This document discusses the rules for charging components into pharmaceutical manufacturing batches according to CFR 211.101. It states that production procedures must ensure drug products have the labeled identity, strength, quality and purity. Components must be weighed, measured or subdivided as specified. Any container a component is removed to must be labeled with identification information. Weighing operations require adequate supervision and a second check of released components, weights and container labels. Automated equipment may only require one person if it meets certain requirements.
