Good Manufacturing Practice (GMP)
Definition
Good Manufacturing Practice (GMP) is a set of principles and management systems designed to ensure that products are consistently manufactured and controlled to quality standards appropriate to their intended use. WHO regards GMP as an important part of quality assurance. Its core purpose is to systematically manage personnel, premises, materials, production processes, quality control and documentation to reduce manufacturing risks that cannot be fully eliminated through final product testing alone.[1]
GMP is not a single, globally uniform standard or certification. Different product categories, countries and regions may implement GMP principles through regulations, international standards or guidance issued by regulatory authorities.
For example, ISO 13485 is widely used as an internationally recognized quality management system standard for medical devices;[2] ISO 22716 is widely used as international GMP guidance for the production, control, storage and shipment of cosmetics.[3] Countries and regions may also issue their own GMP regulations or guidance, such as the U.S. FDA's Cosmetic GMP Guidance.
Why does it matter?
For regulated products such as medical devices and cosmetics, target markets typically impose requirements on manufacturers' quality management systems or GMP practices. International standards such as ISO 13485 and ISO 22716 are therefore frequently used for regulatory compliance, customer audits, tenders and supplier qualification.
A legal requirement to comply with a quality system or GMP requirements does not always mean that holding a particular third-party ISO certificate is legally mandatory. The specific requirements depend on the product category and target market.
Even where local regulations do not prescribe a particular GMP certification, an independent third-party GMP audit or certification can be an effective supplier screening tool. It helps buyers assess whether a manufacturer has established systematic controls for premises hygiene, personnel, production, quality control, documentation and traceability.
