Law and regulation
Binding requirements are identified by jurisdiction and cited to the controlling text when publicly available. We do not present a guidance document or industry practice as if it were a regulation.
Evidence policy
Editorial Standards & Corrections
YB Inspection publishes technical content for pharmaceutical visual-inspection teams. Our goal is to make each claim traceable, label the authority of each source correctly, and separate general information from site-specific decisions.

Our editorial commitment
Source status is part of the answer
A technically accurate sentence can still mislead if the source is described incorrectly. We distinguish binding requirements, compendial standards, final or draft guidance, industry consensus, scientific literature, and site-defined choices. Where a numerical value or acceptance criterion is not universal, we say so.
Compendial standards
USP, Ph. Eur., JP, and other pharmacopeial material is described with its chapter or monograph status and applicable scope. Informational chapters are not described as universally mandatory requirements.
Regulatory guidance
Final and draft guidance are labelled separately. Draft guidance is described as nonbinding agency thinking and not as an implemented rule or automatic authorization.
Industry consensus and practice
PDA, ISPE, ECA, BioPhorum, and peer-reviewed literature may support technical interpretation, but they are identified as industry or scientific sources rather than law.
How technical pages are prepared
- Define the product, process, jurisdiction, and decision that the page actually addresses.
- Prefer primary regulatory, pharmacopeial, government, standards-body, and peer-reviewed sources.
- Link regulated, scientific, and numerical claims to the supporting source where licensing and public access permit.
- State limitations and identify decisions that still require an approved site procedure, protocol, risk assessment, or regulatory strategy.
- Change the displayed update date only when the page receives a substantive revision.
Decision boundary
YB articles and downloadable tools are educational frameworks. They do not establish a product-specific validation conclusion, batch disposition, acceptance criterion, legal interpretation, or regulatory strategy. Each organization remains responsible for approving its own procedures, protocols, risk assessments, and market-specific requirements.
