Motor carriers may write their own tariff, subscribe to a generic tariff service, or have an individual custom made tariff written for them by a legal professional. Any tariff must be written to comply with all applicable federal regulations. Since a motor carrier must only provide the exact services and prices as listed in the tariff, it is important that the tariff be made to match the services and prices that the motor carrier is providing or will provide. Be cautious of generic tariffs that may not exactly match the services and rates the motor carrier is offering. If a motor carrier uses a generic tariff which only allows for line haul charges based on weight of the property, then charging based upon cubic feet would be both a civil and criminal violation. Also, if a generic tariff does not contain provisions for charges for stairs, long carry, storage, etc., then the motor carrier who uses the generic tariff cannot charge the consumer shipper for those services.
