Re: Drop Cord
It sounds to me like you are out of luck

Re: Drop Cord
Why does it "have to be" SO cord through that air space?
Could you possibly run a conduit(or similar) from the concrete ceiling to a box mounted to the grid and secured back up to the deck?
Could you possibly create a 2x2 opening in the ceiling, frame and sheetrock, and then run out of the deck box?
If that air space is the problem - eliminate it.

(3) Where run through doorways, windows, or similar openings
(4) Where attached to building surfaces
Exception to (4): Flexible cord and cable shall be permitted to be attached to building surfaces in accordance with the provisions of 368.56(B)
(5) Where concealed by walls, floors, or ceilings or located above suspended or dropped ceilings

Re: Drop Cord
400.7 addresses ALLOWED uses.
I generally frown of using cords, but sometimes it is needed: ie, the lifts at your local auto shop; slicing and mixing machines at a cheese manufacturer(400.7(A)(8) ~ 2002).
Yes, these are places I worked in - either ends of the spectrum ~ auto shop=general filth/cheese production=general cleaniness.
EDIT:
I guess the OP will have to give us some more info on what's on the end of the cord

Re: Drop Cord
There is no way you are going to get around 400.8(A)(2).

Re: Drop Cord
My thoughts exactly. The thing on the end will not matter.

Re: Drop Cord
how about running conduit down to the ceiling and installing a jbox on the bottom of the ceiling and starting the cord there. pull wire down to the jbox. then the cord is not passing through the ceiling, nor is it in the air space above the ceiling.

Re: Drop Cord
If damage to the drop ceiling is a concern, you could cut a 2' x 4' 5/8" plywood to fit into the tile opening, screw it to the t-bar real well, support the wood with rod if necessary, and then screw your j-box to the underside of the wood. Now a hard tug on the cord won't bring down the drop ceiling.
