Interstate or Intrastate: Does the Carrier Fit the Load?

What the definitions say

49 CFR 390.5T defines interstate commerce as trade, traffic or transportation in the United States between a place in a state and a place outside it, including outside the country; between two places in a state through another state or country; or between two places in a state as part of trade, traffic or transportation originating or terminating outside the state or the country. Intrastate commerce is everything else.

The third clause is the one that catches a broker. A short haul from a port, rail ramp or cross-dock to a warehouse in the same state can be interstate commerce when the freight is moving to or from another state or country. Whether a particular leg is part of a continuing interstate movement turns on the facts of the shipment, so ask the shipper where the freight came from and where it is ultimately going, and record the answer with the load.

Read the carrier operation field

SAFER’s field definitions describe Carrier Operation as identifying the carrier as engaged in interstate, intrastate hazardous-material or intrastate non-hazardous-material transport. The same help page notes that a State Carrier ID is often used in place of the USDOT number for intrastate carriers, and that a NOT AUTHORIZED operating status does not apply to private or intrastate operations. An intrastate-only carrier showing no operating authority is therefore normal for that carrier and a problem only for interstate freight.

VerifyCarrier’s DOT lookup reads the carrier-operation code from the FMCSA Company Census File and shows it as Interstate, Intrastate only (hazmat) or Intrastate only (non-hazmat). The field is carrier-reported on the registration form; the guide to the SAFER Company Snapshot explains how to read it beside the other identity fields, and the guide to carrier authority statuses explains the operating-status values.

A USDOT number does not settle it

FMCSA requires a USDOT number for commercial vehicles in interstate commerce and for intrastate carriers hauling hazardous materials that need a safety permit. It also lists states that require their intrastate commercial registrants to obtain a USDOT number, including Texas and California. A purely intrastate carrier can therefore hold a valid USDOT number.

Operating authority is a separate registration. In general, for-hire carriers transporting federally regulated commodities in interstate commerce need an MC number in addition to the USDOT number; private carriers and for-hire carriers hauling only exempt commodities do not. The guide to USDOT and MC numbers covers the difference between an identifier and a grant of authority.

State authority answers a different question

Some states issue their own carrier numbers and authority for work inside the state. Texas DMV explains that a USDOT number is an identifier, not operating authority: crossing state lines requires interstate authority from FMCSA, staying in Texas requires a TxDMV certificate, and a carrier doing both kinds of work needs both because one does not cover the other.

In California, the Highway Patrol issues the carrier identification number, or CA number, which the DMV uses as the Motor Carrier Permit number. A valid TxDMV certificate or California permit shows that a carrier may haul inside that state. It does not supply the federal authority an interstate movement needs.

Before tender

Check the insurance filing that matches the authority the load needs; the guide to verifying carrier insurance explains filing versus coverage. An illustrative note: “Origin in-state warehouse; shipper confirms freight arrived by rail from out of state. Treated as interstate. Carrier record reads Intrastate only (non-hazmat), no active MC authority. Not tendered; replacement reviewed.”

A recommended sequence, to adapt to your brokerage’s written policy:

• Ask the shipper for the freight’s original origin and final destination, not only the pickup and drop addresses.
• Read the carrier’s recorded operation and its authority status for the role it will take.
• If the movement is interstate and the carrier is intrastate only, do not treat a state certificate as a substitute for federal authority.
• If the freight is an exempt commodity, check the commodity before reading a missing MC number as a defect.
• Record the determination and who made it.
