Sea freight transit times from China: what the clock is made of

Written by the getchinasourcing team  ·  Last updated 14 September 2026

Your forwarder says eighteen days. The market data says thirty-seven. Both are right, and the gap between them is where import schedules go wrong.

Eighteen days is port to port: the vessel leaves Ningbo, the vessel arrives at Long Beach. Thirty-seven is the whole chain from the moment your cargo is ready at the factory to the moment the container leaves the destination port. Neither number is dishonest. They simply measure different journeys, and if you plan a launch date against the first one you will be nineteen days short.

So rather than give you a transit time, this page gives you the clock it is made of. Transit times move with the season, the lane and the state of the Red Sea. The structure does not.

The six segments

These are the ranges we plan around when we schedule an order. They are our working assumptions, not universal constants, and we publish them for the same reason we publish our cost coefficients: a planning number you cannot inspect is not much use to you.

Add those up and the arithmetic explains the gap on its own. A twenty-day sailing sits inside a five to seven week door-to-door chain, and four of the six segments have nothing to do with the ship.

Port to port, by lane

These are the sailing legs only. Read them as the fourth row of the table above, not as an answer to when your goods arrive.

What the market is actually running at

Flexport publishes an Ocean Timeliness Indicator that measures something much closer to reality than a sailing schedule: the time from cargo being ready at origin to the container leaving the destination port. In the week to 10 August 2026 it read:

• China to US West Coast: 37.6 days. Against a 14 to 21 day sailing.
• China to US East Coast: 66.1 days. Against a 28 to 38 day sailing.
• China to North Europe: 57.6 days. Against a 30 to 46 day sailing depending on routing.

Those readings move every week, which is exactly the point. We are citing them with a date rather than folding them into a sentence that will quietly become false. If you are planning a shipment now, check the current reading rather than trusting this paragraph.

Note what the indicator does not include: your last mile. Even the longer number stops when the container leaves the destination port, so add the final segment yourself.

Asia to Europe has two different answers right now

Since late 2023 most Asia to Europe services diverted away from the Red Sea and around the Cape of Good Hope, adding roughly ten to fourteen days each way. During 2026 that has begun to partially reverse: several carriers have restored Suez routings on selected services, while others continue to run their main loops around the Cape. Canal traffic has recovered substantially from its low point but remains well below pre-crisis levels.

The practical consequence for a buyer is not which route is better. It is that on this lane the routing is now a question you have to ask. Two quotes for the same lane, the same week, can differ by a fortnight depending on which service the cargo is booked onto, and a quotation that gives you a transit time without telling you the routing has left out the most important variable.

Ask the forwarder which service and which routing. If the answer is vague, treat the longer figure as your planning assumption.

Why LCL adds a week at each end

Consolidated cargo sails on the same vessel as a full container, so the ocean leg is identical. The difference is entirely at the ends. Your cargo waits at the origin container freight station to be consolidated with other shippers' goods, and waits again at destination to be deconsolidated before it can be released. Plan on three to seven days total, weighted toward the destination end.

This matters when you are choosing a shipping mode, because it changes the comparison: consolidated freight is not simply the cheaper option, it is the cheaper and slower option. We work through the cost side of that decision, with our actual rates published, in LCL or FCL, and how to work out your own break-even.

What actually makes you late

In our experience the delays that hurt are rarely the ocean leg. In rough order of how often they bite:

1. The factory finishes late. By far the most common cause, and the one furthest upstream, so it pushes everything else. It is also the one an inspection booked before the cut-off will expose while you still have options.
2. Rolled cargo. The booking exists but the container does not make the vessel, usually in peak season. You lose a week and nobody tells you until it has happened.
3. Missing the terminal cut-off. Cargo arrives at the port after the documentation or gate deadline and waits for the next sailing.
4. Document errors at destination. A wrong description, a missing certificate, an inconsistency between the invoice and the packing list. Customs holds are slow to clear and entirely preventable.
5. Chinese New Year. Not a delay so much as a cliff. Factories stop for weeks and the port system congests before and after. We cover the planning calendar in production planning around Chinese New Year.

There is also a structural reason transit times are longer than importers remember from a decade ago. Carriers have had both commercial and regulatory reason to sail slower since the IMO brought in carbon intensity rules for existing ships in 2023. Slower steaming saves fuel and improves a vessel rating. It also costs you days.

Building a date you can commit to

Work backwards from the date you need the goods, not forwards from the date you place the order. The forward calculation quietly assumes every segment behaves, and they do not all behave at once.

1. Start at your required in-warehouse date.
2. Subtract the last mile and the destination segment. For a US or EU port that is a week to ten days before you can touch the goods.
3. Subtract the sailing for the lane and routing you have actually been quoted, not the fastest one on the lane.
4. Subtract the origin segment and the booking window, which is where peak season hurts most.
5. Subtract the production lead time, then add a buffer for it, because this is the segment that slips.
6. The date you land on is your order date. If it has already passed, the honest conclusion is that this shipment needs to move by air or the launch date needs to move.

That last step is the useful one. Most schedule failures are not caused by a bad forwarder; they are caused by an order placed three weeks after the date the arithmetic required, with everyone downstream hoping the freight will make it up. Freight never makes it up.

When the schedule has already slipped

Knowing how the clock is built is only useful if it tells you what to do when you are already behind. These are the recovery options in the order we would try them, cheapest per day recovered first. Most buyers jump straight to the last two.

1. Split the shipment. Send by air only the quantity you need to hit the date — the launch stock, the quantity already sold, the samples a customer is waiting on — and let the balance follow by sea. You pay the air premium on a fraction of the order instead of all of it, and in most cases this recovers the date at a tenth of the cost of airing everything.
2. Move to a faster service on the same lane. Not all sailings on a lane run at the same speed. Expedited transpacific services exist and are materially quicker than standard loops, at a premium well below air. Worth asking for by name rather than waiting to be offered.
3. Change the destination port. An all-water service to the East Coast and a West Coast discharge with inland transport are genuinely different clocks, and which one wins depends on where your warehouse is. If your cargo is booked to the slower of the two and your warehouse is reachable either way, the routing is worth re-running.
4. Air the whole shipment. Sometimes correct, especially for dense high value goods where the multiple against sea freight is smallest. For bulky low value cargo it can cost more than the goods.
5. Move the date. The option nobody puts on the list. If the arithmetic says the date is not reachable, the cheapest response is usually to tell whoever is downstream now rather than to spend heavily and arrive late anyway.

One thing that is not on the list: pressing the factory to ship before the goods are right. A shipment that sails on time and fails inspection at your warehouse has not saved you any days at all — it has moved the problem to the most expensive place to discover it.

What we do about it on your behalf

We book the inspection before the terminal cut-off rather than after it, so that a production problem surfaces while there is still a decision to make. We tell you the routing, not just the transit time, and we quote on terms you can audit rather than a single delivered number — the reasoning is in DDP or FOB, and who is the importer of record. We check documents against the commercial invoice before the container sails, because a customs hold at destination costs more days than anything we can save at origin. And when a schedule is genuinely not achievable, we say so at the quotation stage rather than at the cut-off.

The freight itself is arranged through our freight and customs service, and the cost side of the same decision is modelled in the landed cost calculator, where every rate we apply is published.
