From the current answers, the most recent of which seems to be a correct solution to the puzzle, it appears not.
Tags have descriptions (you can read them by hovering over a tag in a tag list, or by clicking a tag and reading the description at the top of the page; the descriptions are also shown below each tag in the popup box that appears when you're adding or editing a question's tags). These are often helpful in understanding what we mean by a particular tag name. "Grid deduction" is not just "figuring out" (deduction) the meaning of a block of things arranged in a "grid"-like pattern; it is used specifically for a type of puzzle solved by logically applying a set of constraints to elements of a grid. Sudoku is an example most people are familiar with.
Your puzzle isn't solved in this manner. I think the tags you applied are the correct ones.
(cipher is debatable; I'd probably not include it.)
