I'm always curious to hear what real-world numbers are like around any new tariffs and here's keyboard.io explaining how if Trump actually goes through with it, prices would double for their high-end keyboards (with no additional profit, all money goes to tariff charges) https://shop.keyboard.io/blogs/news/an-open-letter-to-u-s-customers
If you want to get a sense of what it costs to hand assemble keyboards in the USA, take a look at Norbauer & Co’s Seneca keyboard. It’s gorgeous and beautifully made. It’s also priced at $3600.
