The preliminary draft seeks to harmonize and update the legal framework with NOM-004-SSA1-2013, which specifies that the use of lead compounds should be avoided as an ingredient or raw material in the manufacture of various products, among which are included : paints, enamels, coatings and inks, furniture, paintings, emulsions and enamels for exteriors and interiors of residential real estate, offices, schools, hospitals and nurseries. Considering the worldwide trend towards the elimination of lead content in paints, inks, varnishes, lacquers and enamels, NOM-003-SSA1-2006 needs to be modified.
