Suzanne,

I think we will need some more info on the "shipping and storage" processes you use.
This will influence the "shelf life" more then the product itself.

Other questions are:
1. How long do you want to store them?
2. Are they being "repackaged"?
3. What are the shop environmental conditions when they reach the floor?
4. Do the flux and soldering methods match the product build process, materials, and design?

and so on just for starters.
