Overview
Standard Reference: ISO 21976:2018
Title: Packaging - Tamper verification features for medicinal product packaging (ISO)
ISO 21976:2018 specifies requirements and provides guidance for the application, use and check of tamper verification features on packaging of medicinal products. It supports harmonized implementation worldwide to indicate whether outer or immediate packaging has been opened or tampered with - reducing risk from adulteration and entry of falsified medicinal products into the supply chain.
Key topics and requirements
- Purpose and scope
- Defines the role of tamper verification features as indicators of opening or tampering (not a full prevention measure).
- Intended primarily for medicinal product packaging but principles can apply to other sectors.
- General requirements
- Tamper verification features must indicate unauthorized opening or manipulation while not compromising statutory information (including tactile markings).
- Application can affect opening force; design should balance verification with usability and regulatory labeling.
- Categories covered
- The standard details descriptions, criteria and verification guidance for a range of packaging types, including:
- Folding boxes (glued and specially constructed)
- Sealing labels and tapes
- Film wrappers and sleeves
- Breakable or tear-away closures
- Container inner seals or membranes
- Display blister packs and flexible packaging
- Blow–fill–seal (BFS) containers
- New and emerging technologies
- Verification and checking
- Provides guidance on how to check tamper verification features (inspection and verification practices are specified per category).
- Emphasizes objective evidence and conformity with specified criteria.
Practical applications and users
Who uses ISO 21976:2018:
- Pharmaceutical manufacturers and marketing/manufacturing authorization holders designing or approving packaging.
- Packaging designers and converters developing tamper-evident closures, labels, sleeves and seals.
- Quality assurance / regulatory teams ensuring packaging meets tamper-verification requirements and does not obscure mandatory information.
- Contract packagers and supply chain managers implementing and checking tamper features during packaging and distribution.
- Regulators and inspectors evaluating compliance with tamper-verification expectations and related legislation (e.g., Falsified Medicines Directive contexts).
Benefits and uses:
- Improves patient safety by making tampering easier to detect.
- Harmonizes expectations across markets for tamper-evident packaging design and verification.
- Supports procurement and supplier specification for compliant packaging solutions.
