Hazmat Shipping in Mississippi
Mississippi's hazmat freight follows the Mississippi River refinery corridor, the Gulf Coast petrochemical strip near Pascagoula, and agricultural chemical distribution across the Delta farming region. The state serves as a north-south conduit between Gulf Coast chemical production and Midwest consumption.
Industries Using Hazmat in Mississippi
These industries drive Hazmat freight demand in Mississippi.
Petroleum Refining
Chevron's Pascagoula refinery (330,000 bpd) is the largest on the Gulf Coast east of Louisiana. It produces gasoline, diesel, and jet fuel distributed across the Southeast. Multiple smaller refineries and terminals line the Mississippi River.
Agricultural Chemicals
The Mississippi Delta — one of America's most productive farming regions — consumes large volumes of herbicides, insecticides, and fertilizers for cotton, soybeans, and rice. Greenville and Vicksburg are primary ag-chem distribution hubs.
Shipbuilding Chemicals
Huntington Ingalls Industries in Pascagoula builds Navy destroyers and Coast Guard cutters, consuming industrial paints, coatings, welding gases, and specialty chemicals classified as Class 2, Class 3, and Class 8.

Pascagoula-area hazmat operations are directly impacted by Gulf hurricanes. MEMA coordinates hazmat evacuation protocols with chemical facilities, and carriers may be directed to pre-position fuel loads at inland staging areas during hurricane watches.
Market Insights: Hazmat in Mississippi
Refinery Scale
Chevron Pascagoula at 330,000 bpd generates substantial hazmat freight. Combined with smaller Mississippi River terminals, the state produces enough fuel to support dedicated tanker fleets.
Delta Seasonality
Agricultural chemical demand in the Delta peaks sharply in spring (March-May). Carriers who serve the Delta during planting season can earn premium rates, but summer and winter volumes are considerably lower.
Hazmat Shipping in Mississippi — FAQs
What is Mississippi's largest hazmat shipper?
The Chevron Pascagoula refinery at 330,000 barrels per day is the state's dominant hazmat freight generator. Fuel products from this refinery distribute throughout the Southeast via tanker truck and pipeline.
How does hurricane season affect Mississippi hazmat?
Gulf hurricanes can shut down the Pascagoula refinery and coastal chemical facilities for days to weeks. Pre-storm fuel staging creates demand spikes. Post-storm recovery generates emergency hazmat needs for fuel delivery and chemical cleanup.
Is agricultural chemical hauling viable in Mississippi?
During spring planting season (March-May), ag-chem hauling in the Delta is very profitable. Outside of planting season, volumes drop significantly. Most carriers combine Delta ag-chem work with Gulf Coast petrochemical loads for year-round utilization.
