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.
OH - Overhauled
OH condition refers to the possible overhauling of the product or equipment. This could involve completely or partially disassembling the product and restoring it to an optimum/maximum level of functionality.
