2 C.F.R. § 3485.220
(a) Covered transactions under this part—
(b) Specifically, a contract for goods or services is a covered transaction if any of the following applies:
(c) In addition to the contracts covered under 2 CFR 180.220(b) of the OMB guidance, this part applies to any contract, regardless of tier, that is awarded by a contractor, subcontractor, supplier, consultant, or its agent or representative in any transaction, if the contract is to be funded or provided by ED under a covered nonprocurement transaction and the amount of the contract is expected to equal or exceed $25,000. This extends the coverage of the ED nonprocurement suspension and debarment requirements to all lower tiers of subcontracts under covered nonprocurement transactions, as permitted under the OMB guidance at 2 CFR 180.220(c) (see optional lower tier coverage in the figure in Appendix A to Part 3485—Covered Transactions).
