Q: is there an import tax on this to the UK to pay at post office ?

If we are delivering to a UK address, there will be no import tax.

Q: How much would I need to make up 7 litres. I need to make a mold of a plastic head and I have put it in a container to check.

Thank you for your email. 7 litres of Mold Star 20T would be roughly 7.56kgs. I hope that this helps you.
