Ocean Freight Explained: Rates, FCL vs LCL, Carrier Alliances & 2026 Market Guide

Quick Answer: Ocean freight is the transportation of goods by cargo vessel across seas and oceans, accounting for over 90% of global trade by volume. Ocean freight services include Full Container Load (FCL), Less than Container Load (LCL), bulk cargo, Ro-Ro, reefer, and breakbulk. Rates are determined by a combination of base freight rates, surcharges (BAF, THC, PSS), and market forces including carrier alliance capacity management, seasonal demand, and geopolitical disruptions. Transit times range from 3 days for intra-Asia to 40+ days for Asia-Europe currently routing around the Cape of Good Hope.

Over 90% of everything traded globally moves by sea. The container on the vessel crossing the Pacific right now carries the raw materials, finished goods, and components that keep global supply chains running. Yet most guides to ocean freight treat it as a simple process: book a container, ship it, clear customs. The commercial reality is far more complex. Ocean freight rates can swing 300% in a single quarter. Carrier alliances control vessel deployment across entire trade lanes. Blank sailings remove capacity overnight. Geopolitical disruptions reroute vessels around entire continents.

This guide covers ocean freight the way a former Maersk Broker explains it, including the mechanics that most logistics guides never touch.

What Is Ocean Freight?

Ocean freight, also called sea freight, is the transportation of goods via cargo ships across oceans and seas. According to UNCTAD's Review of Maritime Transport, approximately 11 billion tonnes of cargo moves by sea every year, making ocean freight the backbone of international trade. By volume, over 90% of globally traded goods travel by sea at some point in their journey from producer to consumer.

Ocean freight is the preferred mode for high-volume, heavy, or non-time-sensitive cargo because of its cost efficiency. The cost per tonne-kilometre for ocean freight is significantly lower than air, road, or rail for long-distance international shipments. The primary tradeoff is transit time: where air freight delivers in 2-7 days, ocean freight takes 14-45 days depending on the trade lane and routing.

The parties involved in an ocean freight shipment are: the shipper (cargo owner exporting goods), the consignee (cargo owner receiving goods), the carrier (shipping line operating the vessel), the freight forwarder (logistics coordinator acting for cargo owner), the customs broker (handling import/export clearance), and the port agent (representing the vessel at the port of call).

How Ocean Freight Works: Step by Step

An ocean freight shipment passes through ten distinct stages from booking to final delivery. Each stage involves specific handoffs, documents, and decision points.

Step 1: Cargo Booking

The shipper or their freight forwarder contacts the carrier (shipping line) or an NVOCC to book container space on a specific sailing. The booking specifies cargo type, container size, origin and destination ports, and requested sailing date. The carrier issues a booking confirmation with a booking number, cut-off dates, and terminal assignment.

Step 2: Shipping Instruction (SI)

After booking, the shipper submits a Shipping Instruction (SI) to the carrier. The SI contains all details needed to produce the Bill of Lading: shipper and consignee details, cargo description, weight, volume, package count, and marks and numbers. The carrier uses the SI to generate a draft Bill of Lading for shipper approval.

Steps 3-4: Export Haulage and Container Stuffing

The cargo moves from the shipper's facility to the container freight station (CFS) for LCL shipments, or to the terminal for FCL. FCL cargo is stuffed (loaded) into the container at the shipper's facility or a designated depot. The forwarder coordinates container collection from the carrier's depot and returns it loaded before the terminal cut-off time.

Step 5: Export Customs and Terminal Cut-off

Export customs clearance must be completed before the terminal cut-off — typically 24-48 hours before vessel departure. The forwarder submits the export declaration, and the terminal receives the loaded container. Missing the cut-off means the cargo waits for the next available sailing, with demurrage charges potentially starting.

Steps 6-7: Vessel Loading and Ocean Transit

The container is loaded onto the vessel using gantry cranes at the container terminal. The carrier issues the original Bill of Lading after vessel departure. During ocean transit, the vessel's AIS (Automatic Identification System) transponder broadcasts position data that shipper-facing tracking platforms use for real-time visibility. The carrier monitors Estimated Time of Departure (ETD) and Estimated Time of Arrival (ETA) and issues updates for any deviations due to weather, port congestion, or schedule changes.

Steps 8-10: Arrival, Customs, and Delivery

On arrival, the vessel is discharged at the destination terminal. The consignee or their customs broker files the import entry, pays applicable duties, and collects the cargo after customs release. For FCL, the container is delivered to the consignee's facility or a designated depot where it is unpacked (devanned) and the empty container returned to the carrier within the free time window. For LCL, cargo is deconsolidated at the destination CFS before delivery. Late container return triggers detention charges.

Ocean Freight Service Types

Ocean freight is not a single service. Eight distinct service types serve different cargo characteristics, volumes, and commercial requirements.

Service Type	What It Is	Best For	Key Consideration
FCL (Full Container Load)	Single shipper occupies entire container	Volumes above ~15 CBM; high-value or fragile cargo	Fastest, least handling, best security
LCL (Less than Container Load)	Multiple shippers share one container	Small shipments below 15 CBM; test shipments	Adds 4-7 days for CFS handling at each end
Ro-Ro (Roll-on/Roll-off)	Wheeled cargo drives onto vessel via ramp	Vehicles, trucks, heavy machinery	No crane required; limited destination ports
Reefer (Refrigerated)	Temperature-controlled container, -30°C to +30°C	Perishables, pharmaceuticals, dairy, meat	Higher cost; power supply at terminal essential
Dry Bulk	Unpackaged homogeneous cargo in vessel hold	Grain, coal, iron ore, fertiliser	Chartered vessel, not container — separate market
Liquid Bulk / Tanker	Liquid cargo in vessel tanks or tank containers	Crude oil, chemicals, LNG, LPG, edible oils	Tanker market is separate from container
Breakbulk / Project Cargo	Individual pieces loaded onto vessel — not containerised	Oversized machinery, turbines, steel structures	Port equipment and handling specialist required
RORO + MAFI Trailer	Heavy cargo on MAFI trailer rolled onto RORO vessel	Mining equipment, large transformers	Suitable where crane clearances are insufficient

Container Types in Ocean Freight

Container Type	External Dimensions (L x W x H)	Max Payload	CBM Capacity	Best Use
20ft Standard (TEU)	6.1m x 2.4m x 2.6m	~28,000 kg	~33 CBM	Dense, heavy cargo; chemical drums
40ft Standard (FEU)	12.2m x 2.4m x 2.6m	~27,500 kg	~67 CBM	General cargo; balanced weight/volume
40ft High Cube (HC)	12.2m x 2.4m x 2.9m	~27,000 kg	~76 CBM	Lightweight, voluminous cargo; furniture
20ft Reefer	5.9m x 2.3m x 2.3m internal	~27,500 kg	~28 CBM	Temperature-sensitive cargo
40ft Reefer	11.6m x 2.3m x 2.3m internal	~27,000 kg	~60 CBM	Large perishable or pharmaceutical shipments
Open Top	12.2m x 2.35m x 2.35m internal	~27,500 kg	~67 CBM	Crane-loaded oversized cargo
Flat Rack (20ft)	5.9m x 2.4m, no sides	~40,000 kg	N/A	Heavy machinery, vehicles, steel coils
Tank Container	ISO frame, various capacities	~25,000 kg liquid	~21,000 litres	Chemicals, food-grade liquids, fuels

Vessel Classes and Carrier Alliances

Understanding vessel class and carrier alliance structure gives cargo owners insight into schedule reliability, space availability, and rate dynamics that no logistics guide typically covers.

Vessel Classes

Class	TEU Capacity	Primary Trade Lanes	Key Implication for Shippers
Feeder	Under 3,000 TEU	Intra-Asia, Caribbean, Short-sea Europe	Calls smaller ports; transhipment to mainline vessels required
Sub-Panamax	3,000-5,000 TEU	Regional trade lanes	Limited to ports with lower draft restrictions
Panamax / New Panamax	5,000-14,500 TEU	Transpacific, Asia-LatAm, major East-West	Can transit Panama Canal; reliable port call sequence
Post-Panamax	14,500-18,000 TEU	Asia-Europe, Transpacific mainline	High capacity; longer port stays; roll risk if cargo misses cut-off
ULCV / Megaship	18,000-24,000+ TEU	Asia-Europe (Suez/Cape), Asia-US	Fewest vessels, longest port stays, highest roll risk but lowest cost per TEU

Carrier Alliances (2025)

The three major carrier alliances control vessel deployment on the world's major East-West trade lanes. Alliance membership determines which vessels call which ports, how slot swaps work, and how schedule reliability varies across services.

Alliance	Members	Launch / Status	Trade Lane Focus
Gemini	Maersk + Hapag-Lloyd	Launched February 2025; replaced 2M	Asia-Europe, Transpacific — focus on schedule reliability (90%+ OTP target)
Premier Alliance	ONE, HMM, Yang Ming	Launched February 2025; replaced THE Alliance	Asia-Europe, Transpacific, Asia-Middle East
Ocean Alliance	CMA CGM, COSCO, Evergreen	Continuing from 2017	Asia-Europe, Transpacific, Asia-US East Coast via Panama

Alliance membership affects shippers in three practical ways. First, slot availability: a shipper booking with Maersk may find their cargo moving on a Hapag-Lloyd vessel under the Gemini alliance's shared vessel programme. Second, schedule reliability: Gemini's 2025 design prioritises fewer port calls and higher OTP, which means more predictable arrival windows. Third, rate coordination: while alliances do not fix rates (prohibited under competition law), coordinated capacity management through blank sailings and vessel sharing affects effective market supply.

Ocean Freight Rates: How They Are Formed

Ocean freight rates are among the most volatile pricing mechanisms in global trade. Understanding rate formation helps cargo owners time bookings, negotiate contracts, and avoid being caught by avoidable surcharges.

Base Freight Rate

The base freight rate is the carrier's charge for transporting a container between two ports, quoted per TEU or FEU. It does not include terminal handling charges, surcharges, or destination delivery. Base rates fluctuate with supply and demand on each trade lane and are published as spot rates for immediate shipment or fixed for a contract period.

General Rate Increases (GRIs)

Carriers announce General Rate Increases (GRIs) to raise spot market rates, typically with 30 days' notice. A GRI announcement does not guarantee that rates will actually increase — the market absorbs or rejects GRIs depending on demand levels and available capacity. During periods of high demand and tight capacity (as in 2021-2022 and mid-2024), GRIs stick. During periods of overcapacity (as through most of 2025), GRIs are frequently unsuccessful.

Blank Sailings

A blank sailing occurs when a carrier cancels a scheduled departure, removing vessel capacity from a trade lane without operating the service. Carriers use blank sailings to reduce effective supply during periods of low demand, supporting freight rates. During the H2 2025 tariff war volume contraction on transpacific lanes, carriers deployed blank sailings to limit the rate decline that would otherwise follow from excess capacity. The Cancelled Sailings Tracker published by Drewry is a key tool for cargo owners monitoring capacity risk on their trade lanes.

Spot vs Contract Rates

Spot rates are quoted for immediate or near-term bookings and reflect current market conditions. Contract rates are negotiated annually (or quarterly) between shippers and carriers, providing rate predictability in exchange for volume commitments. A common strategy among large cargo owners is the 80/20 or 90/10 model — covering 80-90% of volume under contract and leaving 10-20% for spot market booking to capture opportunistic low rates. A lane generally needs 1,000-1,500 TEU per year before a long-term contract provides meaningful cost savings, according to Freightos market analysis.

Asia to Latin America	25-35 days	30-40 days	N/A	Mixed routing; Cape adds 5-8 days

Ocean Freight and IMO Decarbonisation (2025-2030)

Ocean freight is entering a period of significant regulatory-driven cost change. Three overlapping frameworks are adding new costs to vessel operations, which carriers pass to shippers through explicit surcharges or higher base rates.

CII (Carbon Intensity Indicator)

CII rates vessels annually from A (best) to E (worst) based on carbon intensity, grams of CO2 per tonne-nautical mile. Vessels rated D or E for three consecutive years face operational restrictions. In practice, CII has pushed some older, less efficient vessels out of mainline trade lanes, tightening effective capacity slightly. For shippers, booking space on newer, more efficient vessels reduces the risk of cargo being rolled due to slow steaming or vessel retirement.

EU Emissions Trading System (EU ETS)

From January 2024, ships calling EU ports must surrender EU Allowances (EUAs) for covered voyages. Coverage phases in: 40% of emissions covered in 2024, 70% in 2025, and 100% from 2026. Carriers have introduced ETS surcharges on Europe-trade invoices. At an EUA price of EUR 50-70 per tonne CO2 (2024-2025 range), ETS adds approximately EUR 50-150 per TEU on Asia-Europe shipments.

FuelEU Maritime and IMO Net Zero Framework

FuelEU Maritime, effective 2025, mandates progressive reductions in the greenhouse gas intensity of energy used on board EU-traded vessels. The IMO's Net Zero Framework, adopted at MEPC 83 in 2025, establishes a GHG Fuel Intensity (GFI) standard, a remedial unit system, and a levy mechanism targeting net zero by 2050. For cargo owners, these frameworks translate into higher carrier operating costs throughout the 2025-2030 period, most visibly in Europe-trade surcharges.

2025-2026 Ocean Freight Market Outlook

Ocean freight is entering 2026 shaped by four structural forces: Red Sea rerouting, fleet overcapacity, US tariff war volume disruption, and carrier alliance restructuring.

Red Sea and Cape of Good Hope

Since December 2023, Houthi attacks on commercial vessels in the Red Sea have forced almost all Asia-Europe container services to reroute around the Cape of Good Hope, adding 7-10 days of transit time and absorbing significant vessel capacity. As of mid-2026, most Asia-Europe services continue on Cape routing. Carriers are beginning cautious assessments of Suez Canal return, which, when it occurs will release a significant block of effective capacity back into the market, putting downward pressure on Asia-Europe rates through a transition period of congestion at European hub ports.

Fleet Overcapacity

Fleet growth from the record newbuild orderbook placed in 2021-2022 continued to deliver vessels into an already overstocked market through 2025. According to BIMCO, fleet growth outpaced demand growth on major trade lanes, driving year-on-year rate declines across 2025 despite the capacity absorbed by longer Cape routings. This overcapacity dynamic is expected to persist into 2026 and represents structural downward pressure on base rates for shippers with sufficient volume to negotiate contract terms.

US Tariff War Volume Dynamics

The US-China trade war intensification in 2025, with tariff escalation through H1 2025, drove significant frontloading of imports ahead of tariff implementation. According to National Retail Federation data, US container import volume fell 1.4% overall in 2025 as H2 volumes contracted sharply following H1 frontloading. S&P Global projects a further 2% US import volume decline in 2026. For transpacific shippers, this demand volatility translated into rate swings of 20-40% across the year, with H1 rates elevated by frontloading demand and H2 rates softening with volume contraction.

Carrier Alliance Reshuffling

February 2025 saw the dissolution of the 2M alliance (Maersk and MSC) and THE Alliance, replaced by Gemini (Maersk and Hapag-Lloyd) and Premier Alliance (ONE, HMM, Yang Ming). Gemini's founding principle is schedule reliability, targeting 90%+ On-Time Performance through a hub-and-spoke network with fewer port calls per service. Early 2025 data showed Gemini outperforming legacy alliances on OTP, but the reduced port call structure means some smaller ports lose direct mainline calls and must rely on feeder connections.

Ocean Freight Costs: What You Actually Pay

A freight invoice for an ocean shipment contains multiple line items beyond the base freight rate. Experienced cargo owners understand each component and challenge unjustified charges.

Cost Component	What It Covers	Who Pays	Indicative Range (2025)
Base Freight Rate	Container transport origin to destination port	Shipper (or seller, per Incoterm)	Asia-Europe: $2,000-$4,000/FEU; Asia-USWC: $1,800-$3,500/FEU
THC (Origin)	Terminal handling at port of loading	Usually shipper	$150-$350 per TEU
THC (Destination)	Terminal handling at port of discharge	Usually consignee	$100-$300 per TEU
BAF	Bunker fuel adjustment	Shipper or consignee	$50-$400 per TEU (market dependent)
EU ETS Surcharge	Carbon cost on EU-trade shipments	Shipper (passed by carrier)	~EUR 50-150 per TEU (2025)
Documentation Fee	B/L issuance and processing	Shipper	$50-$150 per shipment
Customs Brokerage	Import entry filing	Consignee / importer	$150-$500 per entry
Detention	Late container return after free time	Consignee	$100-$300 per day per container
Demurrage	Late container collection from terminal	Consignee	$100-$400 per day per container

How to Choose an Ocean Carrier or Shipping Partner

The lowest freight quote is rarely the lowest total shipping cost. Carrier reliability, port call sequence, schedule frequency, and documentation accuracy all affect actual landed cost.

Carrier On-Time Performance

Sea-Intelligence, the leading carrier performance data provider, publishes monthly On-Time Performance (OTP) data by carrier and trade lane. OTP measures the percentage of sailings arriving within 24 hours of their published schedule. In 2024, average global OTP across all carriers was approximately 60-65%, meaning one in three sailings arrived more than a day late. Gemini alliance services targeted 90%+ OTP from launch in February 2025 — a significant premium over the market average.

Service Contract vs Spot

A service contract with a carrier commits the shipper to a minimum volume over the contract period (typically annual) in exchange for a fixed freight rate. Contracts provide rate certainty and space priority, but impose penalties for volume shortfalls. Most experienced cargo owners use a portfolio approach: 70-90% of volume covered by contract on high-frequency lanes, with the balance managed on the spot market. Lanes with fewer than 1,000-1,500 TEU annual volume generally do not justify the administrative burden of a long-term contract.

9-Point Evaluation Checklist

1. On-Time Performance score on your specific trade lane (Sea-Intelligence data)

2. Vessel frequency: weekly vs bi-weekly service on your route

3. Port call sequence: direct service vs transhipment (adds 3-7 days and roll risk)

4. Alliance membership and vessel sharing implications

5. Financial stability of the carrier (credit rating, published annual results)

6. eBL capability: can they issue electronic bills of lading?

7. Claims handling track record: speed and success rate of cargo damage claims

8. Blank sailing frequency: how often do they cancel sailings on this lane?

9. Customer service and single point of contact quality

Frequently Asked Questions

What is the difference between ocean freight and sea freight?

Ocean freight and sea freight are the same thing — the transportation of goods by cargo vessel across international waters. Sea freight is the more commonly used term in British English; ocean freight is preferred in American English and in international commercial contexts. Both terms refer to all types of cargo vessel shipping including container, bulk, tanker, and Ro-Ro.

What does FCL mean in ocean freight?

FCL stands for Full Container Load. An FCL shipment means one shipper's cargo occupies an entire container — a 20-foot TEU, 40-foot FEU, or 40-foot High Cube. The shipper pays for the full container regardless of whether the cargo fills it. FCL offers faster transit (no CFS handling), better security, lower cargo damage risk, and direct container delivery. It becomes cost-effective when cargo volume exceeds approximately 15 CBM.

What is LCL shipping and when should I use it?

LCL (Less than Container Load) means multiple shippers' cargo is consolidated into one container at a container freight station (CFS). Each shipper pays only for the space their cargo occupies, typically rated per CBM or per tonne (whichever is greater). LCL adds 3-5 days at each end for CFS consolidation and deconsolidation. It is the right choice for cargo below 15 CBM, test shipments, and regular small-volume orders. Above 15 CBM, FCL usually becomes more cost-effective even if the container is not fully loaded.

How long does ocean freight take?

Ocean freight transit times vary significantly by trade lane. Asia to North Europe currently takes 35-40 days via Cape of Good Hope (normally 25-30 days via Suez). Asia to US West Coast takes 14-18 days. Asia to US East Coast via Panama takes 28-35 days. Intra-Asia shipments take 3-12 days. These are port-to-port sailing times only. Door-to-door transit including pre-carriage, export clearance, and destination delivery typically adds 7-14 days.

How are ocean freight rates calculated?

Ocean freight rates combine several components: the base freight rate (per TEU or FEU, varying by trade lane and market conditions), Terminal Handling Charges at origin and destination, Bunker Adjustment Factor (BAF) for fuel, seasonal surcharges (PSS), and additional charges depending on cargo type and destination. Total all-in rates on major trade lanes in 2025 range from approximately $1,800-$4,000 per FEU for Asia-Europe and $1,500-$3,500 for Asia-US West Coast, based on Freightos Baltic Index data.

What is a GRI in shipping?

GRI stands for General Rate Increase. A GRI is a carrier announcement raising base freight rates on a specific trade lane, typically with 30 days' notice. GRIs are a mechanism carriers use to increase revenue during periods of high demand or tight capacity. Whether a GRI actually takes effect depends on market conditions — when capacity is abundant and demand is soft, the market typically rejects GRIs and rates fall or stay flat regardless of carrier announcements.

What is a blank sailing?

A blank sailing is the cancellation of a scheduled vessel departure by a carrier or alliance, removing that vessel's capacity from a trade lane for that week. Carriers use blank sailings to manage effective supply during periods of low demand, reducing available container space and supporting freight rates. The Drewry Cancelled Sailings Tracker publishes advance notice of upcoming blank sailings by trade lane, giving cargo owners early warning to rebook on alternative services.

What is a carrier alliance and how does it affect my shipment?

A carrier alliance is a commercial cooperation arrangement between shipping lines to share vessel capacity on major trade lanes. The three current alliances are Gemini (Maersk + Hapag-Lloyd), Premier Alliance (ONE, HMM, Yang Ming), and Ocean Alliance (CMA CGM, COSCO, Evergreen). Alliance membership means your cargo booked with one carrier may physically move on a partner carrier's vessel. This affects which ports are called, schedule frequency, and OTP. Alliance capacity management through blank sailings also directly influences the spot rate levels you see.

What is the Freightos Baltic Index (FBX)?

The Freightos Baltic Index (FBX) is a container freight rate benchmark published jointly by Freightos and the Baltic Exchange. It covers 12 major global trade lanes and is published daily and weekly. The FBX is used by shippers to benchmark their contract rates against spot market levels, by carriers to reference transparent market pricing, and by financial instruments (futures) as a settlement index. The Drewry World Container Index (WCI) and Xeneta Shipping Index (XSI) serve similar functions across different data methodologies.

How does the Red Sea situation affect ocean freight in 2025?

Since December 2023, Houthi attacks on commercial vessels in the Bab el-Mandeb strait have caused most Asia-Europe container carriers to reroute around the Cape of Good Hope. This adds 7-10 days to transit times and absorbs significant vessel capacity — effectively tightening supply on Asia-Europe lanes. As of mid-2026, Cape routing remains the standard for most services. When carriers begin returning to the Suez Canal route, a large block of effective capacity will be released, likely causing a period of congestion at European hub ports and downward pressure on Asia-Europe rates.

What is CII and how does it affect ocean freight costs?

CII stands for Carbon Intensity Indicator, an IMO framework rating vessels from A to E based on their operational carbon intensity (grams of CO2 per tonne-nautical mile). Vessels rated D or E for three consecutive years face operational restrictions. For shippers, CII has two practical implications: first, carriers are retiring older, less efficient vessels earlier, slightly reducing effective capacity; second, some carriers charge efficiency-based surcharges or structure their contracts around vessel CII ratings. The EU ETS, launched in 2024, adds a more direct carbon cost on EU-trade invoices.

What is detention and demurrage in ocean freight?

Detention and demurrage are two related but distinct container usage charges. Demurrage is charged when a container remains inside the terminal beyond the carrier's free time period (typically 3-7 days). Detention is charged when an empty container is not returned to the carrier's depot within the free time window after unpacking. Both charges escalate daily — typically $100-$400 per container per day depending on the carrier and trade lane — and represent one of the most common sources of unexpected cost in ocean freight. Careful shipment planning, strong terminal relationships, and confirmed delivery appointments are the main mitigations.
