Is is true still that under $2,500 is duty free?  Or is the De Minimis now $800?  Thinking of getting some AntMiner S9 units now that the price came down, but if the limit is $800, I'll just get two of the September delivery at $310 each, rather than either higher quantity or the more expensive one week delivery ones.

Also, is there a minimum time I would need to wait to order two more?  (assuming keeping it under $800 is a worthwhile goal)  Or I could just do another order the day after, and as long as they ship separately, I'm good?  (or do they accumulate your 30-day, etc., import history, and tax for all of it on the second shipment in 30 or x number days?)

This seemed like the best thread with previous respondents to ask this in.  Will also probably ship to PA, as the one person mentioned.  If I will have to pay 28% + 6% no matter what, I might reconsider.
