My company manufactures single serve powdered beverages mixes that are placed into a machine and dispensed. We are currently looking into adding a "best if used by" label to our cartons. We receive powders from various suppliers with the formulations created, which are then agglomerated before being put into our capsules.
Many suppliers recommend 2 year shelf life from date of production. Due to our production needs however, we currently have powder that has been in our facility for 1 year that has not been further processed.
Should our "Best If Used By" label reflect the supplier recommendation? In other words, our finished product using powder that is a year old would have a best by reflecting only 1 year If we put 2 years from when we further process, that would be giving the product 3 years, which we have not done extensive shelf life on to prove it would work.
Any advice is appreciated!
