NAICS 541690 other scientific and technical consulting obligations

A residual code with $14.3 billion behind it

Census NAICS titles that begin with “other” are catch-alls. Code 541690 holds scientific and technical consulting that is not environmental consulting, not logistics consulting, not computer-systems design, and not another more specific professional-services code the officer selected. That residual status makes the $14,333,153,771.96 total harder to narrate as a single product. It is the sum of tagged contracts, not a named scientific program.

Eight thousand one hundred eighteen awards is a thicker book than many manufacturing codes at similar dollar levels. The mean of about $1.8 million per award sits between small advisory orders and large technical-support vehicles. The packet does not identify disciplines — chemistry, nuclear, agricultural, or otherwise — inside the residual class. Award descriptions on the industry page are the only packet-adjacent place to see those details.

Because 541690 is a leftover bin, two similar technical-support contracts can land here or in a neighboring code depending on how the officer reads the principal purpose. Comparisons across years or across agencies can move when coding practice changes even if the underlying work does not.

Residual professional-services codes collect work that did not fit a tighter box. That makes 541690 a poor label for a single scientific discipline and a fair label for a $14,333,153,771.96 contract book. Readers who need environmental, logistics, or CPA work should use those specific hubs rather than assuming the leftover bin contains them.

What the obligation total does and does not measure

The $14.3 billion is a legal-commitment sum on USAspending contract awards tagged 541690. It is not laboratory throughput, not a publication count, and not cash already disbursed. Outlays on professional-services contracts often follow invoices for labor. Open vehicles can carry obligated balances that have not yet been billed.

The 8,118-award count is not a count of scientists. One award can cover a team; many awards can go to the same firm. SpendingVault does not collapse recipients in this packet. Use the 541690 industry page for recipient-level rows.

How 541690 differs from nearby consulting codes

Environmental consulting (541620), logistics consulting (541614), and other management consulting (541618) are separate six-digit codes with their own hubs. Dollars on those pages are not inside this $14,333,153,771.96. A reader totaling “all federal scientific consulting” would need several NAICS pages plus any untagged assistance — a sum this packet does not compute.

Research-and-development codes and laboratory manufacturing codes are also separate. A technical consulting award is not the same tag as an R&D contract even when the subject matter overlaps.

Research-and-development NAICS codes, when present on other industry pages, measure R&D contracts, not this consulting tag. A technical consulting award can discuss research without being tagged as R&D. The $14.3 billion follows the 541690 tag, not the subject matter in a statement of work.

Using the industry table

Read 8,118 awards and $14.3 billion as the two coordinates for this residual class. Rank 541690 on the all-industries index to see its dollar order among professional-services codes. Then open the other scientific and technical consulting industry page for the award list.

Do not treat the residual title as a reason to ignore the number. Residual codes can be large. This one is $14,333,153,771.96 in tagged contract obligations.

Coding caveats

Catch-all NAICS codes absorb work that did not fit a tighter box. They also absorb miscoded work. SpendingVault does not recode USAspending. The published total is whatever officers tagged 541690.

Assistance awards without NAICS remain outside the figure. Updates to the USAspending extract will move both the dollar sum and the 8,118-award count.

Using a catch-all without over-reading it

Open the other scientific and technical consulting industry page and read descriptions before concluding what “scientific” meant on a given award. The NAICS title is a Census class, not a peer-reviewed field. Eight thousand one hundred eighteen awards will not share one specialty.

Rank 541690 on the all-industries index next to other 541 codes. The dollar order is real. The product identity is not. USAspending.gov is the source; SpendingVault does not recode leftover tags into tighter classes.

Questions

What does NAICS 541690 include in USAspending?

It includes contract awards tagged Other Scientific and Technical Consulting Services. The SpendingVault aggregate is $14,333,153,771.96 in obligations on 8,118 awards. The code is a residual consulting class, not a named scientific program. More specific consulting NAICS codes and untagged assistance are outside this total.

How many awards are under NAICS 541690?

USAspending contract records indexed here show 8,118 awards. That count is not a headcount of consultants. Dividing $14,333,153,771.96 by 8,118 yields about $1.8 million per award. Individual award amounts are on the industry page. The packet does not publish a median.

Is this the same as environmental consulting?

No. Environmental consulting is NAICS 541620, a different six-digit code with its own industry page. Logistics consulting and other management consulting are also separate. NAICS 541690 is the residual scientific and technical consulting tag. Do not add those pages together without checking for overlapping awards.

Are research grants in the $14.3 billion?

Not by default. This total is built from USAspending contract awards that carry NAICS 541690. Assistance awards, including many research grants, often have no NAICS and therefore do not enter the industry aggregate. Program pages are the better surface for assistance listings.
