The purpose of this study is to analyze: 1) what are Rules of Origin in relation to international trade? 2) How are the Rules of Origin regulated in Indonesia? The research method used is empirical juridical with a statutory approach, concept approach, and case studies. The results showed that: 1) Rules of Origin are criteria used to determine the country of origin of an item. This is important because in international trade, obligations and restrictions in some cases depend on the source of import of a good. This Rules of Origin is stated in the form of a Certificate of Origin or Certificate of Origin (SKA) as a document that shows that an item has met the Conditions of Origin of Goods and at the same time is entitled to tariff preferences. 2) Based on two laws, namely Law Number 7 of 2014 concerning Trade and Law Number 10 of 1995 concerning Customs which was amended into Law Number 17 of 2006, it can be said that Indonesia has not set clear rules of origin.
