The USPS non-machinable surcharge is applied to letters and envelopes when they can’t be automatically processed. Essentially, you are charged for the use of certain machines to assist with the sorting and separating. Being larger than the machine is able to sort into the appropriate pile means your package will be bumped up to the next class of letter or package, which often costs more money.
If you are sending an odd shaped package (too large or with variable shapes) you’ll want to use the proper postage so you don’t get charged additional fees.
USPS Machinable Criteria
Some of the main criteria you want to watch out for are:
- The aspect ratio (length divided by height) must be at correct.
- The package must be kept in the proper shipping container (often boxes, letters, or envelopes)
- The package shouldn’t have any pieces dangling off it such as rope, clasps, or locks.
- The package typically must be of uniform size (Flat rate boxes are great examples of this. Learn more.)
- The delivery address must be put in it’s appropriate place.
By avoiding these points, you save the USPS time which in return can save yourself money! Learn how ShippingEasy helps you save even more money on USPS rates.
- Is the package a strange shape?
- Does this package have improper postage or shipping address in a hard to see location?
- Is the package in an odd container?
- Can anything on my package get caught or tangled on other things?
If you can answer “Yes” to any of those you may have a non-machinable package that will incur an additional fee.
