SUPPLEMENTARY INFORMATION: Background Pursuant to 19 U.S.C. 1505 and Treasury Decision 85-93, published in the 
                    **Federal Register**
                     on May 29, 1985 (50 FR 21832), the interest rate paid on applicable overpayments or underpayments of customs duties must be in accordance with the Internal Revenue Code rate established under 26 U.S.C. 6621 and 6622. Section 6621 was amended (at paragraph (a)(1)(B) by the Internal Revenue Service Restructuring and Reform Act of 1998, Pub. L. 105-206, 112 Stat. 685) to provide different interest rates applicable to overpayments: one for corporations and one for non-corporations. The interest rates are based on the Federal short-term rate and determined by the Internal Revenue Service (IRS) on behalf of the Secretary of the Treasury on a quarterly basis. The rates effective for a quarter are determined during the first-month period of the previous quarter. In Revenue Ruling 2005-62, the IRS determined the rates of interest for the calendar quarter beginning October 1, 2005, and ending December 31, 2005. The interest rate paid to the Treasury for underpayments will be the Federal short-term rate (4%) plus three percentage points (3%) for a total of seven percent (7%). For corporate overpayments, the rate is the Federal short-term rate (4%) plus two percentage points (2%) for a total of six percent (6%). For overpayments made by non-corporations, the rate is the Federal short-term rate (4%) plus three percentage points (3%) for a total of seven percent (7%). These interest rates are subject to change for the calendar quarter beginning January 1, 2005, and ending March 31, 2005. For the convenience of the importing public and Customs and Border Protection personnel the following list of IRS interest rates used, covering the period from before July of 1974 to date, to calculate interest on overdue accounts and refunds of customs duties, is published in summary format.
