Import duty from UK

I'm looking for a 20 moa scope rail for the FX Dream Tac and Bagnall & kirkwood have exactly what I need for $113.
I've read all I can find online and am more confused that when I started.
What will the tariff be on this kind of sale????
Is the $800 de minimus still in effect?
It's actually determined by the country of mfg not the country shipping. And the threshold of $800 including shipping being duty free seems to still be gone.
 
I think what you're looking at is £113.62 or $153. I just ordered from Eagle Vision in the UK. they are shipping via Fed Ex and so far, I haven't been notified of any additional fee (brokerage or tariff). I ordered 7 day express for $25 so I'm scheduled to have this Friday. I've read on another thread that UPS adds a brokerage fee for shipments from Europe to US. This isn't what you're looking for but I thought it might be of interest:
