Some market analysts expressed initial concerns that the duty rebate program would contribute to increased U.S. imports of Canadian agricultural products, particularly live hogs and processed pork products, since Canada’s pig industry was a major user of imported U.S. corn.8 U.S. trade officials voiced an additional concern. They suggested that the duty-drawback program could result in U.S. trade action against Canada based on how such a duty-rebate program was implemented. For example, suppose that imported U.S. corn was fed to swine that were then slaughtered and processed into various meat cuts such as pork chops. Then, suppose that the Canadian meat packer exported the pork chops to the United States and claimed a certain share (say 30%) of the value of that porkchop as imported U.S. corn meritorious of a duty-drawback. If the true corn value-share of the pork chop were only 10%, than a duty-drawback based on a 30% corn share would represent an export subsidy, which is illegal under WTO rules.
