Definition:
Interstate move means transportation of goods in the United States which is between a place in a state and a place outside of that state (including a place outside the United States); or between two places in a state through another state or place outside of the United States.
Technically, there are about five different scenarios for interstate moves - see the pictures below.
If yours is an interstate move it will be governed by FMCSA rules and regulations.
Scenario 1: A move occurs between a place in a state and a place outside of that state (i.e., in another state or country). The move is still considered ''interstate'' even if other modes of transportation, such as plane or rail are involved in moving the goods as long as the goods cross a state line and involve a mover at any point, it is an interstate move, and at least the portion involving the mover is governed by FMCSA rules and regulations.
The moving truck or van does not have to physically cross a state line for it to be an interstate move. 
Scenario 2: Occurs between a place in a state and a place outside of the United States:

Scenario 3: The intent of the move can define whether the move is interstate. In this example, the move begins inside the state and goes to a warehouse (not the final destination) within the state. Nevertheless, since the move's destination is outside the state it is characterized as an interstate move.

Scenario 4: Occurs between two places in the same state if the shipment passes through a place outside the United States:

Scenario 5: Occurs between two places in the same state if the shipment passes through another state:
