I agree that its not their fault these tariffs are in place, I also agree they have the right to pass this cost along to consumers. It is certainly their responsibility to inform themselves and consumers of the additional cost if they want to do good business. My problem is their lack of knowledge and communication of this if they are offering international shipping. Every manufacture I work with sends out emails and communications on changes of pricing due to duties, tarriffs, cost of materials, etc... these are not new things in business that just started happening in 2025.
In my business when we make a mistake due to our lack of knowledge/experience and it costs me money, I do not pass that along to my customer. I take it as loss and a lesson learned in business and make adjustments to assure less mistakes are made in the future. If one loss is going to cripple your business you are not running a good business. Not sure if that's the case here, but that is way they are acting about this $1500 restocking fee on a product that never even made it out of customs
