Good Manufacturing Practice
The quality system governing how a site manufactures — a property of the facility, not of any one batch.
What is a good manufacturing practice?
Good Manufacturing Practice is the body of quality-system requirements governing how a manufacturing site operates: personnel training, premises and equipment, production and process control, documentation, complaint handling, recall capability and record retention. It is a property of the facility and its systems rather than of any individual batch. Different sectors apply different frameworks. Cosmetics manufacturers commonly certify to ISO 22716, the international GMP standard for cosmetics. Therapeutic goods manufacturers in Australia operate under the Therapeutic Goods Administration's requirements. Food manufacturers work to food safety programmes built on HACCP principles. The practical consequence for anyone buying material is that GMP certification tells you the seller runs a controlled operation with traceability and record-keeping, which makes their batch documentation more likely to be complete and reliable. It does not, by itself, say anything about the specific batch you are being offered.
How Surply uses it
Certifications held by the selling business are separate from the documents attached to a lot. Surply publishes the batch documentation; a seller's site certifications are part of who they are, not proof of what any single batch contains.
Also known as: GMP, ISO 22716, GMP certification, cGMP.
