The estimates are from DF orders. I only order shoes, so the duty rate is 8.5% +$7 disbursement? fee via UPS, don't know for clothing. I had three invoices from the previous week when the 25% off code was active, and they were all 8.5% + $7 fees.
I received my Smets order via DHL and the customs is basically 22% of order total. My order from slam jam via DHL was 23%. I would say be prepared for that rate if shipped via DHL and over $200.
I got the $25 fish and wildlife fee waived from my okini order for a pair of GAT's and it resulted in a 8.5% + $7 disbursement total via UPS as well.
