1. Notifying Member: CHINA 
If applicable, name of local government involved:   
2. Agency responsible: National Health and Family Planning Commission of the People's 
Republic of China 
3. Products covered (provide tariff item  number(s) as specified in national 
schedules deposited with the WTO; IC S numbers should be provided in 
addition, where applicable): Food additive magnesium silicate 
4. Regions or countries likely to be affected , to the extent relevant or practicable: 
[X] All trading partners   
[ ] Specific regions or countries:

http://members.wto.org/crnattachments/2014/sps/CHN/14_3465_00_x.pdf  
6. Description of content: This standard applies to the food additive magnesium silicate 
obtained by precipitation reaction of sodium silicate and soluble magnesium salt. It 
specifies the technical requirements and testing methods for the food additive 
magnesium silicate. 
7. Objective and rationale: [X] food safety, [ ] animal health, [ ] plant protection, 
[ ] protect humans from animal/plant pest or disease, [ ] protect territory from 
other damage from pests.   
8. Is there a relevant international stan dard? If so, identify the standard:  
[X] Codex Alimentarius Commission (e.g.  title or serial number of Codex 
standard or related text) The specification of magnesium silicate was prepared 
at the 74th JECFA (2011). 
[ ] World Organization for Animal Health (OIE) (e.g. Terrestrial or Aquatic 
Animal Health Code, chapter number)    
[ ] International Plant Protection Convention (e.g. ISPM number)    
[ ] None 
Does this proposed regulation conform to the relevant international standard?   
[ ] Yes   [X] No 
If no, describe, whenever possible, how and why it deviates from the 
international standard: The different index of this standard is that the loss on ignition 
should conform to the percentage stated by the vendor.  
The difference between this standard and the international standard is that the 
index of loss on ignition is not a safety index for magnesium silicate, and the 
requirement of loss on ignition in FCC should  also conform to the percentage stated by 
the vendor. G/SPS/N/CHN/673
