UPS in the USA is a giant disaster right now! Do NOT use UPS for shipments from outside the USA until they they get their sh*t together. This whole tariff thing has been a disaster of bad planning and even worse implementation on the US side. Nobody knows what the tariff should be, could be outta be , etc.
I have a customer in the USA - the only customer I've sent a package to since the tariff monster show and I warned him beforehand - who ended up with UPS charging him 3 times for the one product, using 3 different customs product code numbers, all of them wrong. One was for products made of aluminium coming from Russia!! This even though the order included a proper invoice with country of origin (Germany) and the correct customs product code number for the merchandise. UPS just ignored all that. It took the customers weeks to even get any paperwork or a receipt from UPS and now he's getting nowhere getting it corrected and a refund for what he overpaid. The guy was charged over $500 duty alone on merchandise worth €230 (including €30 shipping). He should have paid 15% + a UPS fee for processing, maybe $60 tops.
My freight brokers tell me they have nothing but problems and complaints regarding UPS in the USA.
I hear DHL Express is okay; FedEx is hit or miss, but the problem is trying to determine exactly what the buyer will have to pay for US customs duty on any given shipment. Keep in mind that the shipping company - whether UPS, FedEx or DHL Express - handle the customs paperwork for the shipment, NOT US Customs. US Customs only see the shipment if they flag it for inspection or if some dope sniffing dog barks at it.
The situation is so bad it is endangering the entire future of my business. Without access to the US market I will have to close the workshop.
