Effective September 8th, 2009, the USPS has implemented new tabbing rules for booklets. The definition of a booklet is a mail piece that consists of bound sheets or pages. Binding methods include perfect binding, saddle stitching (permanent fastening with at least two staples in the manufacturing fold), pressed glue and glue dots.

The maximum height for machinable and automated booklets is six inches and the maximum length can vary between 9 and 10 inches, depending on the booklet design. The minimum thickness for booklets is .009 and the maximum thickness is .25 inches, regardless of size. Thickness is measured at the spine of the mailpiece. The maximum weight for a booklet is still 3 ounces.

Tabs used to seal booklets must not have perforations. Generally, booklets will require three 1 tabs as closures. The larger, heavier type booklet is recommended to have 2-inch tabs. Glue dots or a continuous glue line may be used to seal some booklet designs.

Booklets that do not comply with the new standards will not be eligible for machinable or automation letter discounts. Non-machinable booklets will be assessed a surcharge (for First Class Mail), pay nonmachinable prices (for Standard/Non-Profit mail) or pay non-barcoded prices (for Periodicals).

Again these new changes express the desire of the USPS to improve mail processing efficiency and reduce equipment jams and mailpiece damage.

UH Postal Services has stocked some of the new non-perforated 1 tabs in preparation for the change. Our staff will be happy to work with your designers to ensure that any future mail pieces that may be designed in booklet format meet the new USPS mailing requirements.

An exhibit showing the different types of booklet design is included below. Please contact UH Postal Services with any questions you have on this new requirement.
