I think "price" is an imprecise term that could refer to the pre-tax/tariff amount or the post-tax/tariff amount. It would include shipping, if there is no other way to get the device (as is the case here).
But regardless, they're not saying they would increase the "price" (whatever that means), but just that if the tariff situation changes, then the customer will need to pay the additional tariff. This is the same as what would happen if a state increased the sales tax rate and they had to collect and remit additional sales tax. It just so happens that it's unlikely any state is going to sharply increase its sales tax in the next year, but there's a decent chance the tariff rate will jump. If the sales tax went up, I wouldn't consider that to be the company raising the price. Same for tariffs, in my book.
