loaded retail volumes tighten trans-Pacific Eastbound capacity and support the full announced PSS; soft consumer demand weakens PSS realization.
• Asia to Europe demand. The Red Sea routing situation continues to add roughly 10 to 14 days on Asia to North Europe transit vs the Suez routing, keeping effective capacity tight and supporting PSS.
• Blank sailing cadence. Carriers manage capacity through blank sailings around National Day (October 1) and Golden Week to protect PSS realization.

The 30 Day Notification Rule: When Announcements Land and When They Take Effect

Under US Federal Maritime Commission (FMC) tariff filing rules, ocean carriers on US trades must file rate and surcharge changes with the FMC and publish them in the carrier tariff at least 30 days before the effective date. Most carriers use this rule as the standard announcement cadence globally, even on trades where FMC filing does not apply.

What this means for a Q4 budget calendar:

• PSS effective August 1 appears on the tariff by July 1 (or earlier for a 60 day announcement).
• GRI effective September 1 appears on the tariff by August 1.
• PSS revision or extension typically appears 30 days before the change.
• BAF monthly reset appears on the tariff on the first business day of the month it takes effect.

Set a recurring calendar reminder for the 1st and 15th of each month in the peak window to pull the current tariff from each contracted carrier. Spot rate NVOCCs and freight forwarders often announce with less notice than the alliance carriers; a 14 to 21 day window is common on spot business.

How Forwarders Forecast and Budget for Q4 Surcharges

Freight forwarders and shipper procurement teams that model the surcharge stack cleanly avoid the 15 to 40 percent Q4 budget miss. The three step model:

Step 1: Build the base rate line. Pull the contracted base rate from your Rate Management system for each lane, container size, and commodity. This is the number in your annual RFP award.

Step 2: Layer the four surcharges as separate lines. For each lane in your Q4 forecast, add:

• BAF at the current tariff amount, held flat for the quarter unless your BAF formula predicts a reset.
• GRI at the announced amount, discounted for realized rate. In a soft market, apply a 30 to 50 percent realization factor; in a peak year, apply 90 to 100 percent.
• PSS at the announced amount for the effective months, full realization in a peak year.
• CAF at the current percentage on any non-USD priced lane.

Step 3: Run a low and high scenario. Low scenario: soft market, half realization on GRI and PSS. High scenario: peak market, full realization plus one additional GRI event you have not seen announced yet. The gap between low and high is your Q4 budget contingency.

Where a Transportation Management System helps: the surcharge tracking has to happen at the shipment level so you can reconcile the carrier invoice against the tariff. Manual reconciliation on a spreadsheet works up to a few hundred shipments a month; above that you need a system that ingests the tariff, applies it to each shipment, and flags variances. GoFreight's Rate Management and Quoting module holds the tariff, the surcharge lines, and the shipment level application in one place.

Negotiating Surcharge Caps in Your Annual RFP

The leverage window for surcharge caps is the annual RFP, not the middle of Q4. Once a PSS or GRI is announced and effective, the carrier has almost no reason to negotiate a cap on a signed contract. In the RFP cycle, the carrier is competing for volume commitment and will accept structural clauses that limit surcharge exposure in exchange for the award.

The five clauses to negotiate:

1. PSS cap. A hard dollar cap on total PSS per FEU per calendar year (e.g., $600 per FEU aggregate PSS on the trans-Pacific Eastbound), or a cap on the number of PSS events (e.g., no more than two PSS events per calendar year).
2. GRI cap. A cap on the number of GRI events per year (typical: two to four), or a percentage cap on cumulative GRI (typical: no more than 25 percent above the base rate on aggregate GRI).
3. BAF formula transparency. The formula, index, base fuel price, and recovery ratio in writing. Do not accept "carrier standard BAF" as a contract term.
4. Minimum Quantity Commitment (MQC) balance. If your MQC is at risk, carriers can trigger deficit charges. Negotiate a two way clause: the carrier owes you rebate if capacity is short, you owe the carrier a deficit charge if volume is short.
5. Notification lead time. Contract a 45 or 60 day notice on any surcharge change instead of the 30 day tariff standard. This lets you rebid the lane on the spot market if the carrier moves aggressively.

The full 7 week process for running the tender is in the Freight Rate RFP Playbook, including the section on which clauses matter most to a mid market forwarder book vs an enterprise BCO book.

Air Freight Peak Season Surcharges 2026

Air carrier PSS on Q4 cargo out of Asia typically runs $0.30 to $1.20 per kilogram, with the highest per kilogram amounts on Hong Kong, Shanghai, and Guangzhou origin lanes when belly capacity tightens against pre holiday e-commerce demand. The 2026 air peak window opens in mid September and runs into January to cover Lunar New Year pre build.

The main air carriers announcing peak surcharges on Asia origin cargo include Cathay Cargo, Korean Air Cargo, Emirates SkyCargo, Lufthansa Cargo, Qatar Airways Cargo, FedEx, and UPS. Freighter capacity has recovered from the pandemic era distortions, but the underlying tightness on Hong Kong and Shanghai belly capacity keeps the PSS structure in place through the Q4 window.

Who Pays What: PSS, GRI, BAF, and CAF Responsibility

The surcharge stack is billed on the ocean freight invoice under the Incoterm the contract names. Under FOB, the buyer pays the ocean freight and every surcharge on it. Under CIF or CFR, the seller pays the ocean freight and every surcharge on it (but the buyer still pays every cost after arrival at the destination port). Under DDP, the seller pays every cost including the surcharge stack.

Freight forwarders and NVOCCs pass surcharges through to the shipper of record on the master bill of lading. A house bill of lading customer sees the NVOCC's blended rate, which may or may not itemize the underlying surcharge lines depending on the NVOCC's disclosure policy. Ask for a fully itemized rate sheet from any NVOCC that quotes a blended all-in.

Planning Strategy for 2026 Peak

The two operating questions for any forwarder or shipper going into a Q4 peak:

1. How much of your Q4 volume can you lock at contract rate vs spot? Contract rate insulates you from GRI and PSS on the covered volume; spot exposes you to the full announced stack. A 70 to 80 percent contract, 20 to 30 percent spot mix is the typical mid market position.
2. When do you rebid a lane the carrier moves aggressively on? If a contracted carrier announces a PSS above your negotiated cap and enforces it in tariff, that is a contract breach question. Most in season disputes settle with the carrier holding volume commitment against the shipper's threat to shift, so the leverage sits with whoever has more volume mobility.

Frequently Asked Questions

What is a peak season surcharge?

A Peak Season Surcharge (PSS) is a capacity fee ocean and air carriers add to base freight rates during the highest demand window of the year (August through November for ocean; September through January for air). It sits on top of the base rate as a separate line and is negotiated separately in the annual RFP. Typical 2026 amounts: $300 to $800 per FEU on ocean trans-Pacific and Asia to Europe, and $0.30 to $1.20 per kilogram on air ex-Asia.

What does BAF stand for in shipping?

BAF stands for Bunker Adjustment Factor. It is the surcharge ocean carriers use to pass through changes in fuel cost. Ocean vessels burn very low sulphur fuel oil (VLSFO) to comply with the IMO 2020 sulphur cap, and BAF resets on a monthly or quarterly cadence tied to a published fuel index. Typical 2026 range: $500 to $1,500 per TEU on major trades.

What is GRI in ocean freight?

GRI stands for General Rate Increase. It is a base rate uplift the carrier applies across a trade lane, usually mid quarter, when capacity tightens ahead of a demand event or contract renewal. Typical 2026 range: $500 to $1,200 per TEU per event, with two to four GRI events in a typical calendar year on trans-Pacific Eastbound.

How much is CAF in 2026?

CAF (Currency Adjustment Factor) typically runs 3 to 8 percent of the base rate on trades subject to it. CAF is applied on lanes priced in a currency other than USD (most often Europe to Asia, intra-Europe, and intra-Asia trades priced in EUR, JPY, or GBP). Most trans-Pacific Eastbound contracts are fully USD priced and do not carry a CAF line.

What is the difference between GRI and PSS?

A GRI is a base rate uplift the carrier keeps in the tariff whether the market is at peak or not; it stays on the rate structure after peak ends. A PSS is a peak season only fee tied to the August to November window and comes off the rate structure when peak ends. Both surcharges can hit in the same month during Q4 and are billed on separate invoice lines.

How much notice do carriers give before a surcharge?

Ocean carriers on US trades must file surcharge changes with the Federal Maritime Commission (FMC) and publish them in the carrier tariff at least 30 days before the effective date. Most carriers use this 30 day rule as the standard announcement cadence globally. NVOCCs and spot rate providers often announce with 14 to 21 days notice. Negotiate a 45 or 60 day contractual notice in your annual RFP.

Can I negotiate a PSS cap in my RFP?

Yes. The annual RFP is the leverage window. Carriers competing for a volume commitment will accept a hard dollar cap on total PSS per FEU per year, or a cap on the number of PSS events per year, in exchange for the award. Once PSS is announced and effective in season, the carrier has almost no reason to negotiate a cap on a signed contract. The Freight Rate RFP Playbook covers the standard cap clause language.

When does the 2026 Q4 peak season surcharge take effect?

The typical 2026 Q4 ocean PSS calendar: first PSS effective on trans-Pacific Eastbound August 1 as retail front loading kicks in; second PSS wave on Asia to Europe September 15; PSS peak October through November 30 layered with any additional GRI events; PSS typically comes off December 1 or 15, but a strong Lunar New Year pre build can hold it through January. Exact dates vary by carrier and appear on the tariff 30 days before effective.

How do parcel peak season surcharges work?

Parcel carriers (FedEx, UPS, DHL) publish per package peak surcharges each August for the November through January holiday window. FedEx Ground/Home Delivery peak fees run $1.40 to $7+ per package for 2026, plus $7 to $9 for additional handling and $60 to $80+ for oversize. UPS runs a similar structure. Parcel peak fees are tiered by weekly package volume vs the shipper's baseline; the highest per package numbers hit shippers whose peak week volume runs 200 percent or more over baseline.

How do freight forwarders budget for Q4 surcharges?

Forwarders model Q4 in three steps: build the base rate line from the annual RFP award, layer the four ocean surcharges (BAF, GRI, PSS, CAF) as separate lines with a realization factor for GRI and PSS, and run a low vs high scenario. Low: soft market, half realization on GRI and PSS. High: peak market, full realization plus one unannounced GRI event. The gap between low and high is the Q4 budget contingency. A Transportation Management System with rate and surcharge tracking at the shipment level replaces spreadsheet reconciliation above a few hundred shipments per month.
