Interest Rate on Contract Claims

The Postal Service™ periodically publishes in the Postal Bulletin the interest rate payable on a claim decided in a supplier’s favor, under the Contract Disputes Act of 1978. This rate also applies for late payments to suppliers under the Prompt Payment Act, as amended.

The interest rate effective for the 6-month period beginning July 1, 2008, and ending December 31, 2008, is 5 1/8 percent.
