No there will not be any duty or sales taxes.
Those were covered by GSP when you paid their import fees.
FWIW, just to confuse you, you did not pay duty/sales tax.
The GSP did, on your behalf.
This is a difference without a distinction until you have to return something to the seller. In that case, getting your entire payment back can be fussy and difficult.
Fortunately it is also very very rare.
