Step 1: 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 USSFTA, it is the importer who makes a claim for preferential treatment. The information regarding its qualification as originating good has to be submitted by the exporter to the importer. The Singapore exporter has to self-certify that the product originated from Singapore. There is no prescribed format for the self-certification.
