QUICK ANSWER Typical shipping time from China to US ports runs 13 to 21 days port to port to the West Coast, 28 to 35 days to the East Coast via the Panama Canal, and 30 to 37 days to the Gulf. The fastest routings are direct sailings into Los Angeles, Long Beach, or Seattle; the fastest way to reach the Midwest is a West Coast port plus rail. Door to door, add two to three weeks around any of these numbers.
The shipping time from China to US warehouses is really two numbers: the vessel's port-to-port transit, which is set by geography and routing, and everything around it, which is not. Importers who plan on the first number alone run out of stock. This guide gives the full port table, the origin-port differences, the routing choices that move the total by weeks, and the seasonal pattern of the lane. We re-check the tables against live sailing schedules quarterly.
Port-to-port times to every US gateway
These are typical port-to-port transits from the main China base ports (Shanghai and Ningbo) on the China to USA lane, for the fastest commonly available service to each gateway. Ports marked "via connection" see few direct China calls, so most cargo arrives via another US port or a transshipment hub.
Typical port-to-port transit, China to US gateways
| US gateway | Coast | Typical days | Service note |
|---|---|---|---|
| Los Angeles / Long Beach | West | 14 to 17 | Direct, most sailings on the lane |
| Seattle / Tacoma | West | 13 to 16 | Direct, shortest crossing |
| Oakland | West | 16 to 19 | Direct, often after an LA call |
| Portland | West | 17 to 21 | Limited calls, often via Seattle |
| New York / New Jersey | East | 28 to 32 | Direct all-water via Panama |
| Boston | East | 30 to 34 | Mostly via NY/NJ connection |
| Baltimore | East | 31 to 35 | All-water, fewer direct calls |
| Norfolk | East | 29 to 33 | Direct all-water |
| Charleston | East | 29 to 33 | Direct all-water |
| Savannah | East | 28 to 33 | Direct all-water, biggest Southeast gateway |
| Jacksonville | East | 30 to 35 | Mostly via connection |
| Miami | East | 30 to 35 | All-water, some via transshipment |
| Houston | Gulf | 30 to 36 | All-water via Panama |
| New Orleans | Gulf | 32 to 37 | Fewer direct calls |
Treat the ranges as planning brackets to verify against live schedules at booking, because carriers adjust rotations through the year. The pattern to remember: the West Coast is two weeks, the East Coast is four, the Gulf is closer to five.
How the China origin port changes the math
The US port sets most of the transit; the China port fine-tunes it. Shanghai and Ningbo are the baseline, with the deepest schedule choice on the lane. South China ports run about even with the baseline to the West Coast but offer slightly fewer direct East Coast strings. North China adds sailing days before the ocean crossing even starts.
Origin adjustments vs the Shanghai/Ningbo baseline
| China origin | Adjustment | Note |
|---|---|---|
| Shanghai / Ningbo | Baseline | Most sailings, most direct options |
| Shenzhen (Yantian) / Guangzhou | 0 to +1 day | Strong direct West Coast coverage |
| Xiamen | +1 to +2 days | Good coverage, fewer strings |
| Qingdao | +2 to +3 days | North China, added coastal leg |
| Hong Kong | 0 to +1 day | Functions as a South China gateway |
The practical use of this table is supplier planning: a Qingdao supplier and a Yantian supplier quoted "the same" transit are three to four days apart in reality, and on a tight restock that difference is the buffer.
Direct sailing or transshipment
A direct service loads in China and discharges at the US port with no vessel change. A transshipment service moves the container through a hub, Busan, Kaohsiung, or a Southeast Asian port, where it waits for a connecting vessel. Transshipment routings are often cheaper and reach ports direct strings skip, but they add three to ten days, and they add a failure mode: a missed connection at the hub costs a week on its own. A quote will not always volunteer which type it is, so ask; the schedule line showing one vessel or two tells you the answer.
Why the East Coast takes twice as long
East Coast services from China sail the Pacific and then the Panama Canal, roughly doubling the water time against a West Coast direct call. For East Coast and Midwest destinations there is a second routing: discharge at a West Coast port and move inland by rail. An IPI (interior point intermodal) routing through Los Angeles or Long Beach reaches Chicago, Memphis, or Dallas in roughly 20 to 25 days total, versus roughly 28 to 37 all-water to the East Coast or Gulf, at a higher cost per container. Neither answer is universally right: all-water wins on cost and touch count, the rail routing wins on speed. The right choice depends on your warehouse location and what a stockout day costs you.
Port-to-port vs door-to-door
The vessel's transit is the middle of the journey, not the journey. In front of it sit supplier handoff, origin trucking, export clearance, and, for consolidated cargo, the wait to fill a shared container. Behind it sit US customs release, terminal pickup, and delivery. Together they add roughly two to three weeks to the port-to-port figure for FCL, and more for LCL, which waits at both ends for consolidation and deconsolidation. A 15-day Shanghai to Los Angeles transit is a five-week door-to-door plan, and quoting it any shorter just moves the surprise to the end.
What makes transit slip
The schedule is a plan, not a contract. Blank sailings remove a vessel from the rotation and push cargo a week. Transshipment connections get missed. Port congestion queues vessels at anchor in bad stretches. Weather rerouting, peak-season volume, and a customs hold or exam at destination each add their own days. None of these is exotic; every importer meets all of them eventually, which is why inventory plans are built on the range plus a buffer, not the best case.
TAKEAWAY Plan replenishment on the slow end of the range plus a week, not the fast end. The difference between a 15-day and a 20-day West Coast transit is invisible in the freight cost and decisive in a stockout. Variance, not the average, is what empties a warehouse shelf.
Seasonality: when the lane runs slow
The transpacific has a calendar. January to April is the quiet stretch, except the weeks around Chinese New Year, when the pre-holiday rush squeezes space and then the factories close. After CNY, carriers blank sailings against the demand dip, which can stretch schedules for several weeks. August through October is peak season: space tightens, rollings increase, and the same booking takes longer to confirm. Cargo that can choose its month ships fastest, and cheapest, in the quiet stretch; cargo that cannot should carry a bigger buffer in peak months.
Picking the port for your inventory math
The port choice is an inventory decision wearing a freight costume. Warehouses in the western half of the US take a West Coast port and short drayage. Midwest destinations usually win with West Coast plus rail. East Coast warehouses weigh all-water into NY/NJ, Norfolk, Charleston, or Savannah against the faster, pricier rail routing. The Southeast has three gateways of its own, and Gulf importers take Houston all-water and accept the longest transit on the lane. Whichever port you choose, the free-time clock at that terminal starts the same way, so the demurrage math belongs in the same decision.
How Platton plans transit with you
A transit table is generic; your restock date is not. Platton quotes against real sailings, not averages.
Quoted on a named sailing
Your quote carries an actual vessel, cutoff, and ETA, so the transit you plan on is a schedule, not a range from a table.
Direct or transshipment, stated plainly
The quote says whether the service is direct or connects at a hub, because a cheaper transshipment rate that risks a week at a hub port is a different product, not the same one cheaper.
Milestones tracked against the plan
Departure, transshipment, arrival, and release show in real-time tracking, so a slipping ETA is flagged while there is still time to react, including switching a critical part of the order to air freight.
The buffer built into the plan
Restock plans are set against the slow end of the lane's range, so an ordinary slip lands inside the plan instead of inside a stockout.

Common Questions About China to US Transit Times
Which US port has the shortest transit time from China?
Seattle and Tacoma, at 13 to 16 days on direct services, with Los Angeles and Long Beach a day or two behind. Seattle wins on the water because it is the shortest great-circle crossing; LA/LB usually wins on total time to market for Southern California and inland distribution, because it has more sailings to choose from and denser drayage and rail connections behind the port.
Is all-water to the East Coast faster than West Coast plus rail?
No, it is slower but cheaper. All-water via Panama reaches the East Coast in 28 to 35 days; a West Coast discharge with rail inland reaches the Midwest in roughly 20 to 25, at a premium per container. The rail routing buys one to two weeks. Whether that is worth paying for depends on inventory pressure, which is why the same importer often uses both in different months.
How much time does transshipment add from China to the US?
Plan on three to ten days over a comparable direct service, depending on the hub and the connection. The bigger issue is variance: a missed connection at Busan or Kaohsiung adds a full week, and no one refunds it. Transshipment is a fair trade for a lower rate on non-urgent cargo, and the wrong routing for anything with a hard delivery date; the difference lives in the on-time percentage, so a quote should name the vessel string, not just the days.
Why do carriers blank sailings, and what does it do to my ETA?
A blank sailing is a scheduled departure the carrier cancels, usually to tighten space when demand dips, most reliably in the weeks after Chinese New Year. Cargo booked on a blanked vessel rolls to the next sailing, typically adding about a week. You cannot prevent it; you can book on services with more frequent departures, where the next vessel is days away instead of a week or more.
How far ahead of a restock date should I book from China?
Work backward: door-to-door transit at the slow end of the range, plus a week of buffer, plus your supplier's production time. Counted from the cargo-ready date, that means booking roughly six to seven weeks before the goods must be on the shelf for a West Coast routing, and nine to ten for all-water East Coast, with production time added on top. Booking earlier than that costs nothing; booking later converts ordinary schedule noise into an air freight bill.
