183 Prices and Eligibility

1.0 Library Mail Prices and Fees

1.1 Prices

Library Mail prices are based on the weight of the piece without regard to zone.

1.2 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.

1.3 Library Mail Price Application

Library Mail 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 per addressed piece is that for an addressed piece weighing 1 pound.

1.4 Barcode Discount—Machinable Parcels

The barcode discount applies to Library Mail machinable parcels (see 101.3.3) that are included in a mailing of at least 50 pieces of Library Mail. The pieces must bear a correct, readable barcode for the ZIP Code shown in the delivery address as required by 708.5.0, Standards for Postal Routing Barcodes.

1.5 Library Mail Prices

[5-11-09] For barcode discount for single-piece, deduct $0.03 per parcel (machinable parcels only, 50-piece minimum). See Exhibit 1.5, Library Mail Prices.
