Tamper proof seals on sensitive parts of the product itself? I'm thinking about this from an NSA iterdiction/implant point of view. You can't trust the shipping companies, so you have to either physically secure it (and your question says not secured) or have indicators that show tampering. The physical equiv of hash/checksum checking.
