  NOTIFICATION 
The following notification is being circulated in accordance with Article 10.6. 
 
1. Notifying Member:  MEXICO 
If applicable, name of local governme nt involved (Articles 3.2 and 7.2):   
2. Agency responsible:  Comisión Reguladora de Energía  (Energy Regulatory Commission) 
Name and address (including telephon e and fax numbers, email and website 
addresses, if available) of  agency or authority designated to handle comments 
regarding the notification shall be indicated if different from above:  Comisión 
Reguladora de Energía  (Energy Regulatory Commission) 
3. Notified under Article 2.9.2 [  ], 2.10.1 [ X], 5.6.2 [  ], 5.7.1 [  ], other:   
4. Products covered (HS or CCCN where applicable, otherwise national tariff 
heading. ICS numbers may be provided in addition, where applicable):  
Petrochemicals (tariff headings 2701 to 2901.10) 
5. Title, number of pages and lang uage(s) of the notified document:  Acuerdo por el 
que la comisión reguladora de energía expide la norma oficial mexicana de emergencia NOM-EM-006-CRE-2015, especificaciones de calidad de los petroquímicos  (Decision of the 
Energy Regulatory Commission issuing Emerge ncy Mexican Official Standard NOM-EM-006-
CRE-2015: Quality specifications for petrochemicals) (20 pages, in Spanish) 
6. Description of content:  The aim of the notified Emergency Mexican Official Standard is to 
regulate and promote the efficient developmen t of petrochemical transport, storage and 
distribution activities. 
Given that the production, transport, storage, distribution and first-hand sales of petroleum 
and gas products used as basic industrial raw materials (basic petrochemicals, including ethane, propane, butane, pentane, hexane, he ptane, carbon black feedstock, naphtha and 
methane derived from hydrocarbons obtained fr om deposits located in national territory) 
and intended for use as raw materials in petrochemical industrial processes may be carried 
out by individuals, the quality specifications for these products need to be regulated. Furthermore, the industries that use these products need to be certain that the 
petrochemicals they purchase possess the qualitative characteristics required for the 
industrial processes for which they are intended.  
The urgent nature of this Standard reflects the need to prevent a regulatory vacuum, as of 
2016, for persons subject to the obligation und er Articles 78 and 79 of the Hydrocarbons 
Law concerning the quality specifications for petrochemicals and the related testing, sampling and verification methods. 
7. Objective and rationale, including the nature of urgent problems where 
applicable:  This Emergency Mexican Official Standard lays down the quality specifications 
to be met by petrochemicals used by the hydr ocarbons industry and marketed in national 
territory. G/TBT/N/MEX/299
