A freight rate comparison platform answers the wrong question well. It tells you which number is lowest today, not which number will survive to the invoice, and on China lanes the gap between those two is where importers lose margin. These ten were ranked on how much of the rate is pinned.
Why a Freight Rate Comparison Platform Quotes Numbers You Cannot Compare
Put the same 40HQ from Ningbo to Los Angeles into five comparison tools and you will get five numbers that look like a market. They are not. One is port to port, one includes origin handling, one is built on a rate that expired on the 14th, one assumes a merchant haulage leg you do not want, and one has quietly excluded the peak season surcharge that will be applied at booking.
The numbers are real. The comparison is not, because comparison requires that two quotes share a basis, and most platforms never state theirs. A rate is not a price. It is a price plus a validity window plus a surcharge set plus a cargo basis plus a port pair plus an owner of the destination documents.
Platforms that make you state the basis produce fewer quotes and better decisions. Platforms optimised for a fast headline number produce the opposite. That difference is what the ranking measures.
What a Rate Actually Contains
Six variables decide whether two quotes can be compared at all. Miss any one and the cheaper number is not cheaper.
| Variable | What it changes | How it is usually hidden |
|---|---|---|
| Validity window | Whether the rate still exists when you book | Shown as "from" pricing with no expiry date |
| Surcharge set | Adds 15% to 40% to the ocean line | Named in a separate tariff, applied at booking |
| Cargo basis | Weight or measure, whichever is greater | Quote assumes volume and ignores density |
| Port pair precision | Door, port or CY, at both ends | "China to USA" instead of named terminals |
| Equipment | 20GP, 40GP, 40HQ, reefer, SOC | Cheapest box quoted, your cargo needs another |
| Document ownership | Who files export and import formalities | Assumed to be included; it is not |
A quote that pins all six is a contract. A quote that pins two is an advertisement. The ten platforms below sit at different points on that line, and the ranking reflects that rather than traffic or funding.
How These Ten Were Ranked
Five criteria, weighted for an importer buying China-origin freight rather than a forwarder buying capacity.
| Criterion | Weight | What was checked publicly |
|---|---|---|
| How much of the quote is pinned | 30% | Whether validity, surcharges and basis are disclosed before you commit |
| China-origin coverage | 20% | Named Chinese ports and inland origins, not "Asia" |
| Ability to act on the number | 20% | Book, or hand off to an operator, without re-quoting elsewhere |
| Comparison breadth | 15% | Multiple carriers or forwarders on one lane rather than one house rate |
| Data usability | 15% | Export, API, historical series, or a benchmark you can cite internally |
A single-forwarder platform scores lower on breadth even when its rates are excellent, because the product it sells is its own service, not a market view. That is a legitimate product. It is simply not a comparison.
The Ten at a Glance
Grouped by what the platform is actually for, ordered by usefulness to a first-time China importer.
| # | Platform | Type | Published scope | Best for |
|---|---|---|---|---|
| 1 | Freightos | Marketplace plus index | Ocean and air quoting, forwarder booking network, published index | Seeing a market range before you negotiate |
| 2 | SeaRates | Calculator and marketplace | Freight calculator, schedules, load calculator, route tools | Sanity-checking a quote in ten minutes |
| 3 | iContainers | Digital forwarder | Instant FCL and LCL quotes with online booking | One quote, one operator, no handover |
| 4 | Flexport | Digital forwarder | Quote, book and operate with a shared dashboard | Buyers who want software around the shipment |
| 5 | cargo.one | Air rate distribution | Airline and consolidator rates for forwarders | Forwarders sourcing air capacity |
| 6 | CargoAi | Air quoting API | Air cargo pricing and booking integration | Teams that price air inside their own system |
| 7 | Shippabo | Mid-market platform | Quote, document and track in one workflow | Small import programmes with repeat lanes |
| 8 | Xeneta | Benchmark data | Contract versus spot rate indices by lane | Proving a renewal price is too high |
| 9 | Drewry | Index publisher | Weekly container index on major headhaul lanes | A defensible number in a board paper |
| 10 | CargoRate | China-side aggregator | Carrier e-commerce rates with monitoring and booking | Buyers with a Chinese forwarder account |
Marketplaces That Quote and Book
Four platforms that will produce a number and let you act on it. They differ in whether the number is a market or a house rate.
1. Freightos
Best for: establishing a market range before you open a negotiation.
Why it makes the list: Freightos runs a marketplace that returns live ocean and air quotes, and it also publishes an index that importers can cite when a forwarder claims the market moved. For a first-time buyer the combination is useful: the marketplace gives a transactable number, the index gives a reference point that does not depend on any single forwarder's mood.
Limitation: marketplace quotes are strongest as a range, not a contract. Validity is short, and the cheapest line is often port to port with destination charges excluded, so the number that looks 12% below your forwarder can end up above it once THC and delivery are added.
2. SeaRates
Best for: a fast, free sanity check on any lane, including the parts a quote usually omits.
Why it makes the list: the platform publishes a freight calculator, sailing schedules, a container load calculator and route and distance tools in one place. The load calculator is the underrated part: it tells you how many cartons fit before you ask for a rate, which prevents the common error of quoting a 40HQ for cargo that physically needs two 20GPs.
Limitation: calculator output is indicative. It is a good instrument for spotting a quote that is 40% off market, and a poor instrument for choosing between two quotes that are 5% apart.
3. iContainers
Best for: one number from one operator, bookable online without a second conversation.
Why it makes the list: instant FCL and LCL quotes with online booking and a named operations contact, which removes the handover that usually loses a week. For an importer shipping two or three containers a year, the value is not the lowest rate but the fact that the party quoting is the party executing.
Limitation: it is a forwarder, so you are comparing its buy rates with the market, not comparing the market with itself. Its service scope also decides what is possible; if you need a destination document filed by a specific party, that may fall outside the platform.
4. Flexport
Best for: buyers who want the shipment operated inside software rather than by email.
Why it makes the list: quoting, booking, documentation and tracking sit in one dashboard, and the platform publishes research on rate movements that is more useful than a bare quote. For an importer running several suppliers and a rolling replenishment calendar, the operational visibility is the product, and the rate is a component of it.
Limitation: it is a single forwarder with a technology layer. As a comparison tool it shows you one house's pricing, and moving away from the platform later means rebuilding your document history elsewhere.
Rate Infrastructure Built for Forwarders
These three are not aimed at importers, and that is exactly why they matter: the rates your forwarder shows you are increasingly sourced from them.
5. cargo.one
Best for: a forwarder or a buyer with an in-house logistics arm sourcing air capacity.
Why it makes the list: cargo.one distributes airline and consolidator air rates to forwarders with instant booking, which has compressed the time between a rate request and a confirmed allotment from days to minutes. If your forwarder uses it, your air quote is closer to the airline's own price than it was five years ago.
Limitation: access is B2B. A shipper without a forwarder account cannot use it directly, and the platform's value to you is indirect — it shows up as a faster, tighter air quote rather than as a tool you operate.
6. CargoAi
Best for: teams that want air pricing inside their own systems rather than on a website.
Why it makes the list: CargoAi exposes air cargo pricing and booking through an API-first model, which lets a forwarder or a large shipper embed live rates into a quotation tool or an ERP. For a company quoting its own customers, that changes the arithmetic: the rate is current at the moment of quoting rather than at the moment of the last email.
Limitation: air only, and integration work is on you. It is infrastructure, not a consumer product, so the total cost includes development time.
7. Shippabo
Best for: a small import programme with two or three repeat lanes.
Why it makes the list: the platform combines quoting, document management and tracking for mid-market shippers, which is the segment that usually falls between a spreadsheet and an enterprise TMS. Repeat lanes are where it earns its place: the second and third shipments reuse the same document set, so the operational saving is larger than the rate saving.
Limitation: the carrier and forwarder network is smaller than the large marketplaces, so on an unusual lane the quote may be a hand-built number rather than a live one.
Benchmarks and China-Side Aggregators
Three sources that do not sell you a shipment. Two sell you a number you can defend, one sells you the carrier's own rate.
8. Xeneta
Best for: proving that a renewal quote is above the market before you sign it.
Why it makes the list: Xeneta benchmarks contract rates against spot and historical data by lane, built from contributed shipping data. For an importer whose forwarder says "rates went up 30% this quarter", a lane-level index is the difference between accepting the claim and testing it.
Limitation: it is a data subscription, not a booking tool, and the value depends on whether your exact lane and equipment type are covered. Smaller ports and non-standard equipment can fall outside the sample.
9. Drewry
Best for: a single citable number for a board paper or a supplier negotiation.
Why it makes the list: the World Container Index is published weekly on major headhaul lanes and is quoted widely enough that a counterparty will recognise it. When a Chinese supplier proposes a CIF price built on "current freight", a published index is the simplest way to check the freight component.
Limitation: an index is a composite, not your shipment. It covers a defined set of lanes and box types, so it can move differently from the rate you actually pay, especially on secondary ports or LCL.
10. CargoRate
Best for: buyers who already work with a Chinese forwarder and want the carrier's own e-commerce rate.
Why it makes the list: the platform aggregates rates from carrier online booking channels, with monitoring, price alerts and booking, which puts the shipping line's own spot price in front of a Chinese-speaking operator. For an importer whose forwarder is in Ningbo or Shenzhen, this is often the number the forwarder is working from.
Limitation: the interface and workflow are built for the Chinese market, and access generally assumes a forwarder relationship. It also reflects carrier e-commerce rates, which are not available on every lane or for every commodity.
The Six Variables, Pinned One by One
The practical use of a comparison platform is not to find the lowest number. It is to force each quote onto the same basis before you compare.
| Variable | What to ask | What a good answer looks like |
|---|---|---|
| Validity | Until which date is this rate firm? | A date, plus what happens if the sailing rolls past it |
| Surcharges | Which surcharges are included and which are open? | A named list with amounts, or a link to the tariff |
| Basis | Is this per container, per W/M, or per chargeable kilo? | The basis stated, plus the minimum charge |
| Port pair | Which terminal at origin and destination? | Named ports and whether haulage is included |
| Equipment | Which box type, and what is the free time? | Box type, free days, detention rate after |
| Documents | Who files export declaration and import entry? | A named party on each side, with the fee |
Two quotes that answer all six can be compared on price. Two that answer three cannot be compared at all, no matter how close the numbers look on screen.
Where Comparison Breaks: Surcharges and Validity
The ocean line is the smallest part of a China-origin invoice on many lanes. The gap between a quoted number and the final invoice is mostly surcharges and time.
| Line | How it behaves | Why a comparison misses it |
|---|---|---|
| Ocean freight | Moves weekly on spot lanes | Quoted number may be a month old |
| Peak season surcharge | Applied per container when the carrier declares it | Not in the platform quote until the booking date |
| Origin THC and documentation | Fixed per container, varies by terminal | Often excluded from "port to port" quotes |
| Destination THC and delivery order | Fixed per container, charged in local currency | Almost always excluded, and the largest surprise |
| Demurrage and detention | Daily after free time | Not priced at all until it happens |
| Currency and payment fees | 1% to 3% on cross-border payment | Invisible at quoting stage |
A worked illustration. A 40HQ Ningbo to Los Angeles is quoted at USD 2,150 with 14-day validity. By booking the carrier applies a USD 300 peak season surcharge, origin handling adds USD 180, destination handling and delivery order add USD 430, documentation adds USD 60, and payment fees take another USD 60. The invoice lands near USD 3,180, which is 48% above the number that won the comparison.
None of those lines is fraudulent. They were simply not in the quote, and the platform that showed USD 2,150 did not claim they were.
Reading a Quote Against the Invoice
The useful habit is to compare like with like before booking, not after. Four checks do most of the work.
- Convert every quote to a landed number for one container. Add origin handling, ocean, destination handling, delivery to door and duty where applicable. Compare the totals, never the ocean lines.
- Check the basis on LCL. Freight is charged per revenue ton, the greater of cubic metres and metric tonnes. Three pallets at 2.4 m3 and 2,900 kg are charged as 2.9 revenue tons, not 2.4.
- Check air chargeable weight. Volumetric weight at the standard 1:6000 ratio turns 0.8 m3 into about 133 kg, so a light bulky carton pays for space it does not weigh.
- Date every rate you keep. A rate without a validity date is a historical record, not a quote, and using one in a supplier negotiation is how a CIF price gets built on last quarter's market.
Editor's Pick: A Desk That Turns a Rate Into a Loading Plan
This is not a third-party ranking, and none of the ten platforms is a client. The pick is about what to do with the number once you have it.
A comparison platform ends at a price. Freight does not: the price has to become a loading plan, a document set and a delivery appointment, and that translation is where the surcharge surprises and the weight problems live. A buying desk that consolidates several suppliers into one container can fix the basis before the rate is even requested, because it knows the carton count, the measured volume and the actual weight.
At SilkRoadSource the order consolidation service is built around that sequence — goods received, measured and merged before a rate is booked — and shipping support takes over the lane and document questions once the container is planned. The reason this beats a comparison platform for a mixed order is simple: you cannot compare rates for a shipment whose volume you have not measured.
Choose another agent if you ship one product from one factory in full containers on a fixed monthly lane. At that volume a direct carrier contract plus a rate index is cheaper and faster than any consolidation step, and paying a desk to merge nothing is a cost without a return.
The Five-Question Test Before You Trust a Quote
Ask these of the platform, or of the forwarder behind it.
- What is the validity date of this rate, and which surcharges are open?
- Is this price door to door, port to port, or CY to CY at each end?
- What is the chargeable basis for my cargo, and what is the minimum charge?
- Who files the export declaration and the import entry, and what do they charge?
- What are the free days at destination, and the detention rate after them?
A quote that survives all five is comparable. A quote that survives two is a starting point for a conversation, not a decision.
Frequently Asked Questions
Five questions importers ask after the first comparison produces five different numbers.
Are freight rate comparison platforms accurate for China lanes?
They are accurate about the ocean line and incomplete about everything else. Platform quotes are usually firm for a short window on the ocean component, while origin handling, destination handling, peak season surcharges and detention sit outside the number. Use them to establish a range, then convert the chosen quote to a landed total before committing.
Why is my forwarder's rate higher than the platform quote?
Usually because the two numbers are not the same product. A platform quote is often port to port with surcharges excluded, while a forwarder quote may include origin handling, documentation and a delivery order fee. Compare landed totals for the same port pair and equipment type, and the gap normally narrows to a few percent.
Can I book directly on a comparison platform?
On marketplace and digital forwarder platforms, yes, and the booking is with that platform or its partner rather than with the carrier. On benchmark and index services, no: they publish data and do not transact. Check who the contracting party is before you pay, because that party decides who answers when cargo is rolled or damaged.
Is a freight index the same as a rate I can book?
No. An index is a published composite for a defined lane and box type, useful for testing a claim or building a supplier negotiation. Your bookable rate depends on the specific ports, equipment, commodity and date, and it can differ from the index by a wide margin on secondary lanes.
How often do China to US and China to Europe rates change?
Spot rates on headhaul lanes are repriced weekly and can move sharply around peak season and before major holidays, while contract rates are typically fixed for a quarter or a year. That is why a rate without a validity date should never be treated as a quote: on a spot lane it may already be wrong by the time you forward it.
The rate is only half the decision; the other half is whether the shipment the rate describes actually exists as a measured, merged, document-ready lot. Order consolidation at SilkRoadSource covers the measure-and-merge step that makes a quote comparable, shipping support covers the surcharge and lane questions, and the team can be reached through contact with your carton list and target port.
