The largest US ports, and which are best for SMB importers

Ask which US port is the largest and you get a different answer depending on how you count. Measured by container volume, Los Angeles leads. Measured by total tonnage, Houston wins. Neither ranking tells a small-business importer what they came to find out: which port will get their goods to customers fastest and for the least money.

This guide gives you both rankings, so you can see how the major gateways stack up. Then it moves past the leaderboard into the part that touches your margin, meaning dwell times, drayage costs, how close a port sits to your buyers, and whether you can move a half-container without paying for a full one. By the end you will know not just which ports are biggest, but which one fits the way you import.

The largest and busiest ports in the US (ranked)

Two rankings dominate the conversation, and they answer different questions. Container volume tells you where manufactured goods and consumer products arrive. Total tonnage tells you where the heaviest cargo crosses the docks, most of which never goes near a store shelf. Here is where the major ports land on each.

Ranked by container volume (TEU)

Container traffic gets measured in twenty-foot equivalent units, or TEU. One standard 20-foot box counts as one TEU; a 40-foot box counts as two. It is the cleanest way to compare ports that move finished goods, which is most of what an importer cares about. These are the five busiest US container ports by 2024 volume:

Los Angeles and Long Beach sit next to each other and together move close to 20 million TEUs a year, roughly 40% of everything that reaches the US in a container. Treat any ranking as a snapshot. Volumes shift year to year, and 2024 brought double-digit growth at most of these gateways after a slow 2023.

Ranked by total tonnage

Rank the same ports by weight and the board reshuffles completely. Tonnage counts everything crossing the docks, including crude oil, grain, and chemicals that never sees a container. That is why Gulf Coast energy ports own this list even though few importers of finished goods will ever route through them.

For a business bringing in furniture, electronics, or apparel, the container ranking is the one that matters. The tonnage list mostly tells you where America’s oil and soybeans move.

Major US port profiles

Los Angeles & Long Beach (San Pedro Bay)

The two ports share San Pedro Bay and function as one enormous complex, the primary US gateway for trans-Pacific trade with Asia and China in particular. They offer deep water, huge terminal capacity, and rail connections east through the Alameda Corridor that no other pairing matches. The trade-off is congestion. Because this is the busiest gateway in the country, drayage and warehousing in the LA basin run expensive, and dwell times climb in peak season. If your goods come from China and your customers span the country or sit out west, this is the default choice.

New York and New Jersey

This is the busiest port on the East Coast, moving 8.70 million TEUs in 2024, and it serves the densest consumer market in the country. Rail and highway links into the northeast are strong, which makes it the natural landing point for goods bound for eastern seaboard buyers and for Asian cargo routed on all-water East Coast services. Expect higher real estate and trucking costs around the port, a reflection of the metro it sits in.

Savannah

Savannah is the fastest-growing of the big gateways, handling 5.55 million TEUs in 2024 after double-digit growth, and its Garden City Terminal is the single largest container terminal in North America. It runs less congested than the Los Angeles or New York complexes, offers strong rail into the southeast and midwest, and has a reputation among smaller importers for being easier to deal with. Georgia Ports keeps pouring money into capacity. For anyone selling into the southeast or looking to sidestep West Coast congestion, Savannah is often the smart middle option.

Houston

Houston tops the tonnage table and set a container record in 2024 at 4.14 million TEUs, with volume climbing fast as importers spread cargo away from the coasts. It anchors the Gulf, leans heavily on energy trade, and connects well into Texas and the south-central US. The Project 11 channel deepening will let bigger ships call. If your demand sits in Texas or the Gulf region, routing through Houston saves you the inland freight you would pay landing on either coast.

Other key ports (Norfolk, Seattle-Tacoma, Charleston)

Three more gateways earn a place on any shortlist. Norfolk, the Port of Virginia, is deep and uncongested, with excellent rail into the mid-Atlantic and the Ohio Valley. Seattle and Tacoma, operating together as the Northwest Seaport Alliance, offer the shortest sailing from north Asia and strong rail into the upper midwest. Charleston has deepened its harbour and competes head to head with Savannah as a southeast gateway. Each of these can beat the megaports on dwell time and drayage for the right destination, which is exactly the point of the next section.

How SMB importers should choose a port

The biggest port is rarely the right port for a small importer. Volume rankings measure scale, not what a shipment costs you or how reliably it lands. Four factors decide that, and none of them appear on a busiest-ports list.

Proximity to your customers and warehousing

The largest lever on your total cost is often the last leg, not the ocean crossing. A container that arrives in Los Angeles but serves buyers in Atlanta pays for two thousand miles of inland transport before it earns a cent. Match the port to where your goods end up. If you warehouse in the southeast, Savannah or Charleston beats Los Angeles even though Los Angeles is larger. Map your demand first, then pick the coast.

Congestion, dwell time, and reliability

Dwell time is how long your container sits at the port before it moves inland. At the busiest gateways during peak season that wait stretches, and every extra day risks demurrage charges. A less crowded port such as Norfolk or Savannah can get your box moving sooner than Los Angeles even with a longer ocean transit. When you are planning inventory, reliability beats raw speed.

Drayage and inland transport costs

Drayage is the short truck move from the terminal to a nearby warehouse or rail ramp. Rates run higher in congested, high-cost metros like Los Angeles and New York than they do in Savannah or Houston. Spread that per-container difference across a year of shipments and it reshapes your landed cost. Ask your forwarder for drayage quotes at two or three candidate ports before you commit to a lane.

LCL / consolidation availability

If you are not filling a whole container, you need less-than-container-load service, where your goods share a box with other shippers’ cargo. The major gateways carry the most LCL consolidation options and the most frequent departures, which means shorter waits and better rates. Smaller ports may have thinner coverage. For a business importing a few pallets at a time, consolidation availability can outweigh where the port sits on the leaderboard.

West Coast vs East Coast for imports from China

Most importers sourcing from China face the same fork: route through the West Coast or send goods the long way to the East Coast. Each choice trades speed against reach.

The West Coast wins on transit time. A container from Shenzhen or Ningbo reaches Los Angeles or Long Beach in roughly two weeks, the fastest ocean route from China to the US, and rail carries it east from there. That works well if you need goods quickly or your customers span the map.

The East Coast route runs longer, usually three to four weeks by way of the Panama Canal, but it drops cargo closer to northeastern and southeastern buyers with no cross-country rail leg. For a Florida or Carolinas business, an all-water service into Savannah or Charleston can land goods at a lower total cost than the faster West Coast option, because you save the inland freight that eats the time savings.

Risk plays into it too. Splitting volume across both coasts protects you when one gateway hits congestion, a labour dispute, or a weather event. Ship4wd books lanes into both, so you can match the route to the shipment rather than forcing everything through one door.

What are the 5 largest ports in the US?

By container volume in 2024, the five largest US ports were Los Angeles (10.3 million TEUs), Long Beach (9.65 million), New York and New Jersey (8.70 million), Savannah (5.55 million), and Houston (4.14 million). Ranked by total cargo tonnage instead, the top five look different: Houston, South Louisiana, Corpus Christi, New York and New Jersey, and New Orleans, because bulk energy and grain outweigh containers by sheer mass.

Which is the largest port in the United States?

It depends on the measure. The Port of Los Angeles is the largest by container volume and has held that spot for more than two decades, handling around 10.3 million TEUs in 2024. The Port of Houston is the largest by total tonnage, moving well over 250 million tons a year, most of it petroleum, chemicals, and bulk cargo. For an importer of containerised goods, treat Los Angeles as number one.

Choosing the right port lane with Ship4wd

The largest port and the right port are seldom the same. Los Angeles and Houston top the rankings, but your best gateway depends on where your customers are, how much congestion you can absorb, what drayage costs at each option, and whether you need LCL space. A smaller importer selling into the southeast often does better through Savannah than through the biggest West Coast complex, for the simple reason that the goods end up closer to the buyer for less.

Ship4wd books both West Coast and East Coast lanes from China and other origins, with LCL and full-container options and landed costs you can see before you commit. Tell us where your goods start and where your customers are, and we will help you match the shipment to the port that serves your margin.
