- What to confirm: Confirm target application, compatibility requirements, customization needs, quantity, and sample expectations before quoting DSCSA Phase 3 — Wholesaler Compliance for 2026.

## FAQ
- Q: Does DSCSA require RFID or just barcode?
  A: DSCSA requires a 2D barcode (DataMatrix) on saleable units. RFID is not mandatory but is widely deployed by wholesalers for throughput at receiving and outbound. Most large wholesalers run RFID + barcode hybrid; small wholesalers may rely on barcode alone but at slower throughput.
- Q: What's the deadline for full DSCSA Phase 3 compliance?
  A: The November 27, 2023 statutory date was extended by FDA's 1-year stabilization period. Enforcement ramp is now active through 2024-2026. By late 2026 the FDA expects all trading partners to be operating fully interoperably.
- Q: How big is the typical DSCSA compliance investment?
  A: Mid-sized wholesalers (1-3 DCs, $500M-2B revenue) typically invest $2-8M over 18-24 months for full Phase 3 compliance — covering serialization-aware WMS upgrade, RFID portal hardware, EPCIS integration and process redesign. Larger wholesalers spend $20-50M+.
- Q: What happens at saleable returns if I cannot verify in 24 hours?
  A: Per DSCSA, unverified returns cannot be re-introduced into saleable inventory. Most wholesalers quarantine and re-attempt verification or destroy. Loss rate runs 0.5-3% of returned inventory pre-RFID; sub-0.5% post-RFID with API integration via the Verification Router Service (VRS) maintained by GS1 US and HDA.
- Q: How do EPCIS 1.2 and EPCIS 2.0 differ, and which version should we standardise on?
  A: EPCIS 1.2 (the FDA guidance baseline cited by HDA and major distributors) supports XML; EPCIS 2.0 adds JSON serialisation, sensor data extension and improved error handling. Both are valid for DSCSA, but trading-partner inertia favours 1.2 today; most large wholesalers run dual-stack and let counterparties choose. IntuitionLabs explicitly notes FDA guidance identifies GS1 EPCIS 1.2 as the minimum standard version to support, so 1.2 is the floor rather than the ceiling.
- Q: What is the relationship between DSCSA and EU FMD for multi-region operators?
  A: DSCSA is a transactional traceability model (electronic exchange of TI/TS/TH between trading partners) while EU FMD is a point-of-dispense verification model (pharmacist scans against a national hub before dispensing). Both demand 2D DataMatrix carriers with GS1 element strings (GTIN + serial + lot + expiry); the differences live in aggregation (mandatory in practice for US, voluntary in EU), tamper evidence (mandatory in EU, not specified in US) and records governance.
