may vary significantly between countries. This is illustrated for maize in Tables 1.3
through 1.5 for the United States, Argentina, and South Africa, respectively. Only the
U.S. standard contains a factor for test weight; only South Africa includes a category of
pink maize.
It is noteworthy that the grade standard for maize does not contain a factorfor moisture
content in either of the three countries. However, in the trade the maximum average
moisture content of a lot usually is specified.
