(a) The preceding sections of this part, to the extent they reflect remedies or procedures prescribed by the Debt Collection Act of 1982 and the Debt Collection Improvement Act of 1996, such as administrative offset, use of credit bureaus, contracting for collection agencies, and interest and related charges, do not apply to debts arising under, or payments made under, the Internal Revenue Code of 1986, as amended (26 U.S.C. 1 et seq.); the Social Security Act (42 U.S.C. 301 et seq.), except to the extent provided under 42 U.S.C. 404 and 31 U.S.C. 3716(c); or the tariff laws of the United States. These remedies and procedures, however, may be authorized with respect to debts that are exempt from the Debt Collection Act of 1982 and the Debt Collection Improvement Act of 1996, to the extent they are authorized under some other statute or the common law.

(b) Claims arising from the audit of transportation accounts pursuant to 31 U.S.C. 3726 will be determined, collected, compromised, terminated or settled in accordance with regulation published under the authority of 31 U.S.C. 3726 (see 41 CFR part 101-41, administered by the Director, Office of Transportation Audits) and are otherwise exempted from this part.
