With India I haven't seen such glaring examples of them being used as a way to frustrate trade as I have in other cases. I think there's just a lack of clarity and a need to make sure we have a harmonized approach.
I would use the example of chemical residues. The big concern is that we have trade in pulse crops valued at nearly $1 billion a year going to markets that don't have up-to-date MRL policies, with India being one example that relies on Codex.
If we add oilseeds and cereals, on an annual basis we have $3 billion of trade from Canada going out into a bit of a regulatory void. The issue then becomes that if you do detect a residue of a chemical—which could be one-tenth of what the acceptable level is in Canada—but you are going into a country that doesn't have any stated policy, what guidance do courts or traders use in case of arbitration?
