Container freight is one of the few costs in importing where the market price is published weekly and free to read. Most importers never look, then wonder whether the quote in front of them is fair. This article is for companies booking FCL from China on a regular cadence, and explains what the main indices measure, where they diverge from the number on your invoice, and how to use them in an actual negotiation.
The four indices worth knowing
- SCFI — Shanghai Containerized Freight Index. Published by the Shanghai Shipping Exchange, weekly. Spot rates for exports out of Shanghai across a basket of trade lanes. Closest to the origin you are buying from, and the most quoted in Asia.
- CCFI — China Containerized Freight Index. Same publisher, broader: multiple Chinese ports, and it blends contract with spot, so it moves more slowly and smoothly than SCFI.
- WCI — Drewry World Container Index. Weekly composite of spot rates across major East–West lanes, widely used in Europe and in the trade press.
- FBX — Freightos Baltic Index. Daily, built from transactional data, which makes it the fastest to reflect a turning market.
Xeneta's XSI sits alongside these and leans toward contracted rather than spot rates, which makes it useful if you buy on annual contracts rather than shipment by shipment.
Why the index never matches your quote
This is the most common source of confusion, and none of it means you are being overcharged:
- Indices are spot rates. If you buy on a contract, your rate is deliberately smoother than the index — better when spot spikes, worse when spot collapses.
- Coverage differs. Most indices quote port-to-port ocean freight. Your invoice includes origin and destination terminal handling, documentation, security fees and local charges, which the index does not — the full anatomy is in what makes up a container rate.
- They are averages of a lane, not a price for your box. A 40HC of dense cargo to a secondary port on a small carrier is not the lane average.
- They lag. Weekly indices report what already happened. In a fast-moving week, FBX moves before SCFI does.
- Your volume matters. An importer shipping forty containers a year and one shipping four hundred are not offered the same number, whatever the index says.
What they are genuinely useful for
- Direction, not level. The single most valuable read is whether the market is rising or falling, and how fast. That decides whether to book now or wait a week.
- Sanity-checking a quote. If the index has fallen 20% over six weeks and your forwarder's rate has not moved, that is a conversation worth having.
- Timing a contract. Signing an annual rate at the top of a spike locks in the top of a spike. Indices are the only public way to know where you are in the cycle.
- Budgeting. For next-season landed cost modelling, an index trend beats a single quote — see landed cost of a China import.
- Explaining a rate increase internally. A published index is a neutral third party in a conversation with your own finance team.
Reading the seasonal shape
Rates are not random. They follow a repeating annual pattern, which the indices make visible:
- Pre-Chinese New Year surge — everyone ships before the factories close; rates climb and space tightens, per the Chinese New Year 2027 calendar.
- Post-holiday slump — demand collapses for several weeks while factories restart.
- Peak season, roughly August to October — Western holiday stock moves; peak season surcharges appear.
- Golden Week compression — a hard stop in early October, covered in China's holidays and production shutdowns.
Layered on top of that seasonality are structural shocks — capacity withdrawn, routings extended, ports congested. The Asia–Europe lane has been shaped by exactly such a shock, described in Red Sea routing and Asia–Europe transit.
How to use an index in a negotiation
- Quote the lane and the week, not a general impression: "WCI Shanghai–Rotterdam is down X% over four weeks."
- Ask for the breakdown, not the total. Ocean freight is the part the index speaks to; if the total has not moved, find out which surcharge absorbed the fall.
- Ask what happens if the market moves after booking. Rate validity periods and GRI pass-through are negotiable terms, not laws of nature.
- Do not chase the last dollar in a rising market. When rates climb, space is the scarce good, not price — a cheap booking that gets rolled twice costs more than an expensive one that sails.
That last point is the one experienced importers weigh most heavily: in a tight market, reliability of loading beats a lower number, especially against a fixed retail season.
The limits worth respecting
An index cannot tell you whether your particular forwarder is competitive on your particular lane at your particular volume, and it says nothing at all about the costs that actually wreck budgets — demurrage, detention, storage and rework, covered in demurrage and detention. Treat indices as a weather report: essential for deciding when to sail, useless for telling you whether your ship is sound.
The freight market publishes its price every week, and almost nobody in the import chain reads it except the people selling the freight. That asymmetry is the entire reason quotes go unquestioned for months after the market has turned.
Booking against the market rather than against a single quote
We track lane rates and seasonality, book ahead of predictable crunches rather than into them, and hold forwarders to the movement of the market rather than to last quarter's number. Seven years and 3,500+ deliveries of doing this — real projects are in our case studies.
