133 Rates and Eligibility

1.0 First-Class Mail Rates and Fees

1.1 First-Class Mail Single-Piece Rate Application

The single-piece rates for First-Class Mail are applied as follows:

a. The card rate applies to a card meeting the applicable standards in 101.6.3, Cards Claimed at Card Rates.

b. The letter rate applies to any other First-Class Mail (letter, flat, and parcel) weighing 13 ounces or less that is not eligible for and claimed at the card rate.

1.2 Rate Computation for First-Class Mail

First-Class rates are charged per ounce or fraction thereof; any fraction of an ounce is considered a whole ounce. For example, if a piece weighs 1.2 ounces, the weight (postage) increment is 2 ounces. The minimum postage per addressed piece is that for a piece weighing 1 ounce.

1.3 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.

1.4 Rates for Cards

Cards meeting the standards in 101.6.3, Cards Claimed at Card Rates: $0.24 each.
