Mexico Adopts Maximum Mercury and Cadmium Limits in Batteries, New Standards for Tyres

Mexico has established maximum mercury and cadmium limits in batteries and battery packs, including cylindrical, prismatic and button cell batteries. These limits are 0.0005 percent mercury and 0.0020 percent cadmium by weight of the battery unit, although in the case of button cell batteries a more flexible allowance of two percent by weight of mercury is being provided.

NOM-212-SCFI-2017 also requires batteries to include certain specific information, including the product designation; year and month or week of manufacture; positive terminal polarity; nominal voltage; and name or brand of the producer or supplier. If the body of the battery is too small to include all of the required information in a legible manner, that information may be jointly included in the body of the battery or its packaging. Additionally, the packaging must include a graphical representation or the name of the product, except in instances where that information is obvious; the name and address of the importer or domestic producer; the country of origin; and an indication of quantity in accordance with standard NOM-030-SCFI-2006, except in instances where the quantity can be ascertained by the consumer at first glance. Batteries that are not pre-packaged for consumer sale are exempt from these labelling requirements.

NOM-212-SCFI-2017 also sets forth test methods as well as conformity assessment and sampling procedures. These requirements will enter into force on 28 September 2019.

Separately, Mexico has adopted a new mandatory standard (NOM-086-SCFI-2018) for new radial tyres for use in motor vehicles weighing 4,536 kilogrammes (10,000 pounds) or less, as well as new radial tires for use in motor vehicles weighing more than 4,536 kg with a T, H, V, W, Y or Z speed rating. Slated to enter into force on 1 December, the standard includes definitions, technical specifications, sampling and testing requirements, marking provisions and conformity assessment requirements.
