Requirements
FMCSA insurance requirements for hazmat: $1M or $5M?
Hauling hazardous materials changes the insurance a motor carrier must carry and how it proves it. Below are the federal minimums by type of load, who they apply to, how proof of coverage is filed and what the hazmat safety permit adds.
Hazmat insurance minimums by load
The minimums sit in one table in 49 CFR 387.9 (current in the eCFR as of October 2026). Compared with the $750,000 most for-hire general freight carriers need, hazmat loads start at $1 million and reach $5 million for the most dangerous cargo.
Two definitions in 49 CFR 387.5 decide your tier. “In bulk” generally means a containment system holding more than 3,500 water gallons. For Division 1.1 to 1.3 explosives and Zone A poison-inhalation materials, any quantity counts as bulk.
“Hazardous substances” is also a defined term in 49 CFR 171.8, narrower than hazardous materials in general, so confirm your cargo’s entry with your shipper before you buy coverage.
| Cargo | Vehicle and trip | Minimum |
|---|---|---|
| Non-hazardous property (for comparison) | For-hire, interstate, 10,001 lb GVWR or more | $750,000 |
| Oil, hazardous waste and other listed hazmat not in the $5 million tier | 10,001 lb or more; interstate in any quantity, intrastate in bulk only | $1,000,000 |
| Hazardous substances in bulk in cargo tanks, portable tanks or hopper-type vehicles | 10,001 lb or more; interstate or intrastate | $5,000,000 |
| Bulk Division 2.1 or 2.2 gases, such as propane | 10,001 lb or more; interstate or intrastate | $5,000,000 |
| Division 1.1 to 1.3 explosives and Zone A poison-inhalation materials, any quantity | 10,001 lb or more, interstate or intrastate; under 10,001 lb, interstate | $5,000,000 |
| Highway route controlled quantity of Class 7 radioactive material | 10,001 lb or more, interstate or intrastate; under 10,001 lb, interstate | $5,000,000 |
Who the hazmat minimums apply to
Hazmat is where the federal insurance rules reach beyond for-hire interstate trucking. Under 49 CFR 387.3, they apply to any motor carrier hauling hazardous materials, substances or wastes in interstate, foreign or intrastate commerce, and the 387.9 table lists private carriers alongside for-hire ones.
The rule has limits worth knowing:
- Light vehicles: trucks under 10,001 pounds GVWR are exempt unless they carry any quantity of Division 1.1 to 1.3 explosives, Zone A poison-inhalation materials or a highway route controlled quantity of radioactive material in interstate commerce.
- Intrastate, non-bulk: the federal rule does not cover non-bulk oil or hazmat moved within one state, except highway route controlled quantities of radioactive material. Your state may set its own limits.
- Intrastate, bulk: bulk loads within one state need the federal $1 million or $5 million minimum.
- Private carriers of non-hazardous freight: they fall outside these federal minimums entirely.
How you prove hazmat coverage
Every carrier subject to these rules must keep proof at its principal place of business, under 49 CFR 387.7(d). For most carriers that proof is an MCS-90 endorsement on the auto liability policy; a Form MCS-82 surety bond or FMCSA approval to self-insure are the alternatives. The proof is public information and must be produced when a member of the public reasonably asks for it.
For-hire carriers with operating authority also need their insurer to file proof with FMCSA, under 49 CFR 387.301. Under 387.313, a BMC-91 certificate covers the full limit, and a BMC-91X covers the full limit or any level of aggregation. That matters at $5 million: a primary policy and excess layers from different insurers can be combined, with each insurer filing its own BMC-91X.
Under 49 CFR 387.5, public liability includes environmental restoration: the cost of removal and of limiting harm after cargo is released onto land or into air or water.
Loads that need a hazmat safety permit
Some loads also need a federal Hazardous Materials Safety Permit (HMSP), which applies to intrastate as well as interstate carriers. FMCSA’s program brochure lists the loads covered by 49 CFR 385.403:
- A highway route controlled quantity of Class 7 radioactive material
- More than 25 kg (55 pounds) of Division 1.1, 1.2 or 1.3 explosives, or a placarded amount of Division 1.5
- Zone A toxic-by-inhalation materials in packaging over 1 liter
- Zone B toxic-by-inhalation materials in bulk packaging over 450 liters (119 gallons) for liquids or 454 kg (1,000 pounds) water capacity for gases
- Zone C or D toxic-by-inhalation materials, which can include anhydrous ammonia, in bulk packaging of 3,500 gallons or more
- Methane, natural gas or another liquefied gas that is at least 85% methane, in bulk packaging of 3,500 gallons or more
Permit proof, renewals and lapses
To get an HMSP you send FMCSA an MCS-90 showing the 387.9 limit for your materials, plus your PHMSA hazmat registration. Under 49 CFR 385.407, FMCSA also requires a satisfactory safety rating and a security program.
Carriers without a rating can get a temporary permit valid for 180 days. Permits are renewed every two years with a current MCS-90, and FMCSA can suspend or revoke one if you fail to maintain the required insurance.
Under 49 CFR 387.7(b), required policies must stay in force continuously, and cancelling one takes 35 days’ written notice from the insurer or the carrier.
How to meet the requirement without overpaying
The federal minimum is a floor, and the right program depends on exactly what you haul.
Insurers differ in which hazmat classes they will write, so comparing quotes matters. A broker such as Florin can compare options from several insurers for the limits your loads require.
- Match every commodity to its 387.9 entry before you shop. Hauling only $1 million loads doesn’t require a $5 million program, but one bulk gas or explosives load without it is a violation.
- Price the $5 million tier as layers: a primary policy plus excess from other insurers, each filing its own BMC-91X.
- Keep your PHMSA registration and safety rating current, since the safety permit depends on both.
- Read shipper and broker contracts. If they require more than the federal minimum, the higher number is the one you carry.
- Give underwriters exact commodities, hazard classes and tank sizes so the quote matches your loads.
Frequently asked questions
Do private carriers need hazmat insurance?
Yes. The 49 CFR 387.9 table applies the $1 million and $5 million minimums to private carriers as well as for-hire ones. Private carriers do not file with FMCSA but must keep an MCS-90 or MCS-82 at their principal place of business.
Does a pickup hauling hazmat need $5 million in coverage?
Only for certain loads. Vehicles under 10,001 pounds GVWR need $5 million when they carry Division 1.1 to 1.3 explosives, Zone A poison-inhalation materials or a highway route controlled quantity of radioactive material interstate; otherwise the federal hazmat minimums do not apply to them.
Do intrastate hazmat haulers need the federal limits?
Bulk loads do: $1 million or $5 million depending on the material. Non-bulk intrastate loads fall outside the federal rule, except highway route controlled quantities of radioactive material, but your state may set its own requirements.
Does required hazmat coverage pay for spill cleanup?
The federal definition of public liability includes environmental restoration, so required coverage must respond to cleanup claims after a release, up to the minimum. Damage to your own truck needs separate physical damage coverage.
