I’ve not not long imported a frame myself and responded on the thread above.

I’ve just paid import duty on my Steve Potts in within the last month.
I paid the following on what was marked up as bike parts (Frame, fork, bars, stem, seatpost.)
The price for the ‘parts’ was $4465 US dollars which is around £2878 (This included the postage)
My import duty and VAT was £751.82.
Hope this helps.
On the $4465 US dollars I paid:
£599.03 Import VAT
£134.45 duties
£18.34 Brokerage surcharges
Total £751.82 GBP
