Ocean Freight Is How Most Ecommerce Products Enter the US

If you import products from China, Vietnam, India, or anywhere overseas, ocean freight is probably your primary shipping method. About 90% of global trade moves by sea. For ecommerce sellers importing containers of inventory, it is the most cost-effective way to move large quantities of goods.

Ocean freight rates fluctuate constantly. In early 2025, a 40-foot container from Shenzhen to Los Angeles runs roughly $3,500 to $5,500 depending on the carrier and booking window. That same route peaked above $15,000 during the 2021 supply chain crisis. Timing your bookings and understanding rate cycles can save you thousands per shipment.

How Ocean Freight Works: The Process from Factory to Warehouse

The basic flow looks like this:

• Your manufacturer delivers goods to the origin port (or a consolidation warehouse near it)
• A freight forwarder books container space on a vessel
• The container ships to the destination port (typically 14 to 30 days depending on the route)
• Customs clearance happens at the destination port
• A drayage truck picks up the container and delivers it to your warehouse or 3PL

Each step has its own timeline, costs, and potential delays. The ocean transit itself is usually the most predictable part. Port congestion, customs holds, and chassis shortages cause more problems than the actual sailing.

FCL vs. LCL: Full Container vs. Shared Freight

Full Container Load (FCL) means you book an entire container for your goods. Less than Container Load (LCL) means your shipment shares space with other importers. FCL is cheaper per unit if you can fill a 20-foot or 40-foot container. LCL makes sense when you are shipping under 10 CBM (cubic meters) of cargo.

A 20-foot container holds approximately 28 CBM. A 40-foot standard holds about 58 CBM. The 40-foot high cube (the most common for ecommerce) fits around 68 CBM. If your shipment fills more than half a 20-foot container, FCL almost always wins on price.

Ocean Freight Costs Beyond the Base Rate

The container rate is just one piece of the total cost. Here is what most sellers forget to budget for:

• Origin charges: $150 to $400 (terminal handling, documentation, container loading)
• Destination charges: $300 to $800 (terminal handling, port fees, chassis usage)
• Customs broker fees: $150 to $250 per entry
• Drayage (port to warehouse): $400 to $1,200 depending on distance
• Import duties: varies by HTS code (typically 0% to 25% of goods value)
• ISF filing: $25 to $75 per shipment

For a 40-foot container with a $4,000 base ocean rate, total landed cost often reaches $6,000 to $8,000 before duties. Duties can double that number for certain product categories.

Transit Times You Can Actually Plan Around

Here are realistic transit times from major origin ports to US destinations, including customs and drayage:

China (Shenzhen/Shanghai) to Los Angeles: 18 to 25 days total. China to New York (via Panama Canal or Suez): 30 to 40 days. Vietnam to Los Angeles: 20 to 28 days. India to Houston: 35 to 45 days.

Add 3 to 5 business days for customs clearance if everything goes smoothly. Add 1 to 2 days for drayage to a local warehouse. If customs flags your shipment for inspection, that can add 5 to 14 days.

Planning your inventory around these windows is critical. Most experienced sellers place orders 8 to 12 weeks before they need inventory in stock, depending on the route.

Common Problems and How to Avoid Them

Port congestion remains a recurring issue at major US ports. Long Beach and Los Angeles handle about 40% of US container imports. When volume spikes, wait times for unloading can stretch from 1 day to 2 weeks.

Blank sailings are another risk. Carriers cancel scheduled voyages when demand drops, which pushes your cargo to the next available ship. This is more common during the January to March slow season.

Documentation errors cause preventable delays. Make sure your commercial invoice, packing list, bill of lading, and ISF filing all match. One wrong HTS code can trigger a customs hold that costs you a week.

Working with a freight forwarder or ocean freight provider who handles both the booking and the customs side reduces these risks significantly. They track your shipment, manage documentation, and coordinate drayage so you are not chasing updates across three different companies.

When Ocean Freight Does Not Make Sense

Ocean freight is not always the right choice. If you need goods in 5 days, air freight is your only option (at 4 to 8 times the cost per kg). If you are shipping fewer than 2 CBM, the minimum charges for LCL eat into your margins. Small, high-value, time-sensitive products often justify air freight. Large, heavy, lower-margin goods belong on a ship.

The best approach for many sellers is a split strategy: send the bulk of your inventory by ocean and air freight a smaller quantity to cover you while the ship is in transit.
