What is the weight limit for packages to be charged a Balloon Rate?

The Balloon Rate is a pricing structure used by USPS for packages that are large in size but light in weight. To qualify for the Balloon Rate, a package must weigh under 20 pounds. This pricing helps to accommodate packages that take up more space in transport but do not weigh much, balancing the cost between size and weight. Therefore, a package that is 20 pounds or over does not qualify for Balloon Rate pricing. Instead, heavier packages will be subject to different pricing structures based on their weight and dimensions.
