SOP for Handling of Retest Material | SOP for Retesting of Raw Materials |
- Retesting of Raw Material SOP covers below points :
- Frequency for Retest date of raw materials
- Handling of Retest Material
- Retest Material register / log format
1.0 OBJECTIVE :
- To provide a standard procedure for Retesting of all Approved Raw Materials.
2.0 SCOPE :
- This procedure is applicable for scheduling, sampling and retesting of all raw materials.
3.0 RESPONSIBILITY :
- Warehouse officer : To schedule and intimate Quality Control Department and storage/shifting at designated place.
- Quality Control Chemist and above: To sample, retest and conclude
4.0 ACCOUNTABILITY:
- Quality Control Head
5.0 PROCEDURE :
All raw material used in products bear a date (Retest date), after which the material will not be used without further testing.
5.1 Frequency for retesting of Raw Materials is as follows,
| Sr. No. | Material | Retesting Frequency |
| 1 | Active Materials (Except: Vitamins, Enzymes and Antibiotics) | One year from initial analysis |
| 2 | Excipients, except colours, flavours | Two year from initial analysis |
| 3 | Flavours, Vitamins, Enzymes and Antibiotics | Six months from initial analysis |
| 4 | Colour | One year from initial analysis |
| 5 | Empty hard Gelatin capsule shells | One year from initial analysis |
5.2 Retest date shall be mentioned on “Approved Label” when the material is approved.
5.3 Get identified raw materials for retesting by warehouse department.
5.4 Prepare a list of such Raw materials in last week of every month for retest date of next month and share the information to Quality Control Department.
5.5 Deface/ tear the Approved label and affix Quarantine label on the container of retest material.
5.6 Shift raw material for retesting from “Approved Material Area” to “Quarantine Area” (change the status of material).
5.7 Do not perform Retest of material, if cost of analysis is more than approximate cost of balance stock of material.
5.8 Dispose the material as per Disposal of Laboratory Waste – SOP
5.9 Prepare Retest intimation.
5.10 Receive intimation from Warehouse department.
5.11 On receipt of intimation, enter the details in Retest Raw Material register.
5.12 Assign the Analytical Report number in Retest Raw material Register.
5.13 Carry out sampling of Raw Materials as per Sampling of Raw material -SOP
5.14 Allocate the sample to analyst for the analysis based on priority.
5.15 Sampling quantity of retest material shall be decided based on the tests to be carried out for retesting of material and it shall be mentioned in respective specification
5.16 Analyze Raw material as per Pharmacopoeia or In-house specification.
5.17 Critical tests which are specified for retesting in respective specification shall be carried out for retesting.
5.18 If material meets the specification then material is approved.
5.19 Write the analytical result after analysis in worksheet and submit to competent technical staff for approval of report.
5.20 Approve the raw material in ERP system as per regular approval procedure.
5.21 No sample shall be preserved as ‘Control Sample’.
5.22 Affix the Approved label (on green coloured paper) manually with new Re-testing date on the Bags/ Container (Annexure No.:02).
5.23 If the retest material is not complied with specification, reject the raw material in ERP system as per regular approval procedure.
5.24 Affix the Rejected label (on red coloured paper) on the Bags / Container (Annexure No.: 03).
5.25 Retest due date should not be more than expiry date.
5.26 In case if expiry date falls before retest date then the same expiry date shall be considered for further retesting date of the material.
5.27 Only three retesting’s are allowed, beyond this treat the material as Rejected.
