That's right. It is an over statement.
In MN, tents fall under the same import laws as child toys. Child toys must have a level of fire retardant that greatly exceeds what most people would consider logical for camping. Basically, most normal tents can have a stove burning in them (note: this is not safe, don't do it) and they will not go up in flame if the flame touches the tent material for a period of time. In the case of BD, they have removed some, but not all, of this fire retardant to make it lighter. Because of this, they are no longer "safe children's toys" and cannot be imported into Minnesota.
That said, I do not know if the fire retardant is applied to the EPIC threads themselves or if is added as a coat to the EPIC after production. That is, I don't know if EPIC is inherently fire retardant or if BD coats the EPIC to make it fire retardant. Your EPIC jacket may not have any fire retardant if it is applied to the fabric rather than the thread.
