If you maintain a web page acting as a marketplace through which individuals in Croatia buy goods from suppliers outside the EU, you might need to register for VAT and file monthly returns as if you are the supplier. This applies to goods sold for under €150 and goods kept in an EU warehouse.
If obliged to register for VAT, you can register for the OSS scheme, allowing you to submit monthly VAT returns in one EU member state. You can do this in Croatia.
