published on August 3, 2006 and was not notified to the World Trade Organization. Note othat the
standard specifies an impurities content of no more than 1.0 percent(≦1.0%) for soybeans for feedstuff. The
standard has not been applied to soybean imports since its implementation.
National Standard of the People’s Republic of China
Soybean for feedstuffs
Issued on August 3 2006
Implemented on November 1 2006
Issued by General Administration of Quality Supervision, Inspection and Quarantine of People’s
Republic of China and National Association of Standardization Administration of China
This Standard is formulated on the basis of NY/T 135-1989 Soybean for Feedstuffs.
The main technical differences between this Standard and NY/T 135-1989 Soybean for Feedstuffs
are as follows:
--Indicators of unsound kernel, moldy kernel and heat damage kernel are added;
--Indicator of permitted urease activities is deleted;
--Indicators of crude fiber and crude ash are deleted.
NY/T 135-1989 Soybean for Feedstuffs shall be replaced from the implementation date of this
This Standard was proposed by the Ministry of Agriculture of People’s Republic of China.
This Standard is under the jurisdiction of National Feedstuff Standardization Technical
This Standard was drafted by National Feedstuff Supervision and Inspection Center (Wuhan),
Harbin Pufan Feedstuff Limited Company, Shandong Liuhe Group.
The main drafters of this Standard were Yang Haipeng, Lu Deqiu, Lv Mingbin, Guo Jiyuan, Yang
Lin, Liu Xiaomin.
This Standard was first promulgated in 1989 as National Standard GB 10384-1989 before
adjusted as Agricultural Industrial Standard in 1997.
