Quick Service Guide 401Discount ParcelsPhysical Standards for Discount ParcelsJuly 2007 Overview
Measuring Length Plus Girth (401.1.0)For parcels, length is the measurement of the longest dimension and girth is the distance around the thickest part (perpendicular to the length). Except for Parcel Post, no mailpiece may measure more than 108 inches in length and girth combined. Parcel Post pieces measuring over 108 inches but not more than 130 inches in combined length and girth are mailable at the applicable oversized rate (453.1.0).
The Postal Service classifies parcels as machinable parcels, irregular parcels, or outside parcels. Machinable Parcels (401.1.5)If you prepare your discount parcels so that they can be processed on Postal Service equipment, your mail is "machinable." Machinable parcels must meet specific standards for size, shape, content, and weight. Minimum weight: 6 ounces (3.5 ounces for parcels prepared under 401.1.5.2). Maximum weight: 35 pounds (25 pounds for books and other printed matter). Lower weight limits apply to First-Class Mail, Standard Mail, and Bound Printed Matter. Dimensions: Soft goods wrapped in paper or plastic bags and enveloped printed matter are machinable only if all packaging standards in 601.2.0 are met.
Irregular Parcels (401.1.6)Irregular parcels include parcels that do not meet the dimensional criteria of machinable parcels and other parcels that cannot be processed by parcel sorters, including:
Outside Parcels (401.1.7)Outside parcels exceed any of the maximum dimensions for machinable parcels. This category also includes certain high-density items, cartons containing more than 24 ounces of liquids in one or more glass containers, cartons containing 1 gallon or more of liquid in metal or plastic containers, and items in 401.1.7.
First-Class Mail Parcels (401.2.1)Maximum weight: 13 ounces. Unless prepared in 5-digit/scheme containers or paid at a single-piece rate, presorted parcels are subject to a $0.05 surcharge if any of the following apply: See Quick Service Guide 430, First-Class Mail Presorted Parcels.
