Just received an order from FC-Moto, my first since they switched to UPS from DHL as the international shipper. Got whacked with extra duty that is around 18-20% on a pair of TCX shoes, some Held CE Level 2 armour, and an IXS jacket. Ended up as a ~$200 bill when combined with HST and various 'fees' on top of a ~$600 order for a near 33% surcharge. Of course, they give almost no details on the costing, so it's difficult to identify why it was so much.
Went back and compared to a very similar order from late 2022 when DHL was the shipper (2 x TCX shoes and IXS gloves in that case), and total import costs were around $70 on a $450 order, or about a 16% surcharge, roughly half of UPS.
As far as I'm aware, no new duties/tariffs have been applied to Euro products (they definitely have to US, apparently 25% on any US-made motorcycle gear), so the only difference is the shipper. I should say, I've had a lifetime of being disappointed by UPS, and consider them the worst of a bad lot in the shipping world by a fair margin. FedEx tries hard to be as crap, but can't quite hit the same dizzying heights of utter contempt for their customers.
I've been a steady customer of FC-Moto for ages, buying most of my gear from them. Unfortunately, if they stick with UPS, the value proposition isn't quite what it was...
