§ Topic · SBOM
Software Bill of Materials, by jurisdiction.
Where a machine-readable SBOM is mandatory, expected or still emerging — and which format satisfies the most regulators with the least rework.
TL;DR
Generate one CycloneDX (or SPDX) SBOM per release. It satisfies FDA today, PMDA today, Health Canada today, and the EU CRA from December 2027 — no per-market rework. Pair it with a VEX file describing known vulnerabilities and per-component support level.

CycloneDX vs SPDX
Both are accepted everywhere SBOM is required. CycloneDX (OWASP) has richer vulnerability integration via VEX and broader medical-device tooling. SPDX (Linux Foundation, ISO/IEC 5962:2021) has stronger licensing metadata and longer regulatory history. If you have no preference, default to CycloneDX 1.5 JSON.
SBOM is not enough
An SBOM lists components. Regulators want to know which components are exploitable in your device. Ship a VEX file (CycloneDX VEX or CSAF 2.0) alongside the SBOM, declaring exploitability status for each known CVE. FDA reviewers explicitly look for this in §524B submissions.
Frequently asked
What format should my SBOM be in?
CycloneDX or SPDX, both in machine-readable form (JSON or XML). The FDA explicitly names both; the EU CRA, PMDA, Health Canada and MFDS accept either. CycloneDX has slightly broader medical-device tooling support; SPDX is the older ISO/IEC 5962:2021 reference.
Do I need a separate SBOM per market?
No. Generate one SBOM per release in CycloneDX or SPDX, then distribute the same file to every regulator. The deltas are in the surrounding documentation (vulnerability summary, support level, update timeline), not in the SBOM itself.
How often must I regenerate the SBOM?
At every release of the device software, plus whenever a third-party component (library, container image, firmware blob) changes. Most teams automate this in CI so the SBOM ships alongside the build artifact.
Does the SBOM need to include known vulnerabilities?
FDA §524B requires a known-vulnerability summary AND the support level for each component. This is typically expressed as a separate VEX document (Vulnerability Exploitability eXchange) referencing the SBOM by hash.
