Keelway
Houston, TX · Port + petrochem + energy

AI carrier triage for the Gulf's most specialized freight market.

Houston runs three different freight worlds inside one metropolitan radius. The Port of Houston pushes container drayage with TWIC-card discipline and per-terminal appointment rhythms. The Ship Channel petrochemical complex moves tank-truck and ISO-tank specialty freight under hazmat regulations no other US market sees at this density. And the energy corridor headed west to the Permian runs the same oilfield specialty-equipment carrier base DFW does. Keelway recognizes the carrier-reply shape and ranks the right way per load type.

The Houston freight reality

A Houston brokerage's inbox is the most specialty-skewed in the country. On a single day a coordinator can be ranking drayage replies for a Barbours Cut terminal pickup, hazmat tank-truck carriers for a methanol move out of the Ship Channel, and step-deck flatbed for a Permian frac-equipment haul. Three completely different carrier bases, three different sets of ranking weights, three different sets of compliance signals to check on every reply.

The petrochemical specialization is what sets Houston apart from every other US freight market. The Bayport, Channelview, Baytown, La Porte, and Pasadena industrial corridors collectively form the largest petrochemical processing cluster on Earth. Tank-truck and ISO-tank carriers there operate under hazmat regulations (49 CFR §172, §177, §178), Coast Guard rules at port-adjacent facilities, TSA HMSP credentialing for hazmat-endorsed drivers, and shipper-specific certifications that aren't portable to dry-van freight.

What Keelway tunes for Houston brokers

Hazmat

Endorsement + placarding + tank-spec parsed

Hazmat carrier replies get scored on MC hazmat endorsement status, placarding compliance history, tank specification (DOT-407 / DOT-412 / MC-307 / MC-331), TSA HMSP credentialing where applicable, and route-restriction history. Mismatches surface before booking.
Port

Bayport / Barbours Cut / Turning Basin

Per-terminal access tracking on Port of Houston drayage moves. TWIC-card driver requirement surfaces as a verification step. Chassis disclosure (TRAC, DCLI, Flexi-Van) parsed the same way as LA / Long Beach. Demurrage timing built into ranking.
Tank-truck

ISO-tank, ISO-container, tank-spec matching

Tank-truck and ISO-tank carriers represent a specialty segment most freight-broker TMSs don't handle cleanly. Keelway parses tank specification, kosher certifications, prior-product residue specs, and cleaning-bay receipt requirements out of carrier replies where present.
Energy

Permian-bound oilfield freight handled

West-bound energy freight inherits the DFW oilfield calibration — specialized step-decks, RGNs, sand kingpin chassis, well-pad-access expertise. Carriers with demonstrable Permian freight history get ranked higher on Permian-bound lanes by default.

The TMS shape we see most in Houston

Houston's broker population is bimodal by specialization. General-freight mid-market and enterprise brokerages run Aljex (Descartes) and McLeod LoadMaster in proportions similar to the national average. Tank-truck, ISO-tank, and hazmat-specialty shops skew more toward BrokerWare, Mercury Gate / Infios (for multimodal), and in-house tooling than other markets — a function of how specialized the freight is. Keelway integrates natively with the mainstream stack. Specialty tank-truck brokerages should ask about the hazmat-specific roadmap.

The Houston playbook above is one slice of the broader Keelway product — our AI-native freight broker platform covers carrier-email triage, FMCSA-grade carrier vetting, rate extraction, and TMS write-back across every US freight market.

Frequently asked questions

Why a dedicated page for Houston freight brokers?+
Houston is unique among US freight markets in three dimensions at once. (1) Port of Houston — third-largest US container port by tonnage, with the Bayport, Barbours Cut, and Turning Basin terminals driving dense drayage volume. (2) The world's largest petrochemical complex along the Houston Ship Channel and Gulf Coast — tank-truck, ISO-tank, and hazmat-heavy specialty freight that doesn't exist at this density anywhere else. (3) The energy corridor heading west to the Permian, plus shale-play freight from the Eagle Ford. Each of those carrier-reply mixes is structurally different from the others; Keelway is built to recognize the shape.
How does Keelway handle hazmat-heavy lanes out of Houston?+
Hazmat carriers carry signals the standard dry-van ranker misses — hazmat endorsements on the MC, placarding compliance, route-restriction history, specific UN-class certifications, tank-spec match (DOT-407 / DOT-412 / MC-307 / MC-331), and Coast Guard / TSA / HMSP filings where applicable. Keelway parses these out of carrier replies and ranks against the load's hazmat requirements. See /verticals/hazmat-broker for the deeper read.
What about port drayage at the Port of Houston terminals?+
Bayport, Barbours Cut, and Turning Basin each run their own appointment systems and gate-hour rhythms. Same drayage discipline as LA / Long Beach — chassis disclosure parsed and ranked against the load's chassis requirement (TRAC, DCLI, Flexi-Van), per-terminal access tracking, demurrage timing built into ranking. The TWIC-card requirement for drivers entering port facilities surfaces as an additional verification step. See /verticals/intermodal-broker for the full drayage ranking spec.
Does Keelway integrate with the TMSs Houston brokerages typically run?+
Yes. Houston's broker population skews more diverse than most markets because of the hazmat / petrochemical specialization — Aljex (Descartes) and McLeod remain the mid-market and enterprise standards, but tank-truck and ISO-tank specialty brokerages run more BrokerWare, Mercury Gate/Infios (for multimodal), and in-house tooling than the national average. Keelway integrates with the mainstream broker TMSs natively. Pure tank-truck specialists should ask about the hazmat-specific module roadmap.
What about the energy corridor west of Houston?+
The freight headed west to the Permian basin overlaps with the Dallas-Fort Worth oilfield freight pattern — same specialized carrier base (step-decks, RGNs, sand kingpin chassis), same well-pad-access expertise. Keelway's default weights for Houston-origin energy-corridor loads pull from the DFW oilfield calibration. Brokerages running a heavy Permian book on Houston-origin loads should expect similar ranking behavior to a DFW-domiciled broker.
