COTS Items in Federal Procurement: Buy American Waiver and Section 889

Commercial off-the-shelf items in federal procurement are standard commercial products the government buys unmodified, and qualifying a product as COTS unlocks a package of regulatory shortcuts: procurement under FAR Part 12, exemption from certified cost or pricing data, warranty terms that mirror commercial practice, and a waiver of the Buy American Act’s domestic component test for most product categories. Federal law actually requires agencies to prefer commercial and COTS items over custom-built alternatives whenever practicable.¹ The catch is that the label is defined narrowly, and losing it (or misrepresenting it) has real consequences.

What Counts as a COTS Item

The Federal Acquisition Regulation sets a three-part test. The item must be a commercial product, sold in substantial quantities in the commercial marketplace, and offered to the government without modification in the same form sold to other buyers.²

“Substantial quantities” is where most vendors stumble. A product sold to a handful of specialized industrial clients probably does not meet it. The item needs to move through ordinary commercial distribution channels in volumes that reflect genuine demand from public or non-governmental buyers.

“Without modification” is equally strict. Altering a product to meet government specifications strips its COTS status. Minor cosmetic changes that do not affect physical characteristics or functional capabilities are generally permissible, but any redesign or reconfiguration to satisfy a government-unique requirement drops the product into the broader commercial product category or into the custom-development track with heavier regulatory overhead.

Bulk cargo is excluded outright. Agricultural products, petroleum products, and similar commodities shipped in large undifferentiated quantities do not qualify no matter how widely they are sold.² The COTS designation is built around discrete, identifiable supply items, not raw materials traded as bulk commodities.

Products that come close but miss the definition may still qualify as commercial products under FAR Part 12, which carries many of the same benefits, though not all of the COTS-specific exemptions.

The Exemptions Vendors Gain

No Certified Cost or Pricing Data

On larger federal deals, contractors normally must submit certified cost or pricing data under the Truth in Negotiations Act, which means opening internal cost structures, overhead rates, and profit margins to government review. Commercial products, including COTS items, are exempt.³ Contracting officers evaluate price reasonableness through market comparisons, catalog pricing, and historical sales data instead. For vendors who guard proprietary pricing information, this exemption alone can make federal contracting viable.

Streamlined Procurement Under FAR Part 12

All COTS items are acquired under FAR Part 12, the framework for commercial products.⁴ Solicitations are simpler, evaluation typically comes down to technical capability, price, and past performance, and contracting officers can combine the public notice and solicitation into a single document. Timelines from opportunity posting to award are shorter than under traditional procurement.

COTS items receive additional exemptions on top of the commercial product baseline. FAR 12.505 lists laws that do not apply to COTS acquisitions, including certain cost accounting standards that would otherwise require government-specific accounting systems.⁵ This is the lightest regulatory touch in federal procurement.

Commercial Warranty Terms

The government does not impose unique warranty requirements on COTS items. Contracting officers must accept at least the same warranty terms the vendor offers to commercial customers, including any available extended warranties.⁶ If the standard commercial warranty covers defects for one year, that same warranty applies to the government purchase. Solicitations may specify minimum warranty durations when justified by intended use, but parity with commercial terms is the baseline.

Buy American Act: The COTS Waiver

The Buy American Act requires the federal government to prefer products manufactured in the United States.⁷ For most manufactured end products, at least 65 percent of component costs must come from domestic sources through 2028, rising to 75 percent starting in 2029.⁸ Meeting that threshold requires detailed component-level cost tracking that is expensive and often impractical for products assembled from globally sourced parts.

COTS items get a substantial break. The domestic content test is waived entirely for most COTS products.⁸ A vendor only needs to show that the final product qualifies as a domestic end product. The origin of individual internal components does not matter.

The Iron and Steel Carve-Out

Products that consist wholly or predominantly of iron or steel do not receive the waiver. For those items, the cost of foreign iron and steel must remain below 5 percent of the cost of all components, even if the product otherwise qualifies as COTS.⁸ The one exception within the exception is COTS fasteners such as bolts, screws, and nuts, which remain exempt from the iron and steel restriction. Vendors selling steel-predominant products should not assume the COTS label solves their Buy American compliance problem.

Trade Agreements Act Thresholds

Once a contract’s estimated value hits certain dollar thresholds, the Trade Agreements Act can override Buy American restrictions for products from designated countries. Thresholds vary by agreement. For 2026, the WTO Government Procurement Agreement threshold is $174,000 for supply contracts, while some bilateral free trade agreements kick in as low as $100,000 for South Korea and $50,000 under the Israeli Trade Act.⁹ Products from TAA-designated countries are treated as domestic goods for these above-threshold acquisitions.

The designated list is extensive and covers most of Europe, Canada, Mexico, Australia, Japan, South Korea, and dozens of developing nations.¹⁰ China, Russia, and India are not on it. Products manufactured or substantially transformed in a non-designated country face real eligibility problems on larger contracts. Products sold through the GSA Multiple Award Schedule are subject to TAA requirements regardless of contract value.

How Vendors Actually Sell COTS Items

The path in depends on dollar value and how the agency plans to buy.

Micro-Purchases and Simplified Acquisitions

Below the $15,000 micro-purchase threshold, agencies can buy COTS items with a government purchase card with almost no competitive process, and vendors do not need a federal contract to receive these orders. Between $15,000 and the $350,000 simplified acquisition threshold, agencies use streamlined competitive procedures with lighter documentation than a full procurement.¹¹ These lower-value transactions are where many COTS vendors first enter the federal market.

GSA Multiple Award Schedule

For sustained federal sales, the GSA Multiple Award Schedule is the primary vehicle. MAS contracts are long-term, governmentwide agreements where vendors list commercial products at pre-negotiated prices, and federal, state, local, and tribal agencies can purchase directly with minimal additional competition.¹² Getting on schedule requires submitting an offer to GSA with commercial pricing data, catalog documentation, and evidence of past commercial sales. Evaluation can take several months.

Once on schedule, vendors respond to agency needs through GSA eBuy, where agencies post specific requirements and request quotes from schedule holders. Open-market opportunities appear on SAM.gov. Each platform has its own submission requirements, and missing a technical detail can disqualify an otherwise competitive offer.

Proving Commerciality and Price Reasonableness

Whatever the path, vendors need documentation showing the product is genuinely commercial and the offered price is fair. A current commercial price list or public catalog is the starting point. Sales records showing substantial transactions with non-government buyers provide the objective proof contracting officers and auditors look for. Keep this repository ready rather than assembling it when an opportunity appears.

Contracting officers verify price reasonableness by comparing the government offer to commercial pricing. If the government pays the same as or less than a comparable commercial buyer, the analysis is straightforward. Offering the government a different pricing structure than commercial customers can trigger requests for additional cost data and slow the procurement.

Section 889: A COTS Item Can Still Be Barred

A COTS item can meet every commercial and pricing requirement and still be ineligible if it contains prohibited telecommunications or surveillance components. Section 889 of the National Defense Authorization Act for Fiscal Year 2019 bars agencies from buying any equipment or system that uses covered telecommunications equipment as a substantial or essential component.¹³

The prohibition targets equipment produced by five Chinese companies (Huawei Technologies, ZTE Corporation, Hytera Communications, Hangzhou Hikvision Digital Technology, and Dahua Technology) along with their subsidiaries and affiliates. It reaches further than the contract itself. Agencies cannot contract with any company that uses covered equipment anywhere in its operations, even if the prohibited equipment has nothing to do with the federal work.¹³

Vendors certify compliance through representations in the System for Award Management. This is not a formality. Companies have lost contracts and faced investigations after certifying compliance and later being found to have covered equipment in their supply chain or internal IT infrastructure. Audit your own operations and supply chain before pursuing federal sales.

Penalties and the MAS Price Reductions Trap

Misrepresenting COTS status is not an administrative slip. A false certification to gain the regulatory benefits above can be pursued under the False Claims Act, with a civil penalty for each false claim (the statutory range of $5,000 to $10,000 per violation is adjusted annually for inflation and is now substantially higher) plus three times the damages the government sustained.¹⁴ A vendor who cooperates fully and self-reports within 30 days of discovering the violation may face reduced damages of two times the government’s loss, but only if no investigation has already begun.

The Price Reductions Clause

Vendors on GSA Multiple Award Schedule contracts carry an ongoing obligation that catches many companies off guard. The Price Reductions Clause requires notification of any price reduction given to the commercial customer category that formed the basis of the GSA contract award. Notice must reach the contracting officer within 15 calendar days of the effective date of the reduction.¹⁵

The trigger is broader than across-the-board price cuts. Revising a commercial catalog to lower prices, granting more favorable discounts than those in the original schedule offer, or giving special deals that change the price relationship between the government and the basis-of-award customer all activate the clause.¹⁵ When triggered, the vendor must extend the same reduction to government buyers for the same period. Failure to track and report these reductions is one of the most common audit findings on GSA schedule contracts, and a pattern of misses can turn into an overbilling investigation.
