Buy America Act & Door Hardware: What Federal Project Specifiers Need to Know

Three separate federal statutes — plus one trade agreement framework — govern domestic content requirements for door hardware on government projects. The Buy American Act (1933), the Buy America Act (transportation), and the Build America Buy America Act (BABA, 2021) each apply to different project types with different thresholds. Getting the wrong rule into your Division 08 71 00 section, or citing the right rule but the wrong threshold, can stall project closeout and trigger contract disputes. This guide maps each law to the projects it actually covers, explains what the 55% manufactured-products threshold means for hardware specification, and provides sample specification language ready to adapt.

The Four Frameworks — Why the Acronym Soup Matters

Architects and specifiers working on publicly funded buildings regularly encounter the phrase “Buy America compliant” in project requirements — but that phrase can refer to at least three different laws depending on who is funding the project and what they are buying. Mixing up the statutes is not a technicality; it determines whether a product is permissible, whether a waiver is even available, and who has to apply for it.

The oldest rule is the Buy American Act of 1933 (41 U.S.C. §§ 8301–8305), which governs direct federal government purchases. When a federal agency buys door hardware through a GSA Schedule contract or a direct procurement, Buy American Act rules apply. The threshold is that end products must be "manufactured in the United States" with components that are also substantially all domestic — a test that has been interpreted to require roughly 50–55% domestic component cost under FAR Part 25.

The Buy America Act (transportation context) is a separate statute applying to highway and transit projects that use federal funds distributed through FHWA and FTA. Iron and steel must be 100% domestic. Manufactured products, which include door hardware, must meet a 55% domestic cost threshold. This rule has been in force for transportation infrastructure for decades and is enforced by the relevant operating administrations.

The newest layer is the Build America Buy America Act (BABA), enacted in November 2021 as Section 70901–70927 of the Infrastructure Investment and Jobs Act (IIJA, Public Law 117-58). BABA extends domestic preference requirements to all federally-funded infrastructure projects — not just transportation — including disaster recovery funds through FEMA, Economic Development Administration grants, and a wide range of other federal infrastructure programs. The manufactured-products threshold is 55% domestic manufacturing cost, matching the FTA/FHWA standard but now applying much more broadly.

The Trade Agreements Act (TAA) operates differently. Rather than requiring domestic manufacture, TAA creates a list of designated countries — trading partners with reciprocal government procurement agreements — whose products are treated as equivalent to US-made for federal procurement purposes. Taiwan is a TAA-designated country. Door hardware manufactured in Taiwan is TAA-compliant and eligible for GSA Schedule listing and direct federal procurement under FAR Part 25 exceptions.

The 55% Manufactured-Products Threshold — What It Actually Means

For manufactured products under BABA and Buy America (transportation), the compliance test is cost-based, not country-of-origin-based. The rule requires that, calculated across all components of the end product, at least 55% of the total cost of all components must come from components manufactured in the United States.

For a door hinge, the components include the hinge body castings, barrel pins, springs or hydraulic mechanism, fasteners, finish plating, and packaging. A US-assembled product using primarily imported components can fail the 55% test. Conversely, a product with a US-manufactured body and US-sourced springs that also incorporates a small imported hydraulic cartridge might still pass if the cartridge cost is below 45% of total component cost.

The practical implication for specifiers is that manufacturer compliance claims need to be specific. A statement that hardware is “manufactured in the USA” is not by itself a BABA certification. The required documentation is a Domestic Content Certification attesting to the 55% component threshold by cost, which the project sponsor submits as part of contract closeout.

Manufacturer Compliance Status Overview

For projects that trigger BABA compliance and where US-manufactured hardware is not preferred, the path is a project-level waiver — not a product substitution. Verify current production locations and domestic-content certifications directly with each manufacturer before final specification, as manufacturing footprints and supply chains change.

The following sample language is structured for the CSI MasterFormat Division 08 71 00 (Door Hardware) section. Adapt the applicable statute reference to match the funding source for your project. This is a starting point, not legal advice; have your specifications attorney review before use on actual contracts.

Waiver Process — The Project Sponsor's Responsibility

One of the most misunderstood aspects of BABA and Buy America compliance is who applies for waivers. Manufacturers cannot request waivers. Distributors cannot request waivers. The obligation rests with the project sponsor — the entity receiving the federal award — who must submit a waiver application to the awarding federal agency before procurement.

Three waiver categories are available under BABA. A non-availability waiver applies when no US-manufactured product meeting the specification is commercially available. A public interest waiver may be granted when the awarding agency determines that applying the domestic preference requirement is contrary to the public interest. An unreasonable cost waiver applies when the price premium for compliant domestic products is disproportionate to the project benefit. Threshold cost differentials and documentation requirements vary by agency.

FEMA published its BABA implementation framework in 2023, and OMB has issued guidance on consistent waiver processing across agencies. Both require that waivers be published for public comment before final approval, which adds lead time to the procurement schedule. Specifiers should flag the compliance question early — not at hardware submittal review — to allow project owners adequate time to pursue waivers if needed.

For compliance questions on fire-rated door assemblies that also carry NFPA 80 listing requirements, confirm that any substituted domestic-compliant hardware maintains its UL listing for the rated assembly. A BAA-compliant hinge that is not listed for the specific fire door is not an acceptable substitution. See related guidance on how many spring hinges a fire door requires and the ANSI/BHMA A156.17-2025 updated standards that affect Grade 1 self-closing hinges on rated assemblies.
