Selling to National Labs vs. Federal Agencies: What Changes

You already know the agency path. You hold a SAM.gov registration, you watch solicitations, and you write to the Federal Acquisition Regulation (FAR). A national laboratory runs differently, and the difference starts with who the buyer is.

Most Department of Energy (DOE) laboratories are operated by a private company under a management and operating (M&O) contract. When a lab buys from you, that operating company is the buyer, and it buys under its own purchasing system, approved by DOE. DOE’s regulations say these contractor purchases are not federal procurements and are not directly subject to the FAR. Four things change as a result: where you find work, how you register, what happens if you lose, and which rules still reach your contract.

The buyer is the lab’s operating contractor

Federal agencies buy directly. A contracting officer at the agency solicits, evaluates, and awards, and the award is a prime contract with the government.

At a lab, you receive a subcontract or purchase order from the M&O contractor. Los Alamos and Sandia both work this way. DOE’s M&O contracting rules tell that contractor to use effective competitive techniques and to award purchases under policies its DOE contracting officer has approved. The objective written into the regulation is best value for the work the lab does.

Not directly subject to the FAR does not mean unregulated

This is the part that trips up experienced agency sellers. The lab contractor must run a formal, documented purchasing system that meets standards modeled on FAR subpart 44.3, and DOE keeps oversight in three specific ways:

1. DOE can require the contractor to submit any or all subcontracts or purchases for approval, at any time.
2. DOE conducts periodic appraisals of the contractor’s whole purchasing function.
3. Substantive changes to the written purchasing system need the DOE contracting officer’s approval first.

In practice, a lab buy can look familiar and still follow a different rulebook. Read each solicitation on its own terms rather than assuming FAR clauses.

Agency buying and lab buying, side by side

Seven differences matter most. The two that cause the most surprises are the portal (SAM.gov versus a separate registration at each lab) and protest rights (GAO versus almost none).

	Federal agency	National lab (M&O)
Buyer	The agency’s contracting officer	The M&O contractor that runs the lab
What you receive	Prime contract with the government	Subcontract or purchase order with the lab contractor
Governing rules	FAR (48 CFR)	Contractor’s own purchasing system under DEAR Part 970, DOE-approved, built to FAR subpart 44.3 standards
Where opportunities post	SAM.gov	Each lab’s own portal. Los Alamos uses Ariba. Sandia uses its Business Opportunities Website and iSupplier
Registration	SAM.gov registration	Separate supplier onboarding at each lab you target; some opportunities may also require a current SAM.gov record
GAO bid protest	Protests are handled under FAR Part 33, including at GAO	Ordinarily unavailable for subcontract awards, with two narrow exceptions
Labor-law clauses	Applied by the agency	Passed down by the contractor when the applicable clause or contract requires it

Registration is per lab, and each lab runs its own system

Los Alamos National Laboratory uses the SAP Ariba Network. New suppliers request an invitation to register with Los Alamos, then complete the required company, contact, and category information. Registration is necessary before doing business with the laboratory, and suppliers should follow the current LANL Ariba Network Supplier Guide because onboarding fields and account options can change.

Sandia posts opportunities on its Business Opportunities Website and requires registration in its iSupplier portal. Your account must be approved before you can respond to a posting. Sandia also collects socioeconomic classifications and strongly encourages suppliers to keep their SAM.gov registration current.

Plan on separate registrations for each lab you want to sell to. A SAM.gov record alone does not get you into either portal.

Competition windows can be short

As of October 1, 2026, Sandia describes three posting types, and the timelines differ sharply:

• Request for Quote (RFQ): a purchase order is anticipated from capable responses. Small RFQs under $250,000 are typically posted for just 3 business days and designated “Small Business First.”
• Sources Sought: used for opportunities typically above $250,000, posted up to 15 calendar days or more, with an initial 8-day small business set-aside period.
• Request for Information (RFI): exploratory, with no limit on days posted.

If you only respond when a posting appears, a 3-day RFQ can close before you have a quote ready. Build a reusable quote template and a current capability statement before you register, so a short window does not decide the outcome for you.

Sandia also evaluates “clear and convincing information” showing relevant experience, the ability to perform the statement of work, and satisfaction of each mandatory requirement. A response that misses one mandatory requirement is not saved by strong experience elsewhere.

Long-term vehicles sit above one-off buys

Labs also buy through multi-year agreements for needs that recur across the site. Sandia’s corporate agreements, for example, serve goods and services needed across the laboratories. Its Just in Time agreements use a 3-year base period with two 1-year options. Some agreements are firm fixed price, and others are time and materials or commercial service type. Suppliers can also provide value-added services such as order entry, technical consultation, property tagging, warranty support, and on-site maintenance.

If your work repeats across departments, a corporate agreement is a different target than a single RFQ, and it needs a different pitch: coverage, reliability, and service wrap, rather than one-time price. That same distinction matters when considering whether a blanket agreement helps or hurts.

Mistake and fix: treating a GAO protest as your safety net

On agency awards, sellers who lose can file a GAO bid protest under FAR Part 33. On lab subcontracts, that option is mostly missing. GAO ordinarily lacks jurisdiction over protests of subcontract awards. It takes jurisdiction in two narrow cases: when the federal agency that awarded the prime contract asks it to in writing, or when the subcontract was awarded “by” the government, meaning the agency handled substantially all the substantive parts of the procurement.

In a February 2018 decision, GAO B-415676, GAO dismissed a protest of a subcontract awarded by a national laboratory’s operating contractor because DOE made no written request and the contractor controlled the evaluation and award.

The fix is to do your due diligence before you bid. Ask the lab’s subcontracts office what debrief process it offers after an award, and make your decision to respond on that basis, not on a protest right you may not have.

Regional preferences can change the price comparison

As of October 1, 2026, NNSA’s Los Alamos Regional Purchasing Program covers seven Northern New Mexico counties and eight regional Pueblos. It directs the contractor to apply a 5 percent adjustment factor to qualified suppliers that do not meet the definition of a Northern New Mexico small business. The program defines that business as licensed and physically located in the region, with at least 51 percent of direct productive labor hours performed by regional residents. The preference passes down to major subcontractors of $5 million or more.

Contract terms change when the M&O contract changes, so read the current contract language before you price against this.

A short checklist before your first lab response

1. Confirm your SAM.gov registration is current if the opportunity or lab requires it, and note your Unique Entity ID.
2. Choose the lab. Each has its own portal and its own approval step.
3. Register: request a Los Alamos invitation through Ariba or register in Sandia’s iSupplier portal. For Sandia, wait for account approval before you try to respond.
4. Prepare the information the current onboarding process requests, along with a current capability statement.
5. Write a reusable quote template now, sized for a 3-business-day RFQ window.
6. When a posting arrives, list its mandatory requirements first and confirm you meet every one before you spend time on the rest.
