DSCSA-aligned drug supply chain verification with Signal Tags and open schema contracts.

Industry problem

Drug counterfeiting and diversion create patient safety risk and operational exposure. Serialization workflows require reliable verification at dispense and saleable returns checkpoints.

How Signal Tags helps

Use base fields for identity and lifecycle, then add regulated attributes through metadata: ndc, lot, expiry, manufacturer, and optional dea_schedule.

Regulatory context

DSCSA (United States)
EU FMD (Europe)

Code example

const pharmaTag = {
  id: 'st_01PHARMA001',

  createdAt: '2026-03-12T10:00:00Z',
  lotId: 'LOT-2026-PHA-17',

    expiry: '2027-01-31',
    manufacturer: 'Pfizer Inc.',
    dea_schedule: 'none',
  },
}

Loop Engine integration

A recalled tag can trigger a quarantine loop and downstream destruction or return workflows in Loop Engine.
