P406 is the GHS precautionary statement “Store in a corrosion resistant/...container with a resistant inner liner”. UN GHS Annex 3 assigns it to Corrosive to metals (chapter 2.16), Category 1. The English wording is the same as UN GHS Rev.11 in EU CLP and Canada. The wording differs in US OSHA. Canada’s official French text is “Stocker dans un récipient résistant à la corrosion/… avec doublure intérieure” and Mexico’s Spanish text is “Almacenar en un recipiente resistente a la corrosión/en un recipiente... con revestimiento interior resistente”. In the UN GHS Rev.11 label matrix it is used with 1 hazard statement (UN only).
