The Mexican Institute for Social Security (IMSS) is the third largest public buyer of goods and services in Mexico and the single largest purchaser of pharmaceutical products and other medical supplies.
Buying effectively and avoiding bid rigging are therefore key to generating savings for IMSS users and Mexican taxpayers and promoting more competition in public procurement.
In 2011, after making significant efforts to improve the effectiveness of its procurement strategy, Mexico decided to step up its fight against bid rigging by signing an agreement with the OECD to work together on implementing tighter public procurement processes.
