1. Purpose

The purpose of this Standard Operating Procedure (SOP) is to define a systematic approach for cross-verifying dispensed quantities of raw materials in pharmaceutical manufacturing. Proper verification ensures accuracy, minimizes material discrepancies, and maintains compliance with Good Manufacturing Practices (GMP) and regulatory guidelines.

2. Scope

This SOP applies to all personnel involved in the weighing, verification, and approval of dispensed raw materials in the Production, Quality Assurance (QA), Quality Control (QC), and Warehouse departments.

3. Responsibilities

Dispensing Operator: Ensures correct dispensing and prepares materials for verification.
QA Officer: Verifies and approves dispensed quantities.
QC Analyst: Conducts random sampling checks to validate dispensed materials.
Warehouse Supervisor: Ensures accurate material tracking and documentation.
Production Supervisor: Oversees the verification process and ensures adherence to procedures.

4. Accountability

The QA Manager is accountable for ensuring that all cross-verification activities comply with GMP, FDA, ICH, WHO, and company policies.

5. Procedure

5.1 Preparation for Cross-Verification

Ensure the **weighing and dispensing area is clean** and free from contaminants.
Verify that the weighing balance is **calibrated and within its validity period**.
Ensure that dispensed materials are labeled correctly, including:

Material Name
Batch

Number

Weighed Quantity

Weighing Date

Operator Name

Check that the dispensed material is stored in **appropriate containers** to prevent contamination.

5.2 Cross-Verification Process

QA personnel must verify each dispensed material against the **Batch Manufacturing Record (BMR).**
Use an **independent weighing balance** to verify the quantity of each dispensed material.
If a discrepancy is detected:

Reweigh the material to confirm the deviation.
Record the deviation in the **Cross-Verification Log (Annexure-1).**
Notify the Production Supervisor and QA department for corrective action.

If the verification confirms the correct quantity:

QA must sign off on the **Cross-Verification Log (Annexure-1).**
Material is **approved for further processing.**

5.3 Handling Cross-Verification Deviations

If the dispensed quantity **exceeds or falls below** the required limit:

Material must be **reweighed in the presence of QA personnel.**
Document the issue in the **Deviation Report (Annexure-2).**
Corrective action must be implemented before the material is approved.

Rejected materials must be:
- Quarantined and labeled as **”Rejected”.**
- Disposed of according to waste management SOPs.

5.4 Post-Verification Activities

Ensure that approved materials are transferred to the appropriate **production or storage areas.**
Update the **Material Usage Log** to track dispensed and verified quantities.
Submit completed **cross-verification records** to the QA department for review.

5.5 Periodic Review and Audit

QA must conduct **weekly random checks** to ensure compliance with cross-verification protocols.
All records must be **retained for at least five years** for audit purposes.
Deviations must be reviewed in **monthly QA meetings** to identify trends and corrective actions.
