Rules of Origin (RoO) are the criteria used to determine the national source of a product. Think of them as a product's “passport,” proving where it was made. This isn't just a fun fact for a label; it's a critical mechanism in international trade. Why? Because access to benefits like lower tariffs or freedom from quotas under a free trade agreement (FTA) depends on a product proving it “originates” from a member country. For instance, for a car assembled in Mexico to be sold in the U.S. without tariffs under the USMCA, it must prove it's “North American” according to the agreement's specific Rules of Origin. This gets complicated quickly. If that car's engine is from Germany and its microchips are from Taiwan, RoO provide the complex legal framework to decide if it still qualifies. For companies, navigating these rules is a high-stakes game that directly impacts their costs and competitiveness.
At first glance, RoO might seem like a topic for trade lawyers, not investors. But for a value investor digging into a company's long-term health, understanding their impact is crucial. These rules can be the difference between a thriving business and one struggling with unforeseen costs. The core issue is how RoO affect a company's cost of goods sold (COGS) and, by extension, its profit margins. A business that masterfully designs its supply chain to comply with RoO for its key markets can ship goods with zero or low tariffs, giving it a powerful price advantage over competitors. This ability to optimize for trade rules can be a subtle but potent part of a company's moat, or durable competitive advantage. Conversely, a company with a rigid supply chain is exposed to significant risk. A political shift leading to a new trade agreement or a crackdown on RoO enforcement could suddenly slap tariffs on its products, crushing margins and sending the stock price tumbling. As an investor, you should assess how exposed a company is to these geopolitical shifts. A prime example is the electric vehicle (EV) industry. The U.S. Inflation Reduction Act provides tax credits to consumers, but only for EVs that meet strict RoO for battery components and minerals. An EV company that can meet these sourcing requirements can offer its cars at a much lower effective price to consumers, directly boosting sales and its stock's potential. A company that fails to do so is left at a major disadvantage.
While the specifics are notoriously complex, the methods for determining origin generally fall into two main categories.
This is the straightforward case. A product is “wholly obtained” if it was entirely grown, born, or extracted in a single country. Think of wheat harvested in France, coffee beans grown in Colombia, or oil drilled in Texas. There's no ambiguity about their “passport.”
This is where it gets tricky. For most manufactured goods, from t-shirts to iPhones, parts and labor come from multiple countries. The product must undergo a “substantial transformation” in one country to claim that country's origin. There are three common ways to prove this:
When analyzing a company that manufactures or sells goods internationally, use RoO as a lens to assess hidden risks and advantages. Ask these questions:
