I understand your perspective but I want to ask a question, not to you, but for you to think about it. What motivation causes the imports?
If corn syrup is a replacement for whatever they are doing, why are they importing raw sugar? If raw sugar is cheaper than you would expect them to already use sugar for everything and not corn syrup, and switching to corn syrup would be an increase in cost . If raw sugar costs the same, import is additional paperwork, why import? Raw sugar is more expensive, why would they pay more?
Raw sugar can’t be replaced easily in their use case? Now that makes sense.
Which is why I am almost certain that there is a reason why they import raw sugar
