Am-Mex Products helps companies set up maquiladora operations in the McAllen, Texas, and Reynosa, Mexico, border region. The maquiladora program allows US firms and other foreign companies to import raw materials into Mexico duty-free for assembly there by lower-wage Mexican workers. The program also offers faster startup, lower shipping costs, and central distribution. Its services include contract manufacturing, engineering factory management, warehousing and distribution, cross-border trucking, training, and other services required for international trade. Am-Mex has been in business since 1990 and has around 1 million sq. ft. of manufacturing and warehouse space in Mexico, in addition to its US operation.
