Ouch, if that is the case this is only going to boost the non US suppliers. Has anyone tried lcsc.com? Digikey and mouser are great but if all semiconductors go up 50% that is a problem.
That said I'm struggling to fully understand it all, the site kind of implies that the 50% Semiconductor tariff _is_ drawbackable - and if we look some of those were in effect since 2024. It does say that the 10% 'China tax' is not.
My reading here then is that the 10% extra is for everyone, and the rest of that table in addition is for goods consumed in the US. (And, some of those tariffs don't look very different from some of them in my non-US locale, which I would have to pay anyway)
Still a daft situation, will for sure be looking around for other suppliers.
That said, shipping was $40-50 for one small box with around 50 components (varying quantities), so if you do order from LCSC it's best to order as much as possible within the same order, since the shipping is gonna be a significant chunk of the cost for any order <$1K. It took a few weeks to arrive using DHL, where Digikey/Mouser both generally deliver within a week (domestic shipping, I'm in N. Carolina).
TLDR; I would recommend LCSC if you are buying enough such that the per-part savings offsets the significantly higher shipping costs, and you don't mind waiting a ~10-14 days for your parts to arrive. I personally still use domestic suppliers for most parts, but when I have a larger BOM and I'm not under a deadline, I'll go with LCSC.
If you're ordering from the US, you should also be aware that Trump's tariffs still apply, so be prepared to pay at least 10% more for everything (some items--things like medical equipment, batteries, and semiconductors--are significantly higher, up to 100%). There may also be a processing fee levied by the shipping carrier if they collect the tariffs on your behalf. As I understand it, LCSC includes a customs declaration form with the shipment, and it's your responsibility to pay any duties or tariffs as the importer.
