DOT-compliant hazardous materials transport with certified hazmat carriers across all classes. Full 49 CFR compliance, proper placarding, hazmat manifests, CHEMTREC emergency response registration, and nationwide coverage on every regulated load.
Moving hazardous materials is not the place to cut corners. The regulatory requirements under 49 CFR are precise, the penalties for non-compliance are severe, and a single documentation error can result in fines, shipment delays, carrier liability, and reputational damage. MyExpressFreight works exclusively with FMCSA-certified hazmat carriers whose drivers hold active CDL hazmat endorsements and whose equipment meets all applicable DOT requirements for each hazmat class.
From common industrial chemicals and flammable liquids to compressed gases, corrosives, oxidizers, and Class 9 miscellaneous dangerous goods — our hazmat team verifies compliance at every step so your regulated freight moves safely, legally, and on time.
We handle the full range of regulated hazardous materials across DOT hazmat classes. Each class has specific packaging, labeling, placarding, and carrier certification requirements.
Hazmat freight touches nearly every sector of the economy. Our certified hazmat network serves shippers across all regulated industries.
Bulk and packaged industrial chemicals including solvents, acids, bases, and process chemicals. Class 3, 6, and 8 freight shipped with proper UN-spec packaging, hazmat labels, and DOT-compliant shipping papers on every load.
Flammable and combustible liquid coatings, industrial paints, architectural finishes, and solvent-based adhesives classified as Class 3. One of the most common hazmat commodities in US truckload freight — moved daily across our network.
Herbicides, insecticides, fungicides, and agricultural chemicals classified as Class 6 toxic substances. Seasonal demand during planting and application windows — proper packaging, labeling, and carrier certification required on every shipment.
Ammonium nitrate-based fertilizers, potassium nitrate, and industrial oxidizing agents classified as Class 5. Subject to additional security requirements under 49 CFR for theft-sensitive hazmat — routing restrictions and carrier background checks apply.
Propane, argon, helium, CO2, nitrogen, and industrial gas cylinders classified as Class 2. Cylinder packaging, proper valve protection, and gas-specific placarding required. Medical and industrial gas freight handled with appropriate carrier certifications.
Lithium-ion and lithium metal batteries (Class 9) for consumer electronics, EVs, and industrial applications. One of the fastest-growing hazmat categories — subject to IATA, IMDG, and 49 CFR packaging and quantity restrictions depending on mode.
Sulfuric acid, hydrochloric acid, nitric acid, caustic soda (sodium hydroxide), potassium hydroxide, and other industrial corrosives classified as Class 8. Requires UN-rated packaging, acid-resistant placards, and trained hazmat drivers on every load.
Chlorine compounds, sodium hypochlorite, calcium hypochlorite, and sanitizing agents classified as oxidizers (Class 5) or corrosives (Class 8). Strict segregation from incompatible materials, proper packaging, and hazmat-endorsed carriers required.
Every hazmat shipment requires specific documentation and compliance steps. MyExpressFreight helps ensure your freight moves with the right paperwork and procedures from origin to destination.
Answers to the most common questions about hazardous materials freight — DOT classes, shipper responsibilities, placarding, driver requirements, and costs.
Hazmat freight is any cargo classified as a hazardous material under DOT regulations (49 CFR) — substances that pose a risk to health, safety, property, or the environment in transport. This includes flammable liquids, compressed gases, corrosives, toxics, oxidizers, and miscellaneous dangerous goods. Shipping hazmat requires certified carriers with CDL hazmat-endorsed drivers, proper packaging and labeling, placarded vehicles, and compliant shipping papers with emergency response information on every load.
DOT classifies hazardous materials into 9 classes: Class 1 (Explosives), Class 2 (Gases), Class 3 (Flammable Liquids), Class 4 (Flammable Solids), Class 5 (Oxidizers and Organic Peroxides), Class 6 (Toxic and Infectious Substances), Class 7 (Radioactive Materials), Class 8 (Corrosive Substances), and Class 9 (Miscellaneous Dangerous Goods). MyExpressFreight handles Classes 2–9, with Class 1 (explosives) evaluated on a case-by-case basis. Each class has specific packaging, labeling, placarding, and documentation requirements.
Under 49 CFR, shippers must correctly classify the hazmat, use proper UN-specification packaging, apply required labels and markings, prepare accurate shipping papers with UN number, proper shipping name, hazard class, packing group, and quantity, provide emergency response contact information, and certify compliance with all applicable regulations. Shipper errors in classification or documentation can result in substantial fines (up to $84,467 per violation per day) and carrier liability. MyExpressFreight can help review your shipping papers for compliance before dispatch.
Placarding requirements depend on the hazmat class and quantity. Generally, placards are required for aggregate shipments of 1,001 lbs or more of most hazmat classes, and in any quantity for high-hazard materials like poison inhalation hazard (PIH) materials. Placards are diamond-shaped, at least 10.75 inches per side, and must be displayed on all four sides of the vehicle. The carrier is responsible for correct placarding, but the shipper must provide accurate hazmat class and quantity information to enable the carrier to placard correctly.
Hazmat freight rates run 15–40% above standard dry van on the same lane, depending on hazmat class, packing group, and commodity. The premium reflects CDL hazmat endorsement requirements, higher carrier insurance costs, documentation burden, and the smaller pool of certified hazmat carriers per lane. Contact MyExpressFreight for a hazmat quote — we return rates same-day on most standard Classes 3, 6, 8, and 9 lanes. More complex hazmat (gases, oxidizers, high-packing-group materials) may require 24 hours for full quote.
Yes — drivers transporting hazmat in quantities requiring placarding must hold a CDL with a Hazardous Materials (H) endorsement. Getting the endorsement requires passing a written knowledge test and undergoing a TSA security threat assessment (fingerprinting and federal background check). Drivers must also complete hazmat-specific training in recognition, classification, handling, documentation, and emergency response. All hazmat drivers in the MyExpressFreight carrier network are verified for active CDL-H endorsement before any hazmat assignment.
CHEMTREC (Chemical Transportation Emergency Center) is a 24-hour emergency response service that provides immediate technical assistance to first responders at hazmat incidents. Under 49 CFR 172.604, shippers must include an emergency response telephone number on hazmat shipping papers — this is typically the CHEMTREC number (1-800-424-9300) or a company 24-hour emergency contact. If a hazmat truck is involved in an accident or spill, first responders call this number to receive commodity-specific guidance for safe emergency response. Failure to include a valid emergency response number is a direct DOT violation.
"We ship Class 3 flammable liquids and Class 8 corrosives weekly. MyExpressFreight's hazmat carriers show up with proper placards, correct shipping papers, and CDL-H drivers every time. That level of compliance has never been guaranteed with other brokers."
"Our paint and coatings distribution runs 30+ hazmat loads a month. MyExpressFreight's documentation review caught a labeling error that would have been a DOT violation before the truck ever left our dock. That kind of oversight is invaluable."
"Getting certified hazmat carriers on short notice for pesticide season is brutal. MyExpressFreight has Class 6 capacity when our regular brokers come up empty — and their carriers arrive properly endorsed and equipped every time."
"Moving lithium battery freight requires carriers who actually understand the Class 9 requirements — UN38.3 testing, quantity limits, packaging specs. MyExpressFreight's team knows the regulations and sources carriers that do too."
"We had a hazmat incident during transit — a minor spill. MyExpressFreight coordinated with the carrier, CHEMTREC, and the local HAZMAT team within minutes. Their emergency response coordination turned a potential disaster into a managed incident."
"We've been shipping Class 5 oxidizers for 15 years. MyExpressFreight is the first broker that thoroughly understands the security plan requirements for theft-sensitive materials. The compliance piece alone makes them worth every cent."
