USA won't ship to UK because of Brexit?

What are you talking about

 nothing to do with VAT - VAT in the UK is the same now as it was before brexit

Possibly its due to shipping costs

Its possible they have always shipped via europe

In which case the goods will still be shipped to europe, but NOW will have to go from europe to the UK via customs

and THAT would add to shipping costs as a direct result of brexit

(i.e any vat on goods bound for UK will have to be reclaimed on entry to europe then paid to HMRC on entry to the UK

 This could also get a bit tricky since europe may charge different rates of VAT than the UK charges depending what the goods are)

You didn't notice anything.  Stop making up crap and go away.

Most U.S. places have no problem shipping to the UK.  Some things might be available there though and to ship an identical item would not be cost effective.  If you are willing to pay a high shipping cost, they will probably ship it but, they have already figured it out - they can buy it there for considerably less.

No nothing to do with Brexit more likely to do with this which is increases in tariffs https://www.theguardian.com/business/2021/mar/29/u...

wont they guess the u.s. mustnt want a market of 100 million people , guess things in america are better of without the english money . What a silly statement guess you like your money going to china then .

It’s not newly added. 

US suppliers to EU countries were obliged to collect VAT on EU sales long before Brexit.

The exemptions for low volume and low value sales are also unchanged. But some of the exact software and paperwork may have changed, and some sellers will be reluctant to spend time and money to check whether they’re still compliant.

It’s no big deal. They can still sell to you if they want to, filling in the usual Customs Declaration form affixed to the outside of the package. That says what the goods are, their value, and their weight. UK Customs then examine the form check the contents if necessary, and then issue a notice to Royal Mail to collect VAT and any import duties before the package can be released for delivery.

Nothing to do with Brexit as the US was not part of the EU.

They may not have the authority to collect the VAT, their software my not be set up to process it - there's any number of reasons. Brexit affects the UK and the EU. We really don't care.

Not bad...they are racist.
