GMP stands for Good Manufacturing Practice: the system of rules that makes sure medicines are consistently produced and controlled to the quality their registration requires. cGMP stands for current Good Manufacturing Practice, the term used by the US FDA. The "c" is a reminder that manufacturers are expected to use systems and technology that are up to date today, not simply whatever was acceptable when the rules were written. In practice, GMP and cGMP describe the same idea; what really differs between markets is whose GMP a site follows and who has inspected it.
What GMP actually covers
GMP is not a single test or certificate. It is a way of running a factory so that quality is built in rather than checked at the end. Every GMP code covers broadly the same ground: a quality management system with a quality unit independent of production; trained, qualified staff; premises and equipment designed, cleaned and maintained to avoid mix-ups and contamination; validated processes, cleaning and test methods; controlled raw materials and suppliers; documentation and records that let every batch be traced; independent quality control testing and batch release; and systems for deviations, complaints, recalls and change control.
Why the "c" in cGMP
The FDA's regulations for finished medicines, in 21 CFR Parts 210 and 211, are titled current good manufacturing practice. The word "current" allows the agency to expect practices to move with the times. Equipment, data-integrity controls and testing methods that were acceptable twenty years ago may not meet the standard today, even though the regulation's wording has hardly changed. Other regulators achieve the same effect by revising their guides more often, which is why "cGMP" is mainly a US regulatory term, even though suppliers worldwide use it in their marketing.
The main GMP codes buyers meet
| Code | Who uses it | Notes |
|---|---|---|
| US cGMP (21 CFR 210/211) | US FDA | Finished products; APIs are inspected against ICH Q7 |
| EU GMP (EudraLex Volume 4) | EU and EEA regulators | Part I for medicines, Part II for APIs (ICH Q7), plus annexes such as Annex 1 for sterile products |
| PIC/S GMP Guide | The 50-plus regulators in the Pharmaceutical Inspection Co-operation Scheme | Closely aligned with EU GMP; membership signals a mature inspectorate |
| WHO GMP | Many regulators in Africa, Asia, Latin America and the Middle East, and WHO prequalification | The basis of the WHO-GMP certificates widely used in export trade |
| Revised Schedule M | India (CDSCO and state regulators) | Revised in 2023 to bring Indian GMP close to WHO and PIC/S standards |
| ICH Q7 | Worldwide, for APIs | The common GMP standard for active ingredients |
What matters more than the label
A supplier that says "we are cGMP compliant" or "we follow GMP" has told you very little. The useful questions are about evidence.
Who inspected the site, and when? A recent inspection by the US FDA, an EU authority, a PIC/S member or WHO prequalification carries more weight than a self-declaration. Ask for the inspection reports or certificates, and check them with the authority that issued them.
Does the approval match your market? A WHO-GMP site may be perfectly acceptable for many importing countries and still not be eligible to supply the EU or US. Our article on which certifications actually matter goes through this market by market.
What is the inspection history? Warning letters, import alerts or non-compliance reports are public for US and EU inspections, and a site's history tells you far more than its brochure. Our guide to how Indian CDMOs comply with US FDA, EU GMP and WHO GMP explains how these systems work in practice.
Where GMP shows up in day-to-day buying
GMP is not only something an inspector checks once every few years. It shapes the everyday relationship between a buyer and a manufacturer.
It appears first in the quality agreement, which sets out who releases batches, who investigates complaints, how deviations and out-of-specification results are handled and how quickly the buyer must be told. It appears in change control: under GMP, a manufacturer cannot quietly change a raw-material supplier, a piece of equipment or a test method that affects a registered product, and a good partner will notify you before it does. And it appears in data integrity. Regulators expect records to be attributable, legible, contemporaneous, original and accurate, often summarised as ALCOA, and many recent warning letters concern records rather than equipment.
If you audit a supplier, or ask a consultant to do so for you, these are the places to look: the deviation and complaint logs, the change-control records for your product, and how laboratory data is recorded and reviewed. They tell you far more about a site's real GMP culture than a tour of a freshly painted production hall.

Frequently Asked Questions(FAQs)
What is the difference between GMP and cGMP?
GMP (Good Manufacturing Practice) is the general term. cGMP (current Good Manufacturing Practice) is the US FDA's term, stressing that manufacturers must use up-to-date systems and technology. The principles are the same.
What is the full form of cGMP?
cGMP stands for current Good Manufacturing Practice, the standard set out for finished medicines in the US regulations 21 CFR Parts 210 and 211.
Is WHO GMP the same as EU GMP or US cGMP?
They share the same principles, but they are separate codes enforced by different inspectorates. A WHO-GMP site is not automatically eligible to supply the EU or US, which require their own inspections or recognised equivalents.
What is Schedule M?
Schedule M is India's GMP standard under the Drugs and Cosmetics Rules. It was revised in 2023 to align Indian GMP more closely with WHO and PIC/S standards.
Which GMP applies to APIs?
ICH Q7 is the common GMP standard for active pharmaceutical ingredients. It is adopted as Part II of EU GMP and used by the US FDA and many other regulators.
