Step 1: Find out what is the preferential rate offered for your product
Step 2: Find out your product's rules of origin
Rules of origin are a set of criteria which determine a product's originating status in each respective FTA. It is put in place to ensure that only goods originating from the FTA partner countries will benefit from tariff concessions.
Under the TPSEP, an importer would have to prove that the goods are of Singapore origin by presenting a declaration of origin on the export invoice, in order to claim preferential tariffs on the goods in question. Under the Agreement, the Singapore exporter or producer can make this declaration of origin without the need for a formal certificate of origin.
