I would keep it a PRP.
Do inspections on the trailer that is delivering the material to make sure there are no off smells, damage that could let in water/pests, material that could contaminate your product like blood if it was hauling meat, oil, etc.
Do inspections on incoming materials like shrinkwrap damage if it's wrapped, or whatever you need to look for.
Keep records.
If you make it a CCP you can potentially put a lot of product in jeopardy and setting yourself up for failure of your system on one small mistake. It's not nearly as bad if you have a minor violation of a PRP (no immediate recall).
Just my suggestion.
