(1) the following matters if they occur under the authority of the principal carrier:
(A) a rate for the transportation of household goods;
(B) an access, terminal, storage, or other charge incidental to the transportation of household goods; or
(C) an allowance relating to the transportation of household goods; or
(2) ownership of the carrier by the agent or membership on the board of directors of the carrier by the agent.
(b) An agent under Subsection (a) may itself be a motor carrier required to register under Subchapter B.

(c) The department by rule may exempt a motor carrier required to register under Subchapter B from Chapter 15, Business & Commerce Code, for an activity relating to the establishment of a joint line rate, route, classification, or mileage guide.
(d) A motor carrier that is required to register under Subchapter B and that transports household goods, or an agent of the carrier, may enter into a collective ratemaking agreement with another motor carrier of household goods or an agent of that carrier concerning the establishment and filing of maximum rates, classifications, rules, or procedures. The agreement must be submitted to the department for approval.
(e) The department shall approve an agreement submitted under Subsection (d) if the agreement provides that each meeting of parties to the agreement is open to the public and that notice of each meeting must be given to customers who are multiple users of the services of a motor carrier that is a party to the agreement. The department may withhold approval of the agreement if it determines, after notice and hearing, that the agreement fails to comply with this subsection.
