Retesting of  Primary Packing Material (PPM)

Retesting of  Primary Packing Material (PPM)


  • To lay down the procedure for retesting of primary packaging material (PPM).


  •  This SOP is applicable for retesting of primary packaging material in Quality control


  •  Chemist or above of QC Department for retesting of PPM.
  •  Officer or above of Warehouse Department for giving request for retesting of PPM.


  • Head – Quality Control.
  • Head – Warehouse
  • Head QA- Overall compliance of SOP.



  • Approved primary packaging materials due for retesting shall be tested to determine their suitability for use (e.g after for long periods or other condition that might adversely affect the materials).
  • The criteria of first retesting period shall be considered from initial approved date and thereafter based upon previous retest approval date.
  • Retesting can also be carried out as per any directive from Quality assurance department on need basis or risk analysis.
  •  Refer to Annexure II for the retest period schedule for materials under retest.
  •  The list of retest materials shall be shared by warehouse department in advance and shall provide the reanalysis request form for each material as per SOP .
  •  On receipt enter the detail of reanalysis request form in the “Retest Packaging Material Control Register” (Annexure-1) and allot the A.R No. and worksheet.
  •  A.R.No. shall be allotted by adding suffix ‘/ Rn’ to present AR No. where ‘/’ is separator, R is for retesting and n is the number of times retesting is performed.
  •  The QC personnel shall plan and perform the sampling of material under retest as per SOP  and ensure that quarantine label on each container is affixed.
  •  The QC personnel shall ensure that all existing labels (Including quarantine, sampled and approval) on the each container with ‘X ’(CROSS) mark and affix sampled label.
  •  Perform analysis as per the respective packaging material specification and general test procedure or if it is not mentioned complete testing shall be performed as per the respective specification and STP/GTP .
  • The testing and approval or rejection of retest material shall be as per SOP.
  • After complete testing make the released/rejected entry as per annexure No.A01.
  • Affix labels on container in such manner that the word “Quarantine Labels” is completely overlapped.
