1. Single shipments which consist of articles subject to only one class or commodity rate will be charged at the actual or authorized estimated weight and at the class or commodity rate applicable, subject to the minimum charge in the appropriate minimum charge item in tariffs making reference hereto.
2. Single shipments which consist of articles subject to two or more different rates, when articles subject to such different rates are separately packaged, will be charged at the actual or authorized estimated weight, and at the class or commodity rate applicable to each, subject to the minimum charge in the appropriate minimum charge item in tariffs making reference hereto.
3. Where different scales of rates are provided for shipments of different weights, apply on each article the rate which would apply on that article if such article were tendered as a straight shipment weighing the same as the aggregate weight of the mixed shipment. Any deficit between the actual weight of the shipment, and the weight provided for the next lower scale of rates, will be charged for at the lowest rate applicable to any article in the shipment.
4. When two or more commodities for which different ratings are provided, are shipped as a mixed shipment without actual weights being obtainable for the portions shipped under the separate ratings, charges for the entire shipment will be computed at the class or commodity rate applicable to the highest classed or rated commodity contained in such mixed shipment. The minimum weight shall be the highest provided in any of the rates used in computing the charges. In the event a lower charge results by considering such commodities as if they were divided into two or more separate shipments, such lower charge shall apply.
