Understanding OMB Guidance on Buy American Waivers for IT Infrastructure
Introduction: Why Buy American Compliance Matters for IT Infrastructure Procurement
Federal agencies, defense contractors, and federally funded educational institutions procuring IT infrastructure—structured cabling, fiber optic systems, enclosures, racks, and data center power equipment—must navigate an evolving landscape of domestic content requirements. The Office of Management and Budget (OMB) issues guidance implementing the Buy American Act (41 U.S.C. §§ 8301–8305), the Build America, Buy America Act (BABA, enacted under the Infrastructure Investment and Jobs Act of 2021, P.L. 117-58), and associated Federal Acquisition Regulation (FAR) Part 25 provisions. Understanding when and how waivers apply is essential for compliant, technically sound procurement decisions.
Statutory Framework: Buy American Act vs. BABA
The Buy American Act (BAA) applies to direct federal agency purchases of supplies and construction materials. The Build America, Buy America Act extends domestic content requirements to federally funded infrastructure projects, including broadband and network infrastructure grants administered through programs such as BPIL and NTIA. Under FAR 25.101, end products must be domestic—meaning manufactured in the United States with all components mined, produced, or manufactured domestically, or meeting a cost threshold. OMB's March 2022 guidance (M-22-11) strengthened domestic content thresholds, raising the component cost test from 55% to 60% as of January 2022, with a planned increase to 65% in 2024 and 75% by 2029.
"Agencies must apply a rigorous analysis before granting a nonavailability or unreasonable cost waiver. The preference for domestic products in infrastructure procurement is not merely procedural—it reflects a policy determination that supply chain resilience and domestic manufacturing capacity are national security interests."
Types of Buy American Waivers Available to Procuring Agencies
OMB guidance and FAR Part 25 recognize three principal waiver categories applicable to IT infrastructure components:
- Nonavailability Waiver: Granted when a domestic product of satisfactory quality and sufficient quantity is not reasonably available. Agencies must document market research demonstrating the absence of compliant domestic sources.
- Unreasonable Cost Waiver: Applicable when the cost of a domestic end product is unreasonable compared to a foreign product. Under FAR 25.105, the cost differential threshold is generally 20% for large businesses and 30% for small businesses.
- Public Interest Waiver: Issued by the head of an agency or OMB when domestic preference would be inconsistent with the public interest, including treaty obligations under the World Trade Organization Government Procurement Agreement (WTO GPA).
For IT infrastructure specifically, nonavailability waivers are most commonly invoked for specialized fiber optic components, advanced cable management hardware, and high-density cabling assemblies where domestic manufacturing capacity may be limited relative to program scale.
Technical Specifications That Drive Waiver Decisions
A common trigger for nonavailability waiver requests is a performance specification that only a limited set of manufacturers—domestic or foreign—can satisfy. Network engineers and procurement officers must therefore understand which technical requirements are standards-mandated versus agency-specific, because overly restrictive specifications can invite protest and scrutiny from OMB.
Key standards governing IT infrastructure performance include:
- ANSI/TIA-568.2-D (Balanced Twisted-Pair Telecommunications Cabling): Defines channel insertion loss, return loss, and NEXT for copper cabling categories. Cat6A channels must support 10GBASE-T per IEEE 802.3an to 100 meters with a minimum 500 MHz bandwidth requirement.
- ANSI/TIA-942-B (Telecommunications Infrastructure Standard for Data Centers): Mandates specific structured cabling topologies, redundancy tiers (Tier I–IV), and requires that fiber optic backbone cabling support link loss budgets consistent with installed transceivers.
- ISO/IEC 11801-1:2017: The international equivalent governing generic cabling for customer premises, widely referenced in multinational federal programs and NATO facility construction.
- OM3 and OM4 multimode fiber: Per TIA-492AAAC and TIA-492AAAD, OM3 supports 10 Gbps Ethernet to 300 meters and OM4 to 400 meters at 850 nm using VCSEL sources. OM5 (per TIA-492AAAE) extends wideband multimode performance across 850–953 nm to support emerging shortwave division multiplexing (SWDM) applications.
- NEC Article 800 and 770: The National Electrical Code governs plenum, riser, and general-purpose cable flame ratings (CMP, CMR, CM), which affect both product eligibility and installation compliance in federally occupied buildings.
Waiver Documentation Requirements for Structured Cabling and Fiber Projects
When an agency determines that a waiver is necessary, OMB guidance requires that the waiver package include: a technical justification citing the applicable performance standard (e.g., TIA-568.2-D channel loss budget of ≤ 11.4 dB for a Cat6A permanent link at 100 MHz), documented market research results, price analysis supporting unreasonable cost findings, and a determination signed by the appropriate authority. For BABA-covered broadband infrastructure projects, the waiver request must also be posted to SAM.gov for public comment under the April 2022 OMB Implementation Guidance.
"Specifications should be written to the performance standard, not to a proprietary product. When agencies write requirements around a named brand's physical characteristics rather than TIA or ISO/IEC performance outcomes, they inadvertently create the conditions for a waiver request that could have been avoided."

Practical Guidance for IT Procurement Officers
To minimize waiver risk and maintain procurement defensibility, agencies and their technology distributors should adopt the following practices:
- Write performance-based specifications referencing TIA-568.2-D, ANSI/TIA-942-B, and IEEE 802.3 channel requirements rather than brand-specific physical attributes.
- Conduct early market research using GSA Advantage, SAM.gov, and distributor catalogs to identify domestic-manufactured or BABA-compliant cabling, fiber, and enclosure options before solicitation.
- Document insertion loss budget calculations (e.g., a 10GBASE-SR link over OM4 fiber carries a maximum channel attenuation of 2.9 dB per IEEE 802.3ae at 850 nm) to justify whether domestic alternatives meet mission-critical performance thresholds.
- Engage WBE/EDWOSB-certified distributors early in the acquisition cycle to leverage set-aside vehicles and confirm domestic content of inventory prior to submitting a waiver request that may be avoidable.
- For NEC Article 770-compliant fiber optic installations in federal buildings, verify that domestically sourced plenum-rated (OFNP) cables meet both the flame test requirements and the optical performance specs for the specified OM3, OM4, or OM5 classification.
Conclusion
OMB's evolving Buy American guidance reflects a sustained policy commitment to domestic manufacturing resilience that directly affects how agencies specify, source, and document IT infrastructure purchases. By grounding procurement decisions in recognized performance standards—TIA-568.2-D, ANSI/TIA-942-B, ISO/IEC 11801, IEEE 802.3, and NEC—and by conducting rigorous pre-solicitation market research, agencies can reduce reliance on waivers while meeting mission-critical technical requirements. Understanding the distinction between the Buy American Act and BABA, the applicable domestic content thresholds, and the documentation requirements for each waiver type is foundational to compliant, defensible federal IT infrastructure procurement.
