"Trump did threaten to raise the tariff even more to 25%, where it might start to have a larger impact on PET."
Potentially yes but only on sales to the US, not China or rest of world and currently sales to the US are close to insignificant.

Sales to China which is what this investment is all about for me. I think that the current market valuation doesn't even reflect the likely stellar growth in earnings from China alone over the next few years. For me, the potential future USA sales are insignificant compared to China (and rest of world can be added to China) so any impact on exports to USA are no concern to me simply because I'm not yet factoring in any sales to the USA. I guess others are factoring US sales so for them there will be some potential impact although it must be small relative to China sales.
