All Level 1 items which do not qualify for SMIC X1, X2, or X4 assignment are assigned SMIC X6. Since the outer packaging of material received from the Navy Supply System may not be marked with an X6 SMIC, end users should consult applicable logistics information (e.g., the Q COSAL, FEDLOG, Haystack, etc.) to determine the current SMIC assignment. If an X6 SMIC is currently assigned in any of the applicable logistics information, the material is considered pre-certified Level 1 material and does not require a Ready-For-Issue tag.
