Incomplete bill-of-materials and chain-of-custody data
Furniture is a composite product, and the single most common failure mode is a passport that captures the finished SKU but cannot trace the timber, panels, foam, and metal frame back to verifiable supplier evidence. A passport that lists 'wood' without an FSC or PEFC chain-of-custody reference, or 'particleboard' without a formaldehyde class, will fail a conformity assessment and can trigger market-surveillance action, withdrawal orders, and Member-State fines. Because much furniture is imported, the importer carries this liability even for upstream data it did not create. The platform treats each material stream as a versioned, audit-logged component node with provenance metadata, and flags any node missing a mandatory attribute before the passport can be published.
Component-level bill-of-materials model, supplier-declaration ingestion with mandatory-field validation, FSC/PEFC and formaldehyde-class capture, and a pre-publish completeness gate.
