可能表达不够严谨,应该是ICHQ7a指南问答里,明确说明起始物料不要求按GMP管理
10.Q. If GMP does not start until the starting material is used in the manufacture of APIs, why then are starting material manufacturers inspected for GMPs?
Starting material manufacturers are not routinely inspected by the FDA.
11. Q. Are there any guidance requirements within Q7A for starting materials?
Section 1.3 defines API starting materials and states "This GMP guidance does not apply to steps prior to the introduction of the defined API starting material."
