And again, you missed the point completely, that the foreign vendor in this case knew exactly what I will be charged with, no crystal ball required, they just chose to hide it from me.
ScubaGaskets definitely knew
that you would be paying for an import tariff and
may have even known how much it was going to be on the day you ordered your stuff. However, it's a BIG ask for them to incorporate that into their point-of-sale software.
Condsider that they probably ship to over 100 countries, with more couriers than just DHL. Any country on any day and any courier on any day can change their tariffs/fees. So, the time required to keep up with that number of combinations is just not compatible with a low-overhead operation like ScubaGaskets. Their prices are low, in large part,
because they avoid overhead by not having distribution networks, international warehouses, and import/export expert staff.
Yes, it sucks that we in the US have lost our free perk of being able to buy internationally and not deal with the costs/paperwork associated with that, but it IS the new normal per current administration policty. I'm sure you're not seeing it from all vendors because some have chosen to eat the costs in the name of keeping US customers happy. Others have ways around it of they're big enough. ScubaGaskets has chosen the low-cost way of dealing with it (for them) - probably so they can keep costs lower for their
global customer base.
This should not have been a surprise to anyone. It was all over the news for a solid month and a half before it happened and was even discussed here in a couple threads. It sucks for those of us who were used to getting a free ride on duty. I'm sorry you got shafted with an unexpected bill. That sucks.
Question, though: With the added tariff/processing cost, were the kits you bought more, less, or the same as buying them from a brick and mortar dealer here in the US, or having your local shop do the work?
