When a number of differently described articles are shipped as a mixed shipment, the charges on the shipment will be determined as follows:

1. Each article packaged separately and listed separately (on the bill of lading) by weight will be rated using its actual weight and applicable rate. Except, the total shipment weight will be used to satisfy any minimum weights. Any deficit weight will be rated at the lowest rate applicable to any article in the shipment.

2. When two or more different articles are in the same package, the applicable rate for the package will be the highest applicable for any article therein. All articles need not be specified if the highest rated article is shown with the following notation on the bill of lading: "and other articles rated same or lower" (RS or L).

3. When two or more different commodities, however packaged, are in the same shipment with only the total weight being shown, the applicable rate for the shipment will be per the class, rate or charge that is the highest for any article therein.
