Win US Government Contracts From Abroad: SAM.gov Guide

The Myth That Keeps Foreign Companies Out of the World’s Largest Buyer

Every year, the United States federal government spends more than 700 billion dollars on goods, services, and construction through public contracts. It is the single largest procurement market on the planet, larger than the next several countries combined. Yet ask a mid-sized exporter in India, the Gulf, or Southeast Asia whether they have ever bid on a US federal contract, and the answer is almost always no. Not because they lack the product or the price. Because they believe, wrongly, that US government contracting is reserved for American companies headquartered inside the country.

That belief is outdated. The US federal government regularly buys from foreign-owned and foreign-located firms, particularly in IT services, scientific equipment, specialized manufacturing, and niche consulting where domestic supply cannot meet demand. The real barrier is not eligibility. It is unfamiliarity with the system that gatekeeps every dollar of federal spending: the System for Award Management, known to insiders simply as SAM.gov.

This guide walks through exactly what a non-US company needs to do, step by step, to register, search, and credibly bid on US government tenders, without needing a Washington lobbyist or a six-figure compliance budget to get started.

Who Can Actually Bid: Clearing Up the Eligibility Question

There is no blanket rule barring foreign entities from US federal contracts. What exists instead is a patchwork of restrictions that apply selectively, depending on the agency, the product category, and national security sensitivity.

Defense-related procurement, anything passing through the Department of Defense or touching controlled technology, carries the heaviest restrictions, including International Traffic in Arms Regulations and Buy American Act provisions that favor domestic content. Civilian agency contracts for IT services, professional consulting, scientific instruments, medical supplies, and general commodities are considerably more open, particularly when the foreign supplier offers something the domestic market cannot match on price, capability, or availability.

The practical takeaway: before assuming you are excluded, check the specific solicitation. Many civilian agency tenders for software development, translation services, market research, engineering design, and specialized hardware are open to foreign-registered entities that complete the standard registration process.

Step One: Get Your Unique Entity ID and Register on SAM.gov

SAM.gov is the master gateway. No registration, no contract, no exception. As of 2026, the registration system has tightened considerably under what the General Services Administration calls the Revolutionary FAR Overhaul, a sweeping update to the Federal Acquisition Regulation that has introduced stricter entity validation and new cybersecurity attestations tied to the Cybersecurity Maturity Model Certification framework.

The first thing any company needs is a Unique Entity ID, a twelve character alphanumeric code that has replaced the old DUNS number entirely. This is generated directly inside SAM.gov during registration, with no need to go through a third party identifier provider.

Registration itself typically takes between two and four weeks for a foreign entity, longer if there are mismatches between your legal business name and your tax identification details. SAM.gov now runs real-time verification checks against government registries, and even small inconsistencies, a comma in “Company, Inc.” versus “Company Inc.”, can trigger a manual review that adds fifteen to thirty business days. Foreign companies should prepare their legal documentation with this level of precision in mind before starting the online form.

One detail that catches many international applicants off guard: SAM.gov now treats P.O. boxes and virtual office addresses as high risk and requires supporting documentation, such as a lease agreement or utility bill, to confirm a genuine physical presence. If your company operates from a registered office with shared facilities, gather this proof in advance.

Step Two: Understand the Notarized Entity Administrator Letter

This single requirement causes more registration failures than any other part of the process. After completing your online SAM.gov application, you must submit a notarized letter naming your Entity Administrator, printed on official company letterhead, signed in the physical or remote presence of a notary. SAM.gov now accepts Remote Online Notarization in jurisdictions where it is legally recognized, which is a meaningful convenience for companies outside the US that cannot easily access an in-person American notary.

Without an approved letter uploaded to the Federal Service Desk within thirty days of your online submission, your registration is deleted and you start over. Build this into your timeline from day one rather than treating it as a final formality.

Step Three: Choose Your NAICS Codes Strategically

The North American Industry Classification System code you select during registration is not a bureaucratic afterthought. It determines which set-aside opportunities you are eligible to see, how the government categorizes your capability, and which size standards apply to you. A foreign company offering enterprise software, for instance, should research whether to register under a code tied to custom software development or one tied to data processing services, since each opens a different set of solicitations.

Spend time on this step. Many companies default to the broadest possible code and miss highly relevant, lower-competition tenders sitting under a more specific classification.

Step Four: Search for Opportunities the Right Way

Once registered, opportunity search happens through SAM.gov itself, which has absorbed several previously separate systems. The old FPDS.gov contract award search has been retired in favor of SAM.gov’s own award data tools, and historical subcontracting reports that once lived on eSRS.gov are now native to the platform as well. This consolidation, while occasionally confusing during the transition, ultimately means one login and one search interface for opportunities, awards, and past performance research.

Foreign bidders should set up saved searches filtered by their NAICS codes and by specific agencies known to procure internationally, such as the State Department, USAID-successor agencies, and parts of the Department of Health and Human Services. A generalized daily scan of “all opportunities” wastes time. A filtered, saved search delivers relevant tenders directly.

A global tender aggregator platform that already monitors thousands of government portals, including SAM.gov, can shortcut this discovery process considerably, surfacing only the opportunities that match your sector and capability rather than requiring you to build and maintain your own filters from scratch.

Step Five: Understand What Happens After You Are Registered

Registration is not a one-time task. SAM.gov registrations expire exactly 365 days after approval and must be renewed annually. An expired registration does more than block new bids, it immediately suspends payment processing on any contracts you currently hold. The recommended practice is to begin renewal sixty to ninety days before expiry, precisely because the verification steps under the new regulatory framework take longer than they used to.

Foreign companies should also expect a new layer of compliance: SAM.gov has proposed standardized attestations that contracting officers will use as part of award eligibility decisions, covering areas like labor compliance and ownership disclosure. These attestations are becoming a routine part of registration maintenance rather than a one-off form, so treat your SAM.gov profile as a living document that needs quarterly review, not something to set up once and forget.

Why Past Performance Documentation Deserves Special Attention

Federal evaluators weigh past performance heavily in technical evaluation, often as heavily as price itself for anything beyond simple commodity purchases, and foreign companies frequently struggle to present past performance in the format US contracting officers expect. A foreign company’s strongest project references may come from contracts with foreign governments, multilateral institutions, or private multinational clients, none of which appear in any US federal past performance database that a contracting officer might otherwise check directly. This makes the narrative past performance section of a proposal disproportionately important for foreign bidders compared to established domestic contractors who can often point a contracting officer toward CPARS, the federal Contractor Performance Assessment Reporting System now migrating into SAM.gov, for independently documented prior federal performance.

A foreign company should build past performance references with the same rigor a domestic contractor would apply to a CPARS-equivalent record, specific, quantified outcomes, verifiable client contacts willing to respond to reference checks, and direct mapping between the cited prior work and the specific requirements of the solicitation at hand. Generic statements about company history or broad capability carry little weight in federal technical evaluation compared to two or three tightly relevant, well-documented prior engagements that closely mirror the scope being solicited.

Common Mistakes Foreign Bidders Make

The most frequent error is treating SAM.gov registration as the finish line rather than the starting point. Registration gets you visibility. It does not get you a contract. The second most common mistake is underestimating documentation timelines, foreign companies routinely lose weeks because they did not anticipate the notarization and verification steps. The third is choosing NAICS codes too broadly, which buries a company’s profile among thousands of competitors instead of surfacing it for the niche opportunities where it would actually be competitive.

A fourth, more strategic mistake: ignoring subcontracting routes. Large prime contractors holding major federal awards are required to submit small business subcontracting plans, creating genuine demand for capable foreign subcontractors in specialized technical areas. This pathway into US federal work is far less competitive than bidding directly as a prime, and it is almost entirely invisible if you only search SAM.gov for posted solicitations rather than studying who has already won the primes.

A Closer Look at the Civilian Agencies Most Open to Foreign Suppliers

Not every civilian agency operates the same way when it comes to foreign supplier participation, and a foreign company will get considerably more traction by understanding which parts of the federal government actively need capabilities that the domestic market either cannot supply at sufficient scale or cannot supply at a competitive price. The State Department and its successor structures for international development programming routinely procure services tied to overseas program implementation, translation, cultural and language expertise, and in-country logistics support, areas where a foreign firm with genuine regional expertise has an inherent advantage over a purely domestic competitor bidding on work it has never actually executed on the ground.

The Department of Health and Human Services and its constituent agencies procure an enormous volume of scientific equipment, specialized laboratory services, and public health program support, some of which draws on global supply chains and international research partnerships in ways that naturally open the door to foreign-registered suppliers with relevant scientific or manufacturing credentials. The General Services Administration, beyond running SAM.gov itself, also manages substantial procurement for IT modernization and professional services that increasingly accept proposals from companies offering globally distributed delivery models, particularly in software development and data services where time zone coverage and specialized technical talent pools abroad are a genuine selling point rather than a liability.

Foreign companies researching this landscape should resist the temptation to assume that because one agency or one specific solicitation excluded foreign participation, the entire federal government works the same way. Restriction policies are set agency by agency, and in many cases contract by contract, which means the right research approach is solicitation-specific rather than a single blanket assumption applied across the whole of SAM.gov.

Understanding the Federal Acquisition Regulation Overhaul’s Practical Impact

The Revolutionary FAR Overhaul rolling out through 2026 is reshaping more than just registration mechanics. It touches the clauses embedded in actual contract terms, the representations and certifications bidders must complete, and increasingly, cybersecurity requirements tied to the Cybersecurity Maturity Model Certification framework that apply with growing breadth beyond traditional defense contracts into civilian agency work as well. A foreign company bidding into this environment should expect contract terms to shift meaningfully during the life of a multi-year award, not just at the point of initial solicitation, and should build that expectation into its commercial planning rather than assuming the terms it bid on will remain static for the full contract period.

This overhaul is also introducing new deviation tracking and faster clause turnover than federal contractors have historically experienced, meaning a company that wins a federal contract needs an internal process for monitoring regulatory updates relevant to its specific contract vehicle, rather than treating compliance as a one-time review completed at the proposal stage. For smaller foreign firms without an in-house federal compliance team, this is precisely the kind of ongoing administrative burden that justifies budgeting for specialized US federal contracting compliance support as a real cost of doing business in this market, not an optional extra.

A Practical Timeline for a First-Time Foreign Bidder

Companies new to this market consistently underestimate how long the runway needs to be before a first bid submission. A realistic timeline starts with legal entity and tax documentation preparation, ensuring perfect consistency between your legal business name and tax identification details, which should begin well before touching the SAM.gov registration form itself. Registration and the notarized Entity Administrator Letter process typically consumes two to four weeks under normal circumstances, longer if any name or address mismatch triggers manual review. NAICS code research and saved search configuration should happen in parallel with registration rather than after, since a company that waits until registration is approved before starting to study relevant solicitations loses valuable lead time on understanding the specific agencies and contract vehicles most relevant to its capability.

Only once registration is fully active and a company has identified several genuinely relevant live or recently closed solicitations should it begin drafting an actual technical and price proposal, ideally after studying at least two or three previously awarded contracts in the same category to understand realistic pricing and the kind of past performance evidence that historically wins in that specific niche. Companies that compress this entire sequence into a few rushed weeks because they spotted a single attractive solicitation almost always submit a weaker proposal than companies that treated market entry as a structured, multi-month process from the outset.

Why This Market Is Worth the Effort

The administrative overhead of US federal registration is real, but so is the prize. A single multi-year IT services contract with a civilian agency can be worth more than an entire year of regional private sector work for a mid-sized firm. The federal government also pays reliably and on documented terms, a meaningful advantage compared to private buyers in many markets.

For companies that have already proven themselves on international tenders through multilateral development banks or regional government contracts, the leap to US federal procurement is a logical next step in building a globally diversified contract pipeline. The system rewards patience and precision far more than it rewards speed, which is exactly why thorough preparation before your first submission matters more here than in almost any other procurement market in the world.
