Similar type of products here. Our shelf life is between 12-15mo and ingredients shelf life is on average 18-24mo.
Is it a new company or have you been manufacturing for a while? I would start with a safe time limit, like around 12mo, if this makes sense according to your raw materials average age when you pack it.
I would then send samples for monthly analysis when they hit this mark of 12 months old and keep monitoring the stability until you hit a shelf life time that is suitable for your company.
You will probably have a case of 'Best Before' and not 'Expire' date.
I'm not sure if BRCGS has any specific requirements for how you determine it though....
