> Any harvestable trees are first logged and sold worldwide, mostly to pulp paper plants in the US and Canada.

I work in the paper industry in the US and there is little to no reason to import fiber for pulp. The company I work for actually exports pulp. 100% of our fiber comes from the US. I'd wager that the paper industry in Brazil receives the majority of the locally harvested fiber if we are making baseless claims. At least my unsubstantiated claim makes economic sense.

Edit: Brazil is one of the top 10 paper producing countries. https://www.iea.org/news/iea-deepens-cooperation-with-brazil-with-new-benchmarking-report-on-the-pulp-and-paper-sector
