The cost of mailing varies with each classification.

its aspect ratio (length divided by height) does not fall between 1 to 1.3 and 1 to 2.5 inclusive

There is an additional charge on each piece of mail that is found to be non-standard. In addition, pieces which are less than the following dimensions are non-mailable in the U.S. Postal Service and will be returned to you:
31/2" in height or 5" in length or .007" in thickness (thickness of a postcard)

B. First-Class Mail
Any mailable matter may be mailed as First-Class Mail up to and including 13 oz. The following examples are considered First-Class matter and must carry postage at First-Class, Priority, or Express Mail rates.

  • Matter wholly or partially handwritten or type-written (including identical copies prepared by automatic typewriter), originals or carbons, invoices (except when accompanying the matter to which they relate), postal cards, and post cards

Presort training is also available through UF Mail Services. For more information about the training, contact a University Postal Manager.

D. Priority Mail (not guaranteed)
All First-Class mail exceeding 13 oz. and not exceeding 70 lbs. is considered priority mail and at the option of the mailer, any mail weighing 13 oz. or less. There is no minimum weight limitation but there is a flat rate charged on mail weighing one lbs. or less.

The U.S. Postal Service provides free Priority supplies: cardboard and Tyvek envelopes, boxes, stickers and tape. If you need any supplies for your department, please call UF Mail Services Main Branch at 392-0629 or the Health Science Center Branch at 273-5022.

Use Priority Mail when two to three day service is desired. Discount rates are available for 300 or more pieces when using priority mail. Use Flat Rate Priority Envelopes when possible. These free envelopes allow any weight of material for the one lb. rate.

Global Express Mail is an extremely reliable and fast delivery service available from the U.S. Postal Service. It reaches all major markets in the U.S. and over 190 foreign countries. Global Express Mail provides shipment of letters, documents, and other mailable items and carries document reconstruction insurance at no additional cost. Also, merchandise is insured against loss, damage, or rifling up to $500 at no added charge. Additional insurance may be purchased with coverage up to $5,000. You may mail up to 70 lbs. This can be delivered seven days a week including holidays at no extra charge.

Do not place critical mail for this service in the internal mail system. In order to make that day’s mailing, mail for this service must be handed to a UF Mail Services clerk by 3:30 pm for that day’s delivery. Global Express Mail can also be placed in any Express Mailbox (one is available in the Reitz Union) or taken directly to a U.S. Post Office.

Domestic Overnight Delivery is guaranteed by the U.S. Postal Service (to most locations), and provides for a full postage refund if the item is not delivered on time.

International deliveries vary by country of destination. Delivery times average two to three business days to major business centers. However, items are not insured against delay in delivery since the U.S. Postal Service has no control over foreign delivery systems. Merchandise is insured against loss, damage, or rifling up to $500 at no added charge. Additional insurance may be purchased with coverage up to $5,000. Document reconstruction insurance is covered up to $500 maximum per shipment.

J. International Mail
Most items are mailable to foreign countries. However, there are certain restrictions. It is important that mailers contact UF Mail Services to determine the proper classification and documentation required.

If customs regulations are not followed and documentation is not exact, the item will be impounded by customs until the addressee makes arrangements for clearance and the payment of whatever duties required for the release of the item.
Customs rules are the same whether mail is sent by USPS or other couriers.

Customs Forms
Any printed matter or any mail over 16 oz. going outside of the U.S. must have a customs declaration.
