Is anyone having difficulty purchasing products from outside the U.S.?

In early April I ordered an r-core power supply along with a silver plated DC supply cable and a pure silver USB cable from China. The cables arrived on time as expected. The information on shipping for the power supply was sketchy. I was notified shortly after purchase that it would arrive between April 18-25. There was no further update on tracking so on 4/15 I contacted the seller on Aliexpress. This is what they said:

“Hello,

So sorry.

This power supply has not been sent yet. It will take about 3 more days.

Best Regards”

On 4/18 the tracking information indicated the product had shipped. The order information was not updated and still stated it would arrive between April 18 and 25. April 25 came and went, no power supply, no tracking update. On 4/27 I contacted the seller and asked for an update. This is what they said:

”Hello

Sorry, due to the new US tariff policy, we were unable to send this package.

We currently do not have suitable logistics transportation to the United States, and packages arriving in the United States will incur huge tariffs.

You can apply for a refund.

Sorry again

Thank you for your understanding and support

Best Regards”

There you have it. The heavier power supply probably had to be sent by marine transportation and the timing was such it would land in the U.S. after the tariffs went into full effect. The lighter cables on the other hand probably shipped via air freight and arrived ahead of the tariffs. Imagine how this is now playing across all the components and finished electronics products across the market today. There will be disruptions. Likely very large disruptions.

During covid I started a hobby assembling my own power cables from parts. That is when I stumbled onto Aliexpress. Covid disruptions of shipping meant very long arrival times for products, up to six weeks or more. This feels very different, and if not resolved the current situation is likely to significantly raise prices or essentially eliminate access for many products in the audio industry.

In the meantime, does anyone know where I can buy a U.S. made 5V r-core external power supply with quality parts for $115 including all sales taxes and shipping? Or for two or three times that much? If you find out, please let me know.

Thanks,

Best way would be searching eBay, but specify location within the U.S. or North America. Amazon sellers might have one warehoused in the U.S. too. Places like Aliexpress haven't been helpful. I just placed an order for a Hifiman Edition XS and said "Ships from U.S." and it said will ship in 33 days, so it's total mayhem at those vendors. Google Shopping might help, or now Google defaults to "all", but if you check the "Web" tab you'll have better luck finding a supplier in the U.S. that would have them. Maybe Mercari or Facebook marketplace if bored/desperate...

You may need to build your own PSU then if you insist on an R-Core transformer. Linear PSU's are relatively simple designs, which just leaves you with a transformer to source from somewhere.

Custom Magnetics are a US-based manufacturer of transformers (incl. R-Core):

Business opportunities for you!
LOL. I just want to buy one and see how it compares to the toroidal supplies I already own. Great idea though, maybe someone in the U.S. will take you up on that right after they determine how to re-source everything on the shelves of Walmart and Target with domestic alternatives. I predict that will take a minute.

@dunring I just checked eBay and couldn’t find any 5V r core power supplies shipping from the U.S. I did find this:

“TeraDak 30W R Core Transformer HiFi Linear Power Supply 5V/6V/7V/9V/12V Optional

$62.00 + $280.00 shipping”

Wow.
