Mexico's Ministry of Economy has implemented two revised standards for the labelling of textile and apparel products, which must now comply with appropriate mandatory or voluntary standards.

The standards were adopted a part of mandatory regulations in Mexico and will enter into force on 9 September.

Generally, all apparel, apparel accessories, textile products and home textiles with over 50% textile content must comply with the official Mexican standard for mandatory labelling requirements.

In order to allow manufacturers, importers and marketers to adjust their production processes to comply with the new requirements, Mexican authorities will accept products that are legally in the country before the effective date.

An SGS press release stated that the items may continue to be sold until as long as they meet the previous standard, NMX-A-099-INNTEX-2007, and comply with the rest of the parameters specified in NOM-004-SCFI-2006.

According to the Official Gazette, NMX-A-2076-INNTEX-2013 'Textiles - Chemical fibers – Generic names' supersedes NMX-A-099-INNTEX-2007, and lists the generic names used to designate the different types of chemical fibres currently manufactured on an industrial scale for textile use.

The major change in this new standard is that the generic names must be written without capital letters.

Additionally, NMX-A-6938-INNTEX-2013 'Textiles – Natural fibers – Generic names and Definitions' supersedes NMX-A-099-INNTEX-2007, and provides generic names and definitions for the most important natural fibres in accordance with the fibre constitution or specific origin.

The standard provides a list of names in common, together with the relevant standard designations. One important change in this standard is that the words "lana" (wool), and/or "pelo" (hair), can be now added before the generic name of some animal fibres.

The Mexican Bureau of Standards (DGN), however, has said it is seeking clarification on whether natural fibres on clothing labels, under the new rules, may be listed in all capital letters, all lowercase letters, or with the first letter capitalised and the rest in lowercase.

The American Apparel and Footwear Association (AAFA) added that DGN has not issued a clarification for synthetic fibres either, and said it will continue to work with the US and Mexican Governments to seek clarity on this issue.

The new standards also required that, for apparel and apparel accessories, one or more permanent and legible labels must be attached at the collar, waist or any other visible location with labelling information in Spanish, or in any other language in addition to Spanish.

This labelling information must include commercial brand name, fibre composition, size, care instructions, country of origin, and name and address of the manufacturer/ importer with a voluntary mention of the federal taxpayers register number.
