1.6 Computing Postage for First-Class Mail

Determine single-piece weight and weight (postage) increment for each addressed piece as prescribed in 1.1 and 1.2. For First-Class Mail, affix postage to each piece or, for permit imprint mailings, multiply the number of addressed pieces at each rate increment (and in each rate category, if applicable) by the corresponding postage rate, add the unrounded products, and round off the total postage to the nearest whole cent.

1.7 Determining Single-Piece Weight

To determine single-piece weight in any mailing of nonidentical-weight pieces, weigh each piece individually. To determine single-piece weight in a mailing of identical-weight pieces, weigh a sample group of at least 10 randomly selected pieces and divide the total sample weight by the number of pieces in the sample. Express all single-piece weights in decimal pounds rounded off to four decimal places.
