SOP: Use of CMO Batch and Item Number Systems

This SOP: Use of CMO Batch and Item Number Systems describes how your company manages, verifies, and cross-references the batch and item numbers assigned by Contract Manufacturing Organizations (CMOs) with your own Final Product Item Numbers. It ensures full GMP-compliant traceability across outsourced manufacturing, testing, warehousing, and distribution activities.
 
This SOP is professionally written and pre-filled (~95% complete), requiring only company-specific details before approval.
Designed for organisations working with external CMOs, the template defines QA’s oversight responsibilities, Supply Chain’s documentation requirements, and CMOs’ obligations to provide accurate manufacturing and testing identifiers. It also includes guidance for maintaining a traceability register and managing discrepancies.
 
Includes:
• Rules for linking CMO batch numbers to internal product item numbers
• Responsibilities for QA, Supply Chain, and CMOs
• Requirements for documentation (CoA, CoM, packing lists)
• Traceability register structure (Appendix)
• Guidance for handling numbering inconsistencies
 
Why it matters:
Clear numbering control is essential in outsourced pharmaceutical models. This SOP ensures your organisation maintains regulatory-grade traceability and prevents errors in batch release, labelling, and documentation.
