Commercial Mail: First-Class Mail Prices and Eligibility
1.5 Presort Mailing Fee
A First-Class Mail presort mailing fee must be paid once each 12-month period
at each office of mailing by any person or organization entering mailings at
automation or Presorted First-Class Mail prices. Payment of this fee does not
apply to qualified full-service mailings (under 705.23.3.1a.). 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.
1.6 Computing Postage for First-Class Mail
Determine single-piece weight and weight (postage) increment for each
addressed piece as prescribed in 1.7 and 1.2. For First-Class Mail, affix postage
to each piece under 234.2.2, or, for permit imprint mailings, multiply the number
of addressed pieces at each price increment (and in each price category, if
applicable) by the corresponding postage price, 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.
2.0 Content Standards for First-Class Mail
2.1 General
With the exception of restricted material as described in 601.8.0, any mailable
item may be mailed as First-Class Mail.
2.2 Bills and Statements of Account
Bills and statements of account must be mailed as First-Class Mail, Priority Mail
or Priority Mail Express and are defined as follows:
a. Bills and statements of account assert a debt in a definite amount owed by
the addressee to the sender or a third party. In addition, bills include a
demand for payment; statements of account do not include a demand for
payment. The debt does not have to be due immediately but may become
due at a later time or on demand. The debt asserted need not be legally
collectible or owed.
b. Bills and statements of account do not need to state the precise amount
due if they contain information that would enable the debtor to determine
that amount.

mailings includes one standard optical disc no larger than 12 centimeters in
diameter per mailpiece, the disc will not be considered to be rigid and a
nonmachinable surcharge will not be charged on either the outgoing piece or the
returned BRM or PRM piece as long as the disc is not put in a rigid container and
the envelope itself is not rigid. When a flat-size mailpiece weighing no more than
2 ounces in round-trip mailings includes one standard optical disc no larger than
12 centimeters in diameter, the mailpiece will be subject to the applicable price
for a 1-ounce First-Class Mail letter if the disc is not in a rigid container and the
envelope itself is not rigid and all other standards in 2.7 are met. The disc is not
considered to be rigid for purposes of the flexibility test in 201.4.3. BRM or PRM
pieces that meet the standards will be charged the applicable 1-ounce
First-Class Mail letter price for pieces that weigh no more than 2 ounces. For the
purpose of this standard, round-trip mailings are mailings entered under these
conditions:
a. The mailing is presented at a BMEU or other acceptance facility as a:
1. presort mailing at nonautomation machinable or automation First-Class
Mail letter prices; or
2. single-piece mailing using a permit imprint or as a presort mailing at
presort or automation First-Class Mail flats prices.
b. The outbound mailpieces are addressed to subscribers and include either a
BRM (under 505.1.0) or PRM (under 505.2.0) envelope designed for return of
the disc to the permit holder.
c. A sample of the return envelope is provided to the acceptance employee at
the time of mailing for verification that the mailing is designed for round-trip
purposes.
d. Returned BRM or PRM pieces must be picked up by the mailer at
