Imported goods do not stop at the port. They land, clear, and move inland along a small number of well-worn corridors to a small number of very large warehouse markets. Understanding that geography is what turns "we import from Asia" into a specific shortlist of submarkets.
This guide maps the gateways, the corridors that feed off them, and the warehouse markets that grew up along each.
The gateways
US container traffic is heavily concentrated. Year-to-date figures for 2025, compiled from port authority statistics through roughly October/November, put the five largest container ports as:
| Port | 2025 YTD volume |
|---|---|
| Los Angeles | 9.44 million TEU |
| Long Beach | 8.23 million TEU |
| New York & New Jersey | 7.50 million TEU |
| Savannah | 4.80 million TEU |
| Houston | 3.97 million TEU |
Two things follow from that table.
First, San Pedro Bay dominates. Los Angeles and Long Beach sit adjacent to each other and together handle far more than any other US gateway. When people say "the West Coast," operationally they usually mean these two.
Second, the gap to third place is smaller than it used to be. New York & New Jersey, Savannah, and Houston have all grown as importers diversified away from a single West Coast entry point — a trend accelerated by port congestion, labour disputes, and the expansion of the Panama Canal allowing larger vessels to reach the East and Gulf coasts directly.
Why the port choice is often not yours
Before optimising, check whether you control the decision. Your port of entry may be set by your supplier's origin port and the carrier's service string, by your Incoterms, or by your freight forwarder's contracts. Businesses buying on terms where the seller arranges shipping frequently discover they have less control than they assumed.
If you do control it, the trade-off is broadly: West Coast is faster from Asia but feeds a longer inland leg to eastern population centres; East and Gulf coasts take longer on the water but land closer to a large share of US consumers.
The corridors and the markets they created
Warehouse geography in the US is legible once you see it as gateways plus corridors.
Southern California — Inland Empire
Goods landing at Los Angeles and Long Beach move a short distance east into the Inland Empire (Riverside and San Bernardino counties). It is the largest concentration of warehouse space in the country, built specifically to absorb San Pedro Bay volume.
Use it when: you import heavily through the West Coast, you serve the large Southern California consumer market, or you need the shortest possible dwell between vessel discharge and rack.
Watch for: it is a mature, expensive market with real constraints — land scarcity, local opposition to new warehouse development, and labour competition. Cheap it is not.
Chicago — the national rail interchange
Chicago is the pivot of the US freight rail network, the point where the western and eastern railroads interchange. That, plus its central position and enormous local consumer base, makes greater Chicago one of the largest industrial markets in the country.
Use it when: you need national reach, you move volume by rail, or you serve the Midwest.
Watch for: rail interchange in Chicago is famously congested; transit time through the terminal can be a real variable. Winter weather is an operational factor that coastal planners underestimate.
Savannah and the Southeast
Savannah has grown quickly as an East Coast gateway, feeding warehouse development in coastal Georgia and inland toward Atlanta, which functions as the distribution hub for the Southeast.
Use it when: your demand is weighted to the Southeast and Eastern Seaboard, or you want an alternative to West Coast entry.
Watch for: Georgia is an inventory-tax state, though freeport exemptions are widely adopted at county level — see Inventory and Property Tax by State before assuming a cost.
Pennsylvania — the I-78/I-81 corridor
Central and Northeastern Pennsylvania grew into a major distribution corridor for a simple reason: a very large share of the US population lives within a day's truck drive. It serves the Northeast without paying Northeast metro rents, and it feeds off the Port of New York & New Jersey.
Use it when: next-day or two-day service to the Northeast megalopolis is the requirement.
Watch for: it is no longer a secret. Development has been heavy and the corridor's cost advantage over the metros has narrowed.
Texas — Houston and Dallas–Fort Worth
Houston is the Gulf gateway and an energy and industrial centre in its own right. Dallas–Fort Worth, several hundred kilometres inland, is one of the most active industrial development markets in the country, serving as a central-US distribution point with good highway and rail access and no state income tax.
Use it when: you want central-US coverage, you import through the Gulf, or you are also moving goods across the Mexican border.
Watch for: Texas taxes business inventory. Quantify it, and check the freeport exemption position in the specific county.
The secondary inland hubs
Beyond the majors, a set of inland markets exist because of drive-time geography rather than ports: Memphis (air freight, anchored by a very large express hub), Columbus and Indianapolis (one-day truck reach to a large share of the eastern US), Kansas City (central rail), and the Louisville area (air express).
These are frequently the right answer for a second node once you outgrow a single warehouse, and they are often cheaper than the primary markets.
Clearing customs inland
A point that changes the analysis and is often missed: goods do not have to clear customs at the port where they land. They can move in bond to an inland location and be entered there.
This decouples "where my container arrives" from "where my warehouse is." It is why inland hubs hundreds of kilometres from any coast can serve as primary import distribution points. If you are importing as a non-resident, note that the resident agent requirement attaches to the state of the port of entry or of the remote filing location — see Importer of Record.
How to actually choose
The corridors above are context, not an answer. The method is the one in How to Start Your Warehouse Search:
- Plot your demand by volume. Where do orders actually ship, weighted by units rather than order count?
- Overlay your inbound gateway, if you control it.
- Draw your service promise as a drive-time radius. One-day and two-day ground coverage from candidate markets is the single most useful map you can build.
- Model total cost, not rent — outbound freight usually dominates, and it moves in the opposite direction to rent.
- Then check the local factors: labour availability, inventory tax, freeport exemption, FTZ status, and utility capacity.
Most businesses find that two or three markets survive this and are close enough that the deciding factor becomes which one has the right building available on the right timeline.
A note on these figures
Port volumes and market sizes move every year, and published industrial market statistics vary between brokerages because they define market boundaries differently. Use the ordering and the geography, which are stable, rather than treating any single number as current. For live figures, go to the port authorities directly and to the quarterly market reports published by the major brokerages for each submarket.
