Tantalum caps degrade over time. You should not be seeing "chipped-off & cracks" regardless of the age. This should not be a shelf-life issue, unless you are storing them in an aquarium. Tell us the story. Solderability is a shelf-life issue and

I have a MS level 3 component that has been on the shelf for 7 years. Should it be baked before usage. The HIC card reads ok- and it was stored with desiccant. History of the part is unknown, was purchased from franchised distribution.
