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. Except for Critical Mail and mailers using eVS, express all single-piece weights in decimal pounds rounded off to two decimal places. For Critical Mail, express single-piece weights in decimal pounds rounded off to four decimal places. Mailers using eVS may round off to four decimals, and eVS will automatically round to the appropriate decimal place. If a customer is using a manifest mailing system, the manifest weight field must be properly completed by adhering to the rules relative to the specific manifest.
Determine weight increment for each piece and pay postage under 324.1.0. For permit imprint mailings, multiply the number of addressed pieces at each weight increment by the corresponding postage price.
