There are a few exceptions that I know of from the TSA, and these have to do with medication or disability assistance equipment; and children's formula baby food, etc. (for the liquid restriction).
All other prohibitions are not subject to exemptions. This is because some of the items are classified as hazardous material (HAZMAT) that need to carried by certified companies/equipment; in other cases it is banned by the FAA for safety; and finally because it can be considered a weapon.
Your only recourse - if the item cannot be checked in, is to have it shipped to your destination as cargo - and if it is hazmat it may not even be allowed to fly and will have to be driven there.
