483 Prices and Eligibility

1.0 Library Mail Prices and Fees

1.1 Price Application

Postage is based on the price that applies to the weight (postage) increment of each addressed piece.

1.2 Library Mail Price Application

The Library Mail price is charged per pound or fraction thereof; any fraction of a pound is considered a whole pound. For example, if an item weighs 4.225 pounds, the weight (postage) increment is 5 pounds. The minimum postage price per addressed piece is that for an addressed piece weighing 1 pound.

1.3 Library Mail Presorted Prices

For prices, see Notice 123-Price List.

1.4 Mailing Fee

A mailing fee must be paid once each 12-month period at each Post Office of mailing by or for any person who mails at the Presorted Library Mail prices. For mail manifested using the Electronic Verification System (eVS) under 705.2.9, only one annual mailing fee for Presorted Library Mail prices, paid at the Post Office where the eVS permit imprint account is held, is required regardless of the number of Postal Service facilities where mailings are verified. 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 in effect on the date of payment.

1.5 Computing Postage for Library Mail

1.5.1 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.

1.5.2 Computing Postage for Affixed Postage

For each piece, affix the postage for the weight increment (including any discounts). To calculate the total postage for the mailing, add all of the affixed postage amounts for each piece.

1.5.3 Computing Postage for Permit Imprint

To compute the total postage for a mailing, for each weight increment, multiply the number of pieces by the applicable price per piece. Round each product off to four decimal places. Add the products and round up the total postage to the nearest whole cent.
