Takker for mange bra svar! 
Ja, stemmer. Jeg får jo igjen momsen i Norge. Så da er det bare dobbel shipping som gjelder (fra China til NO, så fra NO til UK).
Dette med VAT er litt merkelig. Jeg på denne UK .gov siden: https://www.gov.uk/guidance/dispatching-your-goods-within-the-eu#vat-within-the-eu-and-with-other-trade-agreement-countries (se tekst i bold):
“The European Free Trade Association’s (EFTA) four member states are Iceland, Liechtenstein, Norway and Switzerland. Three EFTA states (Iceland, Liechtenstein and Norway) belong to the European Economic Area (EEA), uniting the 28 EU countries and the EFTA states in an internal market. The market enables goods and services to move freely in the EEA in an open and competitive environment. Switzerland has separate trade arrangements with the EU. All EFTA members now benefit from virtually the same privileged relationship among themselves as they do with the EU. For trading purposes, goods moved from EFTA countries to EU members states are treated similarly to goods moved between EU member states.”

"[SIZE=5]VAT within the EU and with other trade agreement countries[/SIZE]
If you supply goods to another EU country these sales are technically known as dispatches or removals rather than exports. The term ‘exports’ is reserved to describe sales to a third country outside the EU.
Dispatches within the EU between VAT-registered businesses are not subject to VAT. This also applies to goods imported into the EU that have been released for free circulation following payment of import duties.
However, when you dispatch goods to someone in another EU country, who is not registered for VAT in that country, you should normally charge VAT.
Read about VAT: exports, dispatches and supplying goods abroad.
Customs declarations are not generally required for goods in free circulation within the EU, but traders must remember to raise VAT invoices showing the VAT Registration Number of their customers and obtain evidence of shipment."
Mulig jeg er helt på jordet, men sier ikke dette at man ikke må betale VAT fra Norge → UK? Ref "other trade agreement countries)
