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 January 2009, and ending June 2009 is 5 5/8 percent.
