USPS testing new standards for ‘slim jim’ catalogs
The U.S. Postal Service is preparing to test new standards around letter-size booklets, also known as “slim jim” catalogs. As more catalogers may switch to the lower-priced format in light of the current rate increase, the agency fears these slim jims may jam the agency’s delivery bar code sorters.
The USPS, as a result, is cautioning catalogers who may be considering switching to a slim-jim format to put those plans on hold until the standards are set. Testing will begin in about six months and could result in revised specifications for such mail pieces.
Slim jims measure 6.125 inches by 11.5 inches. The USPS considers them folded self-mailers and booklets. If they weigh 3 ounces or less and are tabbed, they are the largest size qualifying for letter-rate postage, which is significantly lower than recently increased Standard Mail flats postage.
Under the postal rates that go into effect today, mailers could save about 10 cents per book in postage by switching from a Standard Mail flat size that weighs less than 3 ounces.
Slim jims also could be mailed under the Heavy Letter subclass, which includes catalogs weighing more than 3 ounces and up to 3.5 ounces that are placed in envelopes. This subclass of mail qualifies for a hybrid rate that is still significantly below the rates for Standard Mail flats.
Some mailers question whether or not the change could affect response rates negatively.
The USPS has said there are not many slim jims in the systems now, and when they do appear in USPS facilities, postal employees will put them through the more robust AFSM-100 flats sorter as opposed to the delivery bar code sorters, which handle letter mail. However, to get the lower rates, they will have to be able to go through the delivery bar code sorter machine.
