Hi Matt,

We've done a lot of the groundwork already, in identifying each and every product we sell in terms of its tariff code. In theory that should let us predict the duties that SHOULD be charged, and it's the only way to go since tariffs can vary from small to large depending on the particular trade war and protectionist priorities being fought out by People Who Matter at the time. (Oh damn, I didn't want to get dragged into this sort of stuff...) In practice, as you and I know, things are seldom that logical in practice. So we might have to swallow an element of swings and roundabouts at first. But we have pretty robust back-end systems which mean the actual prices we were paying could be automatically fed back in to identify where we were over or undercharging, at least on average, so the system would become more or less self-regulating in time. That's the theory. (And yes, we have the option to pay our shippers, rather than the customer.)
