Payment of a presort mailing fee is required once each 12-month period at each office of mailing by any person or organization entering mailings at automation or Presorted First-Class Mail or any presorted First-Class Package Service prices. Payment of one fee allows a mailer to enter mail at all those prices. Persons or organizations paying this fee may enter mail of their clients as well as their own mail. The fee may be paid in advance only for the next 12 months and only during the last 60 days of the current service period. The fee charged is that which is in effect on the date of payment.
Affix postage to each piece or, for permit imprint mailings, multiply the number of pieces at each price increment by the corresponding postage price, add the unrounded products (amounts), and round off the total postage to the nearest whole cent.
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.
