Frequently asked questions

Which SBOM format does the FDA prefer?

Short answer: It depends on the device classification, intended use, and connectivity profile — but the controlling references are FDA's February 2026 premarket guidance, AAMI SW96, and IEC 81001-5-1. The sections above walk through how each applies. For the full context, work through the relevant section above and the linked services below — every answer here is grounded in current FDA guidance and the standards your reviewer is using.

Can I use CycloneDX for SaMD 510(k) submissions?

Short answer: It depends on the device classification, intended use, and connectivity profile — but the controlling references are FDA's February 2026 premarket guidance, AAMI SW96, and IEC 81001-5-1. The sections above walk through how each applies. For the full context, work through the relevant section above and the linked services below — every answer here is grounded in current FDA guidance and the standards your reviewer is using.

Is SPDX an ISO standard?

Short answer: It depends on the device classification, intended use, and connectivity profile — but the controlling references are FDA's February 2026 premarket guidance, AAMI SW96, and IEC 81001-5-1. The sections above walk through how each applies.

What is the difference between CycloneDX and SPDX for VEX?

Short answer: CycloneDX vs SPDX medical devices is a discrete deliverable inside the Secure Product Development Framework (SPDF). FDA expects it documented, traceable, and version-controlled inside your QMS. For the full context, work through the relevant section above and the linked services below — every answer here is grounded in current FDA guidance and the standards your reviewer is using.

How do I convert SPDX to CycloneDX for medical software?

Short answer: Treat it as a process, not a one-off document: own the requirement in design controls, map it to a current standard, generate evidence during V&V, and surface the residual risk in your postmarket plan. For the full context, work through the relevant section above and the linked services below — every answer here is grounded in current FDA guidance and the standards your reviewer is using.

What are the NTIA minimum elements for medical device SBOMs?
