US FDA
21 CFR 211.63 - Equipment Design, Size and Location
Plain-language explanation, inspection context and common violation patterns.
What it says
Equipment used in the manufacture, processing, packing or holding of a drug product must be of appropriate design, adequate size, and suitably located to facilitate operations for its intended use and for its cleaning and maintenance.
Paraphrased for plain-language clarity. Always verify against the current published regulation text.
What it means in practice
- This is the foundational equipment provision that the entire IQ/OQ/PQ qualification lifecycle exists to demonstrate compliance with, even though the regulation itself never uses those terms.
- Appropriate design is judged against the equipment's actual intended use, not a generic industry standard - equipment suitable for one product or process may not be appropriate for another.
- Maintenance to prevent malfunctions or contamination is an ongoing obligation, not a one-time qualification event completed at installation and never revisited.
What FDA inspectors look for
- Whether equipment location and layout genuinely facilitate cleaning and maintenance, or whether awkward placement creates areas that are difficult to clean or inspect.
- Whether a documented qualification record exists connecting the specific equipment to its intended use and design rationale.
- Whether ongoing maintenance records show equipment is being kept in the condition its qualification assumed, rather than qualification being treated as a one-time event.
Most common violation
Equipment used for a purpose or scale beyond what its original design and qualification actually support, or equipment maintained reactively after failures rather than through a planned preventive maintenance programme.
