For the most part, the products of chemistry and plastics are rules-of-origin compliant. In the early days, the most favoured nation rate was zero. Some companies didn't do the paperwork, and they were caught, but anybody that is producing a compliant product has done the paperwork and the goods are moving freely.
What is in play is demand weakness. You've heard about the automotive industry and the construction industry, and these are the industries that the products of chemistry and plastics are sold into, so the impacts are secondary. You could talk about broader global effects around the Iran conflict and supply chain disruption. North America is actually very uniquely well positioned because we have the feedstock and we have domestic production to meet domestic demand.
I made a comment in my remarks around rail transportation and port transportation. Our Achilles heel in Canada is that we continually allow our transportation system to be impacted by labour disruption. That's not just a labour problem; that's a government, industry and labour conversation that needs to be had. We need to find a way to make sure that system is resilient and can meet the requirements of the existing U.S.-Canada trade objective. If we are going to double our non-U.S. exports by $300 billion, we need to solve our transportation problem now.
