I think it's the £130 threshhold that probably saves the day there Angus.
It's certainly often tougher, going the other way. I was a bit irked to have to pay 25€ for a Christmas present sent to the wife by her brother from the UK! Which meant both countries got the VAT, the French picked up their admin fee, etc.
But it's a lottery. Some stuff just comes no hassle, while other items of similar declared value get caught.
If goods coming here are made in the UK, there should be no customs charge at least, but that isn't always made clear or respected either.
Postie won't leave anything on which taxes are said to be due, what's more. So if you want to argue, it has to be after the event. Refusal to accept a package doesn't work too well either - I took one argument to the stage where the 'huissiers' (bailiffs) were threatening to drop by before I surrendered. That was from the USA.
For these and the related admin reasons at the despatch end, I can quite see why many businesses won't sell into the EU. CB's latest comment says it all.
There are also other countries to which many businesses won't send things for reasons of incompetent postal services, theft en route and so on.
South America is hard, South Africa is a nightmare these days, as are parts of Asia, and even the USA can be problematic.
Globalisation is just a word really.
