Short answer
A Full Material Declaration describes materials and substances in a product or component to a defined level of detail. An FMD is not generally an EU legal deliverable, but it can support REACH, RoHS, PFAS, SCIP, and customer requirements when scope, thresholds, and data quality are explicit.
Key takeaways
- FMDs, list-based declarations, and SDSs serve different purposes.
- The declaration needs product, revision, mass, and substance traceability.
- “Full” must be defined through coverage, thresholds, and confidential-substance handling.
- Validate mass balance and format before using data in product assessment.

FMD, list declaration, and SDS
A list-based declaration answers against a defined regulated list. An FMD seeks to describe all or a defined portion of composition. An SDS communicates hazards and safe handling for substances and mixtures and is not normally a full composition declaration for an article. Choose evidence according to the decision it supports.
Standardised formats
The IPC-1752 family provides XML-based formats for material declaration exchange. A format does not ensure quality: product identity, declaration class, substance list, threshold, and supplier approval still require validation.
Quality criteria for a usable FMD
Check part number and revision, total mass, material hierarchy, substance identifiers, concentration or range, unknown share, exemptions, validity date, and signatory. Mass balance should be credible and omissions explicit. A machine-readable file with the wrong identity remains invalid evidence.
Confidentiality without blind spots
Suppliers may protect trade secrets. Define what may be masked, applicable thresholds, and how regulated substances remain disclosed. Options include ranges, third-party review, or restricted access, not an undefined “proprietary” field.
Validate before roll-up
Run schema and field checks, identity matching, mass and concentration checks, and plausibility review against material type. Flag missing parts and conflicting responses. Approved data receives status, reviewer, and validity; uncertain data must not automatically become green compliance.
Ownership and updates
Define when a new declaration is required: material, supplier, or part revision change; a new substance list; or expired validity. Retain the original file and normalised data. The approval flow should distinguish complete, partial, and rejected declarations and preserve the reviewer’s rationale.
How Verca can support the process
Verca can connect declarations to suppliers, materials, components, BOMs, and product versions and expose missing or stale data. The customer owns declaration requirements and acceptance criteria.
Frequently asked questions
Is an FMD an EU legal requirement?
Not as a universal document type. It can efficiently collect data needed for several legal or customer requirements.
Can an SDS replace an FMD?
Usually not. An SDS need not disclose full composition and is not designed as an article or BOM declaration.
Must mass balance equal exactly 100%?
Method and tolerance should be defined. Material unknowns or unexplained deviations must be investigated.
How long is an FMD valid?
There is no universal validity period. Define reassessment triggers and request a new version after relevant change.
