To comply with clause 18.104.22.168 of ISO 22000, do we need to specify composition of raw material, such as resin? Because sometimes supplier don't want to specifically define the composition since it is confidential. They only mention that the additive used in resin is comply to FDA and suitable for used in food contact.
Is it adequate if supplier only mention that their product is comply to FDA, or is there any evidence needed to ensure that the material comply to packaging regulation
Thank you for your help
