Dumping is a technical trade term that basically means exporting at prices below the cost of production.
Industry groups from the three nations have written to their trade and agriculture ministers and officials expressing concern over the impact of “Canada’s trade delinquency” on dairy protein markets, the Dairy Companies Association of New Zealand said Thursday.
“Of concern is the purposeful design of Canada’s milk pricing mechanisms to under-price the surplus milk protein generated by its domestic supply management system and incentivize disposal onto world markets,” the New Zealand association said in a statement.
“Collective and coordinated action is requested to address the mechanisms being used by Canada to enable these exports to be dumped on world markets.”
It seems to me they have a strong case.
