Port of Houston is first in the United States by tonnage, and five of the nine carrier tariffs name it outright
⚑ The short answer- Port of Houston moved 220.1M short tons in 2024 and ranks first in the United States by foreign waterborne tonnage. That figure counts liquid and bulk cargo alongside containers, so it answers how much moves through the port and not how many boxes, which is the question most of these results are actually asking.
- Port of Houston is named outright by COSCO, HMM, Hapag-Lloyd and Yang Ming across eight rate lines, and its median is $270. Until 01/08/2026 this profile said no line named it, and three of the remaining carriers still price it inside their ports-not-named-separately group, which means the rate you pay here was written without this port in mind, and no per-port median for Houston exists in our reading.
- Houston charges a Sustained Import Dwell Fee of $45 per unit per day from day 8 after free time expires. That is a port authority charge tied directly to how long the box sits, and it is the only such fee we have read at any US port — so two parties can bill you for the same days here.
- Gulf Coast results for Texas mix two different kinds of port. The question about the busiest port of entry in Texas is answered in these results by Laredo, a land crossing on the Mexican border rather than a seaport, and the related searches carry Corpus Christi and Texas City alongside Houston.

Is Houston the biggest port in the United States?
Port of Houston is first in the United States, and the measure has to travel with the claim: 220.1 million short tons of foreign waterborne tonnage in 2024, a figure that counts liquid and bulk cargo alongside containers. On containers it is not first — Port of Los Angeles moved 10,239,318 TEU in calendar 2025. Both statements are true and neither survives without its measure.
Three separations belong here because the results mix them in. The busiest Texas port of entry in those results is Laredo, which is a land crossing on the Mexican border rather than a seaport. Texas is not one port: Corpus Christi and Texas City are separate places with separate figures. And tonnage is not boxes. How Houston compares with its actual neighbours: how houston and new orleans actually differ, how gulf coast and east coast actually differ, the Gulf Coast ports compared.

Free time at Houston is published by five carriers under the port's own name
Port of Houston runs on a clock nobody wrote for it. Eight of the nine carriers publish a number of free days — four days with most of them, five with COSCO — and not one of those lines names Houston. The days apply here through a residual group, so the count that governs your box was set without this port in mind.
Port of Houston’s own tariff would settle both the days and the hour, and we have not located it at all. That is weaker than the cell on the New York or Los Angeles profiles, where the authority’s document at least ranks in the port’s own results. The practical consequence is simple: a tariff that does not name your port still runs a clock on it.
How this profile is built · what we are paid
- Every figure below carries the document it was read from and the date it was read. A figure we have not read does not become a number: the cell says whether the document is unpublished, located but unopened, or simply not checked yet.
- The port’s own tariff outranks anyone’s summary of it, including ours — where the rule or tariff number is known it is printed so you can cite it.
- No port, terminal or carrier has paid to appear on this page or to be described in any particular way, and no link on this site is a referral link.

What a box picks up at Houston
Port of Houston fills this stack in the opposite order from every other profile on the site. The carrier line carries eight rate lines here with a median of $270, five carriers naming the port outright. The local-fees line, empty almost everywhere else, is the one we have read here too: $45 per unit per day from day 8 after free time expires — so two parties bill the same day.
An empty carrier cell here does not mean we failed to open something. Nine tariffs were read in full and four of them name Houston outright, which is what changed on 01/08/2026: the empty cells left here belong to charges nobody publishes, not to a port nobody names.

What an empty-looking cell means: not published — the source publishes no figure here not checked yet — we have not read the document yet
Two parties can bill for the same days here, and they start on different days. The carrier’s demurrage starts when its free time ends, under a tariff that does not name Houston. The port’s own dwell fee starts on day 8 after free time expires, under a schedule that does. Only the first of the two appears in your carrier tariff, and it appears there without this port’s name on it.

Houston terminals, starting with Bayport
Port of Houston runs its container business at Bayport and Barbours Cut, and neither is named in any of the nine tariffs we read. That makes this table the opposite of the New York one: here the terminals are places, not carriers of rates, and which berth your service calls at does not change the demurrage line.
The two container terminals, with the fields a driver needs. Bayport is a search query in its own right and returns a local pack, which is exactly the format we cannot yet fill.| Terminal | Named in any tariff? | Address | Gate hours and appointments | Storage tariff |

Dwell at Houston, where the number is unread and the charge for it is not
Port of Houston is the one port on this site where we know what dwell costs and not how long it lasts. Not a single dwell figure for Houston has been read, while dwell time is one of the questions this port is asked most — and the charge for dwell is read in full, at $45 per unit per day from day eight.
That inversion reads like an editing error and it is the most informative line on the page: the price of the quantity is known and the quantity is not. It is the exact mirror of Los Angeles, which has five dwell figures in circulation and no port fee for dwell at all.
Which dwell each port means, and who publishes a definition: how long a box sits, and which dwell is meant. Which ports are backed up right now: which ports are backed up right now.
The Sustained Import Dwell Fee, and why it is the only local fee we have read
Port of Houston publishes the only port authority charge tied directly to dwell that we have read anywhere on this site. It matters beyond Houston: it is the read proof that a port can bill for time directly, rather than only through the carrier’s tariff.

Two and a half ports of roughly thirty. This is the whole of what we have read on local fees across the site: Houston in full, Los Angeles in full, and one unconfirmed sighting at Long Beach. Every other port’s row says not checked yet, and that is gap J.
What Port Houston publishes
Port Houston publishes its charge more readably than its statistics, which is the mirror image of Los Angeles. Both disclose about half of what an importer needs, and they disclose different halves — a thing you can only see by asking every port the same eight questions.

Every port we cover, with the same eight questions asked of each: every US container port we cover.
Getting the box out of Houston
Port of Houston serves Texas by road and the interior by rail, and even the leg from the terminal into the city is asked about as its own question. The road leg is the line this site cannot price at any port.

What goes wrong at Houston, and who pays
The vessel skips Houston
Your box is discharged at another Gulf port and comes back by road, and the tariff that applies is the one where it landed.
Who pays depends on the cause: the carrier for its own schedule change, the shipper for a late gate-in.
The box is held
A customs or agency hold does not stop the clock, and here it can start a second one: free time keeps running, and the port’s dwell fee begins on day eight.
Cargo interest, to two different billers.
An examination is ordered
The container moves to an examination site and back, and those days count against both clocks.
Cargo interest pays the move and the time.
The box passes day eight
This is the local one. At day eight after free time expires the port’s own Sustained Import Dwell Fee switches on at $45 per unit per day, on top of whatever the carrier is already charging.
Cargo interest, and the second invoice comes from the port authority rather than the carrier.
What we have not read on this block. The hold types, who lifts each one, at whose cost and within what deadline are gap Q, and the carriers’ own rollover terms are gap R. This block describes the shape of each failure and who the bill lands on; it does not publish deadlines we have not read.
Both of the first two have their own page: when the ship skips your port and what to do when the box will not move.
Your rights under US federal ruleIf a Houston demurrage invoice arrives
Port of Houston demurrage arrives on a carrier’s invoice, not the port’s, and that invoice answers to a federal rule: 46 CFR Part 541, in force since 05/28/2024. The rule has been before the D.C. Circuit twice since, and the decision of 09/29/2025 changed who may be billed — so the text to read is the current one at eCFR, not a summary of the 2024 announcement.
One local caveat matters here more than anywhere else on the site. That federal rule governs carrier demurrage and detention. Port Houston’s own dwell fee is a different charge from a different biller, and whether the same rule reaches it is something we have not checked.
What the invoice has to contain, and how the dispute runs: the federal rules your invoice has to meet.
Descriptive, not legal advice. The tariff and the invoice in your own file govern your case.
Licensed intermediaries around Houston
Port of Houston sits in a metro we have not counted in the Federal Maritime Commission’s register of ocean transportation intermediaries — the register was counted for Los Angeles with Long Beach and for Savannah, and not here. The two standing caveats apply whenever it is: the count is a metro figure rather than a port figure, and absence from the register is not a finding about a company.
What this register covers, and what it does not. It covers the ocean leg. It does not license drayage carriers and it does not license terminal operators, so the absence of a company from it is not a finding about that company. Half of the route you are buying is regulated by a different agency.

Questions about the Port of Houston and Texas imports
Is Houston the biggest US port, and by which measure?
On foreign waterborne tonnage yes, at 220.1M short tons for 2024. On containers no — Los Angeles moved 10,239,318 TEU in calendar 2025. Two different measures, both true, and the tonnage one includes liquid and bulk.
What is the busiest port of entry in Texas?
The results answering that question point to Laredo, which is a land crossing on the Mexican border rather than a seaport. A port of entry is a customs code, and Texas holds them on land as well as on water.
How much is demurrage at Houston?
No line naming Houston appears in any of the nine import tariffs we read. The rate comes from each carrier's group for ports not named separately, so it was written without this port specifically in view.
What is a dwell time fee?
At Houston it is literal: a Sustained Import Dwell Fee of $45 per unit per day from day 8 after free time expires, levied by the port. It is the only charge of its kind we have read at any US port.
Why am I being charged twice for the same days?
Because there are two billers here. The carrier bills demurrage under its tariff and the port bills its own dwell fee, and the two clocks start on different days and count from different events.
What is the dwell time at the Port of Houston?
No dwell figure for this port has been read here, so the cell says not checked yet. We have read what the port charges for dwell without having read how long boxes actually sit.
What are the major shipping ports in Texas?
Texas is not one port. Corpus Christi and Texas City sit alongside Houston in these results, and on the entry side Laredo appears as a land crossing rather than a seaport.
How many free days at Houston?
Whatever your tariff's group line says — four with most carriers and five with COSCO. None of those lines carries the name Houston, and the clock runs on it regardless.
