1. Purpose

This Standard Operating Procedure (SOP) outlines the systematic process for developing sampling plans tailored to different types of raw materials. The purpose is to ensure representative sampling that complies with Good Manufacturing Practices (GMP) and regulatory requirements for quality control.

2. Scope

This SOP applies to all raw materials received at the facility, including Active Pharmaceutical Ingredients (APIs), excipients, solvents, packaging materials, and materials requiring special handling such as hazardous or temperature-sensitive substances.

3. Responsibilities

  • Warehouse Personnel: Provide necessary information about raw material characteristics and ensure correct labeling and segregation.
  • Quality Control (QC) Personnel: Develop, implement, and review sampling plans based on material types and regulatory requirements.
  • Quality Assurance (QA): Approve sampling plans, ensure compliance with regulatory standards, and monitor deviations.

4. Accountability

The QC Manager is responsible for developing and validating the sampling plans, while the QA Manager ensures that sampling plans meet regulatory and quality

standards.

5. Procedure

5.1 General Guidelines for Sampling Plan Development

  1. Regulatory Requirements:
    • Sampling plans must comply with:
      • ICH Q7 – Good Manufacturing Practices for Active Pharmaceutical Ingredients
      • WHO GMP Guidelines
      • ISPE Guidelines on Material Sampling
  2. Factors Affecting Sampling Plans:
    • Type of raw material (API, excipient, solvent, etc.)
    • Batch size and number of containers
    • Supplier history and material criticality
    • Storage conditions and material sensitivity (e.g., temperature, moisture)
    • Regulatory classification (e.g., hazardous, sterile, or controlled substances)

5.2 Sampling Plan Structure

  1. Sampling Plan Components:
    • Material Description: Identify material type and critical attributes.
    • Batch Size: Total weight/volume of the batch and number of containers.
    • Sampling Method: Random, stratified, or systematic sampling.
    • Sample Size: Determine based on batch size and material criticality.
    • Tools and Equipment: Specify tools (e.g., sampling thieves, pipettes) and cleanliness requirements.
    • Documentation Requirements: Detail how to record sampling data.

5.3 Sampling Plan for Different Raw Material Types

5.3.1 Active Pharmaceutical Ingredients (APIs)

  1. Sampling Method:
    • Stratified random sampling to ensure homogeneity.
    • Sample from top, middle, and bottom layers of containers.
  2. Sample Size:
    • Minimum 10% of containers, not less than 2 containers, per regulatory guidelines.
  3. Special Considerations:
    • For sterile APIs, use aseptic sampling techniques in a cleanroom environment.

5.3.2 Excipients

  1. Sampling Method:
    • Random sampling for non-critical excipients.
    • Stratified sampling for functional excipients (e.g., disintegrants, binders).
  2. Sample Size:
    • 5% of containers, with a minimum of 1 sample per batch.

5.3.3 Solvents and Liquids

  1. Sampling Method:
    • Use sampling taps or draw samples from different levels (top, middle, bottom).
    • Ensure containers are grounded to prevent static discharge for flammable solvents.
  2. Sample Size:
    • One sample per container for small batches; at least three containers for larger batches.

5.3.4 Hazardous and Temperature-Sensitive Materials

  1. Sampling Method:
    • Follow specific safety protocols, including PPE and fume hood use.
    • For temperature-sensitive materials, maintain required storage conditions during sampling.
  2. Sample Size:
    • Sample size should be minimized to reduce exposure risk but sufficient for accurate testing.

5.4 Documentation and Record-Keeping

  1. Sampling Plan Approval:
    • Sampling plans must be documented and approved by QA before implementation.
  2. Sampling Records:
    • Document all sampling activities in the Sampling Record Log (Annexure-1).
    • Include date, material name, batch number, sampling method, sample size, and personnel involved.

5.5 Handling Deviations in Sampling Plans

  1. Deviation Reporting:
    • Report deviations such as incorrect sample size or missed containers to the QA Manager.
    • Document deviations in the Sampling Deviation Report (Annexure-2).
  2. Corrective Actions:
    • Identify the root cause of deviations and implement corrective measures.
    • Document corrective actions in the Corrective Action Log (Annexure-3).

5.6 Training and Compliance

  1. Personnel Training:
    • All personnel involved in sampling must be trained in the proper application of sampling plans.
    • Document training in the Training Log (Annexure-4).
  2. Compliance Monitoring:
    • QA must conduct periodic audits to ensure compliance with sampling procedures.
    • Document audit findings in the Compliance Audit Log (Annexure-5).
