1. Purpose

To establish a standard procedure for the qualification and re-evaluation of vendors supplying raw materials, excipients, solvents, packaging components, and other critical inputs used in API manufacturing, ensuring compliance with GMP and regulatory requirements.

2. Scope

This SOP applies to all vendors supplying materials used in the manufacturing of Active Pharmaceutical Ingredients (APIs) including starting materials, reagents, intermediates, solvents, and

primary/secondary packaging materials.

3. Responsibilities

  • Purchase Department: Identifies potential vendors and coordinates initial documentation.
  • QA Department: Conducts technical review, audits, qualification, and maintains vendor approval status.
  • QC Department: Evaluates incoming material quality and provides analytical feedback.
  • Warehouse: Ensures material segregation and usage based on vendor status.

4. Accountability

The Head of Quality Assurance is accountable for vendor approval decisions and ensuring vendors continuously meet GMP standards and product quality requirements.

5. Procedure

5.1 Vendor Categorization

  1. Vendors shall be categorized based on the type of material supplied:
    • Category A: API starting materials, solvents, reagents
    • Category B: Packaging materials (labels, containers)
    • Category C: Other service providers (e.g., testing labs, logistics)

5.2 Vendor Qualification Process

  1. Qualification steps:
    • Request vendor for Vendor Questionnaire (Annexure-1)
    • Obtain technical dossier including:
      • GMP certificate
      • Manufacturing license
      • ISO/DMF/CEP certifications (if applicable)
      • Material specifications and CoA formats
    • Perform site audit for Category A vendors using Vendor Audit Checklist (Annexure-2)
    • Evaluate documentation and assign qualification status:
      • Approved
      • Conditionally Approved
      • Not Approved
  2. Document all findings in the Vendor Qualification Report (Annexure-3).

5.3 Evaluation Criteria

  1. Qualification decision is based on:
    • Material quality performance (initial 3 lots)
    • Compliance to specifications and regulatory documentation
    • Audit observations (if applicable)
    • History of complaints or deviations

5.4 Vendor Re-Evaluation

  1. Re-evaluation to be conducted:
    • Annually for critical material suppliers
    • Biennially for packaging and non-critical vendors
    • Immediately in case of quality failures or regulatory alerts
  2. Parameters for re-evaluation:
    • Lot rejection rates
    • Complaint history
    • Changes in ownership or manufacturing process
    • Updated regulatory documentation
  3. Record re-evaluation details in Vendor Re-Evaluation Form (Annexure-4)

5.5 Vendor Status Management

  1. Maintain Approved Vendor List (Annexure-5) with:
    • Vendor Name
    • Material Supplied
    • Approval Date
    • Status (Approved, Conditional, Blacklisted)
  2. Ensure that ERP/SAP system reflects current vendor status to prevent unapproved material usage.

5.6 Disqualification of Vendors

  1. Vendor may be disqualified due to:
    • Repeated quality failures
    • Audit non-compliance
    • Regulatory warning letters
    • Non-fulfillment of contractual obligations
  2. Disqualification must be documented and justified in Vendor Disqualification Form (Annexure-6).
