All parts of this standard are compulsive.
This standard replaces and abolishes the following standards: GB 14935-1994 "Tolerance Limit of Lead in Foods", GB 15201-1994 "Tolerance Limit of Cadmium in Foods", GB 2762-1994 "Hygienic Standard for Tolerances of Mercury in Foods", GB 4810-1994 "Tolerance Limit of Arsenic in Foods", GB 14961-1994 "Tolerance Limit of Chromium in Foods", GB 15202-2003 "Maximum Levels of Aluminium in Flour Made Foods", GB 13105-1991 "Tolerance Limit of Selenium in Foods", GB 4809-1984 "Permitted Level of Fluorine in Foods", GB 7104-1994 "Maximum Permissible Level of Benza (Alpha) Pyrene in Roasted and Smoked Meat", GB 9677-1998 "Tolerance Limit of N-nitrosoamines in Foods"， GB 9674-1988 "Tolerance Limit of Polychlorobiphenyls (PCBs) in Marine Foods", GB 15198-1994 "Tolerance Limit of Nitrite in Foods", and GB 13107-1991 "Tolerance Limit of Rare Earths in Plant-foods"
Main differences between this standard and the former individual limit standard are as follows:
-The text format of the standard is modified according to GB/T 1.1-2000;
-Thirteen items of contaminant limit standards such as GB 14935-1994 and GB 15201-1994 are merged into this standard;
-Corresponding modifications are made on partial food varieties and maximum-level index according to the risk assessment and referring to CAC standard;
-Individual item target object is changed, e.g. the maximum-level index taking PCB1 and PCB5 as the target object for polychlorinated biphenyl in GB 9674-1988 is represented with the sum of PCB28, PCB52, PCB101, PCB118, PCB138, PCB153 and PCB180 in this standard, furthermore, PCB138 and PCB153 are added.
-This standard is equivalent to CAC standard, partial food varieties involved in the total arsenic in GB 4810-1994 are abolished, and the maximum-level index of sugars, edible fats, fruit juice and pulps as well as cocoa products are added.
This standard is implemented from October 1, 2005 and the transitional period will last for 1 year. Namely, products produced before October 1, 2005 and meeting the requirements in relevant standards are permitted to be sold until November 30, 2006.
