Many raw material suppliers do only a fraction of their business with pharmaceutical, personal care products or cosmetics companies. A raw material thus may have multiple uses. Consequently specifications may be set to ensure consistency of the material from lot to lot. However, the specification boundaries set by a particular supplier, although consistent, can be much wider than those acceptable for GMP manufacturing purposes. In addition, raw material suppliers may use their own internal analytical methods, rather than a compendial method, in support of a COA.
