The USPS® Supplier Disagreement Resolution Official (SDR Official) resolves business disagreements that arise during the purchasing process, and that cannot be resolved between the supplier and the Postal Service™ contracting officer. This expedited and business-like disagreement-resolution process replaces the Postal Service’s protest procedures, and applies to business disagreements concerning the award of a Postal Service contract and related matters; it does not apply to disputes arising under the Contract Disputes Act, non-renewal of transportation contracts or with respect to disputes about debarment, suspension and ineligibility. The SDR Official’s decisions are final and binding on all parties.

Who the SDR Officials Are
The Postal Service SDR Officials are Mark Guilfoil, Manager, Supply Management Infrastructure, Supply Management and Robert D’Orso, Manager, Policy, Compliance & Audit, Supply Management Infrastructure, Supply Management.

How to Lodge a Business Disagreement
Complete instructions on how to lodge a business disagreement, including what constitutes a disagreement, who may file a disagreement, and applicable time limits, are available in the Postal Service purchasing regulations codified at 39 CFR Section 601. These regulations may be accessed via the Electronic Code of Federal Regulations (e-CFR).
