When product compliance data lives in spreadsheets, supplier emails, PDF certificates and regulator portals, every audit turns into a scramble and every regulatory change creates risk that surfaces too late. Fragmented records slow customer responses, bury penalty exposure, and inflate the operational cost of staying compliant across markets. The durable fix is not tidier folders. It is to centralize compliance data into one source of truth linked to the bill of materials, so substance, supplier and certificate data is captured once and reused across obligations. This analysis maps where compliance data actually originates, why manual consolidation breaks down at enterprise scale, and how global manufacturers build a centralized compliance data backbone that stays audit-ready as regulations shift. It covers BOM-level compliance tracking, automated supplier data collection, AI document parsing, and multi-tier supply chain visibility, and shows how a single dataset can serve REACH
