It is the best-priced service for items up to 15.999 oz, based on weight (rounded up to 4 oz, 8 oz, 12 oz, and 15.999 oz) and zone (distance). Packages greater than 15.999 oz are charged by the pound up to 70 lbs (rounded up). Pay for postage using stamps, a self-service kiosk, Click-N-Ship, or at a Post Office. Includes forwarding, undeliverable as addressed (UAA), and return to sender (RTS) at no additional cost.

The service is the primary option for sending hazardous materials (HAZMAT) that are only mailable using Ground Transportation. Weight, Size, & Shape Requirements: Large First-Class Mail envelopes are treated as packages if they are more than 15 inches long, 12 inches high, or 3/4 inch thick; rigid (can't bend); or not uniformly thick (lumpy). Price tiers for packages up to 15.999 oz are: up to 4 oz; up to 8 oz; up to 12 oz; and up to 15.999 oz. Items must be rounded up to the nearest tier. Items over 15.999 oz round up to 1 lb and pay pound-rate prices. Maximum weight is 70 lbs. Maximum combined length and girth (distance around the thickest part) is 130 inches. Additional Package Fees apply for large and lightweight packages, nonstandard sizes, shapes, or materials, and perishable items. Dimensional (DIM) weight rates apply to large, lightweight packages larger than 1 cubic foot (1,728 cubic inches): multiply Length x Width x Height and divide by 139 to get DIM weight in pounds. Any fraction of an inch must be rounded up to the next whole inch. If DIM weight exceeds actual package weight, the DIM weight price applies. A dimension-noncompliance fee applies if dimensions are omitted or inaccurate. Nonstandard fees vary: packages between 22 and 30 inches long add $4.50; more than 30 inches long add $10.00; more than 2 cubic feet add $21.00; nonstandard shape or material adds $4.00. A Live Animal & Perishable Handling Fee of $7.50 applies for packages with live animals or perishable items like food or plants. A HAZMAT Handling Fee of $0.00 applies for hazardous materials shipments. Specific regulations and standards apply for mailing restricted, prohibited, and hazardous materials, including cigarettes and smokeless tobacco. Military Post Office (APO/FPO/DPO) shipments pay domestic prices but require a customs form and have specific restrictions.
