On December 1, 2016, the Bureau of Industry and Security (BIS) published in the Federal Register a final rule [160519443–6999–02] that aligns the time limit of License Exception Temporary Imports, Exports, Reexports, and Transfers (in-country) (TMP), which authorizes, among other things, certain temporary exports to Mexico, with the time limit of Mexico’s Decree for the Promotion of Manufacturing, Maquiladora and Export Services (IMMEX) program. Currently, TMP allows for the temporary export and reexport of various items subject to the Export Administration Regulations (EAR), as long as the items are returned no later than one year after export, reexport, or transfer if not consumed or destroyed during the period of authorized use. Other than a four-year period for certain personal protective equipment, the one-year limit extends to all items shipped under license exception TMP. However, the one-year period does not align with the time constraints of Mexico’s IMMEX program, which allows imports of items for manufacturing operations on a time limit that may exceed 18 months. This rule amends TMP to complement the timeline of the IMMEX program. Under this amendment, items temporarily exported or reexported under license exception TMP and imported under the provisions of the IMMEX program would be authorized to remain in Mexico for up to four years from the date of export or reexport. The rule is effective January 3, 2017.
