NOTIFICATION 
 
1. Notifying Member:  UNITED STATES 
If applicable, name of local government involved:    
2. Agency responsible:  US Environmental Protection Agency 
3. Products covered (provide tariff item numbe r(s) as specified in national schedules 
deposited with the WTO;  ICS numbers should be provided in addition, where applicable):  Corn, field, forage 
4. Regions or countries likely to be affected, to the extent relevant or practicable: 
[X] All trading partners   
[ ] Specific regions or countries:    
5. Title of the notified document:  Glyphosate; Pesticide Tolerance  Language(s):  English  
Number of pages:  4 
 http://www.gpo.gov/fdsys/pkg/FR-2011-05-11/html/2011-11205.htm  
6. Description of content:  This regulation increases the established tolerance for residues of 
glyphosate in or on corn, field, forage from 6 ppm to 13 ppm. 
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)   
[ ] 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:  Codex has established an MRL fo r residues of glyphosate in or 
on maize at 5 ppm.  The MRL for maize would cover residues of glyphosate on corn 
(maize) forage.  This MRL is different than  the tolerance being established for glyphosate 
on field corn forage in the United States due  to differences in Codex and US residue G/SPS/N/USA/2224 
Page 2  
 
  definitions.  The US tolerance of 13 ppm for co rn, field, forage is necessarily higher than 
the Codex MRL to account for residues of both glyphosate and its metabolite N-acetyl 
glyphosate.  N-acetyl glyphosate is found in genetically modified (GMO) glyphosate-resistant commodities, including corn, grown in th e United States.  Therefore, it is included 
in the US tolerance but not the Codex e xpression, accounting for the difference in the 
established MRLs.
