Sea Freight from China to USA: Routes, Ports & Transit Times
Quick Answer: How Sea Freight to the USA Works
Sea freight from China to USA involves shipping cargo via ocean vessels from major Chinese ports to US ports. The most common routes are to the US West Coast (Los Angeles, Long Beach, Seattle), which typically takes 12-18 days, and to the US East Coast (New York, Savannah, Houston), which typically takes 25-35 days. Your choice of destination port, container type, and service level determines overall transit time and cost.
Key Planning Points
- West Coast ports (LA/Long Beach) typically offer faster transit (around 12-18 days)
- East Coast ports (New York, Savannah) typically take longer (around 25-35 days) but serve the eastern market better
- FCL (Full Container Load) is faster and often more economical for larger shipments
- LCL (Less than Container Load) is suitable for smaller volumes
Major US Ports for China Imports
Understanding US port options helps you choose the best routing for your supply chain. Each port has different characteristics, throughput, and connectivity to inland destinations.
US West Coast Ports
Port of Los Angeles (LAX)
The busiest container port in the United States, Los Angeles handles millions of TEUs annually. It offers excellent connectivity to Southern California, the Southwest, and serves as a major gateway for cross-country distribution. The port has multiple terminal operators and extensive rail links.
Port of Long Beach (LGB)
Located adjacent to Los Angeles, Long Beach is the second-busiest US port. It is known for modern terminal facilities and efficient operations. Many carriers serve this port with frequent sailings from China. Combined with Los Angeles, the San Pedro Bay port complex forms the primary gateway for Asia-US trade.
Port of Seattle (SEA)
Seattle serves the Pacific Northwest market including Washington state, Oregon, and parts of Montana and Idaho. While smaller than LA/Long Beach, it offers less congestion and good connectivity to the Midwest via rail.
US East Coast Ports
Port of New York and New Jersey (NYC)
The largest port on the US East Coast, New York serves the nation's largest consumer market. It handles a diverse range of cargo and offers excellent connectivity to the Northeast corridor and inland destinations via rail and truck.
Port of Savannah (SAV)
Savannah is one of the fastest-growing US ports and the busiest in the Southeast. It offers efficient operations, less congestion than West Coast ports, and excellent connectivity to Southern and Central US markets.
Port of Houston (IAH)
Houston is the largest US port by tonnage and the busiest on the Gulf Coast. It serves Texas and the South-Central US, offering an alternative to West Coast entry for cargo destined for the southern half of the country.
China to USA Sea Freight Transit Times
Transit times vary significantly based on your chosen route and destination. These are estimated port-to-port transit times:
| US Destination Port | Transit Time (Days) | Best For |
|---|---|---|
| Los Angeles / Long Beach | 12-18 days | West Coast delivery, fastest transpacific route |
| Seattle | 14-20 days | Pacific Northwest, Midwest connections |
| New York | 25-35 days | Northeast market, direct Suez route |
| Savannah | 25-32 days | Southeast, Southern US distribution |
| Houston | 28-35 days | Texas, Gulf Coast, South-Central |
Note: These are port-to-port transit estimates. Door-to-door service adds additional time for pickup, customs clearance, and final delivery.
FCL vs. LCL: Which Container Type to Choose
Your cargo volume determines whether FCL (Full Container Load) or LCL (Less than Container Load) is more economical.
FCL (Full Container Load)
When you book an entire container for your cargo, you pay for the full container regardless of whether it is completely filled. FCL is typically:
- Faster transit (no consolidation/deconsolidation delays)
- Lower per-unit cost for larger volumes
- Less handling, reducing damage risk
- More predictable scheduling
Common FCL Container Types
| Container Type | Internal Dimensions (L×W×H) | Max Payload | Volume |
|---|---|---|---|
| 20' Standard | 5.89m × 2.35m × 2.39m | ~25,000 kg | ~33 CBM |
| 40' Standard | 12.03m × 2.35m × 2.39m | ~27,600 kg | ~67 CBM |
| 40' High Cube | 12.03m × 2.35m × 2.69m | ~26,680 kg | ~76 CBM |
LCL (Less than Container Load)
LCL is suitable when your cargo does not fill a complete container. Your goods are consolidated with other shippers' cargo in a shared container. LCL is typically:
- More economical for smaller volumes
- Requires consolidation at origin and deconsolidation at destination
- Involves more handling, slightly higher risk
- Longer total transit time than FCL
Rule of thumb: When your cargo exceeds approximately 15-20 CBM, FCL often becomes more cost-effective than LCL. Request quotes for both options to compare based on current rates.
Direct vs. Transshipment Services
Understanding the difference between direct and transshipment services helps you make informed decisions about transit time and cost.
Direct Services
Direct services sail from the origin port to the destination port without stopping at intermediate ports. Benefits include:
- Faster transit times
- Less handling, reducing damage risk
- More predictable schedules
- Usually slightly higher freight rates
Transshipment Services
Transshipment involves transferring cargo at an intermediate port (commonly in Hong Kong, Busan, or Singapore). This is common for:
- Ports with less frequent direct services
- Lower volume trade lanes
- More competitive freight rates
Transshipment adds approximately 3-7 days to transit time and involves additional handling, which may increase the risk of delays or damage.
Sea Freight Route Options
Your choice of route affects both transit time and cost. Here are the main options:
Transpacific West Coast Route
The most common route from China to the US West Coast. Vessels sail directly across the Pacific Ocean to Los Angeles, Long Beach, or Seattle. This offers the fastest ocean transit to the USA.
Suez Canal Route to East Coast
Sailing from China through the Suez Canal to US East Coast ports. This route serves New York, Savannah, and other Atlantic ports. While longer in distance, it avoids the Panama Canal's restrictions on very large vessels.
Panama Canal Route
An alternative East Coast route through the Panama Canal. Typically used for smaller vessels and can be competitive for certain cargo types and timing.
Port-to-Port vs. Door-to-Door
Understanding the difference between these service levels helps you choose the right option:
| Service Type | What's Included | Best For |
|---|---|---|
| Port-to-Port | Container movement between origin port and destination port only | Experienced importers with own customs broker and inland logistics |
| Door-to-Door | Pickup in China, ocean freight, customs clearance, delivery to US address | First-time importers or those wanting simplified logistics |
What Can Affect Sea Freight Transit
Several factors can impact your shipment timing:
- Port congestion: Peak season (August-November) often brings congestion at major US ports, adding days to delivery
- Weather disruptions: Typhoons in the Pacific, storms affecting vessel schedules
- Carrier schedule changes: Blank sailings (canceled voyages) during low-demand periods
- Customs clearance: Documentation issues or examinations can extend overall time
- Transshipment delays: Each transfer adds handling time and potential delays
How to Choose the Right Sea Freight Service
Consider Your Delivery Deadline
If you need fastest delivery, choose West Coast ports (LA/Long Beach). If your market is on the East Coast, factor in longer ocean transit plus cross-country rail/truck time.
Evaluate Total Cost
Compare total landed cost, not just ocean freight. East Coast ports may have higher ocean freight but lower destination handling and inland delivery costs for East Coast destinations.
Assess Your Volume
Larger shipments benefit from FCL. Smaller shipments may be more economical as LCL. Consider your cargo volume and frequency when deciding.
Plan for Peak Season
During peak season (typically August through November), book further in advance as space is limited and rates are higher.

Frequently Asked Questions
Port-to-port transit to US West Coast (Los Angeles/Long Beach) is typically 12-18 days. To US East Coast (New York/Savannah), it's typically 25-35 days. These are estimated transit times; door-to-door service adds additional time for pickup, customs clearance, and final delivery.
Choose based on your destination market. West Coast ports (LA/Long Beach) offer faster transit and are best for West Coast or cross-country distribution. East Coast ports (New York, Savannah) serve the eastern market better and may have lower total landed cost for East Coast destinations.
FCL (Full Container Load) means you book an entire container for your cargo. It offers faster transit, lower per-unit cost for larger volumes, and less handling. LCL (Less than Container Load) means your cargo shares a container with other shippers. It is more economical for smaller volumes but involves more handling and longer transit.
The most economical route depends on your specific situation. West Coast ports typically have more carrier options and competition, which can mean lower rates. However, the total landed cost to your specific destination may be lower via East Coast ports if your market is in the eastern United States.
Peak season for China-US sea freight typically runs from August through November, coinciding with retail inventory building for holiday seasons. During this period, rates are higher and space is more limited. Booking in advance is recommended.
Required documents typically include: commercial invoice, packing list, bill of lading, export customs declaration, and product-specific certifications depending on your cargo. For US import, you will also need ISF (Importer Security Filing) submitted prior to loading in China, and customs entry documentation.
Strategies to reduce costs include: consolidating shipments to achieve FCL volume, booking during off-peak periods, optimizing packaging to reduce dimensional weight, choosing the right port routing for your destination, and comparing total landed cost rather than just ocean freight.
