Field guide

When SIN 517410 fits

Scope fit
A close-looking SIN can still be wrong if the subcategory, PSC, NAICS, or deliverable story points elsewhere.
Signal
517410 Includes but not limited to products and services, such as: leased commercially available satellite bandwidth; shared or private satellite subscription/managed services; satellite phone services; satellite terminals, phones, modems, and related equipment and services. Solutions include transponded capacity consisting of dedicated bandwidth on a commercial satellite in any frequency band. Transponded Capacity includes all services necessary to allow the customer to use the transponded capacity, including: engineering (e.g., development of link budgets, transmission plans); basic customer training (e.g., acquiring satellite signal, peak and polarization); core management and control of the transponded capacity; and required approvals. Subscription Services include but are not limited to: worldwide satellite-based Internet, voice, data, and video services. Subscription services entail existing commercial satellite services solutions, including terminals, in any frequency band. Subscription services include the network management, monitoring, engineering, integration, and operations required to deliver the services. These solutions may include fixed and/or mobile satellite services, along with service-enabling components such as terminals, teleports, and terrestrial interfaces. Host Nation Agreements (HNAs) are separately priced when required. ^^^^NOTE: Subject to Cooperative Purchasing

The official record maps this SIN to NAICS 517410 and PSC DG11. Those codes are not the whole strategy, but they help explain how the offering is categorized for buyers and reviewers.

Part 2

How to prepare the offer story

For service-oriented SINs, keep the service description, labor categories, pricing support, and past-performance examples aligned. A reviewer should be able to see what work is being sold, who performs it, and why the rate story is defensible.

If the SIN is being added through eMod, write down what changes operationally: new scope, new pricing, new files, catalog impact, and who owns maintenance after approval.

Part 3

Buyer and SEO language to keep straight

Use the SIN number, title, category, and subcategory together: SIN 517410 - Commercial Satellite Communications Solutions (COMSATCOM) - Information Technology - Telecommunications. That combination helps a buyer understand the lane quickly and helps the page avoid becoming a vague keyword page.

When writing capability language, explain the actual deliverables and evidence. Do not make the SIN carry the whole message by itself.

Examples

What this looks like in practice

Real-world checkHow to test SIN 517410 before building files

Start with the official title and description: Commercial Satellite Communications Solutions (COMSATCOM) sits under Information Technology > Telecommunications. Then compare your actual commercial offering to that scope, not only to the NAICS code.

If the fit still looks strong, build the proof stack: offering description, pricing support, past performance or product support, and any SIN-specific files the current GSA instructions require.

  • Confirm scope language.
  • Check NAICS and PSC signals.
  • Match the pricing file to the offering type.
  • Keep the support package reviewer-friendly.

Frequently asked questions

Is SIN 517410 part of TDR?

The Refresh 32 workbook marks TDR as Y for this SIN. GSA states that TDR became mandatory across MAS SINs with Refresh 31, so contractors should still verify current contract reporting instructions in official GSA sources.

Can order-level materials be used with SIN 517410?

The workbook marks OLM as Y. OLM treatment should always be verified against the current MAS solicitation, mass modifications, and contract-specific instructions.

Should I pick a SIN only because the NAICS matches?

No. NAICS helps, but SIN selection should be based on the actual offering, official SIN description, category/subcategory, pricing files, and buyer acquisition path.
