# What is IMMEX?

IMMEX is Mexico's export manufacturing programme. The Secretaría de Economía publishes a directory of the companies that hold a programme, with its number, type and status. Testigo attaches an IMMEX entry to a Mexican plant when the company name matches exactly. A plant working under another company's programme will show no entry.
