Question Hello Michael, Have a nice Day
My question is:
Can we give Retesting date to Raw Material beyond its expiry date and for how long? Is there any reference in either case.
Answer The only GMP providing guidance on this, worldwide, is the Canadian GMPs.
They state that if the retest date is exceeded, then full specification testing must be performed, and the material is shown to meet specification. The raw material need to be used within 30 days of this testing.
