How long shipping from China takes
No official source publishes a single transit time for shipping from China to the United States. Transit time (the elapsed time between the cargo leaving its origin and reaching its destination) is set for the ocean leg by each carrier's published service schedule, and the door-to-door total adds origin and destination stages that no schedule shows.
Port-to-port times change with service rotations, canal conditions, blank sailings and congestion. A day count is only meaningful when it names the carrier service, the port pair, the date of the schedule, and whether it is port-to-port or door-to-door. Current carrier schedules were not reviewed for this page, so it gives no day counts. It explains instead what sets the number and where the time goes.
The routes from China to the US
A shipping route here means the sequence of sea passage and canal transit a vessel service follows between Chinese and US ports. China–US ocean services follow three routes, consistent with the lane definitions UNCTAD uses in its Review of Maritime Transport 2025 (RMT 2025):
- Across the Pacific to the West Coast. Direct trans-Pacific services to Los Angeles, Long Beach, Oakland, Seattle and Tacoma. This is the shortest ocean leg.
- Eastbound via the Panama Canal to the East or Gulf Coast. All-water services that cross the Pacific and transit the Panama Canal to ports such as New York/New Jersey, Savannah or Houston. The sea leg is materially longer than the West Coast crossing.
- Westbound via the Suez Canal to the East Coast. Services that cross the Indian Ocean, transit the Suez Canal and cross the Atlantic. This route is also materially longer at sea, and it is the one most exposed to Red Sea disruption.
Cargo bound for the US interior adds a land leg: a West Coast port plus rail or truck, or an East Coast port plus truck. For an East Coast consignee, an all-water service avoids transcontinental rail, so the longer sea route is not automatically slower door to door. No official comparative statistic on that trade-off was found.
What lengthened transits in 2024 and 2025
UNCTAD's RMT 2025, published in September 2025, documents four pressures on voyage times.
Red Sea diversions around the Cape of Good Hope
UNCTAD reports that "the detour around the Cape of Good Hope added approximately 30 per cent to voyage lengths" on affected routes, contributing to an estimated 11% increase in container TEU-mile demand in 2024. Its 2025 base case "assumes continued Red Sea rerouting of container vessels throughout 2025." The figure comes from Clarksons Research and mainly describes the East Asia–Europe route; for US cargo it applies only to Suez-routed services to the East Coast. Whether major carriers had returned to the Suez route by October 2026 was not checked for this page.
Panama Canal restrictions
UNCTAD notes that Panama Canal "transit restrictions (until mid-2024)" added to longer ton-miles in 2024. The status of canal draft and transit limits in 2026 was not confirmed with the Panama Canal Authority.
Blank sailings
A blank sailing is a scheduled vessel departure that a carrier cancels. UNCTAD reports "over 80 blank sailings on the trans-Pacific route" in April 2025, after the 2 April 2025 US tariff announcements. A blank sailing usually pushes booked cargo onto the next available vessel, which on a weekly service can mean a week's delay.
Port-fee rerouting risk
When USTR's Section 301 fees on China-linked vessels were announced, UNCTAD observed that carriers could shift China-linked ships away from US trades, which "could also cause shipping costs and voyage times to increase." The fees took effect on 14 October 2025 and were suspended from 10 November 2025.
Why door-to-door takes longer than port-to-port
The ocean crossing a carrier publishes is one stage of many. A door-to-door transit timeline from a Chinese factory to a US warehouse runs through:
- production completion and any pre-shipment inspection;
- inland haulage from the factory to the port or to a container freight station (CFS, a warehouse where LCL cargo is consolidated);
- the container-yard or CFS cut-off, the deadline by which cargo must be delivered, usually days before sailing and earlier for LCL because the consolidator must pack the container;
- Chinese export customs clearance;
- waiting for the vessel, up to a week on a weekly service if a cut-off is missed, longer if a booking is rolled to a later sailing in a peak period;
- the port-to-port ocean transit;
- transshipment at an intermediate port, if the service is not direct;
- US discharge, terminal dwell and CBP release, plus deconsolidation at a CFS for LCL;
- rail to an inland ramp or drayage to the final address, subject to warehouse appointment availability.
Two US filings also gate the timeline. The Importer Security Filing must reach CBP no later than 24 hours before the cargo is laden at the Chinese port (19 CFR 149.2(b)), and a customs entry must be filed for release after arrival. CBP does not publish a standard clearance time, and no CBP statistic on average release times was found; examinations and holds vary by shipment.
Where the time is lost
Origin port handling is rarely the bottleneck. S&P Global data reported in RMT 2025 (Table IV.1) show the average time to move a container during a port call in 2024. For calls of 1,001–1,500 moves, Chinese ports averaged 1.3 minutes per container against 2.0 minutes in the United States, with a 25-economy average of 1.7. For calls of 3,001–4,000 moves the figures were 0.6 minutes in China and 1.3 in the United States. These measure crane productivity per call, not total port dwell or customs time, but they support a practical point: delays tend to accrue in cut-offs, sailings, destination dwell and inland legs rather than at Chinese berths.
The stages that most often add days are the ones an importer can plan around: a missed cut-off that costs a full sailing cycle, a rolled booking in a peak period, an LCL shipment waiting for consolidation, and US-side dwell before a truck or rail slot is available.
Common mistakes when estimating shipping time from China
- Quoting the vessel's port-to-port time as the delivery date. Door-to-door adds origin cut-offs, export clearance, destination dwell, customs and inland legs.
- Ignoring the vessel cut-off. Missing it by a day can add a full weekly sailing cycle.
- Treating LCL as the same speed as FCL. LCL adds consolidation at origin and deconsolidation at destination.
- Assuming East Coast all-water is always slower. For East Coast consignees it avoids transcontinental rail; the answer depends on the final destination.
- Forgetting Chinese New Year and Golden Week. Back-planning from a launch date must account for factory closures around China's public holidays.
- Accepting a day count without asking what it covers. A forwarder's quoted transit time may be port-to-port or door-to-door; ask which, and which service and port pair it refers to.

Frequently asked questions
How long does sea freight from China to the US take?
There is no official figure; the time depends on the carrier service, the port pair and the route. Port-to-port times come from each carrier's published schedule, and door-to-door adds factory-to-port haulage, cut-offs, export clearance, US customs release and inland delivery. Any day count should name the service, the date of the schedule and whether it is port-to-port.
Why is shipping to the US East Coast slower?
The ocean leg is longer, because East Coast all-water services pass through the Panama Canal or the Suez Canal instead of crossing the Pacific directly to the West Coast. UNCTAD reports that diversions around the Cape of Good Hope added about 30% to voyage lengths on affected routes, which applies to Suez-routed services.
Why did my shipment from China take longer than quoted?
Common causes are blank sailings, congestion, rolled bookings and rerouting. UNCTAD recorded more than 80 blank sailings on the trans-Pacific route in April 2025 alone, after US tariff announcements; each one pushes cargo to a later vessel. A missed cut-off at origin can add a full weekly sailing cycle.
Is air freight always faster than sea freight door to door?
Air freight is generally faster in transit, but the same handling, export clearance and US customs stages still apply, so the door-to-door gain is smaller than the flight time suggests. No official source comparing air and ocean door-to-door times from China was found, so any comparison should rest on a specific dated quote.
How long does US customs clearance take?
CBP does not publish a standard clearance time, and no CBP statistic on average release times was found for this page. Release depends on whether the entry is complete and accurate, whether the Importer Security Filing was on time, and whether CBP selects the shipment for examination. An exam or hold can add days, which a licensed customs broker can track for a specific entry.
Does the Panama Canal still delay shipments from China?
Restrictions that slowed Panama Canal transits ended by mid-2024, according to UNCTAD's Review of Maritime Transport 2025. Whether any draft or transit limits applied in 2026 was not confirmed with the Panama Canal Authority for this page, so importers using Panama-routed services should check the carrier's current schedule.
