There are both equivalent statements.

I said that an exempt package must only meet (not exceed) one of the

Class 7 Radioactive for transportation.

You said that both concentration and consignment criteria must be 
exceeded to be a Class 7 Radioactive for transportation.

Both statements are correct.
