FN indicates the condition of a product that is brand new from the factory. For it to be FN, the product should not be more than two years old since manufacturing.

NE refers to a piece of new equipment or part that has no operation time and zero working cycles on it. A resold item can also have an NE tag as long as it was never used. The manufacturing date on NE items is not considered to assign this code, and only the operation of the new part is indicated.

NS code is for new parts that were sold from one or more sellers but still have no operation time or cycles. These are parts that might go through the channel of sales from airlines to distributors and are then given the tag of New Surplus.
