§375.407. Under what circumstances must I relinquish possession of a collect-on-delivery shipment transported under a non-binding estimate? — Inbound Citations

(d) For non-binding estimates, you must provide your reasonably accurate estimate of the approximate costs the individual shipper should expect to pay for the transportation and services of such shipments. If you provide an inaccurately low estimate, you may be limiting the amount you will collect at the time of delivery as provided in § 375.407.

(10) If the individual shipper requests additional services after the bill of lading has been issued, you must inform the individual shipper of the additional charges involved. You may require full payment at destination for these additional services and (unless you make only a partial delivery, in which case you must collect a prorated percentage of the original non-binding estimate as set forth in § 375.407(c) of this part) for up to 110 percent of the original non-binding estimate. If applicable, you also may require payment at delivery of charges for impracticable operations (as defined in your carrier tariff) not to exceed 15 percent of all other charges due at delivery. You must bill and collect from the individual shipper any applicable charges not collected at delivery in accordance with subpart H of this part.
