Mexico is proposing to adopt a draft standard for food contact glass and ceramics. This draft standard would expand the scope from ceramics to glass. It is proposed to enter into force 60 days after publication in the official journal

On 18 December, 2015, the World Trade Organization (WTO) circulated a notification (document number 15-6712) [1] from Mexico proposing to adopt the draft Official Mexican Standard NOM-231-SSA1-2015 for food contact glass and ceramics. This new standard would replace the existing standard NOM-231-SSA1-2002 on food contact ceramics. It also expands the scope of products to include food contact glass and establishes limits for the migration of lead and cadmium in these products.

This draft standard is consistent with the following international standards:

  • ISO 6486-2:1981 ‘Ceramicware, glass-ceramicware and glass dinnerware in contact with food release of lead and cadmium – Part 2:Permissible limits
  • ISO 7086-1:2000 ‘Glass hollowware in contact with food – Release of lead and cadmium – Part 1:Test Method
  • ISO 7086-2:2000 ‘Glass hollowware in contact with food – Release of lead and cadmium – Part 2:Permissible Limits

According to the notification, the final date for comments is 15 February, 2016. The draft standard is proposed to enter into force 60 days after its publication in the Official Gazette.

Highlights of this proposed standard are summarized in Tables 1 (pottery, ceramics and porcelain) and 2 (glass).
