Chapter 3
CAUTION: Do not use envelopes made with glossy materials such as fliers, or Tyvek®
envelopes. Also do not use envelopes too fragile (such as air mail and onion skin envel-
opes) to pass through the feeder.
Shape Based Rating
The shape of a mailpiece (thickness, length, width) plays a large role in the pricing of First-
Class Mail®, Express Mail, and Priority Mail postage. Since May of 2007, the USPS® has
combined weight with shape to better align prices with processing costs. This is to ensure
that every type of mail covers its costs, i.e., Shape Based Rating or SBR.
When shape based rating is used, the mailing system determines the size and weight of the
mail and automatically selects the appropriate rate.
Shape based rating is available on systems with the WEIGH-ON-THE-WAY® (W-O-W®)
/Shape Based Rating module.
