# What is PROSEC?

PROSEC is a second programme register of Mexico's Secretaría de Economía, published next to the IMMEX directory with the same layout. Each programme names the company, its sector codes and the plants where the goods are made. Testigo attaches a PROSEC entry to a plant by exact company name, as it does for IMMEX.
